Solar panel efficiency is higher than ever, but the amount of electricity that panels can generate still declines gradually over time. High-quality solar panels degrade at a rate of around 0.5% every year, generating around 12-15% less power at the end of their 25-30 lifespan. But, what are the reasons for solar panel degradation?
The production warranties on most solar panels fluctuate as they age due to deterioration. Throughout a solar panel lifespan, a solar panel with a lower degradation rate will produce more energy. The lower the rate of degradation, the better the solar panel. The rate of depreciation of solar panels is also dependent on the brand.
Research has shown that the carbon payback period for solar panels is on average 1-4 years. Even in areas where the sun’s radiation is received at less than 550kWh per m2 such as the northern part of the UK, a typical solar panel will only take around 6 years to pay back its energy cost.
You’ll find the expected solar power degradation rate for the first year in the warranty details. Most solar panel warranties estimate the rate of power degradation to lie between 2% to 3% in the first year, and then 0.7% a year after that. However, depending on the quality of solar panels, it could be as low as 0.25%.
Assuming 12% conversion efficiency (standard conditions) and 1,700 kWh/m2 per year of available sun-light energy (the U.S. average is 1,800), Alsema calculated a payback of about 4 years for current multicrystalline-silicon PV systems.
The short answer is: quite long a time! Solar panels, like all technical equipment, wear down over time and may require replacing. The good news, however, is that they degrade very slowly and can produce electricity even decades later! This doesn’t alter the fact that solar panels do lose efficiency as time goes on.
