Collective self-consumption lets several neighbours share a single installation on the building roof. We handle the project, the owners’ meeting, the split by coefficients and the paperwork with the grid operator.

Split by coefficients

Each neighbour gets the share of production the community agrees on.

Owners’ meeting support

We prepare the documentation and the proposal for the vote.

Shared charging

Common charging infrastructure with individual metering.

In-house maintenance

Salaried technicians for the shared installation, no subcontractors.

FAQ

What you usually ask.

Do all neighbours have to take part?

No. Those who want can join and the rest can come in later. The split adjusts to who participates.

Who maintains the shared installation?

We define it with the community. We offer a maintenance contract with our own technicians.

How is the saving split?

By coefficients agreed at the meeting. They can be fixed or dynamic depending on each home’s consumption.

What rules govern collective self-consumption?

RD 244/2019, with the proximity distance through the grid extended to 5 km (RDL 7/2026). It lets a single installation be shared among several nearby consumers or those with the same cadastral reference. We verify your building qualifies before proposing anything.

How long does the whole process take?

The slowest part is usually the owners’ meeting, not the work. Once approved, the installation is done in a few days and the paperwork with the grid operator takes a few weeks.
