Residential PV

PV modules are being sold with ever longer warranties, but when modules underperform or fail, making claims on those warranties is rarely straightforward. So are the warranties worth the paper they’re written on? Where does this leave installers? And how can this liability be mitigated?

Australian electricity wires are awash with sunshine, such that network operators have threatened to up the drawbridge on further rooftop connections, while limiting rooftop PV exports to the grid. But data streams hold the key to unlocking surprising existing capacity, stabilising voltage, and living the Aussie dream.

An International Energy Agency report led up by Rolf Frischknecht from Treeze in Switzerland and under the joint project management of the University of New South Wales’ José Bilbao has measured the lifecycle emissions of both residential solar PV with battery storage and gas-generated grid electricity. The results are not particularly surprising, only the Morrison Government’s ongoing obduracy is.

230 Northern Territory businesses have already received their vouchers for Australia’s most generous energy storage subsidity, the NT’s Home and Business Battery Scheme. The scheme, which is still open for applications until November 30, offers grants of $6,00 to homeowners and business owners to install solar and battery storage, or complement an existing solar system with a battery.

Earlier this year, Singapore surpassed its 2020 target for 350 MW of installed PV, and has set itself a more ambitious goal of 2 GW for the coming decade. pv magazine recently spoke with Thomas Reindl, deputy CEO of the Solar Energy Research Institute of Singapore (SERIS) – and also the lead author of a 2020 update to the institute’s PV Roadmap for Singapore report – to catch up on the latest developments in the city-state’s PV market.

As Green Finance begins to be seen more and more as global best practice the energy transition can only accelerate. This week, two stories attest to the growing acceptance of green finance by major financial institutions – ANZ Bank has pledged to extricate itself from thermal coal by 2030 and pursue more sustainable policies and Mike Cannon-Brookes supported startup Brighte announces Australia’s first 100% green asset-backed securitisation, $190 million in debt financing for Australians looking to uptake solar and battery storage in their home.

A report by Finnish company Wärtsilä has estimated the potential impact if every dollar committed to a non-renewables energy sector recovery was instead funnelled to clean power.

As Australia’s home battery market begins to catch up to its install residential solar capacity the opportunity for large-scale virtual power plants is verging on reality. Indeed, Solar Service Group’s new Solar + Battery Members’ Plan could see Australia host the world’s largest virtual power plant next year.

Rooftop solar installation figures in Victoria have plunged dramatically in recent months but an easing of Covid-19 restrictions has provided a welcome boost for the state’s small-scale solar installers.

In an effort to glean insights into the cost efficiency of sustainable housing, the Western Australian government in conjunction with private partners this week launched an Affordability Experiment home.
