Automatic Solar Cleaner

Solar and photovoltaic plants are symbols of clean energy generation. In order to achieve the optimum efficiency as well as the calculated service life of the plant, the solar panels have to be clean. Permanent soiling caused by environmental influences, dust, flower pollen, mosses etc. reduces the solar performance and efficiency. In the case of agricultural farms and livestock farming, ammonia gases lead to an additionally increased degree of soiling (heavy soiling may reduce profits by 20 – 30 %). Even smallest contaminations caused by bird droppings, mosses, lichens etc. may – due to the series connection of modules – reduce the performance and efficiency of the complete plant, as the weakest module determines the total output. However, it is not only the financial loss, which gives reason to concern! Soiling can attack panels’ coatings and seals. Incoming water then causes damages to the complete system. The solar and photovoltaic plants become susceptible to faults and failure.
