A guide to help homeowners understand how to go solar
Researchers at Pacific Northwest National Laboratory published an open access guide to rooftop solar and battery energy storage that covers costs, incentives, policies and more.
New quantum solar cell material promises external quantum efficiency of 190%
The new material consists of an heterostructure combining germanium, selenium, and tin sulfide, which also integrates atoms of zerovalent copper. It features an average photovoltaic absorption over 80% and could help photovoltaic cells break the Shockley-Queisser efficiency limit, according to its creators.
S-5! unveils new mounting systems for rooftop solar
S-5!, a supplier of mounting systems, plans to release two new mounting components for rooftop PV systems, including a new mount that allows for module-level power electronics to be attached directly to solar panel frames.
Renewables and storage interconnection backlog grew about 30% last year
The wait for transmission interconnection studies constitutes a “major bottleneck” for solar, storage and wind projects, which accounted for over 95% of all active capacity awaiting studies at the end of 2023, Lawrence Berkeley National Laboratory has reported.
