A photovoltaic installation is more than laying panels. It's designed, sized, integrated. Our engineering office and our field teams are one — for installations that really produce what we promised.
Most solar installers sell you panels. We sell you electricity production over 25 years. The difference? We measure your actual solar irradiation, simulate shadows from neighbouring trees, calculate the hourly consumption curve for each month — and only propose an installation if it's profitable.
If the project doesn't add up, we tell you. Our compensation isn't based on volume sold, but on our customers' satisfaction over ten years.
Our installations adapt to the building's nature, the desired power and the administrative framework. Here are the three main families we serve in French-speaking Switzerland.
Installations from 4 to 15 kWc. Roof-integrated or surface-mounted. Optional battery for maximum autonomy. Guaranteed self-consumption 50–70%.
Self-consumption groupings (RCP/ZEV). Production split between owners. Full administrative support with the grid operator.
Installations from 30 to 500+ kWc on flat roof. Self-consumption maximised during the day. Improvement of ESG balance and energy security.
In French-speaking Switzerland, payback is between 8 and 12 years, depending on the installation, self-consumption and subsidies obtained. Panels are warranted 25–30 years, leaving 15–20 years of net gain.
Without a battery, your installation shuts down automatically (safety requirement). With a hybrid battery, you can activate islanded operation and supply critical circuits.
Yes. French-speaking Switzerland has a solar irradiation profile equivalent to southern Germany. Panels produce even with clouds and snow (albedo effect actually boosts production).
For most roof integrations, a simple notification to your municipality is enough. We handle all procedures.
We come to you free of charge and without obligation. One hour is enough to draw a first precise picture of your solar potential.
