M210H666 DG 645-665W

M210H666 DG 645-665W

Double glass and frame packaging to ensure module strength. Will produce more energy than a mono-facial module with the same nameplate power. The bifacial module can convert light that strikes both the front face and the back face of the module into electricity. Under the same conditions, a bifacial module will produce more energy than a single-sided module with the same nameplate power.
