A landmark former orphanage site in Surrey Hills could be transformed into a new residential community under plans lodged by <a href="https://www.apartments.com.au/developers/antipodean-land-developments">Antipodean Land Developments</a> that would deliver 76 apartments and townhouses while restoring some of the suburb's most significant heritage buildings.

The burgeoninng Melbourne-based developer has submitted plans for the 9,158 sqm site at 1 Kent Road and 24 Durham Road, home to the former St Joseph's Home for Destitute Children, a historic institutional complex dating back to the late 19th century. The proposal seeks to adaptively reuse several heritage buildings while introducing two new four-storey residential buildings set within extensive landscaped grounds.

Designed by <a href="https://www.apartments.com.au/architects/woods-bagot">Woods Bagot</a> and Kerstin Thompson Architects, the project has been conceived as a contemporary residential village embedded within a restored heritage precinct. The development team describes the design approach as "The Village in the Garden," with new buildings positioned among mature landscaping by OCULUS and significant heritage structures.

The proposal would deliver 76 dwellings comprising a mix of apartments and duplex-style residences, significantly increasing housing supply on one of the largest privately held residential landholdings in Surrey Hills. The development includes 127 car spaces, 24 bicycle spaces and more than 1,000 sqm of communal amenity, with the existing chapel building earmarked for conversion into resident facilities.

According to the planning submission, the project centres on the restoration and adaptive reuse of the site's most significant heritage assets, including the original c.1889 St Joseph's building, the chapel designed by architect Augustus Andrew Fritsch, and the historic brick perimeter walls and entry gates. The proposal also incorporates the retention of other contributory buildings including the former infirmary and school building.

Tract Consultants, in the planning report accompanying the application, said the scheme had been shaped through extensive heritage analysis and design development.

"The shared vision for the Site by the project team has culminated in a scheme which successfully breathes life back into a historic site while delivering upon the objectives of Victoria's Housing Statement in a carefully curated and contextually responsive manner."

The proposal is being assessed under Victoria's Significant Residential Development with Affordable Housing pathway. As part of the application, three per cent of the project's residential development cost would be contributed to the Social Housing Growth Fund. The development would also provide a diverse mix of one, two and three-bedroom residences targeting a broader range of buyers than typically found in Surrey Hills' detached housing market.

Sustainability initiatives include an anticipated 66 per cent BESS score, natural cross-ventilation to 80 per cent of apartments, 28 per cent deep soil landscaping and a canopy cover outcome exceeding local planning requirements. The proposal also sets aside more than 1,083 sqm for communal indoor and outdoor resident amenity spaces.

Planning documents describe the property as one of the largest underutilised residential sites in Surrey Hills, arguing it presents a rare opportunity to introduce "missing middle" housing in an established inner-eastern suburb while preserving and revitalising a significant heritage precinct.

Antipodean Land Developments has built a reputation for design-focused residential projects across Melbourne, particularly in the medium-density sector. Previous developments include Neighbourhood in Brunswick East, delivered with Breathe Architecture, and Balfe Park Lane, designed by Kerstin Thompson Architects.

They've been very active in site acquisition as they build out their future development pipeline. They recently launched Thornubury House, 45 apartments above a mix of commercial, retail, and food and beverage tenancies, and have plans for a boutique project in Fitzroy and another <a href="https://www.apartments.com.au/news/vic/antipodean-plan-apartments-for-deepdenes-missing-middle-on-whitehorse-road">"missing middle" project</a> on Deepdene's Whitehorse Road.

Developer <a href="https://www.apartments.com.au/developers/auyin-property-development">Auyin</a> is the latest to turn to the Victorian Government's Development Facilitation Program in an effort to secure approval for its long-planned, mixed-use project in Elsternwick.

In 2018, Auyin lodged plans with Glen Eira City Council for a 14-storey building, however Council approved a reduced eight-storey scheme. A subsequent VCAT appeal in 2019 upheld the eight-storey height limit.

The project was later amended to nine storeys, but Auyin is now seeking to revive something closer to its original vision. The developer argues that the planning context has evolved significantly over the past decade, particularly within the Elsternwick Activity Centre, where higher-density development has increasingly been encouraged along Glen Huntly Road.

The proposal would transform the 1,239 sqm site at <a href="https://www.apartments.com.au/new-apartments/7-12-horne-street-elsternwick-vic-3185">7-15 Horne Street</a>, opposite Elsternwick Railway Station, into a 13-storey residential and retail development designed by CBG Architects, with 40 apartments

The site currently comprises three commercial properties.

<img alt="First look: 13-storey mixed-use tower planned for Elsternwick activity centre" data-entity-type="file" data-entity-uuid="5f465dd4-509b-4082-a669-0253b313914b" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/elsternwick%20podium.png?VersionId=72frWi0SmQ5AVJ3ARRhX5ILUYObhTm7x" />

The proposed apartment mix comprises 25 two-bedroom and 15 three-bedroom residences above 200 sqm of retail space at ground level. Residents would have access to a 90 sqm wellness facility, a 351 sqm communal indoor and outdoor terrace on the third level, and extensive landscaped areas throughout the development. A publicly accessible 135 sqm plaza would be created on the north-east corner of the site, providing seating, landscaping, and a new gathering space adjoining Horne Street.

The design adopts a four-storey podium that references the finer-grain character of the surrounding streetscape, with the upper tower recessed behind generous setbacks on all boundaries.

<img alt="First look: 13-storey mixed-use tower planned for Elsternwick activity centre" data-entity-type="file" data-entity-uuid="e637e763-2abc-4c34-a0aa-5c7ad36fae18" src="https://s3.ap-southeast-2.amazonaws.com/www.urban.com.au/s3fs-public/inline-images/elsternwick%20open.png?VersionId=J1AoOpZgTyaF.KeeFSX6lMjEScX8KKRi" />

A key element of the proposal is the reconfiguration and widening of the surrounding laneways. Vehicle access would be retained from Lois Lane, with upgraded pedestrian connections linking Ross Street and Horne Street. The development would provide 58 residential car spaces, two retail car spaces, and 52 bicycle spaces across two basement levels and ground-floor facilities.

Architecturally, the building draws inspiration from the established character of Elsternwick Village. The façade combines dark charcoal brickwork, textured concrete, bronze-toned metal detailing, and extensive planting integrated into podium and tower levels. The design also incorporates a chamfered corner treatment and publicly accessible plaza intended to strengthen pedestrian activity around the station precinct.

Elsternwick's last new development completion was&nbsp;EVA Elsternwick by Pitard late last year. <a href="https://www.apartments.com.au/developers/milieu-property">Milieu</a> is working away on its nature-led neighbourhood, <a href="https://www.apartments.com.au/new-apartments/elsternwick-gardens-by-milieu-8-gordon-street-elsternwick-vic-3185">Elsternwick Gardens</a>, on Gordon Street, with its first stage expected to complete next year.

<a href="https://www.apartments.com.au/new-apartments/otium-parkdale-123-125-como-parade-east-parkdale-vic-3195">Otium Parkdale</a>, the 13-residence boutique development by&nbsp;<a href="https://www.apartments.com.au/developers/huxtable-property">Huxtable Property</a>, has entered its final stages of delivery, with completion expected within the coming month and more than half of the residences sold.

