In rural areas in particular, photovoltaic systems become contaminated by air pollution, leaves and dust, as well as acid rain. Whilst rain can wash some of this away, contaminants increasingly become embedded, reducing the amount of light reaching the panels. The result: the systems become less effective. In heavily soiled systems, output can drop by up to 30%. Long-term contamination can even lead to material fatigue, glass corrosion and a deteriorating glass coating. Depending on the module manufacturer, so-called hot spots may also form after a few years due to shading of the cells. This increases the risk of fire.
With our QLEEN Solar range, we offer professional, portable cleaning systems for domestic and commercial solar power systems.
The rotating brush systems, which clean using demineralised water, enable an environmentally friendly and gentle method of cleaning solar panels. Due to its greater dirt-dissolving power (‘hungry water’), the pure water tends to absorb minerals and binds more quickly and aggressively with dirt particles on the surface, carrying them away from the solar panels along with the dirty water. Dirt, dust and organic deposits are thus sucked up and washed away as if by a magnet.
The result: it protects the system from re-contamination for longer and prevents corrosive fungi, algae and lichens from settling on the solar panels and their frames. Only clean photovoltaic systems deliver the efficiency guarantees promised by the module manufacturer and do not reduce revenue.
Our rotating brushes, driven by two powerful 24 V motors and featuring a swivelling cleaning head, are ideally suited for use with our carbon pole systems
