Water-based zinc-ion battery for stationary energy storage
Salient Energy developed the water-based zinc-ion battery to have the same power, performance, and footprint as lithium-ion systems without the safety risk.
Waterproof all-aluminum solar carport from China
Developed by Chinese manufacturer Enerack, the carport can host all types and sizes of solar panels and relies on waterproof technology for rain protection.
France simplifies environmental permitting for solar up to 1 MW
The new measures are expected to accelerate solar deployment across the country.
Kenya defines net-metering rules for solar
Kenya’s new net-metering regulations will apply to PV systems up to 1 MW in size.
Solar-plus-storage for islands
Indonesian remote islands are increasingly resorting to solar-plus-storage to cover most of their electricity demand. According to new research from LUT University, combining PV with batteries may help islands to cover around 60% of demand with renewable energy.
Germany deployed 548 MW of PV in May
The cumulative capacity of all subsidized PV systems in Germany hit 59.3 GW at the end of May.
Solar-powered residential heating system based on storage heaters
Spanish heating specialist Elnur Gabarron offers a residential heating system that works with surplus solar power and storage heaters. The system can work as a backup solution, combined with existing conventional heating, or as a household’s main heating system, with minimal use of grid electricity.
Taiwan maintains FIT rates for rooftop PV
The Taiwanese authorities have decided not to reduce feed-in tariffs for PV, as initially planned, in order to support more solar deployment. The country added around 1.9 GW of new solar capacity last year.
Storing solar power via borehole thermal energy storage
A Chinese-Finnish research group has proposed the use of seasonal, soil-based thermal energy storage in combination with photovoltaics in residential districts. They have found that the hybrid concept could cover up to 58% of total heating demand.
California ruling simplifies grid-connection process for distributed solar, storage
The California Public Utilities Commission has introduced a new rule to streamline the interconnection process for distributed energy resources.
