Our Heliene 400w bi-facial panels are mounted on a green metal roof, about 1.5-2" above the surface of roof
Could we expect any residual solar energy from reflection(s) off the roof? Guess what I'm curious about, does some of the sunlight pass through the panel glass (which then could reflect back)? Curious how bi-facial panels are supposed to be able to capture residual energy from the back side
