New research from Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) has shown that combining rooftop PV systems with battery storage and heat pumps can improve heat pump efficiency while reducing reliance on grid electricity.

Massachusetts Institute of Technology (MIT) researchers have developed a new organic cathode material with an energy density higher than most cobalt-based cathodes. It can charge–discharge in as little as six minutes. Automaker Lamborghini has licensed the patent for the technology.

Germany’s Fraunhofer Institute for Solar Energy Systems (Fraunhofer ISE) announced today that it had produced at 421 W perovskite-silicon tandem glass-glass module measures 1.68 m2.

Canada’s Solaires Enterprises says its indoor perovskite modules are suitable for powering a range of electronic devices, such as wireless keyboards, smart door locks, electronic shelf labels, and sensors.

Scientists in Switzerland used project-level data from BloombergNEF to analyze completion times of renewable energy projects across 48 countries. They have found that average commissioning times have increased over the past two decades for all clean energy technologies.

In partnership with utility Pacific Gas and Electric, the residential solar installer enrolled distributed batteries to serve the grid during times of peak demand.

Since early 2003, the United States has retired the same amount of fossil fueled electricity generation capacity as it has installed, even while the size of the economy has grown by two thirds.

The short-term impact of extreme weather, such as flooding, high winds, hail, wildfire and lightning, was minimal in most PV systems studied.

The software includes various tools to isolate downed or damaged lines, automate energy production and consumption regulation and troubleshoot unintentional loops.

Developed by a U.S.-Saudi research group, the novel technique employs two 45-degree inclined mirrors on the two sides of a PV module.
