Solar Panels have rapidly become one of the UK's top renewable energy sources with 1 million homes across the UK using them to produce green energy and save money on their electricity bills. As a relatively new energy source there are still many questions surrounding solar panels and how long do they last is one of the biggest.
Studies show that solar panels typically last 25-30 years, which is best known as the optimal rate by manufacturers. However, solar panels simply don't stop working after 25-30 years. They will continue to produce electricity, just at a lower rate due to panel degradation. So when we say that your solar panel's lifespan is 25-30 years, we are really referring to the optimal performance duration.
Why Do Solar Panels Degrade?
One of the main reasons a Solar Panel degrades, is because of long-term exposure to UV rays and adverse weather conditions. High temperatures and warmer climates are likely to increase degradation rates. As well as, extreme cold temperatres and heavy snow which affects solar panels the most. Here in the UK, we aren't usually exposed to extreme weather, so even after 20 years your Solar Panels should still retain 96% of their generation capabilities.
