How often do solar panels degrade?
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?
What happens if a solar panel goes bad?
This type of degradation doesn't happen often, but when it occurs, it can reduce a panel's performance by 30% or even more. Quality – Low-quality components in a solar panel can result in a number of problems like reduced efficiency, increased maintenance costs, and reduced lifespan.
