How Long Do Solar Panels Last?

How Long Do Solar Panels Last?

The longevity of solar panels has improved over the past decade, with many of the latest solar panels lasting up to 50 years. As time passes, the efficiency of solar panels can decrease (also known as the rate of degradation) which is typically dependant of the type and quality of solar panel installed. Other factors that can influence the degradation of solar panels including the maintenance and the quality of the installation.

Solar panel maintenance

Owning solar panels can provide you with clean green energy and a reduction in your energy bills, however, ensuring they are maintained and performing at the optimum efficiency could save you money and increase the longevity of your panels. Several maintenance tips to ensure your panels are performing at their optimum include:

  • Ensuring your solar panels aren’t in shaded areas.
  • Keep an eye on your inverter warning panels to ensure there aren’t any warning lights
  • Installing automated cleaners like a sprinkler system or scheduled appointments with a solar panel cleaning company

Cleaning solar panels is very easy, often the hardest bit is getting access to the panels. If cleaning the panels on the roof, ensure that you have the necessary safety equipment as the roof can be slippery. Using a soft brush or rag with biodegradable soap is recommended when cleaning solar panels, as hard equipment or harsh chemicals can damage the panels and lead to increased degradation.

What affects the longevity of solar panels?

One of the main factors that can impact the life of solar panels are the quality of solar panels installed. There are many cheap solar panels on the market, and it is often tempting to go with the cheapest quote when getting solar panels installed but often cheaper quotes can mean cheap lower-quality panels.

Why is the life of solar panels important? As your solar panels generate electricity year after year, it is often between 10 – 20 years before your solar panels have generated enough savings to cover the initial cost of installation. Therefore, ensuring your panels are performing at an efficient level during this time is important to ensure they pay for themselves. Furthermore, after they have paid for themselves, you want to continue to reap the rewards of your solar panels producing energy and reducing your reliance of the ever more expensive grid energy providers.
