GE Vernova releases 2,000 V (DC) utility-scale inverter
GE Vernova has developed a 2,000 V (DC) utility-scale inverter, to be used in a North American pilot operation starting in early 2025. The inverter offers up to 6.0 MVA of output power.
World now has five times more PV than nuclear power
According to the World Nuclear Industry Status Report 2024, the world had 408 operational reactors producing 367 GW in the middle of the year, which is significantly less than installed capacity predictions for solar by the end of the year and five time less the world’s cumulative PV capacity.
Sharp launches 450 W bifacial TOPCon module with 22.52% efficiency
Sharp’s new IEC61215- and IEC61730-certified solar panels have an operating temperature coefficient of -0.29% per C and a bifaciality factor of over 80%.
New refrigerant may improve coefficient of performance of air-source heat pumps by up to 21%
Developed by a Chinese research group, the novel refrigerant is made of a mixture of carbon dioxide (CO2) and a non-flammable hydrofluoroolefin. It has slightly higher costs compared to conventional compounds, but its creators claims these costs could be significantly reduced with large-scale industrial production.
Silfab launches 640 W utility-scale solar panels
The Canada-based manufacturer said its new panels have a temperature coefficient of -0.29% per C and an efficiency of up to 22.92%. They come with a 30-year power output guarantee for 89.3% of the initial yield.
Generac presents new residential batteries
The U.S.-based storage system providers said its new batteries are configurable in 3 kWh modular increments up to 4 cabinets per site. Their roundtrip efficiency ranges from 88% to 91%.
Solis launches 60 kW and 125 kW string inverters
Solis has developed new 125 kW and 60 kW string inverters for the U.S. and Canadian markets, both with a maximum efficiency of at least 98.5%
Startup offers AI-based software solution to predict component failure in utility-scale inverters
Infinrel says its Energy Kardio Graph solution can sample small electrical perturbations on the input and output of the inverter at MHz scale and enable insight into the actual operation of the inverter on its switching cycle basis.
U.S. authorities detain solar modules imported from Mexico
Module manufacturer Maxeon says that U.S. Customs and Border Protection officials have detained all of its panel imports from Mexico since July as the federal law enforcement agency investigates their compliance with the Uyghur Forced Labor Prevention Act (UFLPA).
Quantum algorithm for photovoltaic maximum power point tracking
Researchers have developed a quantum particle swarm optimization algorithm for maximum power point tracking that reportedly generates 3.33% more power in higher temperature tests and 0.89% more power in partial shading tests compared to conventional swarm optimization algorithms.
