Cleaning solar panels in Zeeland

Name: Solarco
Rating: 5

With the North Sea coast, the Westerschelde estuary and the Vlissingen-Terneuzen chemical cluster, solar panels in Zeeland get a double load of salt and industrial precipitation. That combination leaves a stubborn film on the glass that noticeably reduces your efficiency. We clean your installation streak-free with osmosis water.

Zeeland: specific conditions for solar panels

Zeeland is the province with the longest coastal profile in the Netherlands and at the same time houses the Vlissingen-Terneuzen port cluster with Dow Chemical and heavy industry. This unique combination makes solar panels there ideally exposed to salt and industrial precipitation.

Local factors affecting returns

Salty sea air: the North Sea, Western Scheldt and Eastern Scheldt blow salt particles deep inland, even on Walcheren and in Zeeuws-Vlaanderen.
Westerschelde industry: Dow Chemical Terneuzen, Yara Sluiskil and the Vlissingen-Terneuzen ports are one of the largest chemical clusters in the Netherlands.
Polder agriculture: arable farming on Walcheren, Schouwen-Duiveland and Tholen releases soil dust and crop protection into the air, especially in dry summers.
Birds in nature reserves: breeding colonies in the Drowned Land of Saeftinghe and Het Zwin locally leave patches on installations with low gradient.

What that means for your installation

In Zeeland, we recommend two cleanings per year for roofs on the coast and near the Westerschelde industry. For inland roofs, one thorough cleaning is sufficient, possibly supplemented by a second one in summers with lots of salty easterly wind.

Frequently asked questions about solar panel cleaning Zeeland

On the Zeeland coast and in the Westerschelde basin, we recommend two cleanings per year. For inland roofs on Walcheren or Schouwen-Duiveland, one thorough cleaning is usually sufficient.

Rain washes off loose dust but leaves salty deposit and industrial precipitation from Terneuzen-Sluiskil. Especially in a coastal province like Zeeland, that layer quickly rebuilds.

Yes. We clean homes throughout Zeeland and large company roofs in the ports of Vlissingen, Terneuzen and Sluiskil, at Dow Chemical, Yara, Lamb Weston and on arable farms in Tholen, Walcheren and Zeeuws-Vlaanderen.

Customers in Zeeland typically see 10 to 25% yield recovery immediately after a thorough cleaning, with the biggest gains on the coast and in the Westerschelde industrial zone. We back up these gains with your monitoring data.

We work throughout Zeeland, including in Middelburg, Vlissingen, Goes, Terneuzen, Hulst, Tholen, Zierikzee, Oostburg, Sluis, Sint-Maartensdijk, Burgh-Haamstede and Renesse.
