- Scheduling based on on-site conditions
Assessment of dirt build-up and accessHow we work
Dust, pollen and bird droppings can build up on the modules. We first assess whether cleaning is worthwhile. The choice of equipment, water and working conditions takes the manufacturer’s recommendations into account. Roof access is examined before the service is confirmed.
What to tell us before the quote
Tell us your municipality, the type of building and an estimate of the surfaces. If you don’t know the dimensions, simply describe the situation. Mention the height, access, any furniture and time constraints. This information helps us prepare a suitable proposal.
Do you represent a property manager (syndic), an agency or a business? Mention the number of sites and who coordinates access. For regular cleaning, we define the visits and scope together. The form does not automatically book any date.
Limits matter too.
Any gain in output depends on many factors and cannot be guaranteed. Cleaning does not replace an electrical inspection, a repair or follow-up by your installer.
How is the price set?
The quote depends on the amount of surface, how dirty it is, the method required and the means of access. The frequency and combining several services can also change the organisation. We prefer to clarify these points rather than quote you a price that doesn’t match your building.
Before you agree, check the surfaces included, any options and the practical arrangements. If your needs change, let us know before the work so the scope can be adjusted. That way you keep a clear view of what is planned.
Deciding whether cleaning is worthwhile
Having panels doesn’t mean cleaning has to be scheduled at a fixed frequency. Exposure, tilt, nearby trees and the type of deposits can all change what’s needed. Describe what you can see from an accessible spot: even dust, localised marks or persistent dirt. There’s no need to climb onto the roof to prepare a request. If you have documents from the manufacturer or installer, they can help clarify the maintenance conditions. A photo taken from the ground can also add to the description when you talk directly with the team.
Output and maintenance: two different questions
A change in output alone doesn’t mean the panels are dirty. Weather conditions, shading and how the installation is working must be considered by the appropriate professionals. Cleaning deals with deposits on the surface; it doesn’t repair a module, a cable or an inverter. If your installation shows a fault, contact your installer before scheduling a maintenance visit. We avoid promising figures: a percentage announced without knowing the starting condition doesn’t accurately describe the result you can expect.
Preparing access and scope
Tell us the approximate number of panels, where they are and the type of building. An installation on an accessible annexe doesn’t have the same constraints as an array on a high roof. Mention visible obstacles, available access and any co-ownership rules. Feasibility, the means required and the working conditions must be confirmed before the appointment. If several buildings are involved, list them separately in your request rather than just giving a total number of modules. This preparation lets us draw up a quote that matches the job actually planned.
After the visit
Keep a note of the agreed scope and any observations shared at the end of the job. To monitor your installation, rely on your installer’s tools and advice, without automatically putting every change in output down to the cleaning. If deposits come back quickly, tell us what they are and where: this can help plan future maintenance. A new visit should meet an identified need, not a general promise of performance.
