How Long Do Solar Panels Really Last?

It is no surprise that the quality of a solar panel can impact the rate of degradation and how long a solar panel lasts. While some solar panels may have a cheaper upfront cost, you will pay the price in the long run. Cheaper solar panels tend to use low quality solar glass, and a reduced amount of aluminium in order to keep the price down. The thinner frames and lower quality protection, make the panel more vulnerable to damage.

Although panel degradation is unavoidable, solar panel efficiency is higher than ever. Thankfully, here at Deege Solar we only install high quality Tier 1 Solar Panels, meaning that the rate of degradation is at a minimal. High-quality solar panels degrade at an average rate of around 0.4-0.5% every year. This means even over long periods, the solar panels loose very little of their total capacity. Only generating 12-15% less power at the end of their 25-30 year lifespan.

As leading UK solar installers, at Deege Solar we only install premium products. Designed to maximise your solar panel system’s efficiency and output. It is important to do your research on the products you will be having installed. For example, we commonly install Hyundai Solar Panels which have a Premium 20.4% Module Efficiency, and Growatt who supply the number 1 worldwide inverter

If we wouldn’t have it on our own home, we simply won’t install it on yours. Take a look at our list of the Best Solar Panels the UK have to offer.
