Solar Panel Cleaning Equipment and Tools


Written by qualified solar engineer Carlos. Last updated:

One of the factors that reduces the performance of your solar panels is the presence of dust on the glass of the modules.

Performance reduction can be as low as 2% annually and as high as 30% annually in the worst cases. Therefore, keeping constant solar panel maintenance and cleaning is essential to guarantee optimum energy yields across the year.

Despite that water and cloth may be simply used for PV system cleaning, other solar panel cleaning products may offer a simpler, faster and better approach for this maintenance. Solar cleaning equipment as brushes, extensions, squeegees, robots, and solutions are perfect for this purpose. Here you will find some of the top options for your PV system.

Solar Panel Cleaning Kits

Among solar panel cleaning products, the most common is a cleaning kit. These kits include multiple extension poles, carrying bags, brushes, cloths, hose interconnections, and more. You will find all the tools that you need to perform the appropriate cleaning.
