How to cut U.S. residential solar costs in half

Residential solar in the United States is experiencing a downturn. The industry has suffered major bankruptcies, lowered demand, and soon faces the loss of the 30% residential solar tax credit, among other challenges. And while rooftop residential solar is expected to soon get more expensive, Andrew Birch, co-founder and chief executive officer of OpenSolar, said it can be a lot cheaper

European initiative launches digital product passport prototype for PV

Researchers at the Bern University of Applied Sciences (BUAS), working in the EU-funded project “Retrieve project,” have developed a prototype of a digital product passport (DPP) to support circular practices in the European PV industry. The DPP-based platform aims to improve data management and traceability throughout the PV value chain, facilitating more effective end-of-life (EoL) management and circular economy

How to assess bifacial PV system performance on sloped terrains

Researchers from Bangladesh’s East West University have developed a novel method for analyzing bifacial PV systems on sloped terrains. The novel technique is a precursor formulation that is then inserted into existing PV simulation models that do not account for hilly solar farms. “A complete reformulation for bifacials would need a lot of effort, so instead we
