It is no longer a secret that solar power and photovoltaic systems require regular cleaning. Just about every system should be cleaned at least once during its service life. Some systems exhibit yield losses of up to 30%. In particular, heavy soiling can be expected on systems installed on agricultural buildings with livestock, industrial plants and on roads with heavy traffic. These systems generate 30% less electricity, and therefore 30% less remuneration for feed-in. Only a clean system can generate maximum yields.
Cost-benefit analysis of a 30-KWP system
The basis for our sample calculation is a system with 30.000 kWh and a remuneration of 0,46 cents/kWh (approx. 13.800 € annually).
