What is the degradation rate of a solar panel & how long it last?
A solar panel''s "useful life" ends when its output falls below 80%, although this does not imply that it is worthless. The panels will continue to provide electricity for many years but at a decreased efficiency. Making power more sustainable and affordable is the way of the future. Investing in a solar panel is a good choice. So, if the
