650-watt bifacial solar panels with 156 cells are high-capacity modules designed primarily for large-scale utility projects and commercial installations. These panels use bifacial technology to capture sunlight from both the front and rear sides, which can increase energy yield by up to 30% depending on the surface reflectivity (albedo).
Technical Specifications
Based on datasheets from manufacturers like Jinko Solar, Solar N Plus, and Schutten, typical specs include:
Cell Type: N-type Monocrystalline, often utilizing TOPCon (Tunnel Oxide Passivated Contact) technology for higher efficiency and lower degradation.
Module Efficiency: Typically ranges from 22.5% to 23.3%.
Dimensions: Approximately 2465 x 1134 x 30 mm (about 8.1 x 3.7 feet).
Weight: Roughly 34 kg to 34.5 kg (75 lbs), often featuring double-glass construction for durability
