Concentrating PV Solar Could Hit Mainstream with Insolight

By Ryan Austin Swiss company Insolight has created the most efficient concentrating photovoltaic solar panels (CPV), a technology that uses lenses to concentrate light onto small solar panels underneath, to date. After two years of research, its created a CPV panel that achieved 29% efficiency, verified by the Universidad Politécnica de Madrid. Today’s conventional rooftop…

New Fraunhofer Solar Cell Stringer Uses Adhesives For 2% Boost

By Charles W. Thurston An R&D team at Fraunhofer ISE has unveiled a new solar cell stringing machine that can boost cell performance 2% by using electrically conductive adhesives to fix solar cells to a foil substrate in a shingled pattern. The process reduces the number of manufacturing steps that soldering a connective ribbon would…

Record 29% Concentrating Solar Cell Aims At Low-Cost Manufacturing

By Charles W. Thurston A novel combination of high-grade spacecraft solar cell material and advanced light-concentrating lenses has yielded solar panels with a record 29% efficiency that may become available for general rooftop use by 2022. The crux in the commercialization of the planar optical micro-tracking technology will be cost-controlling manufacturing process, which is the…

A 5-Step Roadmap to Zero-Emissions Buildings in CA

By Pat Remick California has laid a strong foundation for energy efficiency in new buildings. Now the state needs to figure out how to help the entire building sector meet a carbon-neutral future by 2045. A new report offers a five-point path forward, addressing barriers that have held back progress toward clean energy homes and…..

New 29% efficient solar panel combines space-grade PV cells with concentrated glass cover

By Kelly Pickerel Swiss company Insolight has reached 29% efficiency for its unique solar panel, as verified by the Solar Energy Institute of the Universidad Politécnica de Madrid (IES-UPM). Its patented optical system concentrates light onto an array of tiny space-grade multi-junction PV cells. Compared to traditional non-concentrated PV modules with efficiencies around 19%, Insolight’s…

Yes, Electric Vehicles Work In Winter — Better Than Gas Cars!

By Nicolas Zart Electric vehicles (EV) and gas cars are not very efficient in cold weather. But while we’ve grown to blindly accept the limitations of traditional cars, EVs are still misrepresented, especially when it comes to cold weather. It’s time we nip that myth Read Full Article Here For more great articles: Clean Technica

Driving energy efficiency investment beyond 2020

By Clare Taylor With rising GDP, the European Union is once again at risk of missing the 2020 targets for energy efficiency, and yet more ambitious targets for 2030 lie ahead. Regulation, especially for energy efficiency in buildings, is already driving demand, according to the European Investment Bank, with commercial banks acting as aggregators. Peter…
