Residential solar panels are often sold with long-term loans or leases, with homeowners entering contracts of 20 years or more. But how long do panels last, and how resilient are they? Panel life depends on several factors, including climate, module type, and the racking system used, among others. While there isn’t a specific “end date” for a panel
Chinese solar module manufacturer Longi has revealed it achieved a power conversion efficiency of 34.85% for a two-terminal tandem perovskite solar cell. The U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) certified the result, which represents a world record for this cell typology. The previous record was held by Longi itself, which achieved a 34.6% efficiency for a device

Scientists tested bifacial PV devices based on silicon and gallium arsenide cells connected in a four terminal layout. They note that the four terminal design offers significant advantages over more common two terminal devices, allowing for a 17% (relative) increase in efficiency thanks to better absorption of light reaching the rear side.
