Sharing your solar electricity with your neighbors: RCPv and CEL explained simply

A solar installation rarely produces exactly what the building consumes at the same moment. The surplus goes to the grid, bought back at a rate that is often disappointing. Since 2026, two frameworks let you do better: sell that electricity to neighbors, at a price agreed between you, rather than to the grid. They are called the self-consumption community (RCPv) and the local electricity community (CEL), and they are not meant for the same situations.

RCPv: sharing within the building, through private lines

An RCPv links the producer and the consumers through the private lines of the building or the plot. The solar electricity does not travel over the public grid: it goes from the roof to the apartments through the internal wiring.

Direct consequence: no grid-use fees on the shared kilowatt-hours. It is the natural framework for an apartment building with a single rooftop installation, for a condominium association, or for neighboring buildings connected together.

CEL: sharing within the neighborhood, through the public grid

The CEL, in force since the beginning of 2026, widens the circle: producers and consumers in the same area share their electricity through the public grid. No more need for shared lines, being within the perimeter is enough.

Shared kilowatt-hours there pay a grid-use fee, but a reduced one: a 40% discount when the current stays at the same grid level, 20% if it changes level. It is the framework for neighbors across a neighborhood, for the producer supplying the house across the street, or for a village getting organized.

How to choose

• Same building or same plot, shared lines possible: RCPv, sharing with no grid-use fee at all.
• Neighbors separated by public land: CEL, sharing through the grid at a reduced fee.

The two frameworks also combine very well: a building with an RCPv can sell its remaining surplus to the neighborhood CEL.

What SOLARSPLIT Community Connect brings

Forming a community, allocating kilowatt-hours among participants, billing each one their fair share: it is recurring administration, and it is precisely what SOLARSPLIT Community Connect automates, from forming the community to billing each participant.
