Modules Cleaning

PV panels should be clean and dust free.

This is one of the major disadvantages of solar panels. In many cases, you cannot wash them yourself, as you must have the appropriate cleaning material.

Another problem is that going to the roof (where solar panels are most often installed) is difficult and risky.

Photovoltaics lose their effectiveness due to the subsidence of the following pollutants:

Fine particles such as exhaust gas
Dust from the fields, especially during the harvest
Sand from the sea
Bird droppings
Down
These factors contribute to reducing the efficiency of solar panels. In extreme cases, the loss of performance can reach up to 20%!
