Description
Astronergy Solar Panels 640W belong to the CHSM78N(DG)/F-BH bifacial family and are engineered for utility-grade yield. The 640W AStronergy solar module uses n-type TOPCon cells with an upgraded multi-busbar layout to collect more current with lower loss. The bifacial, dual-glass construction boosts backside gain while protecting the solar cells for decades. The 640W module is designed for modern arrays with 1500-VDC system compatibility and a high series-fuse rating, and it maintains output across seasons thanks to a strong temperature coefficient and a wide operating window from deep-cold to desert heat.
