Selected projects will be awarded a fixed tariff of ILS 0.2091 ($0.06.708)/kWh over a 23-year period.

The device has a 4-in-1 design, which means it can be connected with four solar panels with a power output of up to 625 W each, through four independent connections. The output of each panel is tracked and converted individually. According to the Chinese manufacturer, the micro-inverter can ensure savings of up to 50% due to the lower number of devices and cables needed.

The new heterojunction module series is compatible with Panasonic’s Evervolt battery and has a power output ranging from 400 to 410 W. It also features a temperature coefficient of -0.26% per degree Celsius.

The research institute has upgraded its REopt web tool to include ground-source heat pump technologies. US homeowners will now be able to simulate the impact of converting conventional heating and cooling systems to geothermal heat pumps.

Cornell Researchers have found that upstate New Yorkers prefer rooftop solar to community solar under 50 acres, but opinions are split 50/50 over large-scale ground mounts. The distaste for utility-scale solar is strongest when converting forests, public land and productive farmland.

Developed by a Canadian start-up, Solar Ink can be used to create standalone perovskite solar modules or it can be combined with existing solar modules in a tandem configuration. It can be coated on both flexible and rigid substrates, resulting in translucent solar cells which, in turn, can be used to produce flexible and light modules for application in solar windows and vehicle-integrated photovoltaics.

Spanish researchers have developed a new modeling technique to assess the performance of semi-transparent PV systems for greenhouses. Their novel approach considers the broadband and spectral content of the irradiance, the solar cell technology and its performance metrics, and the relationship between the photosynthetic rate and the effective photon flux that falls on the crops.

Seraphim’s new solar modules are available in monofacial and bifacial variants. They rely on multi-busbar technology and are built with 210 mm silicon wafers.

Current price signals to distributed battery owners “do not align with grid value,” says a study from the Lawrence Berkeley Laboratory.

A solar panel on display at a science museum in the Netherlands is one of 2,748 modules that were used for the country’s oldest PV system. The module has an efficiency of around 9% and a power output of 18W. It was manufactured by Germany-based AEG-Telefunken in 1982.
