Understanding Degradation and the Lifespan of Solar Panels
Solar panel degradation is the gradual loss of a panel''s ability to capture solar energy. This process is inevitable and usually occurs at a rate of around 0.5% per year . Initial light exposure when panels are first installed causes a slight degradation, and exposure to the elements affects panels as they age.
