California rooftop solar installations drop 80% following new net metering rules
Over 17,000 layoffs have occurred, representing 22% of the industry. More job losses are expected.
EnerVenue offers pre-assembled nickel-hydrogen battery vessels
The stationary energy storage solution includes nickel-hydrogen batteries, the battery management system and cabling.
Photovoltaics for marine wildlife telemetry devices
A US research team has tested mini solar modules in marine data collection devices, using animal hosts for water column profile measurements. The findings suggest that submarine PV can effectively operate in these applications at depths of up to 22 meters.
Lobbyists call for more front-of-meter solar in California
California should put front-of-the-meter distributed solar on an equal footing with transmission-connected utility-scale solar and behind-the-meter solar, say several US advocacy groups.
Perovskite-silicon tandem solar cells provide extra protection against reverse-bias degradation
An international research team demonstrated that monolithic perovskite-silicon tandem cells do not suffer the same degree of reverse bias degradation that is typically seen in perovskite single junction solar cells under partial shading. They explained that the tandem devices are “protected” by the silicon subcell.
US EIA says solar power will surpass hydropower by 14% in 2024
Solar capacity has rapidly grown in the United States, while manufacturing costs have fallen, prompting the US Energy Information Administration (EIA) to predict that PV will generate 14% more electricity than hydroelectric facilities in 2024.
Infinite Turbine debuts heat pump turbine for homes, businesses
Infinite Turbine has developed a heat pump turbine for residential and commercial applications, using PV or alternative electricity sources for simultaneous cooling and hydraulic power. The tech can be retrofitted with existing CO2 heat pump systems for air conditioning, hot water, and process heat.
The Hydrogen Stream: Germany, Italy plan hydrogen pipeline to North Africa
Germany, in collaboration with Italy, has revealed plans to import hydrogen from Northern Africa.
Reconductor existing transmission to ‘unlock’ renewables, says UC Berkeley study
Large-scale reconductoring of existing transmission lines could cost-effectively double transmission capacity within existing rights-of-way, a study says. Renewable energy projects near reconductored transmission lines could more easily interconnect.
Soltec introduces hail defense algorithm for solar trackers
Hail losses in the United States exceeded $1 billion in 2021.
