The Trina Solar Vertex TSM-DEG21C.20 is a 650-670W P-type PERC bifacial dual glass module. Engineered for utility-scale plants, it delivers lower LCOE, reduced BOS cost and a shorter payback time while remaining compatible with existing mainstream system components. Multi-busbar technology improves light trapping, lowers series resistance and improves current collection.
Product overview
Original A-grade Trina Solar Vertex photovoltaic modules. The bifacial dual glass laminate is certified against salt, ammonia, sand, high temperature and high humidity, with PID resistance ensured through cell process and module material control. Back side gain can reach up to 25% depending on albedo.
