Solar panel cleaning in Montlhéry (91310)
Solar panels, photovoltaic or thermal, on roofs, carports or the ground. Clean water and a soft brush, with no harsh products and no pressure washing.
Solar panel cleaning is not on the list of Services à la Personne activities: it deals with energy-generating equipment, wherever it is mounted. No tax credit applies to this service.
Send a photo: for many jobs that is all we need to prepare the quote, with no visit.
Washing is done with clean water and a soft brush on a pole. No harsh products, no pressure washing, no squeegee: the glass on a panel carries a surface treatment that a household cleaner or too strong a jet can damage, and a scratched module stays scratched. The work is best done early in the morning or at the end of the day, on cold panels.
Pricing is per panel, once the number of modules, the pitch and the access are known. A ground or carport array is quicker to work through than a steep roof at first-floor height, for the same number of modules. The quote is free, and a photo of the array is often enough to prepare it.
What is different in Montlhéry
The old centre around the tower is full of small-pane windows, cleaned one pane at a time.
Small-pane windows hold what a single large sheet lets run off. Dust thrown up by the traffic, and the rain that drives it back down, settle into every corner of every glazing bar — the place a cloth reaches worst. It builds slowly, and in the end it sets hard.
Terraced town houses with wooden frames and glazing bars in the old centre, more recent detached houses around it. Two methods in one commune, and two very different amounts of time on site: in the old centre you count panes, not square metres.
