High-power N-type TOPCon bifacial module with G12 wafer. For large-scale ground-mount projects.
G12 (210mm) N-type TOPCon cells deliver industry-leading power density for utility-scale projects.
Dual-glass bifacial design with AR-coated glass maximizes energy capture from both sides.
Higher wattage per module means fewer panels, less racking, and reduced installation labor per MW.
25-year product warranty + 30-year linear performance warranty backed by manufacturer.
Full electroluminescence testing. Flash reports with IV curves for every container.
Full container loading with custom wooden crate packaging. All-risk cargo insurance included.
The JUSTSOLAR TOPCon 640W pushes power density higher with 210mm (G12) N-type TOPCon cells in a 132-cell configuration. At 23.1% module efficiency, it is optimized for utility-scale ground-mount installations where maximizing power per unit area directly reduces land, racking, and wiring costs. The G12 wafer format delivers more watts per module, meaning fewer modules, fewer connections, and lower labor costs per MW installed. Dual-glass bifacial construction with 80% bifaciality, combined with an excellent -0.29%/C temperature coefficient, ensures strong energy yield even in hot climates. Compatible with all major string inverters and tracking systems at 1500V DC. Third-party inspection by SGS, TUV, or Bureau Veritas is welcome at any time.
