That doesn't seem quite realistic, since the back side isn't getting full sunlight like the front unless the surface behind the panel is a perfect mirror. Depending on what's reflecting onto it, it could still end up worthwhile.
- bullfightonmars 3y agoThe efficiency is most likely a measure of solar radiation striking the surface of the bottomside not the topside.
- gs17 3y agoCorrect, which is why you can't add them and claim 43% efficiency total. If each side was 60% efficient, you wouldn't add them to 120%.
