California’s home batteries are replacing gas plants and saving hundreds of millions
The Brattle Group analyzed a gigawatt-hour virtual power plant test that may be the world’s largest as part of its review of California’s distributed peak-shaving program. Battery manufacturing has scaled into the terawatt-hours annually, a breathtaking pace that could soon support multi-day backup of electricity systems. For now, U.S. installations fall far short of what […]

Scaling perovskite tandems’ U.S. prospects
Three US manufacturers actively working to commercialize their respective perovskite-silicon tandem technologies make the case for tandem modules. CubicPV, Caelux and Swift Solar argue a commercial future for perovskites is inevitable, and they tell pv magazine the current policy environment could work in the technology’s favor. From the magazine Commercial deployment of perovskites has traditionally […]
How rooftop solar can complicate residential real estate transactions
Many homeowners assume leased or loaned solar systems will boost their home’s value, but outstanding loans often drag down equity instead. Navigating the complexities of the real estate landscape is already tricky; add in the wonky, technical nature of selling or buying a home with rooftop solar, and realtors and homeowners alike can find themselves […]
