I for one am not believing it. When I did some testing on my panels I saw a proportional drop off in current. Shade 1/4 of the panel and see a 25% reduction in output."The reduction in power from shading half of one cell is equivalent to removing a cell active area 36 times the shadow's actual size."
And if they did not work at all then many would be in the dark and people would have stopped using them years ago.
I see you running, tell me what your running from
Nobody's coming, what ya do that was so wrong.
