RD 244 Collective self-consumption

Subscription model

Collective self-consumption with no building work

Under collective self-consumption, regulated by RD 244/2019 (Spain's self-consumption decree), several consumers share the output of a single solar installation without needing to install panels on their own building.

Monthly subscription

You contract a capacity in kW (1 kW minimum). You pay a fixed monthly fee of €12/kW, independent of actual production.

Energy to the grid

The La Mossota plant feeds solar electricity into the grid. The distribution company applies an allocation coefficient to your meter (CUPS).

Deduction on your bill

The energy allocated to you is deducted directly from your electricity bill as self-consumption. No batteries, no building work on your property.

Full transparency

Log in to the Cercle Solar portal to see production in real time, your accumulated savings and your monthly statements.

Legal framework: Real Decreto 244/2019 (collective self-consumption with or without surplus). The monthly fee replaces the cost of the solar energy consumed; it does not include regulated grid charges. Actual savings depend on your tariff, the plant's output and your assigned allocation coefficient.
