The productivity and performance of a PV system also depend on the cleanliness of the installed panels. But how often do they need this operation?
Let us first specify how a clean module, free of dirt and dust, is able to capture more sunlight and transform it into electricity. Making sure, therefore, that the surface is clean and free of any trace of dirt then becomes of paramount importance. Dust, smog, soot, sand, droppings, leaves, debris, soil, and organic residues often go to settle on the surface of panels , limiting their performance and, in the long run, could be a problem and affect the performance of the PV system itself. Also remember that the modules are connected in series, so even one dirty panel could affect the operation of the entire system.
Hence there is a need for periodic cleaning of PV panels, which is suggested to be done annually. If you have further doubts about the state of your panels it will be sufficient to observe them, if you notice a dull, dusty patina on them then it is definitely time to clean them.
PV PANEL CLEANING: HOW TO KNOW WHEN IT'S TIME TO DO IT
Wondering how you can clearly and confidently tell when your PV panels need cleaning? Compare the yields of the system periodically; if the amount of energy produced is lower than in previous periods, there may be something negatively affecting the yield of the panels.
Also check them visually to note if the level of opacity is significant, as well as to check for dirt of any kind. If present I will be appropriate to clean them, in any case suggested at least once every 12 months.
The best time to do this is usually at the end of winter or in the spring, when heating systems that lead to the formation of soot and smog stop working, but also before what is the plant's peak performance period, which is summer.
WHO TO TURN TO FOR PHOTOVOLTAIC PANEL CLEANING?
Do-it-yourself operations are absolutely not recommended as not only might one not have the proper means for cleaning, but such intervention could also be risky if not done safely.
For the cleaning of photovoltaic panels therefore, it is always advisable to turn to specialized companies that operate daily in this field, among them P.R.E. offers this service and operates in the provinces of Milan, Monza, Bergamo, Pavia, Lodi and throughout Lombardy.
If you wish to proceed with the cleaning of your photovoltaic panels, P.R.E. will be able to provide such support as it is highly qualified in this area and aware of the importance of keeping the surface of the panels in an optimal state at all times.
