DMEGC 645W N-Type Bifacial Double Glass Solar Panel The DMEGC DM645G12RT-B66HSW is a high-output 645W N-type bifacial solar panel designed for commercial, agricultural, ground-mounted and other large-scale PV installations. Its high 23.9% module efficiency helps maximise installed capacity where strong output per panel is required. The module combines N-type mono-crystalline cells with a bifacial double glass design. It can generate electricity from light reaching both the front and rear of the panel, while the two layers of 2mm heat-strengthened glass provide robust protection for demanding outdoor environments. Features High 645W rated output With a rated maximum power of 645W, this large-format module is well suited to projects where reducing the number of panels and associated balance-of-system components can improve installation efficiency. 23.9% module efficiency Advanced N-type mono-crystalline cell technology delivers 23.9% efficiency at standard test conditions, supporting high energy yield from the available installation area. Bifacial energy generation The module can use reflected light reaching its rear surface to provide additional generation. Actual bifacial gain depends on the mounting height, surface reflectivity, row spacing and other site conditions. Durable double glass construction The front and rear covers use 2mm heat-strengthened glass, with an anti-reflective coating on the front. The module is rated for a maximum test load of 5400 Pa on the front and 2400 Pa on the rear. Long-term warranty protection DMEGC provides a 15-year product warranty and a 30-year linear power warranty. The datasheet specifies no more than 1% first-year degradation and no more than 0.35% annual degradation over 30 years. Warranty terms and installation requirements apply.
