🏘️ Can I share solar power with neighbours or join an energy community in Spain?

The short answer

Energy sharing lets households use power produced by a shared installation, a neighbour or a community project. Whether and how it works depends on the national rules.

📜 The rules in Spain

Energy sharing and communities

Collective self-consumption (autoconsumo colectivo, Real Decreto 244/2019) lets several consumers share one installation, for example a building's solar panels. All participants sign a sharing agreement (coeficientes de reparto) and send it to the distributor, directly or through their supplier.

  • The installation must be nearby: behind the same transformer, on the same cadastral reference, or within 500 m. Solar or wind plants up to 5 MW connected through the grid may be up to 5,000 m away (RD 244/2019, as amended in March 2026). (boe.es)
  • A comunidad de propietarios can be the owner of a shared installation. (miteco.gob.es)
  • Renewable energy communities (Real Decreto-ley 23/2020) are open, voluntary entities controlled by their members – citizens, SMEs or local authorities – that produce, use, store, share or sell energy for local benefit rather than profit. (idae.es)

❓ Questions

Do I have to own solar panels?

No. In many schemes you can take part as a member or user without owning an installation.

Does my supplier stay the same?

Usually yes. The shared power is counted first and your supplier provides the rest.

Who registers the sharing?

Normally the grid operator or the body named on this page. Ask them before you start.
