Our core service is solar panel cleaning, complemented by roof & facade cleaning, inspections and thermography. Clear starting prices — every project receives a fixed quote after a free initial assessment.

Factors that play a role
Travel costs are calculated from Geraardsbergen. Within 15 km they are included.
A light layer of dust versus stubborn moss, bird droppings or industrial residue determines cleaning time.
Flat roofs and solar farms are cleaned faster and more safely than steep installations.
A one-off cleaning costs more per visit. Recurring maintenance earns a discount.
