Understanding the profile
Groupe E publishes photovoltaic solutions for housing, self-consumption, storage and local electricity sharing. The residential course describes a technical visit, handling of administrative procedures, installation, commissioning and advice on use. The group also offers calculation tools and offers linked to the purchase or sharing of excess energy.
For large areas, Groupe E Greenwatt presents a photovoltaic contracting formula from around 300 m²: the owner makes the area available while Greenwatt finances and operates the installation under a long-term contract. Such a formula does not compare like a classic purchase. Consideration should be given to plant ownership, energy price, indexation, maintenance responsibilities, duration and exit conditions.

For which projects is this profile relevant?
Homeowners in the group's service area, buildings studying electricity sharing and businesses with large roofs that could be purchased or operated under contract.
Prepare the project well
For a building or business, gather load curves, leases, meter diagrams and renovation projects. These documents determine whether individual self-consumption, a local community or contracting is worth studying. Ask for a note that separates the technical solution from the energy contract: participants, metering, billing, taxes, data, duration and tasks remaining with the owner must be understandable before any decision.
How to compare the offer
Separate the installation offer from the electricity supply, recovery or sharing services. The installation price is not enough to evaluate a model which also includes energy flows and recurring costs.
For contracting, build a comparison over the entire period: self-consumed energy, indexation, maintenance, insurance, rights to the roof, end of the contract and option to take over the installation.
