Nord: specific conditions for solar panels

The Nord department covers the Flemish and Hainaut strip of France, with Lille as its capital and Dunkirk as a major industrial port. Between the ArcelorMittal steel plant, the Lille basin and Flemish arable farming, the pollution load for solar panels there is particularly high.

Local factors affecting returns

ArcelorMittal Dunkirk: one of France's largest steel plants disperses metal and carbon particles far inland.
Lille-Roubaix-Tourcoing industrial basin: together with the logistics hubs along the A22, this forms a continuous source of industrial dust and exhaust particulates.
Coastal strip and salty sea air: the North Sea and The Channel blow salty particles as far as Dunkirk, Grevelingen and Bourbourg.
Arable Flemish loam: the loamy soils of French Flanders release soil dust into the air, especially during dry periods.

What that means for your installation

In the Nord department, we recommend two cleanings per year for most roofs, and a quarterly turn for large installations at ArcelorMittal Dunkirk or Toyota Valenciennes. We tailor the schedule to your monitoring data.

Frequently asked questions about solar panel cleaning Nord

Due to heavy industry and the borders with the sea and Belgium, we recommend two cleanings a year for homes in the Nord department. Commercial roofs in steel, automotive or textile industries generally benefit from a quarterly rhythm.

Rain washes off loose dust but leaves salty deposit and industrial soot from Dunkirk and Lille. That layer is responsible for the large yield losses we consistently measure here.

Yes. We clean homes throughout the Nord region and large company roofs at ArcelorMittal Dunkirk, Toyota Valenciennes, on logistics parks around Lille, on textile parks in Roubaix and Tourcoing, and on farms in French Flanders.

Customers in the Nord department typically see 11 to 27% yield recovery immediately after cleaning, with the highest gains for industrial roofs at ArcelorMittal and in the Lille basin. We back up these figures with your monitoring data.

We work throughout the Nord department, including in Lille, Roubaix, Tourcoing, Dunkirk, Valenciennes, Cambrai, Douai, Maubeuge, Armentières, Wattrelos, Marcq-en-Barœul and Hazebrouck.
