Photovoltaic installations in communities of owners
Are you thinking about installing solar panels for your home, but you have doubts because you live in a community of owners? Would you like more information about what it means to install solar panels in a community of neighbors?
From ATES we advise you on the details to take into account, beyond “how much does it cost to put solar panels in a house”. In this article you will find the necessary information to compare and decide with criteria, to resolve your doubts about whether it is worth putting solar panels in your home.
In addition, we can advise you in a personalized way and without obligation, through our email address comercial@ates.es
The first thing, apart from contacting a specialized company, is to have certain basic knowledge to be able to analyze the proposals that are presented to you, and that you can see if it is profitable for you to put solar panels. If you haven’t already done so, we invite you to read our Introductory guide to photovoltaic self-consumption
1. Possibilities for solar energy installations in Communities of Owners.
If you are thinking of putting solar panels for communities or solar panels in a community of neighbors, keep reading.
Communities of Owners usually have a clear flat roof, which makes it easier to install photovoltaic panels, that is, to install solar panels on a community roof. When a self-consumption photovoltaic installation is carried out in a community, it is usually done with two intentions:
a) Provide clean renewable energy from solar sources for general services such as lifts and lighting.
b) Use it directly in the homes of the owners.
In the first case it will be a conventional installation, and it must be dimensioned in the same way. But in the second case there is, since 2019, the option of carrying out shared self-consumption.
2. Shared self-consumption of photovoltaic solar energy.
Thanks to RD 244/ 2019 we can share the renewable solar energy generated by a self-consumption photovoltaic installation between different consumers, provided that any of these conditions is met in the consumers:
- Be from the same building.
- Be within a radius of 500 meters from the photovoltaic installation.
- Share the last 14 digits of the cadastral reference.
The operation of shared self-consumption is simple, it is a single generation installation, large and capable of supplying the needs of the co-owners. In it, an independent meter is installed that will have a code assigned to the distribution company, in the same way as the meters of the supplies with which it shares renewable solar energy.
In order to share photovoltaic energy, a sharing agreement must be signed between the different owners. In each counter code, the percentage that we want to assign to it of the total production must be indicated. The percentages of distribution must be agreed between the users of the installation. From Ates Energy Solutions we recommend analyzing the specific needs of each one.
With the distribution agreement drafted, it is sent to the distribution company in the area. The distributor will be in charge of calculating and communicating to our marketer the amount of energy that corresponds to us. As a requirement, the meters must be digital, since it is necessary to be able to compare the energy produced and consumed hour by hour.
It is also important to bear in mind that a percentage may be assigned, whichever is necessary, to the accountant of the general services of the community.
3. Economic advantages of having a shared self-consumption solar panel installation.
All photovoltaic installations for self-consumption end up paying for themselves, sooner or later. But in addition to the economic savings generated, the price we have paid for the installation of solar panels in a community of neighbors is very important. This entails:
The main components of any installation are the solar panels and the inverter. For the panels we will put more or less depending on the power we want. On the other hand, the inverter will always be necessary. Their cost usually represents the largest part of the budget.
With a shared self-consumption installation, we will have a single inverter for all co-owners. In this way, a large part of the total cost that corresponds to us according to our distribution coefficient is shared. Thus, the amount to be paid is notably reduced for each kW installed. In addition, if necessary, any repair or breakdown may also be paid for by all.
4. Disadvantages of having a shared self-consumption photovoltaic installation.
We only find a disadvantage in shared self-consumption. In certain communities the roofs have little space available for the number of homes that comprise them. This characteristic results in in the distribution agreement the power for homes being limited below the necessary optimum. Even so, we are always going to get a very competent price per installed kW. In this way, the self-consumption solar installation pays for itself in a short period of time.
5. Requirements to approve the installation of renewable energies in a Community of Owners or neighbors.
When installing solar panels in a community of Owners, they must be approved in a meeting. Also, in the distribution agreement must be recorded in its corresponding minutes.
For a photovoltaic installation that provides solar energy only to the general services of the building, the approval of a third of the owners will be sufficient. If you want to provide a contribution to homes, it must be approved by a simple majority. To avoid possible complications in the future, it is always advisable to obtain approval by a simple majority.
