535W Hi-MO X10 Scientist HPBC Half Cell Bifacial Black Frame

The LONGi Hi-MO X10 Scientist LR7-60HVD-535M is a 535W bifacial solar panel built around LONGi's N-type HPBC 2.0 back-contact cell technology. The 120 half-cut cells sit between two glass layers (2.0mm coated tempered front, 2.0mm semi-tempered rear) in a black anodised aluminium frame measuring 1990 x 1134 x 30mm and weighing 28kg. Rated module efficiency is 23.7%, with a bifaciality factor of 70% (+-5%) letting the rear surface add extra yield from reflected light on suitable roofs and ground-mounted arrays. The panel is rated for a maximum system voltage of 1500V DC and operates from -40 to +85 degC, with a first-year degradation below 1% and 0.35%/year after that. Output cabling runs through an IP68 junction box with three bypass diodes. LONGi backs the module with a 15-year materials and workmanship warranty and a 30-year linear power output warranty.
