The cleaning and maintenance of solar panels is essential for their proper functioning. This should be carried out by a specialised person in order to get the most out of the cleaning of solar thermal plates. The cleaning of the solar panels makes them capture the photovoltaic energy much better and gives them a better yield. If the solar panels are not cleaned, the result would be to replace the system, which would be more expensive than cleaning.
Rainwater and air help to keep them clean, but are not the best option for cleaning. Dirt can reduce their performance in the range of 8% to 15%, which would be considerable losses per year. The simplest way to clean solar thermal is with soap and water and drying with a cotton cloth. These cleaning tasks should be carried out early in the morning when the sun is not too strong or in the late afternoon before dark.
