Formalities for the legalization of the installation of photovoltaic panels
To legalize and install a photovoltaic panel installation, three main steps are required:
- Obtain permission from the local council to carry out the work.
- Registering the installation with the Generalitat as an electricity generator.
- To process the sale of energy with the utility company.
For the first step, and depending on the town hall we are in, there are two main steps to carry out the work at height legally:
- Communication or “assabentat”.
- License for minor works.
In our experience, in most town halls a building permit is required and therefore a building project is requested in order to obtain the permit. This procedure can take a month or two and has a high cost in projects and taxes.
If the town hall allows the “Comunicado” or “assabentat” procedure, under the responsibility of the client and at a reduced cost, the works can begin.
The second step is to register with the Generalitat as electricity generators. Once this procedure has been completed, we will have the right to ask for the reduction of IBI from the town hall or to ask for the subsidies that they offer.
Installations of less than 15kW are legalized with a descriptive technical report and do not require the signature of an engineer.
Installations above 15kW will be legalized with an electrical project and an engineer’s signature will be required.
The third procedure is with the supply company, and with all the documentation generated afterwards, it is only a question of them accepting the kW compensation and making the discount with the kW delivered to the grid.
