More details

With compact dimensions of 1722×1134×30mm and a lighter weight of 21kg, it is easier to handle and install across various project types. The dual 1.6mm semi-tempered glass enhances mechanical strength and resistance to environmental stress, while the anodized aluminum alloy frame ensures long-term durability. Designed to operate in harsh conditions from -40°C to +85°C and supporting a maximum system voltage of 1500V DC, it is well-suited for demanding applications.

Equipped with IP68-rated junction box, three bypass diodes, and MC4-EVO2 connectors, it guarantees safe and reliable performance. Flexible 4.0mm² output cables (customizable) further improve installation adaptability. With efficient packaging of 36 modules per pallet and 936 per 40HC container, this panel is an excellent choice for utility-scale, commercial, and high-efficiency bifacial solar projects.