The Como Parade East project is nearing the finish line at a time when opportunities to purchase new apartments in <a href="https://www.apartments.com.au/developments/parkdale-vic-3195">Parkdale</a> remain exceptionally limited. Fewer than 10 per cent of dwellings in the bayside suburb are apartments, making developments like Otium a relatively rare addition to a market traditionally dominated by detached housing.

[smartcode_project:default project_id=134974 project_image_fid=5427]

The three-level development comprises 13 residences, including ten two-bedroom apartments and three larger three-bedroom homes, all positioned above a secure basement car park.

Designed by <a href="https://www.apartments.com.au/architects/almeida-architects">Almeida Architects</a> with a strong connection to its coastal surroundings, Otium combines red brick, exposed concrete and dark metal detailing with integrated landscaping and greenery. Expansive glazing, generous balconies and terraces have been incorporated throughout the design to maximise natural light and reinforce indoor-outdoor living.

Inside, the residences feature engineered European oak flooring, natural and reconstituted stone benchtops, Bosch kitchen appliances, ducted heating and cooling, lift access and secure entry systems. The larger three-bedroom residences on the upper level have been designed with house-like proportions, while the two-bedroom apartments prioritise functionality, flexibility and low-maintenance living.

[smartcode_project:default project_id=134974 project_image_fid=5421]

The project is now in its final stages, with <a href="https://www.apartments.com.au/builders/labco">Labco</a> completing the remaining landscaping and external finishing works following the completion of the residences' interiors.

Otium's location within the heart of Parkdale continues to underpin its appeal. Residents will be just steps from local cafés, restaurants, shops and the newly elevated Parkdale Station, while the beach is less than a kilometre away.

With the project tracking ahead of schedule, buyers can currently secure a residence with a five per cent deposit and benefit from settlement terms of up to eight months. The advanced stage of construction also provides buyers with the opportunity to walk through the near-complete residences and experience the quality and finishes firsthand ahead of completion.

A new boutique apartment development is entering the market in <a href="https://www.apartments.com.au/developments/chermside-qld-4032">Chermside</a>, with Brisbane-based developer <a href="https://www.apartments.com.au/developers/ausdev">Ausdev</a> bringing 33 residences to a well-connected pocket of Brisbane's north.

<a href="https://www.apartments.com.au/new-apartments/parkdrive-apartments-chermside-25-sammells-drive-chermside-qld-4032">Parkdrive Apartments</a>, at 25 Sammells Drive, will comprise a mix of one- and two-bedroom residences positioned within walking distance of Westfield Chermside, The Prince Charles Hospital, and Bradbury Park.

Established in 1989, Ausdev has a long-standing presence across both development and construction, with Parkdrive Apartments representing its latest residential project in Brisbane's northern suburbs.

[smartcode_project:default project_id=152125 project_image_fid=363778]

The development has been designed around open-plan living and natural light, with residences featuring stone benchtops, timber cabinetry, BOSCH appliances, and private balconies that extend the living areas outdoors.

Kitchens are positioned as the centrepiece of the homes, incorporating natural material palettes and integrated appliances, while bathrooms have been designed with a focus on functionality and understated finishes.

Residents will have access to a communal barbecue and entertaining area on Level 3, providing shared outdoor space within the development. Secure parking and lift access are also incorporated into the building.

The project will deliver a limited collection of 33 apartments, with one-bedroom residences priced from $749,000.

[smartcode_project:default project_id=152125 project_image_fid=363782]

Beyond the building itself, the location places residents within easy reach of several of Chermside's key amenities. Bradbury Park is around 350 metres away, while Westfield Chermside is approximately 1.3 kilometres from the site. The Prince Charles Hospital is located within 750 metres, and the Chermside Bus Interchange is around 1.5 kilometres away, providing connections across Brisbane.

Parkdrive Apartments adds to the growing residential pipeline in Chermside, a suburb that continues to evolve as a major retail, healthcare, and transport hub for Brisbane's north.

<a href="https://www.apartments.com.au/developers/skymark-group">Skymark</a>'s boutique Cronulla development Solis has secured a 10-year Latent Defects Insurance policy through Resilience Insurance, providing buyers of the 16-residence building on Ewos Parade with structural and waterproofing protection that extends a decade beyond the building's completion.

Currently under construction and due for completion in late 2027, <a href="https://www.apartments.com.au/new-apartments/solis-cronulla-8-ewos-parade-cronulla-nsw-2230">Solis</a> is one of a small number of new developments in the Sutherland Shire to carry Resilience LDI coverage, a distinction that carries increasing weight as buyer confidence in the off-the-plan sector continues to be shaped by how developers stand behind their product.

Latent Defects Insurance, which entered the Australian market in 2022 when Resilience Insurance was approved to offer the cover, protects buyers against major structural or waterproofing defects for ten years post-completion. Unlike traditional statutory warranties, it operates as a first-resort policy, if a covered defect arises, the insurer responds directly, without the buyer needing to pursue the builder or developer through a lengthy claims process.

Resilience Insurance CEO Corey Nugent has noted that the product addresses something fundamental to the new apartment market.

"The overarching feedback from prospective buyers in the new development space is that they want more confidence and assurances around the quality of the build," Nugent says.

"Resilience Insurance Latent Defects Insurance not only gives them complete peace of mind for 10 years, but it shows the developer they are buying from is standing by their product."

[smartcode_project:default project_id=150499 project_image_fid=370898]

For Solis, the Resilience LDI policy adds a meaningful layer of accountability to an already considered project. The development comprises nine two-bedroom and seven three-bedroom residences, including one dual-level three-bedroom apartment, across a five-storey building on Ewos Parade, positioned between Shelly Beach and South Cronulla.

Garden apartments connect directly to private landscaped courtyards, while upper-level homes capture beach views to the east from level four and above.&nbsp;

All 16 residences include at least one balcony or courtyard, and select apartments on the upper floors feature bar areas and secondary flexible living spaces.

Hiba Sander, Managing Director of Skymark, says Solis offers a rare balance, nestled between the quiet beauty of secluded beaches and the lively charm of South Cronulla's esplanade.

"It's a place to choose your pace and live gracefully, seaside'," Sander says.

[smartcode_project:default project_id=150499 project_image_fid=370900]

The architecture, designed by <a href="https://www.apartments.com.au/architects/ida-design-group">IDA Design Group</a>'s Michael Trinh, draws from the natural erosion patterns of <a href="https://www.apartments.com.au/developments/cronulla-nsw-2230">Cronulla</a>'s sandstone headlands, translating the organic forms of the coastline into soft curves, pavilion-style massing, and a material palette chosen for longevity in a salt-tinged environment.&nbsp;

Textured natural stone, soft renders, and timber-look battens reference the tones of the surrounding cliffs, while the building has been oriented to maximise natural light and passive ventilation, with primary living spaces facing north and east to capture morning sun and sea breezes.

"At Solis, our aim was to create architecture that feels quietly confident, grounded in natural materials like stone and timber, and elevated by light and landscape," Trinh says.&nbsp;

"The buildings are designed to sit gently within their coastal surrounds, with expansive glazing and abundant greenery creating a seamless dialogue between inside and out."

[smartcode_project:default project_id=150499 project_image_fid=370897]

Interiors by <a href="https://www.apartments.com.au/architects/hot-black">Hot Black</a> carry the same material language through to every room. Kitchens feature integrated Gaggenau appliances, sculpted stone benchtops, and Lo &amp; Co joinery, while bathrooms feature natural stone, timber, and brushed metal finishes.&nbsp;

Hot Black Founder and Design Director Sophie Safrin describes the intent as one of considered restraint: "At Solis, every detail has been thoughtfully considered to create a timeless coastal retreat, calm, refined, and effortlessly liveable. From natural finishes to seamless indoor-outdoor flow, Solis offers a quiet elegance that's deeply connected to its surroundings.

