Solar panels
An installation that makes the most of the usable area of your roof, with sizing discussed with you.
We make use of your roof
We install the power your roof can really accommodate, then work on your self-consumption so that as much of this production as possible serves you directly rather than being sold back to the grid. The simulator tells you what share of your consumption the installation covers.
On-roof mounting
We mount the panels on top of the existing roof covering: it is the most reliable and most economical solution, and it preserves the waterproofing of your roof. It suits the vast majority of tiled or sheet-metal roofs.
What the equipment guarantees
The panels carry a 25-year performance warranty, with degradation of around 0.5% per year. An installation fitted today will still produce close to 90% of its power in twenty years.
A solar project also starts in your electrical panel.
Before going up on your roof, we look at what is happening below it.
- The condition and capacity of the electrical panel
- The protections required
- The connection of the inverter
- Compatibility with the existing installation
- The grid operator's requirements
- Safety and OIBT compliance
This is where our experience of OIBT inspection makes the difference: we anticipate these points before the work starts, not after.
Every solar project starts on the roof. The good ones also start at the electrical panel.

Frequently asked questions
- Does the roof need to be redone first?
- If the roof covering is more than thirty years old, yes: dismantling and refitting an installation costs more than planning ahead. The technical visit will tell you plainly.
- What happens in a hailstorm?
- The panels are tested to withstand 25 mm hailstones at 80 km/h. They are also covered by your building insurance, which must be told about the installation.
- What if I move?
- The installation is attached to the building and adds to its value. It is passed on with the sale, warranties included.
