Can rooftop solar on public housing bridge the energy divide?

New public housing properties may offer six-star energy efficiency and split-system air conditioners but rooftop solar that might allow tenants to use them without fear of bill shock is not part of the package.

While 100 per cent of the ACT’s electricity will be sourced from renewable sources from January this year and the ACT Government touts its leadership credentials on climate change, the Territory’s most vulnerable tenants may still not be able to afford to heat or cool their properties, despite access to energy rebates and energy-efficient appliances.

The public housing renewal program has seen the building of new low-rise developments, such as the one in Chapman.

Their rooftops seem perfect for photovoltaic systems that would do away with the need for low-income energy rebates and turn the properties into mini powerhouses feeding the grid.

In fact, the idea is canvassed in the ACT Sustainable Energy Policy 2020-25 Discussion Paper. The NSW Solar for Low Income Households Trial allows eligible concession cardholders to forgo their low-income household energy rebates in exchange for free installation of a 2.5 kW solar system.

Climate Change Minister and Greens leader Shane Rattenbury says the ACT Climate Change Strategy 2019-25 includes an action to investigate options for providing solar to public housing and extending the Solar for Low Income Program to those tenants.

At present, Housing ACT does not offer rooftop solar for suitable properties, although tenants can request to install and maintain systems at their own cost, and the Solar for Low Income Program is supporting a limited number of low-income households to do so.

During 2018-19, Housing ACT approved 15 such requests from tenants, who may be required at the discretion of Housing ACT to remove the solar power system and return the property to its original condition when they vacate the premises.

Housing ACT does not collect data on requests to remove systems.

Better Renting executive director Joel Dignam says that wherever practical, it would be great to see rooftop solar on new public housing.

“This would help people in public housing save money on their power bills, and for these people, these savings could make a big difference,” he said. “And more solar energy means less climate pollution from fossil fuels. The ACT Government is already showing leadership by improving the energy efficiency of public housing, and there’s potential to do more here.”

Solar

Analysis by St Vincent de Paul Society in its ACT Tariff Tracker Report 2018 found that a Canberra household with solar was around $1000 per year better off compared to a household powered by traditional energy sources.

Mr Dignam said Better Renting backed measures that may support people who rent, or others with unsuitable rooftops, to benefit from solar, including solar gardens, where community members can invest in an off-site solar installation and receive a credit on their electricity bill.

“We hope to see more initiatives like this so that no households are locked out of the benefits of solar,” he said.

At this stage he did not think private landlords should be required to install rooftop solar, although evidence showed it was a great investment for them to make.

“It improves the value of the property, it means your tenants want to stay longer and it reduces the risk of rental arrears. If you think it’s a good idea to invest in a rental property, it’s an even better idea to invest in solar,” he said.

Tenants Union Executive Officer Deb Pippen said rooftop solar would be a good step for Housing ACT to be a model landlord and provide something that ”talks the talk” about caring about energy efficiency and people who are disadvantaged.

But the ACT Council of Social Services is more cautious, saying in its response to the ACT Sustainable Energy Policy 2020-25 Discussion Paper that there were concerns about the NSW trial concept where rebates are foregone and it would want to see a series of case studies that demonstrated the idea’s feasibility and benefits before supporting such a proposal.

The government says Housing ACT manages a portfolio of over 11,700 properties in a mix of housing types, including multi-unit properties, and many may not be suitable for solar panels due to a range of conditions, including the age of the property, orientation and tree coverage.

It says Housing ACT works closely with government and industry stakeholders to provide information to public housing tenants about available rebates, energy savings and how to maximise energy efficiency in their homes. ActewAGL will host an information desk for tenants at the Housing ACT Gateway office in January and February.

Mr Rattenbury says the Greens believe that all Canberrans should have access to comfortable, efficient and affordable housing, and are working to improve the climate resilience and energy efficiency of ACT homes with a focus on rental properties, public housing and low-income households.

“We are committed to supporting the most vulnerable in our community for a just transition to net-zero emissions, where everyone can enjoy the benefits of improved energy efficiency and renewable electricity generation,” he said.

But the housing house I’m in has ZERO outdoor balcony hanging and supplied a 1 star dryer... 😕

Public housing tenants should not be entitled to free solar panels when ratepayers and property owners cannot afford them or have to take out large loans. Equity works both ways and giving benefits to welfare recipients that puts them ahead of others will undermine community support for public housing. Solar panels should be on all buildings.

