Our offer for businesses
A complete energy answer for your business
Offices, shops, workshops, SMEs or public buildings: every activity has a different consumption profile. We combine the right levers — generation, mobility, heat, storage — into a single project, studied and priced on your real data.
Solar PV on roofs & canopies
Solar plant sized to your load curve to self-consume during the day, when your business is running. Flat roofs, steel decking, car-park canopies: we adapt the structure to the building.
Fleet charging stations
Charging infrastructure for company and visitor vehicles: charge management, supervision, billing and pairing with solar to drive on the energy generated on site.
Commercial heat pump
High-performance heating and cooling for offices and commercial premises. Air-to-water or air-to-air heat pumps sized to replace oil or gas and lower the bill for good.
Storage & energy management
Storage batteries and a management system to smooth peaks, secure sensitive uses and maximise self-consumption at times when you are not generating.
Monitoring & supervision
Real-time tracking of generation, consumption and charging stations. Dashboards, alerts and reporting to manage your costs and prove your savings.
Maintenance contract
Preventive maintenance, periodic checks and priority interventions. A clear contract that guarantees the output of your installations over time.
Our project method
From the energy study to maintenance
-
Energy study & audit
Analysis of your consumption, your load profile, your roof and your uses (fleet, heat, processes). We identify the most profitable levers and the subsidies you can claim.
-
Design & global quote
A single technical and financial proposal: solar, charging stations, heat pump, storage and monitoring priced together, with estimated generation, savings and return on investment per item.
-
Project management & installation
A project manager handles the procedures, the schedule and the teams. Coordination of the trades, connections to standards and a worksite organised to limit disruption to your business.
-
Commissioning & maintenance
Start-up, monitoring configuration and training for your teams. Then performance follow-up and a maintenance contract to guarantee output over the long term.

Study & maintenance
Professional energy audit & maintenance contract
It all starts with a professional energy audit: we cross-reference your bills, your load curve and your building to build a costed action plan. Once the installations are live, the maintenance contract takes over to secure output and availability throughout the project’s lifetime.
- Energy audit on your real data, not on averages
- Costed action plan: generation, mobility, heat, storage
- Maintenance contract: preventive, checks and priority interventions

Can your building generate and consume better?
A professional energy study proves it with figures: solar potential, charging needs, savings reserve and subsidies, with no commitment.
Frequently asked questions
Energy solutions for businesses
What types of business is this offer for?
Any professional or commercial building: offices, shops, workshops, industrial SMEs, but also public bodies and public buildings. We adapt the solution to your consumption profile and your constraints, whether you own or hold a long-term lease.
Why go through a single multi-trade contact?
Because a professional energy project often combines several trades — solar, charging stations, heat pump, storage, monitoring. A single partner means a coherent study, a global quote, a project manager who coordinates everything and one contact for any question or maintenance. You save time and avoid blind spots between providers.
What does the professional energy study involve?
We analyse your bills and your load curve, examine your roof, your uses (fleet, heating, processes) and your future needs. You receive a costed action plan, item by item, with estimated generation, expected savings, the return on investment and the subsidies you can claim. It is the basis for an informed decision.
Can we pair solar with charging our fleet?
Yes, and it is often one of the most profitable levers. By managing the charging of your vehicles around the day’s solar generation, you drive on the energy produced on site and sharply reduce the cost per kilometre. Monitoring also enables supervision and billing of charging sessions.
What tax benefits are there for a professional investment?
As a VAT-registered business, your company generally recovers the VAT on the investment, and the installation can be depreciated for accounting purposes. Depending on the region and the nature of the project, grants and deductions may apply. Our study factors these in and we offer professional financing solutions adapted to your cash flow.
