If a plant is soiled, not only the yields will be reduced, but also the assumption can arise that there might be some kind of defect in the system. This makes a cleaning of the solar modules inevitable. In most cases, such cleaning operations are carried out using a telescopic rod with a cleaning brush on top of it. Unfortunately, this cleaning method is not suitable for all kinds of photovoltaic plants and is also very time-consuming.

The new cleaning device PvSpin promises more flexibility and economic efficiency. It works on the basis of two cleaning brushes rotating in opposite directions that are only driven by water pressure and remove soilings in a quick and material-protecting manner.

As the complete device only weighs only about 15 kg, it can be let down from the ridge and then can be ergonomically operated by one person.  
Tight dirt is removed by the rotation of the brushes and the filtered water without any problems. The guidance along the module frames that makes cleaning operations even more convenient is also worth mentioning.

 The price-performance ratio makes this device especially attractive to plant owners, cooperative societies and farmers. Solar installers have the chance to expand their range of services.
