Drone high-access cleaning in Le Havre

Cleaning drones project water and treatment solutions at high pressure onto high surfaces, without scaffolding, lift platforms or rope access: roof moss removal, facade cleaning, industrial cladding, soiled photovoltaic panels, glass canopies and steel structures. Fed from the ground through a hose connected to a pumping station, the drone treats 300 to 500 m² per hour depending on the surface — two to four times faster than traditional access methods, at a markedly lower cost as soon as the height exceeds two storeys.

We match the treatment to the substrate: low-pressure rinsing with deionised water for solar panels (no streaks), certified moss killer for roofs, appropriate detergents for cladding and render. The gain is not merely cosmetic: clean panels recover several percent of output, a de-mossed roof lasts longer, maintained cladding keeps its manufacturer warranty.

Common use cases

The local context in Le Havre

Le Havre concentrates first-rank sensitive zones: the HAROPA port estate, several upper-tier Seveso industrial sites in the port-industrial zone (refining, chemicals) that cannot be overflown without the operator's agreement, and Le Havre-Octeville airport to the north. The Paluel nuclear plant and the Normandy bridge nearby add further planning considerations.

That industrial profile is also the market's source: inspection of cranes, warehouse roofs and sea walls, monitoring of port extension works and offshore wind logistics (maintenance base for the Fécamp wind farm), plus Auguste Perret's UNESCO-listed rebuilt centre and the Alabaster Coast cliffs for tourism imagery.

Applicable regulations

Cleaning drones are heavy machines (10 to 25 kg with the loaded hose): they fall outside the open category for most jobs and operate in the specific category, under a scenario or an operational authorisation with SORA risk assessment, especially as they often fly in built-up areas right next to buildings. The ground area is always cordoned off and closed to the public during treatment (risk of falling water and spray). Environmental rules also apply: approved treatment products, controlled recovery or infiltration of runoff depending on the site, no direct discharge of biocides into storm drains. AlphaTango registration, pilot trained in tethered flight with payload, coordination with the building operator.

Frequently asked questions

Does drone cleaning damage tiles or panels?

No: pressure is adjusted to the substrate (low pressure on tiles and panels, never destructive high pressure) and the drone never touches the surface — unlike foot traffic, which cracks tiles.

What output gain can be expected after solar panel cleaning?

Depending on soiling (dust, pollen, bird droppings, agricultural or industrial deposits), observed gains range from 3 to 15% of output. A thermal inspection can be combined with cleaning to detect faulty modules.

Do water or power need to be cut during the work?

We bring our own water supply (tank and pumping station). For photovoltaic panels, shutting down the inverters during washing is recommended; we coordinate this with your plant operator.

Can this service be flown anywhere in Le Havre?

Almost: Emprises du Grand Port maritime et sites Seveso de la zone industrialo-portuaire; Aéroport du Havre-Octeville; Pont de Normandie (ouvrage sensible). Depending on the exact location, the pilot picks the right framework (open or specific category) and files the required declarations — included in the quote.
