why, how and what ??? Is cleaning really necessary?? For power generation technologies with moving parts the need for regular maintenance is obvious, but for photovoltaics, the necessity of this insight is only slowly taking hold. Installers, particularly in the private sector, usually portray photovoltaic systems as practically maintenance-free. The conventional wisdom is that a module tilt of at least 15 degrees ensures adequate self-cleaning from rain. But in the view of German project planning company Phoenix Solar, there are limits to self-cleaning. According to company spokesperson Isabell Struwing, “Areas with local soiling due to industrial or agricultural activities, or arid desert-like locations with high aerosol levels, have to be checked individually to see if module cleaning makes sense.� And there are a great many places that meet those criteria. What first comes to mind are very dry locations with high temperatures, which are also often near the coast where the air has high aerosol content.

An example of the prototype: The initial prototype as a 1.6 meter long, approximately 1 meter wide robot that moves along the surface of the modules like a miniature tracked vehicle. The robot was consciously designed to be very flat, making it resistant to high winds. The Servitor uses rotating brushes just like other cleaning robots which are already available. The cleaning concept originates from the Danish Technological Institute (DTI). In locations with excessive dirt, a water-cleaning system will be used; in deserts with little available water, dry cleaning may also be possible.

Cost-effective and performance increasing cleaning technology: The PV-Servitor focuses on concepts for a fully autonomous cleaning robot for ground mounted large scale photovoltaic power plants consisting of several 100 kW units. The PVServitor is able to automatically search for dirt and damages, clean glass surfaces of solar modules in several areas of up to 2,500 square meters in an unrestricted way, also perform spot cleaning as well as capable to automatically record the status of the plant and modules to analyze damage in the cells, so that the requirement for manual inspection of people at the plant is reduced. This saves travel costs and labor costs. Its application will increase the electricity output of the PV plant by 8% at a service cost of only 3%, thus resulting in a 5% user-benefit by cost reduction of the electricity yield.
