Solar (PV) Panel Cleaning
Professional cleaning of photovoltaic modules for higher yields and a longer service life. We remove dust, pollen, bird droppings and weather deposits that can noticeably reduce your system's output over time.
What's included?
Cleaning of the module surfaces
Gentle removal of dust, pollen and environmental grime from the glass surface of the modules.
Removal of stubborn soiling
Bird droppings and dried-on deposits that can affect individual cells.
Cleaning with clear water
Using demineralised or clear water for streak-free, gentle results.
Visual inspection of the modules
Any irregularities such as damage or discolouration are noted during cleaning.
Every watt counts
Photovoltaic modules are permanently exposed to the weather and accumulate dust, pollen and, in some locations, bird droppings over time. These deposits cast shadows on the cells and measurably reduce the system's power output – particularly on shallow-angled modules, where rain doesn't wash the dirt off on its own. Regular cleaning ensures your system operates as close as possible to its actual capacity.
Soiling left on the modules for too long can also become ingrained, making later cleaning harder and, in some cases, permanently damaging the module surface. Regular, professional cleaning therefore contributes not only to higher yields, but also to the long-term value of your investment in the system.
Frequently Asked Questions
It depends on location, tilt and surroundings, for example proximity to farmland, trees or busy roads. After a site visit we recommend a suitable interval.
This depends on the system type and accessibility and is agreed with you or your system operator in advance.
No – we work with soft, module-friendly brushes and demineralised water instead of aggressive cleaning agents or high pressure. Glass surfaces and coatings aren't damaged.
Dust, pollen, bird droppings or soot form a layer over time that noticeably reduces light yield – especially on shallow-angled modules, where rain doesn't wash the dirt off. Regular cleaning recovers this loss and protects against deposits becoming ingrained.
Yes, we clean roof-mounted systems on residential and commercial buildings as well as larger systems on hall roofs or open ground. We clarify accessibility and safety during the free inspection, after which you receive a fixed-price quote.
