Suited for rooftop/distributed generation applications, Maxima GxB-340W (72-cell) and GxB-280W (60-cell) bi-facial modules utilize third generation of 156 mm HCT-based PV cells in frameless, double glass design. Sunpreme Solar 2.0 HCT bi-facial cells come with production level cell efficiencies of ~21% for front illumination only, resulting in modules with outputs from 330–350 W DC for 72-cell modules; bi-facial mounting boosts AC energy output with back capturing reflected/diffused lights.
