A collective self-consumption installation is the sum of "n" individual installations that share a series of common infrastructures: a single project, a single wiring, a single inverter, a single legalization and processing.
For this reason, it will be necessary to sign a sharing agreement between all participants in the collective self-consumption facility that will establish what % of the facility each participant has.
From here we must understand that sharing energy is a virtual phenomenon in which we do not really know where the electrons physically go.
For this reason, in a collective self-consumption installation it will be necessary to install a generation meter that will read and inform the distribution company of all the energy generated.
The distribution company will apply the distribution coefficients of the agreement and will allocate to each participant the corresponding part of generation. From here it will compare the generation with the consumption read by the consumption meters of each participant and will make the corresponding balance to end up billing each one for the difference between their consumption and their generation, and in case this difference is less than 0 applying the corresponding surpluses.
Currently the maximum straight line distance in the orthogonal plane between the generation meter and the consumption meter is 2 km.
Energy can be shared in both LV and MV.
No. You can share a facility with your neighbours', and therefore you will share all the energy generated (self-consumed and surplus), but you cannot share only your surplus.
The roofs of the communities are not for the exclusive use of the person who lives on the highest floor, but belong to the community of neighbors, therefore according to the Catalan civil code, you will have to ask the community for permission if you want to put a solar installation for individual use as if it were a community installation.
To request permission, it is necessary to convene the community meeting and state on the agenda that you want to request permission to install solar panels.
At the next meeting, the community board must approve the permit to carry out the solar installation by a simple majority of those present.
