Astronergy ASTRO 6 645W Twins (Pallet of 31) Bifacial PERC+ Solar Panels CHSM66M(DG)/F-BH-645W
Shipping Notice for 600W+ Solar Panels
All solar panels rated 600W and above exceed liftgate size restrictions and cannot be unloaded via liftgate. Residential deliveries require the customer to provide appropriate unloading equipment (forklift, skid steer, or equivalent) at the delivery location. Failure to provide equipment may result in unloading by hand or re-delivery fees assessed by the carrier.
The Astronergy CHSM66M(DG)/F-BH 645W is a high-power bifacial dual-glass solar module engineered for commercial, industrial, and large-scale photovoltaic applications.
Built using advanced PERC+, multi-busbar, and half-cut cell technology, this module delivers exceptional energy production, enhanced reliability, and lower balance-of-system costs. Designed with bifacial power generation capabilities, the module captures sunlight from both sides to increase total energy yield and improve project returns.
The ASTRO 6 Twins platform incorporates non-destructive cell cutting technology, PID resistance, and durable dual-glass construction to provide outstanding long-term performance. With up to 20.8% module efficiency, a 15-year product warranty, and a 30-year linear power warranty, the CHSM66M(DG)/F-BH-645W delivers dependable energy production for demanding solar installations.