The landscape, designed by Julian Brady of <a href="https://www.apartments.com.au/landscape-architect/sitedesignstudios">Site Design Studios</a>, treats green space as an integral part of the resident experience rather than an afterthought.&nbsp;

"Gentle curves and layered native plantings mirror the ebb and flow of the ocean," Julian Brady says, "creating a serene connection between architecture and place."&nbsp;

Coco Republic has provided bespoke furniture packages tailored to the project's coastal palette.

[smartcode_project:default project_id=150499 project_image_fid=370899]

Skymark has an established track record in the Sutherland Shire, with a portfolio spanning Cronulla, Woolooware and Burraneer that includes Isla, Sylva, Bask, Shells, Sula and Mist. Securing LDI on Solis reflects a broader shift in how the developer is positioning its buildings to buyers, at a time when Resilience Insurance expects the policy to become mandatory in New South Wales by 2028.

Sales at Solis are launching soon through Ray White Projects, with an official event scheduled for 11 June. Enquire for more information.

Solar Power

GUEST OBSERVATION
In Australia, renewable energy is growing at a per capita rate ten times faster than the world average. Between 2018 and 2020, Australia will install more than 16 gigawatts of wind and solar, an average rate of 220 watts per person per year.
This is nearly three times faster than the next fastest country, Germany. Australia is demonstrating to the world how rapidly an industrialised country with a fossil-fuel-dominated electricity system can transition towards low-carbon, renewable power generation.

We have <a href="https://energy.anu.edu.au/files/Renewable%20energy%20target%20report%20September%202019_1_0.pdf" target="_blank">analysed</a> data from the regulator which tracks large- and small-scale renewable energy generation (including credible future projects), and found the record-high installation rates of 2018 will continue through 2019 and 2020.
<h2>Record renewable energy installation rates</h2>
While <a href="https://theconversation.com/australia-has-met-its-renewable-energy-target-but-dont-pop-the-champagne-122939" target="_blank">other analyses</a> have pointed out that investment dollars in renewable energy fell in 2019, actual generation capacity has risen. Reductions in building costs may be contributing, as less investment will buy you the more capacity.
Last was a record year for renewable energy installations, with 5.1 gigawatts (GW) accredited in 2018, far exceeding the previous record of 2.2GW in 2017.
The increase was driven by the dramatic rise of large-scale solar farms, which comprised half of the new-build capacity accredited in 2018. There was a tenfold increase in solar farm construction from 2017.
We have projected the remaining builds for 2019 and those for 2020, based on data from the Clean Energy Regulator for public firm announcements for projects.
A project is considered firm if it has a power purchase agreement (PPA, a contract to sell the energy generated), has reached financial close, or is under construction. We assume six months for financial close and start of construction after a long-term supply contract is signed, and 12 or 18 months for solar farm or wind farm construction, respectively.
This year is on track to be another record year, with 6.5GW projected to be complete by the end of 2019.
The increase is largely attributable to a significant increase in the number of wind farms approaching completion. Rooftop solar has also increased, with current installation rates putting Australia on track for 1.9GW in 2019, also a new record.
This is attributed to the continued cost reductions in rooftop solar, with less than A$1,000 per kilowatt now considered routine and payback periods of the order of two to seven years.
<a href="https://images.theconversation.com/files/292954/original/file-20190918-187985-r9h3yc.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/292954/original/file-20190918-187985-r9h3yc.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Current (solid) and forecast (hashed) installations of renewable electricity capacity in Australia. Author provided
Looking ahead to 2020, almost 6GW of large-scale projects are expected to be completed, comprising 2.5GW of solar farms and 3.5GW of wind. Around the end of 2020, this additional generation would deliver the old Renewable Energy Target of 41,000 gigawatt hours (GWh) per annum. That target was legislated in 2009 by the Rudd Labor government but <a href="https://www.aph.gov.au/About_Parliament/Parliamentary_Departments/Parliamentary_Library/pubs/BriefingBook45p/RenewableEnergy" target="_blank">reduced to 33,000GWh</a> by the Abbott Coalition government in 2015.
<h2>Maintaining the pipeline</h2>
There are strong prospects for continued high installation rates of renewables. Currently available renewable energy energy contracts are routinely offering <a href="https://reneweconomy.com.au/snowy-says-cost-of-firm-wind-and-solar-significantly-below-current-base-load-prices-76846/">less than A$50 per MWh</a>. Long-term contracts for future energy supply have an average price of more than A$58 per MWh. This is a very reasonable profit margin, suggesting a <a href="https://www.asx.com.au/products/energy-derivatives/australian-electricity.htm">strong economic case</a> for continued installations. Wind and solar prices are likely to decline further throughout the 2020s.
State governments programs are also supporting renewable electricity growth. The ACT has completed contracts for 100% renewable electricity. Victoria and Queensland both have renewable energy targets of 50% renewable electricity by 2030. South Australia is expecting to reach 100% by 2025.
The main impediment to continued renewables growth is transmission. Transmission constraints have resulted in bottlenecks in moving electricity from some wind and solar farms to cities.
Tasmania’s strong wind resource requires a new connection to the mainland to unlock more projects. The limitations of current planning frameworks for this transition were recognised in Chief Scientist Alan Finkel’s review of the National Electricity Market, with strong recommendations to overcome these problems and, in particular, to <a href="https://www.energy.gov.au/publications/independent-review-future-security-national-electricity-market-blueprint-future" target="_blank">strengthen the role of the Australian Energy Market Operator</a>.
Now we need state and federal governments to unlock or directly support transmission expansion. For example, the <a href="https://www.dnrme.qld.gov.au/energy/initiatives/poweringqueensland#targetText=The%20Powering%20Queensland%20Plan%20sets,and%20secure%%2020supply%20of%20electricity" target="_blank">Queensland government</a> has committed to supporting new transmission to unlock solar and wind projects in the far north, including the Genex/Kidston 250MW pumped hydro storage system. The New South Wales government will expedite planning approval for an <a href="https://www.transgrid.com.au/news-views/news/2019/Pages/Project-EnergyConnect-deemed-critical-infrastructure-in-NSW.aspx">interconnector</a> between that state and South Australia, defining it as “critical infrastructure”.
These investments are key to Australia maintaining its renewable energy leadership into the next decade.<img src="https://counter.theconversation.com/content/123694/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1" style="border: none !important; box-shadow: none !important; margin: 0 !important; max-height: 1px !important; max-width: 1px !important; min-height: 1px !important; min-width: 1px !important; opacity: 0 !important; outline: none !important; padding: 0 !important; text-shadow: none !important;">

