Duisburg: specific conditions for solar panels

Duisburg hosts Europe's largest inland port and is heartland of the German steel industry with ThyssenKrupp and HKM. That heavier-than-average industrial pressure means solar panels there collect a pronounced metal and dust film on the glass.

Local factors affecting returns

Steel industry: ThyssenKrupp Steel Europe and Hüttenwerke Krupp Mannesmann disperse metal and carbon particles far and wide.
Inner harbour Duisport: container handling, bulk goods and logistics movements continuously generate dust and exhaust residues.
A40 and A59 motorway network: these busy connections are a continuous source of exhaust particulates, especially on rooftops in Duisburg-Mitte and Hamborn.
Pollen: the Duisburg Forest and the green belts along the Rhine deliver oak and birch pollen in spring and summer, sticking to a moist panel.

What that means for your installation

For Duisburg, we recommend two cleanings per year for most roofs, and on large commercial installations in the port or near steel mills even a rhythm of once a quarter. We tailor the schedule to your location and yield dates.

Frequently asked questions about solar panel cleaning Duisburg

Due to heavy industry and port activity, in Duisburg we recommend two cleanings per year for homes. For large commercial roofs close to ThyssenKrupp or in Duisport, we recommend a quarterly rhythm.

Rain removes loose dust but leaves the typical metal and carbon film of the Ruhr steel industry. That layer builds up between showers and is responsible for most of the yield losses we measure there.

Yes. We clean homes throughout Duisburg and large commercial roofs in the port of Duisport, on the Logport I to III logistics parks, at ThyssenKrupp and HKM and on industrial estates in Hamborn and Wedau.

Customers in Duisburg typically see 12 to 28% yield recovery immediately after cleaning, with the biggest gains for industrial roofs close to steel mills. We back up these figures with your monitoring data before and after the turn.

We work throughout Duisburg, including in Duisburg-Mitte, Hamborn, Meiderich, Walsum, Rheinhausen, Homberg, Wedau, Ruhrort and Beeck, as well as in surrounding municipalities such as Mülheim an der Ruhr, Oberhausen, Krefeld and Moers.
