2018 has been a watershed year for Australia’s PV sector, with the surge to rooftop solar uptake making the country the residential-PV capital of the world. And there’s a considerable potential room for growth, a whopping 50 GW a new study has found.

Around 40 residential properties across the port city of Fremantle, Western Australia, will be able to trade solar power using a blockchain-enabled platform. The trial is even open for residents who do not have solar PV on their rooftops.

After around 1200 applications were lodged for the original 1500 packages in as little as two weeks, the Queensland government has introduced an additional 1000 battery grant packages to help households and small businesses cut their energy bills with the help of solar and storage.

The number of Australian homes with solar PV systems installed on their rooftops has passed a two million milestone, show Clean Energy Regulator data. With an average of six panels installed a minute, the uptake shows no signs of subsiding.

If maintained, Australia’s current rate of installs would deliver 78% renewables by 2030, find Green Energy Markets in its latest edition of RE Index. The 50% renewables target proposed by the the Federal Labor Party and several state Labor governments would thus deliver a sharp market decline, with installations falling to a third of recent rates and workforce shrinking by three quarters.

The second phase of the proposed 250 MW virtual power plant will see Tesla Powerwall batteries and solar panels installed on 1,000 South Australian households.

AGL has developed an energy trading platform, which is being tried among its customers in Victoria. The new trading system allows households to sell their excess solar power and save money or help others save on their electricity bills.

While the rooftop market segment might indicate smooth sailing, the debate over low cost suppliers and installers serving Australian homes and businesses continues to simmer just beneath the surface. And one name remains especially prominent in the discussion: Euro Solar.

Against the backdrop of a mature rooftop solar market and a booming commercial and industrial solar sector, Australia has a competitive but vibrant solar retailer and installation market. However, not all have prospered and a prominent player has exited the market.

Chinese module manufacturer Trina Solar has launched its “all-in-one“ kit in Australia targeting the rooftop solar segment. Its expectations of the Aussie market are high, as the company continues to pursue overseas expansion to ride out the China government policy shake-up.
