Essen: specific conditions for solar panels

Located in the heart of the Ruhr region, Essen bears the legacy of a hundred and fifty years of coal and steel industry. Although the mines have long since closed, the regional air quality remains scarred by industrial precipitation, highway fine dust and dense urban development.

Local factors affecting returns

Legacy of coal mining: decades of underground and surface mining have left fine carbon and metal dust in the soil and air.
A40 motorway: the Ruhrschnellweg right through Essen is among the busiest motorways in Germany.
Industrial suburbs: Bottrop, Gelsenkirchen, Mülheim and Bochum form a contiguous industrial fabric with continuous dust and sulphur deposition.
Pollen Gruga park and Stadtwald: the vast city parks and the Ruhr Valley provide plenty of coniferous and oak pollen in spring and summer.

What that means for your installation

For Essen, we recommend two cleanings per year for homes, and on large company roofs at Evonik, RWE or in logistics parks even a quarterly rhythm. We tailor the schedule to your location.

Longer lifespan: By preventing dirt build-up and hot spots, your entire system will last longer.

Frequently asked questions about solar panel cleaning Essen

Due to the Ruhr load and the A40 motorway, we recommend two cleanings a year for residential properties in Essen. Company roofs at Evonik, RWE and at logistics parks generally benefit from a quarterly cleaning.

Rain removes loose dust but leaves the typical Ruhr mix of carbon, sulphur and metal particles. That layer is responsible for the biggest yield losses we consistently measure here.

Yes. We clean homes throughout Essen and large company roofs at Evonik in Goldschmidt, on the RWE campus, on the old Zeche sites and at logistics parks in Bergeborbeck and Frillendorf.

Customers in Essen typically see 12 to 26% yield recovery immediately after cleaning, with peaks for industrial roofs in the heart of the Ruhr region. We back up these figures with your monitoring data.

We work throughout Essen, including Essen-Mitte, Borbeck, Steele, Kettwig, Werden, Bredeney, Stoppenberg and Altenessen, and in surrounding Ruhr municipalities such as Mülheim, Bottrop, Gelsenkirchen, Bochum and Oberhausen.
