Solar & energy
Clean surfaces. Full performance. Professional cleaning with softened water and special brushes.
Photovoltaic systems are exposed to various environmental influences every day. Soiling such as dust, bird droppings and pollen forms a stubborn layer. This deposit blocks the sunlight considerably. Regular cleaning protects your investment from such damage. Through our professional cleaning we quickly restore the increased performance and lifespan of your solar system.

Our scope of services
As a specialist in building cleaning, we clean the module surfaces professionally, gently and thoroughly. We use specially developed brushes and pure water, and we avoid aggressive cleaning agents. This method prevents limescale marks and is particularly gentle on your modules.
For large open areas and solar parks we rely on robotic technology, among other methods. This lets us clean even large surfaces reliably and with modern equipment in a single deployment. That guarantees maximum efficiency across the entire site.
After the construction phase there are many sources of soiling, such as building dust or adhesive residue. Professional photovoltaic cleaning right after installation ensures that your system works efficiently over the long term.
Depending on the location and the degree of soiling, we recommend one to two deployments per year. Professional cleaning prevents the formation of so-called hotspots on the module surface and secures your yield over the long term.
During every solar system cleaning, our professionally trained team checks the frame and the cables. You receive a report, so the value retention of your photovoltaic systems is always documented.
Why cleaning pays off
Scientific studies prove that soiled solar modules produce considerably less electricity. Even with a low degree of soiling, the losses are measurable. If PV systems are maintained regularly, however, you as the operator can harvest significantly more.
For an average solar system, professional photovoltaic cleaning usually pays for itself within a few months. The cost of thorough cleaning is only a small fraction of the money recovered.
DIORA cleans every photovoltaic system gently, without residue and professionally. This secures high efficiency and the best value retention over the long term in Rheine and the surrounding area.
