All these impurities are deposited on the panel, damaging the yield over time. If you do not provide a periodic cleaning of photovoltaic systems, it is possible to reach about 20-25% less of performance. Over the years it could incur therefore to a deterioration of the panel, decreasing its power receptor, whether the maintenance of the photovoltaic panels would not be carried out.

Assuming that a plant of 50 kWp can have a gain of around € 23,000 per year, with a loss of just 10% you will lose 2300 Euros, growing worse if nothing is done.

Depending on the type of soil and location, you can plan 2-3 times cleaning operationsper year: the first in March-April and the second in July-August and the third in September-October.
