What developers are still getting wrong about battery risk
Insurers caution that key blind spots remain for energy storage developers going through the underwriting process.
Free digital tool streamlines layout planning for rooftop solar systems
SL Rack has launched SL Planner, a tool linked to Google Maps that analyzes roof surface area and automatically distributes the appropriate number of solar modules.
Carrier debuts residential heat pump for cold climates
The U.S. heating specialist said its new heat pump system can operate “reliably” at -30 C and achieve 100% heating capacity at -17 C, with full cooling capacity being achievable at 50 C.
GE Appliances unveils residential hybrid heat pump water heater
The U.S. manufacturer said its new heat pump water heater can provide up to 60% more hot water than standard electric water heaters. The system is available in 240 V and 120 V options and with a capacity ranging from 160 L to 190 L.

The French authorities have concluded a commercial and industrial (C&I) rooftop PV tender with an average price of €0.09753 ($0.1110)/kWh. The government allocated 191 MW of PV capacity in total.
Search4solar launches sale of secondhand solar modules
Search4solar, a solar panel trading platform based in the Netherlands, is urging developers, installers and governments to reuse second-life modules, with more than 100,000 used panels currently in stock.
Solavita launches 30-50 kW hybrid inverter series
Chinese inverter maker Solavita says its new hybrid inverter series offers high PV oversizing, multi-port battery integration, and grid-smart controls to meet growing demand for scalable solar-plus-storage in commercial and industrial (C&I), and large residential markets.
PV-powered fine sand solar geyser for domestic hot water
The system is described by its creators as a cost-effective solution for water heating by storing thermal energy in fine sand. Techno-economic analysis indicated the system is economically viable for domestic water heating applications, with an initial capital cost of $278 and an expected lifespan of 25 years.
Estimating potential-induced degradation in PV systems used for water pumping
Researchers in Spain have developed a new method to estimated potential-induced degradation (PID) in solar modules used in PV-driven water pumping systems. The proposed approach can detect PID from the open-circuit voltage measurement of the system’s PV module strings.
