Solar PV Cleaning

Why Clean Solar Panels?

Solar panels work by allowing light into the solar cells. The more light that hits a panel, the more power it will generate. Due to the upwards angle of solar panels, they are more prone to bird droppings and a build-up of general dust and dirt that does not wash off with just rain. This reduces the amount of light hitting the panel and reduces its output. As the projected energy figures claimed by solar panel manufacturers and installers are based on the optimum performance of clean solar panels, this build-up of dirt can adversely affect the panel’s ability to meet those projections. So it is important to clean solar panels in order to protect and maintain your investment.

While solar panel cleaning  is relatively new, in many parts of the world solar panel cleaning has been around for a long time.  Early adopters of the technology soon realized that if their solar panels were not cleaned regularly, they would not run at their optimum performance.  There has been study in the U.S. suggesting solar panel cleaning is not necessary in some of their climate, but it is proved that solar panel cleaning is necessary for optimal performance of your solar power system.

Some solar panel manufacturers and installation companies have made solar panel cleaning a condition of their warranty. Should you have problems with your solar panels, if you do not have proof of regular solar panel cleaning by professionals, your solar panels may not be covered by the warranty.
