GoodWe releases new residential all-in-one storage solution
The Chinese company says that its new ESA series is available with a hybrid inverter ranging from 3 kW to 10 kW and storage capacities of 5 kWh to 48 kWh. The IP66-rated product supports an MPPT current of up to 20 A on the PV side and allows 200% PV oversizing, according to the manufacturer.
How Pacific nations plan to go from spending up to 25% of GDP on fossil fuels to running on 100% renewables
Picture dusk falling somewhere in the Solomon Islands. A fisher’s skiff glides home using a whisper-quiet electric outboard motor. In the Cook Islands, a big battery steadies the island grid. In Papua New Guinea’s highlands, solar kits bring electric light to homes for the first time.
NSW energy distributors de-risk transition with new, unified system plan
Three New South Wales energy distributors have collaborated on the state’s first distribution system plan, which they say can sustain five years of energy transition momentum, while waiting for critical transmission infrastructure to be built.
Three hours of free power sounds great – but it could raise other costs and hamstring rooftop solar
It was the news that rippled around the nation – and then the world: at least three hours of free grid-supplied electricity for Australian households, every day.
Heritage building solar, battery installation red tape slashed in NSW
The New South Wales state government has slashed red rape for owners of state heritage-listed properties who can now install solar panels and batteries without seeking formal approval.
Optimising PV system tilt angle, MPPT using fuzzy logic controller
Researchers in the Middle East have developed a fuzzy logic controller that simultaneously optimises the tilt angle of PV systems and performs maximum power point tracking. Year-long simulations indicate that the proposed approach increases power generation by approximately 20%.
Utility batteries draw short straw in Solar Sharer scheme: Rystad analysis
Rystad Energy has released analysis of the federal government’s Solar Sharer scheme saying forecast increased demand from utility and household batteries and a slowdown of rooftop solar could boost utility renewables and coal via increased daytime demand, but impact gas and utility batteries.
Japanese companies partner to establish solar glass recycling scheme
Two Japanese companies have announced a partnership to advance the recycling of solar panel cover glass for application in architectural flat glass production.
Japanese utility uses Sharp PV-linked home batteries for grid balancing
Japanese utility Tohoku Electric Power is using Sharp’s residential batteries and AI-powered energy management systems to balance grid demand and optimise household solar energy use. Customers in the program can earn points redeemable for local products.
Solar cell inspection tool evolution set to slash manufacturing costs by billions
Researchers at the University of New South Wales in Sydney are working with the institution’s spinout company BT Imaging to accelerate the commercialisation of solar cell defect detection technology, thanks to a $1.4 million commercialisation project.
