Lille: specific conditions for solar panels

Lille is the beating heart of the Métropole Européenne and is surrounded by Roubaix, Tourcoing and Villeneuve-d'Ascq. Between the busy A1, A22 and A25 motorways and the legacy of the textile industry, solar panels there are under permanent urban and industrial pressure.

Local factors affecting returns

Urban traffic and A1/A22/A25 interchange: Lille is located at one of the busiest traffic junctions in northern France, resulting in continuous exhaust particulates.
Heritage textile industry: factory buildings in Roubaix and Tourcoing have left fine textile fibres and industrial dust in the air for generations.
Pollen and city parks: the Parc de la Citadelle and the trees along the Boulevards provide plenty of pollen and lint in spring and summer.
Proximity to Belgian border: cross-border logistics traffic along the A22 is creating additional particulate matter in Mouvaux and Tourcoing.

What that means for your installation

In Lille, we recommend two cleanings per year for most roofs, with a third turn for large commercial installations on logistics parks or close to the A1. We match the rhythm to your monitoring data.
