Our approach

More than an installer, an energy partner.

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.

For whom

Private individuals, businesses, co-ownerships: one expertise, three contexts.

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.

🏡 Single-family houses

Installations from 4 to 15 kWc. Roof-integrated or surface-mounted. Optional battery for maximum autonomy. Guaranteed self-consumption 50–70%.

🏢 Apartment buildings & co-ownerships

Self-consumption groupings (RCP/ZEV). Production split between owners. Full administrative support with the grid operator.

🏭 Businesses & industry

Installations from 30 to 500+ kWc on flat roof. Self-consumption maximised during the day. Improvement of ESG balance and energy security.

Our method

From visit to monitoring: a chain with no weak link.

  1. 01.Free technical visit — On-site measurement, roof survey, electrical panel assessment, 12-month consumption analysis.
  2. 02.Detailed study & quote — Production simulation with PVSyst, cantonal and federal subsidy calculation, detailed quote within 15 days.
  3. 03.Administrative procedures — Building permit, grid operator notification, Pronovo subsidy file. All handled in-house.
  4. 04.Installation — 2 to 5 day site work. In-house teams, OIBT electricians, site manager on location. Safety, cleanliness, respect for your home.
  5. 05.Commissioning & monitoring — Real-time remote monitoring, annual production report, 5-year workmanship warranty.
Frequently asked questions — photovoltaics

Everything you wanted to know before the visit.

How long to break even?

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.

What happens during a power outage?

Without a battery, your installation shuts down automatically (safety requirement). With a hybrid battery, you can activate islanded operation and supply critical circuits.

Do panels work in winter?

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).

Do I need a building permit?

For most roof integrations, a simple notification to your municipality is enough. We handle all procedures.

Ready to calculate?

Your roof deserves better than a rough estimate.

We come to you free of charge and without obligation. One hour is enough to draw a first precise picture of your solar potential.
