Technical design report for building permits with Municipalities. Mandatory documentation for some municipalities, for the installation of a photovoltaic system with a power of less than 10 kW signed by a competent qualified technician, according to the Low Voltage Electrotechnical Regulation (REBT).
For legalization in the autonomous communities, and with energy supply companies, additional procedures are also required.
If the planned power exceeds 10 kW, even if the connection is made in LV, it will be necessary to prepare a technical project drafted and signed by a competent qualified technician..
Technical design report. Mandatory documentation for all municipalities, for the installation of a photovoltaic system with a power of less than 10 kW, signed by a competent qualified technician, according to the Low Voltage Electrotechnical Regulations, in case the connection is in low voltage.
For legalization in the autonomous communities, and the energy supply companies, it is also necessary, in addition to other procedures.
If the expected power is greater than 10 kW, even if the connection is made in LV, it will be mandatory to carry out a technical project drafted, signed by a competent qualified technician and endorsed by an official professional association.
A building permit must be requested from the Municipality for self-consumption photovoltaic installations. Always following municipal regulations.
According to the power, the Municipality will determine if a simple declaration of responsibility or technical report is sufficient.
The Royal Decree 244/2019 which regulates the administrative, technical, and economic conditions of self-consumption of electrical energy, regulates the modalities of self-consumption of electrical energy defined in article 9 of Law 24/2013, of December 26, of the Electrical Sector.
The obligation requiring a technical design report applies to the owner of the low voltage electrical installation or their legal representative, and the authorized installer.
The necessary documentation in the design of the installation will depend on the type of grid connection to be used and the expected power for the installation.
If the connection is to be made in low voltage (LV, up to 1 kV) and the power of the installation is expected to be equal to or less than 10 kW, it will be sufficient to have a Technical Design report prepared by an authorized installation company. This report must include at least the contents reflected in the ITC-BT-04 of the Low Voltage Electrotechnical Regulations.
Both the report and the project must contain all the technical information and documentation of the installation: sizing, equipment and their characteristics, materials used, warranties, maintenance needs, etc.
The provisions of this Royal Decree apply to installations and subjects covered by any of the self-consumption modalities defined in article 9 of Law 24/2013, of December 26, of the Electrical Sector.
Self-consumption installations without excess power of any capacity are exempt from requesting access and connection permits. Therefore, these types of installations are also exempt from presenting guarantees and warranties for the connection.
The anti-backflow system of the produced current is mandatory for self-consumption installations without excess power since it will prevent current from being injected into the distribution and transportation network.
Legalization is also important to access the subsidies that administrations may offer. These incentives can cover between 40% and 90% of the initial investment. There are also aids for electric vehicle chargers, as long as they are accompanied by a photovoltaic installation.
Remember that failure to legalize your photovoltaic installation may result in fines from the energy distributor or the local or regional government.
