To install solar panels in residential properties in Portugal, the licensing process may vary depending on various conditions, but, in general, the installation of solar panels is considered a work of scant urban relevance, which means that, in most cases, it does not require authorization from the municipal council. Here are the main points to consider:
General Licensing
-
Exemption from Prior Urban Control (RJUE):
The installation of solar panels (or photovoltaic) on roofs or facades is classified as Work of Scant Urban Relevance (Art. 6-A, no. 1, i, of RJUE). Through this classification, the installation is exempt from licensing or prior communication to the municipal council. The exception applies only to classified properties or properties under classification (historical heritage) or in Protection Zones, where specific authorization may be required.
-
Prior Operation Communication (DGEG):
For Self-Consumption Production Units (UPAC) with installed capacity between 350 W and 30 kW, the procedure requires only a Prior Operation Communication to the General Directorate of Energy and Geology (DGEG), through the electronic counter. This is the only control required at the energy level, after installation.
-
Total Exemption (DGEG):
UPACs with installed capacity equal to or less than 350 W are exempt from any prior control by DGEG or external entity, simplifying installation to the maximum.
Special Considerations
-
Historic Buildings:
If the property is classified as historic, it may be necessary to obtain specific authorization for the installation of solar panels.
-
Condominiums (Horizontal Property):
If the installation is made on the roof (common part), current law (Art. 1421-A of the Civil Code, added by More Housing) allows any condominium owner to proceed with the installation, provided that the Condominium Owners’ Meeting does not object, by decision of a majority of two-thirds of the total value of the building.
Incentives and Benefits
-
Tax Incentives and Subsidies:
There are programs such as the Support Program for More Sustainable Buildings that offer co-participation for the installation of solar panels, helping to reduce the initial investment cost.
These steps ensure that the installation of solar panels is done in accordance with current legislation, promoting energy efficiency and environmental sustainability. It is always advisable to consult specialized professionals to ensure that all legal and technical requirements are met.
