Recently I read about a solar panel that was supposed to be running at 27% efficiency. They suposedly did this by concentrating more light onto the panel with mirrors.
I've done this myslef but am pretty sure that this would decrese the lifespan of the panel itself.
In other words, if it incressed from 9% to 27% then it would be a 3 times output thus fighting against more resistance which is the chemical change between the two doped silicon plates. Overall this would decrease the lifespan 3^2 which is 9 times shorter. The 30 year panel is now a three and a third year panel and needs constant replacement.
