South Holland: specific conditions for solar panels

South Holland is home to the port of Rotterdam, the Westland and the The Hague-Rotterdam-Dordrecht urban axis. Because of that concentration of petrochemicals, greenhouse construction and urban emissions, solar panels here receive the heaviest industrial pollution load in the Netherlands.

Local factors affecting returns

Rotterdam port: Pernis, Botlek, Europoort and the Maasvlakte together form one of Europe's largest petrochemical clusters, with intensive particulate matter and sulphur precipitation.
Greenhouse construction Westland: the Westland and surrounding area of Naaldwijk produce pollen, crop protection and greenhouse condensates in a contiguous area of thousands of hectares.
Urban ring road A4, A12, A20: the Randstad's busiest connections create continuous exhaust particulates in The Hague, Rotterdam and Dordrecht.
Coastal strip: Kijkduin, Hoek van Holland and Scheveningen bring salty sea air inland, with deposits up to the Rotterdam skyline.

What that means for your installation

In South Holland, we recommend two cleanings per year for most roofs, with monthly maintenance for large installations in the port or Westland. We tailor the rhythm to your location and monitoring dates.

Frequently asked questions about solar panel cleaning South Holland

Due to the combination of port, greenhouse and urban ring, we recommend two cleanings per year in South Holland. On large company roofs in Pernis, Botlek or the Westland, a quarterly turn can be cost-effective.

Rain washes off loose dust but leaves petrochemical precipitation, sulphur residues and greenhouse residues just sitting there. That layer is responsible for the creeping loss of efficiency we find time and again in monitoring data.

Yes. We clean homes throughout South Holland and large company roofs in the port of Rotterdam, at Shell Pernis, on the Maasvlakte, on the TU campus in Delft, at distribution centres in Schiedam and on greenhouse farms in Naaldwijk and ‘s-Gravenzande.

Customers in South Holland typically see 12 to 28% yield recovery immediately after cleaning, with outliers in the Port of Rotterdam. We compare those gains with your pre- and post-turn monitoring data.

We work throughout South Holland, including in Rotterdam, The Hague, Leiden, Delft, Dordrecht, Schiedam, Vlaardingen, Zoetermeer, Gouda, Capelle aan den IJssel, Naaldwijk, Spijkenisse, Alphen aan den Rijn and Ridderkerk.
