Utrecht: specific conditions for solar panels

Located at the intersection of the A2, A12 and A27 motorways, the province of Utrecht has a high population density, intensive greenhouse cultivation around Bunnik and Houten, and extensive forests on the Heuvelrug. That context puts on solar panels a combination of exhaust particulates, pollen and urban precipitation.

Local factors affecting returns

Junction A2, A12 and A27: Utrecht is at the Netherlands' busiest traffic junction, with continuous deposition of exhaust particulates.
Greenhouse construction and tree nurseries: Around Bunnik, Houten and Vleuten, horticultural companies deliver lint and crop protection residues.
Pollen Utrechtse Heuvelrug: the forests on the Heuvelrug spread large quantities of pine and oak pollen to urban centres in spring.
Urban soot layer: boilers and construction activity in Utrecht-city and Nieuwegein leave a greasy soot film.

What that means for your installation

In the province of Utrecht, one annual cleaning is usually sufficient for homes, with a second turn for roofs close to the A12 or A2 motorways, in horticultural areas or in forest edges. We match the schedule to your monitoring data.
