Professional cleaning in La Hulpe
In La Hulpe as everywhere in Belgium, pollen, bird droppings and pollution settle on your panels all year round; tap water, for its part, leaves limescale deposits. We clean exclusively with reverse-osmosis water and soft rotating brushes, from the ground with a telescopic pole where the configuration allows, with harness and anchor points for roof work. From 9 EUR per panel on a recurring contract, one-off visit at 12 EUR per panel.
Every intervention is documented with before-and-after photos, so you can see the result and track the yield on your inverter. Businesses and private individuals, no minimum number of panels.
