Power Roll testing new metrology for perovskite solar
The UK-based perovskite solar PV specialist has announced a new metrology research project with Swansea University and a new development agreement with Renolit, a German plastic films, sheets and polymer solutions company.
Korean scientists boost performance of tin monosulfide cells with new post-treatment
Researchers in South Korea improved the performance of tin monosulfide (SnS) solar cells with a potassium fluoride-assisted post-treatment and a vapor transport deposition process. The treated solar cells had a power conversion efficiency of 4.10% and reduced recombination sites, compared to 3.42% for untreated devices.
A closer look at Tesla’s new residential solar panels
The new Tesla Solar Panel and mounting system pairs with the company’s inverter, Powerwall battery, EV charging and vehicles, creating an all-Tesla residential solar offering for the first time.
Sungrow brings grid-forming PowerTitan 3.0 storage system to Europe
Sungrow is introducing its large-scale energy storage system, PowerTitan 3.0, to Europe, featuring grid-forming capability, next-generation battery cells, DC coupling for co-located solar projects, and streamlined commissioning to accelerate deployment.
Samsung releases new all-in-one heat pump for residential use
The South Korean giant said its new EHS All-in-One provides air heating and cooling, floor heating, and hot water from a single outdoor unit. It can supply hot water up to 65 C in below-zero weather.
SolarEdge, Helioplant build 6.3 MW ‘cross-shaped’ bifacial PV system for Alpine regions
Helioplant will leverage SolarEdge’s inverter and power optimization technology to power its cross-shaped bifacial solar system specially designed for snowy Alpine regions with high elevation. They anticipate ski resorts will be a big market for the solution which uses SolarEdge’s technology to overcome shading issues caused by the cross-structure.
France’s largest rooftop solar project begins construction
The largest single-unit rooftop solar power plant in Europe, developed by French independent power producer Urbasolar, is under construction on the Delta 3 multimodal logistics platform in Dourges, in France’s Hauts-de-France region.
Testing fault at 100 MW battery disrupts Estonia-Finland power link
During testing at Estonia’s 100 MW Kiisa battery park, both EstLink 1 and EstLink 2 tripped, triggering the most severe disturbance to the regional power grid since desynchronization from the Russian electricity system. As a result, nearly 1 GW of capacity was lost within seconds. The park’s owner has since publicly pointed to the battery manufacturer.
Moonwatt brings DC-coupled, passively cooled sodium-ion tech to solar projects
The Dutch start-up, founded by former Tesla leaders, is taking a novel approach to sodium-ion battery technology, optimizing it for integration with solar power plants. Its technology is set to be deployed for the first time in a Dutch solar-plus-storage project later this year.
