Solar panels lose 0.5% output per year. Here''s what that costs over 25 years, how to read a performance warranty, and which panel types degrade slowest.
The degradation rate of a solar panel is the pace at which its power production decreases over time. The majority of the solar products now on the market degrade at a rate of 0.5% each year
Solar Panel Degradation Loss per Year Estimate how much solar panel power capacity remains after years of use based on annual degradation rate.

Calculate how your solar panel efficiency and production decline over time. Model output at year 5, 10, 15, and 25 with manufacturer-specific degradation rates.
On the horizontal axis, we have the cumulative installed capacity of solar panels, and on the vertical axis, the cost. Both are measured on logarithmic
Solar panels capture the sun''s energy and convert it into electricity for your home. Here''s how they work and their benefits.
By consolidating the literature on the long-term degradation of PV modules published until 2023, we discovered a mean and median degradation rate of 1.1 %/year and 0.94 %/year, which is
Solar panel degradation rate is the annual percentage decline in power output, typically 0.5%/year for mono-PERC, 0.3-0.4% for HJT and TOPCon, and 0.7-1.0% for polycrystalline.
The National Renewable Energy Laboratory mentions that the degradation rate is around 0.5% to 0.8 % per year but varies depending on the model, brands, and types of panels.
NREL''s 2024 meta-analysis of over 54,000 systems worldwide confirms that modern panels degrade at a median rate of 0.5-0.7% per year, significantly better than the 1.0% industry
How much do solar panels degrade each year? A 2012 NREL Study suggests that on average solar panels degrade at a rate of 0.8% per year with an initial performance loss of between
Calculate solar panel degradation loss per year. Estimate remaining panel capacity and efficiency after years of operation using our free online calculator.
The widely cited industry average is roughly 0.5% per year, meaning a panel retains about 87.5% of its original capacity after 25 years. High-performance modules from premium manufacturers can hold
The solar panel degradation curve shows an average solar panel degradation per year of about 1%. Most warranties guarantee 90% efficiency after 10 years and 80% after 25–30 years.
