Photovoltaic installation: everything you need to know about IRPF relief

We're sure you're keen to find out all about IRPF deductions for solar panels, so we're going to dig into theme below! But first off, what is IRPF, and what does it have to do with the world of solar panels?

IRPF and solar panels

Personal income tax (Impuesto sobre la Renta de las Personas Físicas, IRPF) is a tax that individuals resident in Spain must pay to the State. It's levied on income earned over the course of a year (salaries, rents received, income from economic activities, etc.). And it takes each person's family and personal circumstances into account.

Percentage of tax relief

As part of the Plan for Recovery, Transformation and Resilience and in order to encourage the energy rehabilitation of homes and buildings (and therefore reduce non-renewable energy consumption by at least 30%), an IRPF rebate for solar panels of at least 20% has been established (In Catalonia this could be as much as 50%).

Who will be able to deduct?

All those who have installed photovoltaic solar panels in their home before 31st December 2023 can apply for IRPF relief.

Permits and requirements: IRPF and solar panels

Don't worry!

Our experts will handle the documents, be by your side at all times and take care of processing the IRPF relief for your solar panel installation.

Permits for solar panel installation

How is IRPF relief for solar panel installations applied?

  • The deduction isn't applied automatically once your solar panels are installed: it has to be reported on your personal income tax return for the year in question.

  • It's very important for you to have the invoice and proof of your investment.

  • The installation of solar panels must be demonstrated on the Energy Efficiency Certificates, one before and one after, which must show that the demand for cooling and heating of the house has been reduced by at least 7% after the installation.

  • This Energy Efficiency Certificate must be provided on two occasions: before and after the installation of the solar panels.

Depending on your photovoltaic installation, what percentages apply?

20% IRPF deduction for solar panels

40% IRPF deduction for solar panels

60% IRPF deduction for solar panels

Characteristics of the installation of solar panels in your single-family home, for a 20% deduction in IRPF, with a maximum annual base of 5000 euros (amount paid for the work completed):

  • A reduction of at least 7% of the demand for cooling and heating of the single-family dwelling after the work has been completed.
  • The panels must be installed before 31st December 2023.
  • The post-installation Energy Efficiency Certificate must be issued before 1st January 2024.

The advantages of installing solar panels

You pay less

The IRPF rebate for the installation of solar panels is applied to the total, i.e it's deducted from the tax payable. There are different percentages of deductions on your tax return for solar panels: 20%, 40%, 60%
On top of the savings on your electricity bill and the European subsidies and grants for solar panels, there's also a 20% rebate on the IRPF for your main residence. This also applies to any parking spaces or storage rooms that have been acquired alongside your main residence, as long as they are located in the same residential building and are not related to any economic activity.

You maximise your return on investment

When you combine the savings on your energy bill with the IRPF benefits when you install solar panels, the return on investment (ROI) improves significantly. Would you like to calculate your quota after installing solar panels at home?

You cut greenhouse gas emissions

Making the decision to install solar panels also means you contribute to reducing greenhouse gas emissions, supporting the creation of a healthier environment and furthering the energy transition.
Renewable energy is the future. And the IRPF rebate for solar panels can go a long way to helping you contribute to that!
