Solar panels age with you, though at a much lower pace. It is usual to see a very small degradation in energy output with time which is due to the very nature of the solar module technology. Generally, annual degradation of modules is in the range of 0.3% to 0.5%. However, in the first year of your installation, this degradation may be higher.
