Sungrow 635W Smart Solar Panel, N-Type Bifacial Double Glass, Black Frame

Sungrow 635W Smart Solar Panel, N-Type Bifacial Double Glass, Black Frame

The Pulson Sungrow SG-66TG4D-X-635 is a high-output smart solar panel designed for commercial and utility-scale PV installations. It combines 635W rated power, 23.5% module efficiency and N-type bifacial technology to generate energy from both the front and rear surfaces.

Integrated smart functions provide module-level monitoring through iSolarCloud, anomaly detection, fault localisation, precision bypass, rapid shutdown and digital lifecycle records. Its durable double-glass construction, self-cleaning functionality and strong mechanical-load resistance support reliable long-term performance in large-scale solar projects.