Australia is the runaway global leader in building new renewable energy

<html><body>
GUEST OBSERVATION
Many of us are familiar with developments of big solar farms in rural and regional areas. These are often welcomed as a positive sign of our transition towards a low-carbon economy. But do large-scale solar installations have a place in our cities?
The City of Fremantle in Western Australia is considering a proposal to use a former landfill site for a large-scale solar farm. The reportedly 4.9 megawatt solar power station on an eight-hectare site would be, it’s said, Australia’s largest urban solar farm. The initiative is part of Fremantle’s ambition to be powered by 100% clean energy within a decade.
The proposal is facing some community opposition, however. Residents are reportedly alarmed by the potential public health consequences of building on a rubbish dump, which risks releasing toxic contaminants such as asbestos into the environment. Other concerns include glare from the solar panels, or excessive noise.
Similar complaints about solar panels in cities are being seen all over the world, with opponents generally of the view “they do not belong in residential areas”. So what are the planning issues associated with large-scale solar installations in cities? And should we be concerned about possible negative impacts?
What is large-scale solar?
According to the Australian Clean Energy Regulator, large-scale solar refers to “a device with a kilowatt (kW) rating of more than 100 kilowatts”. A kilowatt is a measure of power – the rate of energy delivery at a given moment – whereas a kilowatt-hour (kWh) is a measure of the total energy produced (so a 100kW device operating for one hour would produce 100kWh of electricity).
Device here refers to not only the photovoltaic (PV) panels – the actual panels used in solar energy – but also to the infrastructure “behind the electricity meter”. So interconnected panels may still constitute a single device.
By this definition, there may already be large-scale solar installations in Australian cities. In Sydney for example, the recently opened system on top of the Alexandra Canal Transport Depot is by all accounts a large-scale solar system. It combines around 1,600 solar panels with enough battery storage for 500kWh of electricity.
But this is not Sydney’s largest solar installation. That honour is presently held by the Sydney Markets in Flemington, among Australia’s largest rooftop solar installations, which generates around 3 megawatts (that’s 3,000kW). To date, there have been no publicly disclosed complaints received about these facilities.
Large-scale solar (sometimes called “big solar”) can also refer to solar arrays that use mirrors to concentrate sunlight onto solar PV panels. This is different to concentrated thermal solar, which uses mirrors to focus sunlight onto the top of a tower to heat salt, oil or other materials that can then be used to generate steam to power turbines for electricity generation.
What’s the problem with solar in cities?
Internationally, there is increasing recognition cities could be ideal locations for large-scale solar installations due to the amounts of unused land. This includes land alongside freeways and main roads, flood-prone land, and rooftops on factories, warehouses and residences. And locating big solar in cities can also reduce the energy losses that occur with transmitting electricity over long distances.
Australia’s combined rooftop solar installations already supply the equivalent of enough power for all the homes in Sydney. And even former landfill sites – which have few uses other than parkland and are often too contaminated to sustain other land uses such as residential development – can be a good use of space for solar farms. But such sites would need to be carefully managed so contaminants are not released during construction.
Large-scale solar installations can present some challenges for urban planning. For instance, mirrors can cause problems with glare, or even damage if they were misaligned (problems thus far have been in solar thermal plants). Maintenance vehicles may increase traffic in neighbourhoods. Installing solar panels could cause temporary problems with noise and lighting. And views could potentially be disrupted if adjoining residents overlook a large-scale solar installation.
But not all of these impacts would be long-term, and they can all potentially be managed through planning approval, permitting processes and development conditions. Installing screens or trees can improve views, for instance. Glare is a potential problem but again can be managed via screening (at the site or on overlooking buildings) or protective films on the panels.
The issue with the proposed solar farm in Fremantle is the fact it’s planned atop a former landfill site, known to contain harmful substances including asbestos, hydrocarbons and heavy metals. Unless carefully managed, construction of the solar farm could disturb these materials and potentially expose nearby residents to health impacts.
Most state environmental protection agencies recognise risks if the use of potentially contaminated land is to be changed, and have developed stringent guidelines for landfill management.
The City of Fremantle has approved the proposed development, subject to the preparation of a site management plan among other conditions. Depending on site management, and the characteristics of surrounding neighbourhoods, poorly managed big solar on landfill sites could become an environmental justice issue. From this perspective, residents’ concerns are understandable, and the City of Fremantle will need to ensure it carefully monitors construction.
Lessons for planning
It is reasonable to expect that cities will increasingly host large-scale solar installations. With careful site selection and management, the multiple benefits of clean energy can accrue to urban residents. Otherwise leftover or marginal land can derive an economic return.

But solar farms also have the potential to provide new habitats both via physical infrastructure (sites for nesting) and as part of site rehabilitation and management.

If done right, our solar cities can succeed: Jason Byrne

EXPERT OBSERVER
The keenly awaited <a href="https://www.accc.gov.au/publications/restoring-electricity-affordability-australias-competitive-advantage" target="_blank">report on retail electricity prices</a>, released last week by the Australian Competition and Consumer Commission (ACCC), has made some controversial recommendations – not least the call to wind up the scheme that offers incentives for household solar nearly ten years early.
The report recommends that the small-scale renewable energy scheme (SRES) should be abolished by 2021. It also calls on state governments to fund solar feed-in tariffs through their budgets, rather than through consumers’ energy bills.
The ACCC has concluded that offering subsidies for household solar was a well-intentioned but ultimately misguided policy. Solar schemes were too generous, unfairly disadvantaged lower-income households, and failed to adjust to the changing economics of household solar.
The lesson for policy-makers is that good policy must keep costs down as Australia navigates the transition to a low-emissions economy in the future. Failure to do this risks losing the support of consumers and voters.
Runaway rebates
Rooftop solar schemes were much <a href="https://grattan.edu.au/wp-content/uploads/2015/05/822-sundown-sunrise5.pdf" target="_blank">more popular than anticipated</a>. This might sound like the sign of a good policy. But in reality it was more like designing a car with an accelerator but no brakes.
Generous feed-in tariffs and falling small-scale solar installation costs encouraged more households to install solar than were initially expected. Premium feed-in tariffs were well above what generators were paid for their electricity production. Historically solar feed-in tariffs paid households were between 16c and 60c per kilowatt-hour, while wholesale prices were <a href="https://grattan.edu.au/report/mostly-working/" target="_blank">less than 5c per kWh</a>.
At the same time, <a href="https://www.accc.gov.au/publications/restoring-electricity-affordability-australias-competitive-advantage" target="_blank">installation costs for solar panels fell</a> from around A$18,000 for a 1.5kW system in 2007, to around A$5,000 for a 3kW system today. The SRES subsidy for solar installations was not linked to the actual installation cost or the cost above the break-even price. So the SRES became relatively more generous as installation costs fell.
As solar penetration increased, and network costs rose to cover this, it became <a href="http://energyconsumersaustralia.com.au/news/consumers-investing-in-solar-and-batteries-to-control-bills/" target="_blank">increasingly attractive</a> for households to install solar panels. In Queensland, the initial cost forecast for the solar bonus scheme was A$15 million. Actual payments were more than 20 times that in 2014-15, at A$319 million. And the environmental benefits weren’t big enough to <a href="https://grattan.edu.au/wp-content/uploads/2015/05/822-sundown-sunrise5.pdf" target="_blank">justify that cost</a>, as other policies have reduced emissions at a lower cost. The large-scale renewable energy target reduced emissions for A$32 per tonne, while household solar panels reduced emissions at a cost of more than A$175 per tonne.
In most states, premium feed-in tariffs and rooftop solar subsidies are funded through higher bills for all consumers. Everyone pays the costs, yet only those with panels receive the benefits. That means the costs fall disproportionately on lower-income households and those who rent rather than own their home.
The ACCC report recommends the SRES be wound up nearly 10 years ahead of schedule, because the subsidies are no longer financially justifiable. This would maintain the support for current solar installations but remove subsidies for new solar installations from 2021.
The report also recommends removing the direct costs of feed-in tariffs from electricity bills. Instead, state governments should directly cover the costs of premium feed-in tariffs. The Queensland government has already <a href="https://www.dnrme.qld.gov.au/energy/initiatives/powering-queensland" target="_blank">made this move</a>.
Of course, governments still have to find the money from elsewhere in their revenues, which means taxpayers are still footing the bill. But the new arrangement would at least remove the current unfair burden on households without solar.
Fixing the mistakes
How can governments avoid making similar policy mistakes in the future? The ACCC’s recommendations, together with the proposed <a href="https://theconversation.com/infographic-the-national-energy-guarantee-at-a-glance-85832" target="_blank">National Energy Guarantee (NEG)</a>, provide a solid foundation for Australia’s future energy policy.
First, the future is hard to predict, so good policy adapts to change. The NEG provides a flexible framework to direct energy policy towards a low-emission, high-reliability, low-cost future. Reviewing and adjusting the emissions target along the way will enable Australia’s energy policy to respond to new technologies and shifting cost structures, while maintaining consistency with economy-wide targets.
Second, it is hard to pick winners, so good policy creates clear market signals. The NEG provides the energy industry with clear expectations, but is technology-agnostic and minimises government intervention. This encourages the market to find the most cost-effective way to reduce emissions and ensure reliability.
The ACCC report also recommends simplifying retail electricity offers, which would make it easier for consumers to find a good deal, and in turn making the market more competitive.
<img src="https://counter.theconversation.com/content/99937/count.gif?distributor=republish-lightbox-basic" alt="The Conversation" width="1" height="1">Politicians have an opportunity to draw a line in the sand on narrow, technology-specific policies such the SRES. An integrated energy and climate policy should focus on good design, and then step back and let the market pick the winners.

