Photovoltaic panels, like any other installation exposed to weather conditions, are constantly contaminated. According to one of the leading producers of photovoltaic panels – SELFA, “the annual average decrease in power of panels under normal operating conditions, with standard rainfall and no point pollution, is about 4.4%, but with no rainfall, in an industrialized area, with the presence of aerosols and point pollution. even 20% ”. A lot of? It is as if we did not use 1/5 of our installation all year round.
Of course, we cannot clean photovoltaic panels with standard chemicals that we have at home. Cleaning panels is dangerous, especially when installed on a roof. Sometimes the cleaning process requires specialized equipment, but when the panels are located on the ground or in accessible places such as a fence, garage roof, etc. While maintaining responsibility and attention and, above all, using appropriate professional chemicals intended for cleaning photovoltaic panels, we can clean the panels ourselves, yes like the windows in the house.
The frequency of cleaning solar panels is debatable. The dust itself is enough to clean an average of 2-4 times a year, especially when the preparation has hydrophobic properties, which additionally protect the panels against repeated soiling, such as the innovative PROSOLIS preparation. It is best to wash the panels after the grass and trees are dusty. However, spot dirt should be removed on a regular basis, because it can significantly reduce the efficiency of the entire installation. The PROSOLIS POINT preparation quickly and effectively separates the accumulated matter from the substrate, thanks to which you can easily and effectively remove even the most difficult dirt. Generally, solar panels should be washed in the morning when they are not heated to avoid thermal shock. They cannot be used for washing pressure devices as they may damage the surface of the panels. It is necessary to use only products intended for cleaning photovoltaic panels. If the panel needs to be cleaned, only a soft cloth or a brush with soft bristles can be used. Never climb on panels or kneel on them, use telescopic brushes if there is no access to farther dirt.
