Why you should get your solar panels cleaned?

Why is it important to clean my solar panels?

Having dirty solar panels can not only reduce your kerb appeal, but it can also affect the panels performance. Dirt such as dust, tree sap and bird droppings can cover your panels which means sunlight can no longer reach the cells. Therefore, having dirty panels can reduce your system's performance and your return on investment. Whilst regular maintenance is not always required, a clean following the winter can help increase efficiency and make your roofs look more attractive.

When should I clean my solar panels?

Visually, you can often see a build-up of dirt on the surface of your panels. In addition, when you start to see a reduction in your panel's generation, it may be time for a cleaning.

How to clean solar panels?

In most cases, getting your panels cleaned calls for a professional. These professionals can ensure safe access to your panels and clean them correctly using the correct methods. For example:

Cleaning panels with non-abrasive materials will ensure no scratching of your panels, which in many cases could lead to damage that will impact the efficiency and potentially negate your warranty.

In addition, cleaning panels with a soft-wash method means no disruption will occur to the silicone seams, and therefore, water will not get where it is not supposed to be.

My solar panels are self-cleaning.

Whilst the majority of solar panels in the UK are now described as self-cleaning, more is needed. The manufacturers achieve self-cleaning by using a hydrophobic coating. This coating protects the surface and stops water droplets from sticking. This protection also reduced the build-up of dirt on the cells. Nonetheless, homeowners need more than the hydrophobic coating and rain alone in specific locations that are highly polluted, dusty or have regular bird visitors.
