How much power does a solar panel lose a year?

In the past, solar panels would typically see a decrease of 1% or more in power output each year. This is known as the solar panel degradation rate. According to a 2012 study by The National Renewable Energy Laboratory (NREL), modern solar panels show no more than 0.8% loss of power per year.

Do solar panels lose efficiency over time?

Yes, solar panels lose efficiency over time. The loss in solar panel efficiency over time is called degradation and it is a natural consequence of exposure of the solar panel to ultraviolet rays and adverse weather conditions. The National Renewable Energy Laboratory estimates this degradation to be between 0.5% to 0.8% per year.
