Over time, solar panels lose their ability to absorb sunlight and convert it into solar energy due to factors such as hotter weatherand the natural reduction in chemical potency within the panel. This is what is referred to as the “degradation rate”. The lower the degradation rate, the better the panel. When a solar panel. There is technically no expiration date on solar panels.
