Bifacial Factor and Albedo.
Since we have a dual glass panels, it will generate up to 90Watts from the back side only by reflective light (peak power up to 530W). The panel is made for all types of applications ; off-grid, large utility scale solar farms, hybrid and residential.
When the panel is mounted on triangular frame (at an angle) that will allow the back side to absorb enough energy from the reflected sun rays.
