Top Brushes for Professional Solar Panel Cleaning

Solar cleaning can be quite challenging, specially if you do not have the right tools for each job. There is a variety of tools and equipment that a professional solar cleaner needs and, for the majority of the cleaners, the most important is the manual brush. Manual brushes come in all shapes and sizes and finding the right one can be hard. Below is the list of the brushes that gather more consensus between professional solar cleaners. For the majority of PV plants, a soft brush is enough to get the expected results. Soft brushes are great since they will not damage the panels and the finishing quality will be high; however, the choice of softness depends on the type of soiling to be removed. For this reason, you should make sure you use the right type of brush for the soiling photovoltaic solar panels. The scale of the plant is also an important factor when choosing between a water fed pole (WFP) and a rotary brush.

Within the world of professional solar panel cleaning, there is a wide range of brushes from different brands, each with its unique characteristics. Whether you seek a versatile workhorse like the Tucker Alpha Nylon, capable of both glass and solar cleaning, or the high performance of the Tucker Solar, designed exclusively for solar panel maintenance, these two brushes are excellent options. For those battling heavily encrusted dirt and tenacious contaminants such as lichens, the Gardner Ultimate Stiff Brush emerges as the go-to solution. Its harder bristles will help you get the job done faster. When looking to tackle bigger jobs or just save your shoulders, the Solatecs C and the Qleen RotaQleen are the ones elected by the cleaners. The Solatecs C brush is high pressure water driven therefore eliminates the need for batteries, allowing you to work for as long as you want without worrying about the charge level. If you hate managing high pressure hoses, the Qleen RotaQleen brush, since it is battery operated, will give you more freedom of movement and allows efficient brushing without the constant need for water. The use of chemicals will also be easier since you can brush without water. And when cost-effectiveness is paramount, the Unger nLite Solar Radius Brush, from a renowned industry leader, provides a low-cost yet reliable alternative.