Robyne Mitchell Robyne Mitchell 7:40 am 07 Jan 20

Right now here in Canberra, and I presume most other places in or near fire areas, that the solar panels are covered in fine ash, so they will not work very well. I wonder if they clean the solar farms near the Mugga tip or further down south on the Cooma road? The solar farm near Mugga tip must always be covered in dust impeding their efficiency.

    There are companies that do this. https://www.simssolar.com.au/solar-farms

Great to see white roofs. All houses should have pale roofs.

Capital Retro Capital Retro 9:54 am 06 Jan 20

As long as tenants pay an increased rental commensurate with the spread of capital cost I see no problem. Tenants should also wear the cost of annual maitenence on the appliances.

Veronika Sain Veronika Sain 9:37 am 06 Jan 20

That’s still incredibly better accomodation than most ACT residents could afford to rent or buy.

    PM Brown PM Brown 12:25 pm 06 Jan 20

    What's your point? That people in public housing don't have the right to live in decent accommodation?

    Veronika Sain Veronika Sain 12:29 pm 06 Jan 20

    I grew up in a government house. My point is it’s great accomodation and better than most people have. The addition of solar is nice but the price would be huge. Can you afford solar panels on your home?

    PM Brown PM Brown 11:41 am 07 Jan 20

    I watched parents raising their kids at Northbourne Flats, a 50 year old housing estate with public laundries that were frequented by junkies. If they didn't knock down that and other old Canberra public housing estates (and build new places with the money), those families would still be there. If you're okay with that, to be honest there really isn't much point debating with you.

    Veronika Sain Veronika Sain 11:58 am 07 Jan 20

    You’re jumping to stupid conclusions here. All I’m saying is that sure it might be nice but it’s an expense the people who pay taxes here can’t afford because solar panels still cost a bomb.

    Plus those houses are far better than most people will ever live in. I don’t know many elderly who can even afford to have air conditioners. So what’s your point exactly?

    PM Brown PM Brown 12:18 pm 07 Jan 20

Surely the most humane thing they could do is work on their properties to ensure the poor sods living in West facing properties can survive at a reasonable level of comfort. External window shading, ceiling fans and hot air extractor systems should be an economical minimum. Some may need air conditioning.

Mat Barber Mat Barber 9:15 am 06 Jan 20

All public carparks should have solar panels above them, provides shade for the cars and generates clean power, I really dont get why it's still not being done

Margaret Dudley Margaret Dudley 8:51 am 06 Jan 20

Why aren’t all new buildings required to have a 6 star energy rating. There is more private than public housing being built

    Andrew O'Brien Andrew O'Brien 10:15 am 06 Jan 20

    Margaret Dudley I think new homes do have 6*

    Lauryn Roberts Lauryn Roberts 6:26 pm 09 Jan 20

    Margaret Dudley still hot boxes. Very poor designs.

While the power grid is shut down can a households roof to solar cells be be used to directly power up the house

    John Garvey John Garvey 8:01 am 06 Jan 20

    There are different ways to set up your solar system, but yes, you can set it up to do that. Usually in conjunction with a battery system.

    Anthony Bortolotto Anthony Bortolotto 8:10 am 06 Jan 20

    Elik Kloczko no it cant in the ACT but can be in other states so it useless in a power outage

    Elik Kloczko Elik Kloczko 8:11 am 06 Jan 20

    A domestic battery system can cost may thousands of dollars. Is there a simple one switch solution that can added on the power board to divert the energy produced back into the home for daytime power

    Elik Kloczko Elik Kloczko 9:12 am 06 Jan 20

    Anthony Bortolotto thank you,

Peter Major Peter Major 7:41 am 06 Jan 20

Who is paying for it and compensating power companies for poles, transformers, and lines

After watching 2040 ACT public housing would be the perfect place to trial SolShare, peer to peer microgrids

Well they are not much use in this weather with the ash all over them or the low level of sunlight.

    John Dale John Dale 7:40 am 06 Jan 20

    Robyne Mitchell that’s right. A couple of days here and there obviously means it’d be a waste of time. 🤦🏻‍♂️

    Tracy Hancock Tracy Hancock 8:42 am 06 Jan 20

    Robyne Mitchell on Thursday in Batemans Bay, the smoke was significantly thicker than here in Canberra. Interestingly, the neighbours solar Christmas lights were still flashing brightly at 5am.

    Ashley Wright Ashley Wright 6:01 am 07 Jan 20

    Tracy Hancock solar will still work but not to the same extent.

    It also doesn’t like hot temperatures, when it gets too hot the panels loose efficiency even if it is a nice sunny day.

    Either way even if there are x number of days a year where it is down it is still well worth having.
