Solar Supervising Energy Communities

Supervised Self-consumption Solution

Currently, Collective Self-consumption is one of the most interesting energy models. It involves great economic and energy savings by allowing several consumers to share the same photovoltaic installation. It is open, therefore, to blocks of apartments, industrial estates and energy communities.

To enjoy a collective self-consumption installation there are certain requirements:

  • Mandatory to reach an agreement between all or part (one third in the communities of neighbors) of the owners of the houses or buildings through a contract.
  • Meet ONE of these three requirements:
    1. All of them must be connected to the same transformation center that makes the low voltage distribution.
    2. Maximum 500 m. distance between the self-consumer and the generation meter.
    3. The installation and the self-consumers must be in the same cadastral reference.

There are two modalities, being the public network modality the one we will see in depth:

  • Public grid: This is the most common. The photovoltaic plant connects to the low voltage grid through a bi-directional meter, so the distributor and marketer compensate the self-consumers through this public grid.
  • Indoor Grid: The photovoltaic production is distributed directly to each of the internal grids of the self-consumers. This requires certain conditions that make it more suitable for industrial installations.

To make shared self-consumption viable and useful, simple and transparent solutions are necessary, that is why we recommend using CcM's "supervised" solution with a system that allows to show each member their consumption and percentage of generation in real time, which is necessary to:

  • To verify every day the performance of the installation, the expected savings and the committed profitability.
  • To have very practical and easy-to-interpret information to be able to adjust consumption habits, optimize savings and quantify their contribution to improving the environment.
  • The manager can modify coefficients, calculate compensations, manage user registrations and cancellations, as well as apply and modify the electricity tariffs of each consumer.

Software

Shared Self-consumption CcM

Hardware

CcMaster

Concentrator, datalogger and gateway of the collective consumption plant. It reads our meters natively and includes the protocols to read all the PV inverters, meters or network analyzers to obtain the TOTAL generation and consumption data, as well as the individual consumption data of the members of the collective solar installation. It communicates via NBIoT and/or 2G, which allows to ensure its network coverage at any point, even in a parking -4 plant.

clicMONITOR Meters

Analyzers or "Smart Meter" meters. They measure the energy flowing through each phase of a single-phase and two-phase (Ccm2) or three-phase (Ccm4) magnet.

CcMs Meters:
Network analyzers (63 A).
Measuring accuracy B2.
Electrical category III.
Phase and total measurements.
Bidirectional.
Retrofit.
Self-powered.

Our CcMaster device can read the generation meter or a network analyzer (R.A.) to obtain the TOTAL energy generated, read it directly from the PV inverters; or an R.A. to measure the TOTAL energy consumed from the network.

All data are concentrated in the CcMaster and sent from a single computer.

In these two examples of collective consumption, the virtual plants of the community members are generated in the cloud through our software, unlike the previous example where all the data is acquired at the same point.