Why the ACCC says household solar subsidies should be abolished

<html><body>
The rate of growth in residential rooftop solar photovoltaics (PV) in Australia since 2008 has been nothing short of breathtaking.
Our new research suggests that the households most likely to join in the solar spree are those that are affluent enough to afford the upfront investment, but not so wealthy that they don’t worry about their future power bills.
Australia now has the <a href="https://www.propertyobserver.com.au/http://pv-map.apvi.org.au/historical#4/-26.67/134.12" target="_blank">highest penetration</a> of residential rooftop PV of any country in the world, with the technology having been installed on one in five freestanding or semi-detached homes. In the market-leading states of Queensland and South Australia this ratio is about one in three, and Western Australia is not far behind, with one in four having PV.
<a href="https://images.theconversation.com/files/221436/original/file-20180603-142072-rsg9fx.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/221436/original/file-20180603-142072-rsg9fx.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
The explosion in rooftop PV uptake since 2008. Derived from Clean Energy Regulator data.
While PV panels give households more control over their electricity bills, and each new installation helps reduce greenhouse gas emissions, the market’s rapid expansion has posed <a href="https://theconversation.com/slash-australians-power-bills-by-beheading-a-duck-at-night-27234" target="_blank">significant challenges</a> for the management of the electricity system as a whole.
Unlike other industries where goods can be warehoused or stockpiled to manage fluctuations in supply and demand, electricity is not yet readily storable. Storage options such as batteries are now <a href="https://theconversation.com/the-tesla-battery-heralds-the-beginning-of-the-end-for-fossil-fuels-41197" target="_blank">commercially available</a>, but haven’t yet reached widespread use. This means that a system operator is required to keep the grid balanced in real time, ideally with just the right amount of capacity and backup to manage shocks in supply or demand.
Securing the right amount of generation capacity for the electricity grid relies on long-term planning, informed by accurate supply and demand forecasts. Too much investment means excessive prices or assets lying idle (or both). Too little means longer, deeper or more frequent blackouts.
But as solar panels spread rapidly through the suburbs, the job of forecasting supply and demand is getting much harder.
This is because the commercial history of residential rooftop PV has been too short, and the pace of change too fast, for a clear uptake trend to be established. Previous attempts to predict the market’s continuing growth have thus entailed a lot of guesswork.
<h2>Why do people buy solar panels?</h2>
One way to improve our understanding is to talk to consumers directly about their purchasing intentions and decisions. The trick is to find out what prompts householders to take that final step from considering investing in solar panels, to actually buying them.
This was the approach we took with our research, <a href="https://www.sciencedirect.com/science/article/pii/S1364032118303769" target="_blank">published today in the international journal, Renewable and Sustainable Energy Reviews</a>. We analysed data from a survey of more than 8,000 Queensland households in 2014 and 2015, part of a <a href="https://www.ergon.com.au/network/manage-your-energy/queensland-household-energy-survey" target="_blank">survey series</a> commissioned by an industry group now known as <a href="https://www.energyq.com.au/" target="_blank">Energy Queensland</a>.
<a href="https://images.theconversation.com/files/221437/original/file-20180603-142102-18m0kdj.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=1000&amp;fit=clip"><img src="https://images.theconversation.com/files/221437/original/file-20180603-142102-18m0kdj.png?ixlib=rb-1.1.0&amp;q=45&amp;auto=format&amp;w=754&amp;fit=clip" alt=""></a>
Comparison of motivational factors between surveyed PV intenders and adopters. Bondio, Shahnazari &amp; McHugh (2018).
We found that the decision to go solar was driven largely by housholds’ concerns over rising electricity bills and the influence that economic life events have over perceptions of affordability.
But the households that tended to adopt PV were also those that were affluent enough not to be put off by the relatively large upfront cost.
This combination of having access to funds, while at the same time being concerned about future electricity prices, appears to be a broadly middle-class trait.
While the upfront cost of PV can deter lower-income households, this can be overcome by receiving an offer that is too good to refuse, or if concerns about ongoing electricity bills are acute – particularly in the case of retirees.
Electricity price uncertainty is a particular concern for retirees, who typically have a lower income. We found that retirees were more likely than non-retirees to invest in solar panels, all else being equal. Retirees, like many people who invest in solar power, seem to view buying solar panels as being like entering into a long-term contract for electricity supply, in that it provides price certainty over the life of the PV system.
We also found that while the idea of self-sufficiency was important for developing an intention to buy solar panels, this motivation later fell away among households that went ahead and bought them. This could be because householders who buy solar panels, but find themselves still relying significantly on the grid, may conclude that self-sufficiency isn’t achievable after all.
About one-third of those who said they intended to buy solar panels cited environmental concerns as a reason for their interest. Yet this factor did not significantly increase the odds of them going on to adopt the technology. This suggests that when it comes to the crunch, household finances are often the crucial determining factor.
We also found the chances of adopting solar panels were highest for homes with three or four bedrooms. Smaller homes may face practical limitations regarding roof space, whereas homes with five bedrooms or more are likely to be more valuable, suggesting that these householders may sit above a wealth threshold beyond which they are unconcerned about electricity bills.
But perhaps our most important finding is that analysis of household survey data can be useful to forecasters. Knowing who is adopting rooftop PV – and why – should enable better predictions to be made about the technology’s continuing expansion, including the crucial question of when the market might reach its saturation point.

Are solar panels a middle-class purchase?

