Cleaning solar panels in Groningen

Name: Solarco
Rating: 5

Between the Eemshaven, the Wadden Sea coast and the vast fields of the Oldambt, solar panels in Groningen get industrial precipitation, saline and arable dust all at the same time. That mix puts a persistent film on the glass that gradually depresses your yield. We safely clean your installation with osmosis water.

Groningen: specific conditions for solar panels

Groningen combines the vast arable land of Het Hogeland and Oldambt with the heavy industry and data centres of Eemshaven and the Wadden Sea coast. That unique mix gives solar panels there a varied load of saline, particulate and arable dust.

Local factors affecting returns

Eemshaven industry: coal, gas and biomass power plants and data centres in Delfzijl and Eemshaven deliver particulates and industrial particles onto rooftops in a wide perimeter.
Arable dust: The Oldambt and Het Hogeland are among the most extensive arable areas in the Netherlands, with a lot of soil dust in dry summers.
Wadden and sea salts: Salty air from the Wadden Sea blows inland and creates a salt film on the panel surface.
Pollen reeds and grasses: the Lauwersmeer area and its vast meadows yield reed and grass pollen that sticks to a damp panel.

What that means for your installation

For most Groningen roofs, one annual cleaning is sufficient, with a second turn for installations in and around Eemshaven or near large arable farms. We tailor the rhythm to your location and monitoring data.

Frequently asked questions about solar panel cleaning Groningen

For homes, one thorough cleaning per year is usually sufficient. Company roofs in Eemshaven, Delfzijl or at large arable farms in Oldambt usually benefit from two cleanings per year.

Rain washes off loose dust but leaves the combination of industrial precipitation from Eemshaven, arable dust and salt. That layer is exactly what undermines your long-term efficiency.

Yes. We clean homes throughout the province of Groningen and large company roofs in Eemshaven, data centres in Eemsdelta, and arable farms in Oldambt and Het Hogeland.

Customers in Groningen typically see 9 to 22% yield recovery after cleaning, with the highest gains around Eemshaven and on large arable roofs. We back up these gains with your pre- and post-turn monitoring data.

We work throughout the province of Groningen, including in Groningen-city, Hoogezand, Veendam, Stadskanaal, Winschoten, Delfzijl, Eemshaven, Appingedam, Uithuizen, Leek, Zuidhorn and Ten Boer.
