Our catchment area for the cleaning of photovoltaics extends from the North See to Lake Constance. There will be no surcharges for overnight stays and travel. We usually start the cleaning within three working days after procurement and finish the work short-term. Your photovoltaic or solar system is cleaned solely on the basis of ultrapure water – without chemicals and/or cleaning agents – to maintain the manufacturer warranty of the modules.
Ask your respective WERTHMANN® partner in your region for our loyalty bonus.
We are looking forward to working for you and already today we assure you diligent execution of the cleaning work.