<html><body>
Landlords and tenants are set to both benefit financially with Sunyield, Stoddart Group's new solar technology.
A new batch of homes in Queensland, <a href="https://www.choicehomes.com.au/sunyield/" target="_blank">built by the likes of Choice Homes</a> and Brighton Homes, will see the solar panels save as much as $275 a year on electricity.
Stoddart Group's general manager for energy systems Adam Taylor says solar energy usage was once a difficult conversation with landlord and tenant before the new technology.
“It was too difficult to manage," he said.
“With SunYield, if the tenant chooses to use the solar panels, all solar and grid power is measured automatically via a smart switchboard and the tenant receives a single monthly power bill for all electricity consumed from both the solar and the grid.
“Renters have long missed out on the benefits of solar power simply because it was too hard or complicated for landlords to justify the cost.
“SunYield changes this by ensuring that solar on a new rental property is a good deal for the landlord, as well as the tenant.  
The process is completely automated, with the landlord then receiving a payment for all solar generated, whether it was used by the tenant or sent to the grid.
“With this technology, the landlord owns the solar system and can either sell the power to their tenant at a discount to the market rate or export it to the grid if the tenant chooses not to buy it.” 
The SunYield package includes a 6.5 KW solar power system, combined with a Stoddart Smart Board that replaces the standard meter box on a new home.  
SunYield is also battery ready, allowing landlords to add batteries as they become cheaper and increase the proportion of solar-generated power sold to the tenant.
Choices Homes director Troy Knight said the innovative technology is good for his customers, their tenants and the environment.
“We're always looking for ways to offer our customers a better investment, which made the decision to put SunYield on every home a simple one," he said.
“For our customers, it means an increased rental return and a home that's easier to rent. 
"For our company, it means being one of the first to offer an innovative product that is good for our customers, their tenants and the environment.  
The Australian-first technology was designed locally and is being launched in Queensland with leading investment builders Choice Homes, Creation Homes, Brighton Homes and MetInvest, with each including SunYield as standard on their new homes. 
Stoddart Group will soon extend the solution to other builders and plans to install 15,000 SunYield systems over the next 3 years and Taylor believes the technology will quickly become standard on all new investment properties. 
“In the next 2 -3 years, we’ll see a complete shift - from rarely seeing a rental property with solar to it being difficult to find a new one without it," he said. 
Taylor said they did not have plans to release the product to the established homes market due to the way the technology works.
Stoddart Group partnered with leading energy provider, Powershop and technology company, Reposit to develop the solution and make it a seamless experience for the landlord, tenant and homebuilder.
Powershop boss Ed McManus said giving renters the ability to use solar power is positive for their power bills and the energy market.
“Powershop is always pursuing ideas that can help Australians get in control of their power bills. This program not only helps customers save money, but it also lowers their environmental footprint and puts more renewable energy into the grid. 
Reposit Power CEO Dean Spaccavento said the solar and battery industry is booming in Australia, but there have been technological barriers preventing investors and renters from benefiting.
"We can now do things with electricity that only a few years ago were ideas on paper," Mr Spaccavento said. 
"With smart technology like SunYield coupled with Reposit, we all now have a say in how our electricity is generated and what we pay for it.
"It's now possible for renters and landlords alike to benefit from rooftop solar. Landlords earn a profit and renters benefit from lower energy bills.
"SunYield is an investment now that will continue to improve and deliver results well into the future."

Tenants and landlords to benefit financially from new solar technology

<html><body>
Tenants moving into Queensland’s newest rental homes can expect to save around $275 a year on electricity, with Stoddart Group releasing Australia’s first landlord and tenant friendly solar solution, SunYield. 
The SunYield package includes a 6.5 KW solar power system, as well being battery ready.
The battery allows landlords to add batteries as they become cheaper, and increase the proportion of solar-generated power sold to the tenant.
It combines with a Stoddart Smart Board that replaces the standard meter box on a new home.
Tenants get a <a href="https://www.choicehomes.com.au/sunyield/" target="_blank">30 percent discounted rate</a> on power used generated by the panels, while landlords can generate an <a href="https://www.choicehomes.com.au/sunyield/" target="_blank">extra $25 a week of income.</a>
Stoddart Group’s general manager for energy systems Adam Taylor says tenanted properties have been ignored in the recent solar revolution.
“Renters have long missed out on the benefits of solar power simply because it was too hard or complicated for landlords to justify the cost,:" Taylor said.
“SunYield changes this by ensuring that solar on a new rental property is a good deal for the landlord, as well as the tenant.

Queensland's newest rental homes to save money with solar solution

<html><body>
Nearmap, the Aussie aerial imagery company, has paired its high-res imagery with the latest Clean Energy Regulator data, revealing the postcodes around the country with the highest rooftop solar uptake since 2001.  Queensland showed why its called the ‘Sunshine State’ taking out seven of the top ten postcodes.
Western Australia claimed the remaining three spots. 
Postcode 4670 in South East Queensland topped the list with 11,756 homes installed with solar units, closely followed by 6210 in Western Australia, just south of Perth, with 11,409 units installed since 2001.
“From the ground it can be difficult to see the progress our country is making to reduce energy costs and our carbon footprint,” said Nearmap executive, Shane Preston, “but when you look at it from the air, you can observe in incredible detail the renewable energy uptake occurring across our country. 
"We’ve been capturing aerial images of Australia for the last 10 years, and have recently seen a dramatic change in the rooftop landscape, with many more solar panels on Aussie homes.” “However, this is just the beginning. As the benefits of renewable energies like solar continue to surface, we can expect to see more demand for installations. For businesses, having access to <a href="https://www.nearmap.com.au" target="_blank">Nearmap’s</a> high-res aerial images will become increasingly important.
"Using this imagery, solar companies can remotely identify new business opportunities, accurately estimate the power output and quote customers, all without leaving the office. 
"The ability to do all this remotely means businesses can not only save time, but can further contribute to reducing the carbon footprint by taking hundreds, if not thousands of cars off the road every year.”

While there are now more solar panels in Australia than people, the many Australians who live in apartments have largely been locked out of this solar revolution by a minefield of red tape and potentially uninformed strata committees.
In the face of these challenges, Stucco, a small co-operative housing block in Sydney, embarked on a mission to take back the power. Hopefully their experiences can serve as a guide to how other apartment-dwellers can more readily go solar.
From an energy perspective, Stucco was a typical apartment block: each of its eight units had its own connection to the grid and was free to choose its own retailer, but was severely impeded from choosing to supply itself with on-site renewable energy.
Things changed in late 2015 when the co-op was awarded an Innovation Grant from the City of Sydney with a view to becoming the first apartment block in Australia to be equipped with solar and batteries.
A central part of Stucco’s plan was to share the locally produced renewable energy by converting the building into an “embedded network”, whereby the building has a single grid connection and manages the metering and billing of units internally.
Such a conversion seemed like an ideal solution for solar on apartments, but turned into an ideological battle with the electricity regulator that took months and hundreds of hours of pro bono legal support to resolve.
In this way the Stucco project grew to embody the struggle at the heart of the Australian electricity market: a battle between choice and control, between current regulations that mandate consumers to choose between incumbent retailers, and the public’s aspirations for green self-sufficiency.

