Photovoltaic Cleaning Devices: Maximum Performance
The topic of photovoltaics has recently gained in importance. More and more company buildings are also equipped with PV roof systems. An often neglected topic: cleaning. This is where photovoltaic cleaning devices come into play. What they do and why cleaning is so important for the lifespan of PV modules is reported in the following Handelsblatt article.
Why should PV systems be cleaned?
There are several reasons for cleaning PV systems. Regular cleaning with photovoltaic cleaning devices actually extends the lifespan of the PV modules and thus reduces the risk of damage. Dirt, dust and bird droppings constantly burden the systems.
Regular cleaning also saves money, of course. Large roof systems with up to four megawatts can produce up to four million kilowatt hours. A loss of about ten percent corresponds to approximately 38,000 euros with a feed-in tariff of, for example, 0.095 euros.
Therefore, the cleaning and maintenance of PV systems should ideally be an integral part of facility management. When planning such a system, owners should definitely include cleaning in order to keep follow-up costs low from the start. A really well thought-out arrangement of the solar modules and a simple water connection can help a lot.
What does a photovoltaic cleaning robot do and thus the lifespan of the PV modules is extended?
Cleaning robots clean swimming pools, pools and window systems. They take over the tedious work and ensure cleanliness. The specially developed photovoltaic cleaning robot cleans solar systems. Dust and bird droppings contaminate the PV modules and affect their lifespan. Therefore, the robot cleans regularly to maximize energy production and minimize the risk of hotspots.
The modular robots consist of seven lightweight components that can be quickly assembled. Once on the surface, they are controlled by radio remote control and clean the panels. The robot stops automatically at the edge of the solar surface to remain safe. Mostly it cleans with water, in desert regions also dry. The matching treads for both cleaning methods are offered. The treads are easy to change thanks to Velcro.
