Of course, one of the most important elements in panel cleaning is water. Users think that ‘rain water‘ can be effective and sufficient for panel cleaning. However, the water to be cleaned must be ‘pure’, purification or osmosis water can be used for this. Cleaning with mains water, well water or transport water shortens the life of solar panels. The panel and water temperature should be parallel in case the panels experience thermal shock during cleaning. In addition to these elements, there are alcohol-based cleaning products in cleaning, but it is very important not to use chemicals that will damage the panels. In order not to damage the solar panels and not to reduce their efficiency, it is vital for SPS installations to maintain routine cleaning and regular maintenance. Stepping on and walking on the panels during cleaning are among the common mistakes made. However, this may cause micro cracks on the panels over time and permanent damage may occur on the panels. In addition, it is necessary to ensure that the method or device used for cleaning does not damage the panels.