A chicken and egg problem
Embedded networks have been around for decades. Yet if the Australian Energy Regulator had its way, they would be banned as soon as possible.
The reason for this is that they inhibit consumers’ choice of retailer: consumers are forced to buy their electricity from the building’s embedded network management company, which may exploit its monopoly power.
Yet it doesn’t have to be this way. At least one company in Germany allows apartment residents to buy power either from their preferred grid retailer or from the building’s solar-powered embedded network. This business model relies on Germany’s smart meter standards that ensure all market participants can access the data they require.
We currently find ourselves in a standoff. The regulator is waiting on companies to offer solar powered embedded networks that include retail competition, while companies are waiting on the regulator to create an accessible playing field that would make such services viable.
The recently released Finkel Report touches on this by recommending a “review of the regulation of individual power systems and microgrids”.
Stucco’s bespoke solution
In the absence of such a solution, Stucco made a unique agreement with the regulator: the co-op committed to cover fully the costs of installing a grid meter for any unit whose occupant wishes to exit the embedded network in the future.
Such a commitment was feasible because Stucco’s residents, as co-op members, have direct input into the management of the network including controlling prices (that are mandated to be cheaper than any grid offer). But it is difficult to image regular strata committees accepting such liabilities.
Embedded networks are therefore not the best general solution for retrofitting solar on apartments, at least not under current regulations. This is unfortunate because they represent the best utilisation of an apartment block’s solar resource (Stucco’s system provides more than 75% of the building’s electricity) and are therefore increasingly being adopted by developers.
Advice for apartments

The good news for residents of existing apartments is that there are easier routes to installing solar. The even better news is that the cost of solar systems has plummeted (and continues to do so), while retail rates continue to skyrocket, so much so that body corporates are reporting rates of return of 15-20% on their solar investments.
The recommended options for apartments are epitomised by the old adage “keep it simple”. They fall into two categories: a single solar system to power the common area, or multiple smaller systems powering individual units. Which of these is best suited to a particular apartment depends primarily on the building’s size (as a proxy for its energy demand).
For buildings with 1 square metre of sunny roof space per 2m² of floor space (typically blocks up three stories high), it is worth installing a solar system for each unit, as these will typically be well matched to unit’s consumption.
Taller buildings (with less sunshine per apartment) are better off installing a single system for the common area, particularly if this contains power-hungry elements such as elevators or heating and cooling systems.
<a href="https://www.propertyobserver.com.au/images/2017/06/22/Screen%20Shot%202017-06-22%20at%2012.44.55%20PM.png" target="_blank">Click to enlarge</a>

But here’s the crux: no apartment can install solar without the political support of its strata committee. While this hurdle has historically tripped up many initiatives, increased public awareness has created a groundswell of support. Plus you may need fewer votes than you think.
While this article focuses on solar, it is important to remember that the first priority for any building should be to improve energy efficiency, by installing items such as LED lights, modern appliances, and insulation and draft proofing. For advice on these opportunities see the City of Sydney’s Smart Green Apartments website and the Smart Blocks website.
Lastly, adding batteries to an apartment solar system creates extra challenges, for instance fire-prevention planning. But it allows for far greater energy independence and resilience, and a chance to join the future of distributed energy currently being enjoyed by so many of Australia’s non-strata householders.

Get in on the ground floor: how apartments can join the solar boom

<html><body>
GUEST OBSERVER
This year many Australian households will find themselves cut off from generous incentives paid for electricity they export into the grid from rooftop solar systems. 
Between September and December, state feed-in tariff (FiT) schemes in New South Wales, Victoria and South Australia will finish.
The FiTs applying to over 275,000 customers will drop from between 16 and 60 cents per kilowatt hour to between 5 and 7.2 cents per kWh.
In NSW, the replacement FiT won’t be mandatory, with retailers allowed to decide what they pay. Of course, many of those customers have already recouped their investment. 
Now that our rooftop solar industry has matured, we need to reconsider the purpose of FiTs and align them with our goals for the electricity system in the future.
<h2>Why pay solar households?</h2>
FiTs have been hugely important in getting the global solar industry to where it is now. Solar electricity costs have fallen to levels that were unimaginable just 10 years ago.
Governments have traditionally used FiTs to achieve a policy aim, such as increasing renewable energy production by bridging the gap between current costs of electricity and the cost of new sources. 
Australian states began to introduce mandated FiTs in 2008. There has never been a national FiT in Australia, and Queensland, NSW and the ACT no longer have mandated FiTs. However, many electricity retailers offer FiTs, even when not mandated by government. 
<a href="/images/2016/12/09/image-20161107-27908-bq13sc.png" target="_blank">Click to enlarge</a>
<h4><img src="/images/2016/12/09/image-20161107-27908-bq13sc.png" alt=""></h4>
<h4>Current state of feed-in tariffs in Australia for new customers. Authors</h4>
The costs of FiTs are recovered in different ways, depending on whether they are government-mandated or not, but ultimately they fall on all electricity consumers. As governments wind back mandated FiTs, it’s assumed that FiTs will be roughly cost-neutral. 
<h2>Have they worked?</h2>
Residential solar installations soared after the introduction of FiTs in 2008.
Installations quadrupled each year in Australia until 2012, leading to 11,600 jobs and the highest penetration of households with rooftop solar in the world.  
This boom stimulated a competitive solar market in which residential installation costs have plummeted (as you can see below).
Australia now enjoys some of the lowest installation costs for rooftop solar in the world.
The trick that state policymakers missed, however, was making FiT policies sustainable. 
Early FiTs were excessively high, especially in NSW and Queensland, causing policy fallout and sudden withdrawal.
This was partly because the rapid reduction in solar prices exceeded expectations.
For example, the NSW government was forced into a hasty reassessment of its 2010 policy in order to prevent a cost blowout after massively underestimating the level of uptake.
By October 2010, just 10 months after it began, the NSW gross FiT was slashed from 60 to 20 cents per kWh. The scheme was closed to new participants in April 2011. 
Across Australia most states cut or entirely removed FiTs within four years. Most current FiTs are now well below retail prices.
This means that customers are being encouraged to use as much as possible of their solar energy to power their own homes rather than exporting it to the grid.
This is one of the reasons why the system size for solar installations in Australia tends to be smaller than elsewhere.
The fallout from these unsustainable FiT policies has unfortunately polarised the national conversation about solar.
Hundreds of thousands of solar power system owners are facing bill shock as FiTs are withdrawn, while those who do not have solar have been told they are footing the bill for their neighbours’ systems.
Politicians have sought to capitalise on this discontent, by blaming solar tariffs for high electricity prices. In many states, the actual value of rooftop solar has been pushed out of the conversation.
<h2>The real value of solar</h2>
A recent Victorian report found that the value of solar energy depends on when electricity is fed into the grid.
Solar energy is more valuable when exported to the grid at times of peak demand. 
The report argued that the value of solar should account for the reduction in transmission losses (the losses associated with transporting electricity from large power plants over great distances) and environmental effects, primarily the reduction in greenhouse gases from displacing fossil fuel generation. 
Solar installations can potentially add value in other ways too. For example, installing battery storage along with solar systems may allow domestic solar systems to offer other network services such as frequency and voltage control. 
Encouragingly, since the report the Victorian government has bucked the national trend and announced a multi-rate FiT scheme. 
The scheme offers different rates for exporting during peak, shoulder and off-peak times.
It will also reward solar owners for the greenhouse gas offsets related to their system’s output.
The scheme is expected to raise FiTs from around 5c per kWh to an average of between 6.5c and 7c per kWh. 
<h2>What next?</h2>
Nationally, we need to refocus the conversation about the purpose and value of FiTs.
Having already established a world-leading solar industry, we need to ask what FiTs can do for us now and into the future. 
If we want our electricity system to take advantage of technological advances, such as battery storage, we need to repurpose our FiTs to reflect the benefits of these technologies.
The Victorian example is a great step forward, providing a mechanism where consumers can leverage Australia’s low installation costs to become players in a more competitive energy market. 
But there are even more benefits to distributed energy systems that could be realised with intelligently applied FiTs.
This means we need more consideration of what solar systems can do for us, and less simplistic conversations about electricity costs.

