We use tap water for gentle cleaning that preserves the performance of your solar installations.
Entrust us with the regular maintenance of your panels to ensure they work at their best, even after 20 years of use.
This environmentally-friendly process prevents the build-up of dirt and residues, maintaining the value of your panels and ensuring consistent performance. Our pure water washing method ensures effective, streak-free cleaning of surfaces and frames, for optimised solar performance.
We carefully remove dust, leaves and other debris, promoting maximum solar absorption. Our manual approach uses a soft sponge and a soft bristle brush for precise, risk-free cleaning. In the event of persistent dirt, our pure water solution, applied with a soft cloth, ensures thorough cleaning while preserving the integrity of your installations.
Improving energy performance : Regular cleaning with pure water can significantly increase the energy yield of your panels, ensuring optimum energy production all year round.
Careful and efficient cleaning: Our experts use meticulous cleaning techniques to avoid thermal shock and micro-cracks, thereby preserving the energy efficiency of your installations. Using demineralised tap water rather than chemicals protects the environment and the integrity of your panels.
The underestimated importance of cleaning : In a fast-growing sector, the maintenance of solar panels is crucial. Without proper cleaning, panels can lose up to 50 % of their efficiency in five years. Dust, pollen, air pollution and soot deposits considerably reduce their performance. For maximum efficiency, we recommend cleaning your photovoltaic system every two years.
For solar panel cleaning, new customers must make payment before or on the day of the service. For our Nettoyage Express customers, we send an invoice in writing or by e-mail, payable within 30 days. Payment can be made in cash on site or by e-banking before the service.
We recommend that you clean your solar panels at least twice a year to ensure that your photovoltaic system works at its best.
Contrary to popular belief, rain is not enough to clean solar panels properly. It can leave deposits of dirt and dust that reduce the efficiency of the panels.
