Interested developers will have time until February 3 to submit their proposals.
Marstek debuts AC coupled residential batteries
The Chinese manufacturer said its new products have a capacity of up to 5.1 kWh and are scalable up to 20.48 kWh. The systems feature a depth of discharge of 90% and can purportedly operate for more than 6,000 cycles.
Panasonic offers residential heat pump solution that uses solar radiation forecasts
Panasonic has unveiled a new version of its Eco Cute CO2 heat pump that produces domestic hot water mostly during daytime based on solar radiation data. It integrates a dedicated app to obtain day-ahead solar forecasts and schedule water heating hours for the next day.
Fraunhofer ISE warns of risk from higher than expected UV-induced degradation in TOPCon, PERC, HJT cells
The researchers of the German institute explained that UV-induced degradation may cause larger than expected efficiency and voltage losses in all dominant cell technologies, including TOPCon devices. The scientists expect that silicon nitride layers could be used to enhance TOPCon UV stability compared to PECVD layers typically utilized in PERC and heterojunction cells.