GUEST OBSERVER
Winter is here! Despite many Australians opting not to heat their homes to the point of complete comfort, many of us nevertheless will soon receive a nasty surprise when the energy bills arrive.
With Australia’s historically cheap energy, old housing stock in many areas, mild climate and frequent emphasis on low building costs, many homes are little more than “glorified tents” when it comes to thermal performance.
Besides wanting smaller bills, many residents also want to improve comfort, lessen their environmental impact and boost their home’s value.
So here is a list of 22 things you can do to improve your home’s energy performance – some cheap, some free, and some that can even make you some money up-front as well as cutting your bills. Of course, to reach the ultimate goal of a home heated and powered by 100 percent renewable electricity you may still wish to put some solar panels on your roof, but why not consider the following actions first?
1. Make sure you get the maximum discount on your energy bills. Although not available everywhere, in Victoria discounts of up to 38% are available on gas or electricity. Ring up your retailer and just ask, or threaten to switch, or better yet seek out a retailer that doesn’t treat their discounts like state secrets.
2. Monitor your power usage with the help of a “smart” electricity meter or in-home electricity display. This real-time (or near-real-time) information is more useful than the coarse monthly data commonly printed on energy bills. It can help identify appliances that have inadvertently been left on or those that draw excessive power when not in use.
3. Heat your water off-peak. If you have a resistive-electric hot water storage tank, make sure it heats up at night, when off-peak power rates apply. In some areas, “time of use” rates are available.
4. Get rid of your ‘garage fridge’. It can cost hundreds of dollars a year to run an inefficient 20-year-old fridge, especially if it’s in a garage that hits 50℃ in summer.
5. Ditch your super-hot plasma. If you have a 10-year-old television that gets so hot you can fry an egg on the screen, check out the newer models that can use one-tenth of the electricity.
6. Install a modern showerhead, such as those designed with double-impinging jet technology that use only 5 litres of water per minute. Old showerheads can pass up to 35 litres per minute. Why not grab a bucket and stopwatch and test yours?
7. Insulate any exposed hot water pipes, including the pressure-relief valve on your hot water tank. Make sure hot water pipes do not run uninsulated straight into the soil in your garden. Insulate electrically heated storage tanks where it is safe to do so.
8. Check your heaters and air conditioning. Gas heating systems should be checked at least every two years by a qualified person, not least to keep poisonous carbon monoxide gas at bay. All heating or cooling system filters should be cleaned regularly to improve energy efficiency and air quality.
9. Inspect your ducts. Poorly installed or degraded ductwork can lead to big energy losses, which can go unnoticed for decades. Ensure that small children or animals have not gone under your house and damaged your gas heating ducts. Check also that air returns are properly “boxed-in” and do not draw air in from the wall cavity instead of from the living space. However, cleaning the inside of your ducts is not critical for energy saving, and risks damaging them in the process.
10. Banish drafts, for instance by plastering over those ubiquitous wall vents – relics from the days when homes relied on unflued heaters or gas lights. Seal off unused chimneys and fill any other cracks, gaps or holes around doors, windows, skirting boards, floorboards and architraves. Remember to close air-conditioning ceiling vents in winter. Ventilation should be controlled by opening windows, not by having permanent holes in the walls.
11. Eliminate ceiling-mounted downlights wherever possible. A small number of modern wide-beam LEDs can adequately replace a larger quantity of narrow-beam halogen downlights. Aim to have as few holes cut into your ceiling as possible, because these holes let heat escape in winter and let it in during summer.
12. Install downlight covers over all downlights that protrude into accessible attic spaces. Not only does this reduce fire hazards and keep out insects, but it will also reduce air flow through the roof.
13. Replace all regularly used lights with LEDs. LEDs use a tenth of the energy of halogen or incandescent bulbs, so will pay for themselves in just a few months (even less in places where free replacement is on offer). Replace less regularly used bulbs with LEDs as and when they burn out, and vow never to buy a non-LED bulb again.
14. Insulate your attic…. If you don’t have roof insulation, buy some. If you do, check it meets the recommended “R value” for your climate. Ensure all vertical attic surfaces (walls, skylight tunnels) are also insulated, and include a layer of aluminium in your attic space. Thermal imagingcan be used to identify existing flaws, such as gaps or sections of insulation inadvertently moved by tradespeople working in the attic.
15. …and your floors and walls too. In cooler Australian climate zones, floor and wall insulation can help keep heat in, making your home warmer and cheaper to operate.
16. Cover your windows from the inside… with drapes, curtains or blinds. This will keep in heat at night and on cold winter days, and keep out the sun in summer. Cheaper or do-it-yourself thermal window treatments such as plastic films or even bubble wrap can be applied in some situations (just don’t expect to win any design awards).
17. …and the outside. Trees, plants, external awnings, blinds or shade sails can all keep out the summer sun and stop windows getting hot. Remember that significant heat will reflect onto windows from sizzling decks, paved areas and walls (but not lawns). It’s better to keep out the sun in the first place rather than try to cool your house down.
18. Double glazing for windows cuts out noise, improves security and saves energy too. For many Australian climate zones, I recommend that homeowners never buy a window in future that isn’t double-glazed. Retrofit options options such as “secondary glazing” are also available.
19. Fit a pool cover if you have a swimming pool. Not only will this stop the water cooling down overnight in summer, but a cover can also minimise cleaning, chemical use and the running time for your filter pump. Consider upgrading to a more efficient pump if yours is more than a decade old, and ensure it does not run for more hours each day than required. 
20. Use reverse-cycle to heat your home…. If your home has reverse-cycle air conditioning (also known as a heat pump), this may be the cheapest way to heat, especially as gas prices rise. On heat mode, reverse-cycle units harvest free renewable ambient heat from the air outside your home and pump it up to the toasty temperature you need inside. Having installed high-efficiency reverse-cycle units, I can heat my own home for one-third of the cost of ducted gas heating.
21. …and your water. If your hot water system is nearing its use-by date, consider replacing it with a heat pump. This is an especially good option for homes that already have solar panels and low feed-in tariffs.
22. If you can eliminate all gas use in your home (for space heating, water heating and cooking), you can eliminate your gas bill with its nearly A$1 per day fixed supply charges.
<h2>And then there is solar…</h2>
In Australia these days, you won’t be paid much money for selling your electricity back to the grid. However, it might still pay to install solar if you can consume most of the energy yourself, by running your pool pumps, appliances, space heating and cooling devices, hot water system and even an electric car with solar electricity harvested during the day.
In future, as electricity storage batteries get cheaper, there may be even more economic reasons to have solar panels on your roof.
This article doesn’t list every possible behavioural trick or home improvement. Sadly, some homes will never be fantastic energy performers without significant modification. But hopefully there are a few things on this list that will work for you – even if it’s only a case of finally covering that drafty doorstep, or giving your creaking “beer fridge” a dignified retirement.
