Residential PV

New South Wales home and business battery installation incentives are now available, in state government efforts to make the grid more reliable and stable and allow further reduction of reliance on fossil fuels during peak demand.

Solinteg has developed the IntegOne HSH, a residential solar storage system that combines a single-phase hybrid inverter with one or two batteries. Up to 10 systems can connect in parallel, offering a maximum efficiency of 97.6%.

The results of this year’s Kiwa PVEL scorecard have shown that TOPCon technology is more vulnerable than PERC, and the failure rate at bill of materials has increased to 41%, the highest in history, according to the testing lab.

The International Energy Agency’s latest report, which maps out the future evolution of clean energy manufacturing, says the combined global market for PV, wind turbines, electric cars, batteries, electrolysers, and heat pumps will rise from $1 trillion in 2023 to more than $3 trillion by 2035.

United States-based Bluetti has developed a new energy storage system that offers up to 154.8 kWh of storage and 60 kW of output by connecting up to three systems in parallel. It includes an inverter and a voltage controller with up to seven batteries.

Rooftop solar has outshone other renewables in Q3 2024, contributing 38.5% of generation ahead of grid-scale solar, 18.3% and wind,13.4%, while new capacity progressing through the connection phase grew 36% and battery projects, by 87%, compared to Q3 2023.

China-based inverter and battery manufacturer Sofar has identified an increasing shift in the Australian rooftop solar and residential energy storage market, predicting growing demand for fully integrated options.

Labelled the “most difficult” in the world, Australia’s regulatory environment and grid connection process for new large-scale renewable energy generation and storage has also been lauded as the standard bearer for the global market.

The Clean Energy Regulator’s decision to suspend online trading platform Greenbot from participating in the Australian government’s rooftop solar rebate scheme has been reinstated by the Federal Court.

While Australia continues to be a revelatory solar market internationally, it lost its place in the top 10 solar installers globally in 2023, the IEA PVPS team reports. According to Renate Egan, Executive Director for the Australian Centre for Advanced Photovoltaics, it is the first time in 30 years Australia has dropped off that list. “What’s sad is that the rest of the world is now taking off and investing in solar and we’re falling behind,” she said at Melbourne’s All Energy on Thursday.
