What permits do you need to install solar panels on your home?

First, in most cases, it's mandatory to submit a prior notification or minor works permit to the town hall. Although many photovoltaic installations don't require a major works permit, they must still be properly notified, especially if they affect the building's roof.

Second, a technical project or technical report, signed by an authorized installer, is required. This document guarantees that the installation complies with current electrical regulations and the Building Technical Code. At Immosegur, we always recommend working with certified professionals to ensure the project's viability from the outset.

In apartment buildings, community approval is also required, usually by a simple majority if the installation is for individual use on common elements, or by a qualified majority if it significantly affects the building's structure or aesthetics. Another important point is the legalization of the installation with the regional government, which includes industrial registration and notification to the electricity distribution company. This step is essential to be able to offset surplus energy on the electricity bill.

It's also advisable to check if the property is in an area with urban planning or heritage protection, as in some cases there may be additional aesthetic or technical limitations.

Finally, don't forget the subsidies and tax deductions, which in Catalonia can significantly reduce the installation cost, although they usually require proper administrative procedures. Installing solar panels is becoming increasingly simple, but it requires planning and regulatory compliance. At Immosegur, we assist homeowners so that these types of improvements not only increase energy efficiency but also the value of their property.
