Hauts-de-France: specific conditions for solar panels

Hauts-de-France comprises the old regions of Nord-Pas-de-Calais and Picardie and stretches from the Channel coast to the Champagne border. With the ports of Dunkirk and Calais, the Lille-Roubaix-Tourcoing urban-industrial cluster and extensive arable farming, the pollution load for solar panels there is very varied.

Local factors affecting returns

Calais-Dunkirk coastal strip: Salty sea air and industrial precipitation from the ports and ArcelorMittal Dunkirk steelworks spread inland.
Lille-Roubaix-Tourcoing industrial basin: the old textile towns, their modern business parks and the A22 together continuously produce industrial dust and exhaust particulates.
Arable Picardy and Flemish loam: intensive arable farming spreads soil dust and crop protection deep into the region in dry seasons.
Motorway network A1, A22, A25 and A26: the main links between Paris, Brussels and Calais are among the busiest in France.

What that means for your installation

In Hauts-de-France, we recommend one to two cleanings per year, with a second turn for industrial roofs in Lille and Dunkirk, and for agricultural farms in Picardy's fields. We match the schedule to your monitoring data.

Frequently asked questions about solar panel cleaning Hauts-de-France

For homes in Hauts-de-France, we recommend one to two cleanings per year, with a second turn at the coast and in the urban Lille-Tourcoing basin. For large commercial roofs at ArcelorMittal Dunkirk or Toyota Valenciennes, we recommend a quarterly turn.

Rain washes off loose dust but leaves salty deposit, industrial soot and agricultural dust. In a region with so many different sources of pollution, that layer quickly builds up again between showers.

Yes. We clean homes throughout Hauts-de-France and large company roofs in the ports of Dunkirk and Calais, at ArcelorMittal, Toyota Valenciennes, on the logistics parks around Lille and on farms in the Picardy fields.

Customers in Hauts-de-France typically see 10 to 25% yield recovery immediately after cleaning, with outliers in port areas and with steel industries. We back up these figures with your monitoring data.
