Product Description
435-455W Bifacial Dual Glass 9BB Half-cut Mono Perc Solar Panels
This 144-cell bifacial double-glass monocrystalline solar panel delivers front-side power ranging from 435W to 455W with a high module efficiency up to 20.90%. Built with 9-busbar mono silicon cells, it captures extra energy from reflected light via the rear side, bringing up to 25% power gain compared with the front-side rated output.
Rated for 1500V DC system voltage, this module adopts dual 2.0mm semi-tempered glass structure for outstanding durability. It can withstand harsh environments, supporting a wide operating temperature range from -40℃ to +85℃ and high mechanical load of 5400Pa on the front surface. With low temperature coefficients, it maintains stable power output even under high-temperature conditions. Ideal for utility-scale solar farms, commercial rooftop projects and ground-mounted PV systems.
