Barcelona, a city located in a privileged latitude, has ideal geographical conditions for installing solar panels and taking advantage of solar energy. With a high solar radiation index of 3,031 hours of sunshine and a peak solar hour of 4.2, Barcelona offers a favorable environment for the generation of solar energy through solar panels.

The inhabitants of Barcelona have adopted solar energy as a sustainable option in their neighborhood community, and it is common to find solar panels installed on the roofs of buildings in neighborhoods such as Horta-Guinardó, La Bordeta or Gràcia, among other areas, which have joined progressively to solar self-consumption.

Likewise, Barcelona has a topography that provides excellent sun exposure, with few obstacles that could generate shadows on the solar panels. This characteristic makes it an optimal location for the installation of solar panels, which contributes to maximizing the efficiency and performance of solar systems in the generation of renewable energy.

Why install solar panels in Barcelona?

Solar energy allows consumers of different kinds to produce their own electricity, covering part of their electrical needs at a cost lower than what is usually paid to electricity marketers, and avoiding the CO2 emissions associated with traditional electricity generation.

Solar self-consumption is the ability of one or more consumers to generate, manage and consume energy on the same site or remotely, either with or without energy storage. Every kWh produced and self-consumed is 1 kWh less that we must buy from the electricity company, with the corresponding saving on the electricity bill.

Solar energy allows us to:

Save more than 50% on our electricity bill from day one.
Avoid rising electricity prices.
Get economic value out of the rooftops of our homes and buildings.
Reduce the carbon footprint associated with our daily lives.
Contribute to a cleaner and more responsible world.

Requirements for installing solar panels in Barcelona

These are the prerequisites for installing solar panels in the city of Barcelona:

Drafting of a technical report (installations up to 10 kW) or a technical project (installations over 10 kW or premises for public gatherings).
Request for a connection point to Endesa Distribution (only for projects over 15 kW).
Processing of a prior works notification at Barcelona City Council.
Opening of a work centre and preparation of a health and safety plan.

Once the installation is complete, the following will be required:

Prior inspection by an Accredited Control Body (only for projects over 15 kW or premises for public gatherings).
Signing of the technical access contract with Endesa Distribution (only for projects over 15 kW).
Registration in the Register of Industrial Safety Technical Installations (RITSIC).
Registration in the Catalan Self-Consumption Register (RAC).

If you want to install solar panels in Barcelona, it is highly recommended to hire a comprehensive service from a specialised solar energy company that includes engineering, prior processing, materials supply, installation, legalisation and management of tax incentives and/or grants.

Residential communities in Barcelona

Many residential communities in Barcelona have already opted for shared self-consumption. If you want to install solar panels in your community you will need:

Owners' agreement: Approval from a majority of the owner-residents of the community is required, which must be reflected in a legal document, such as the minutes of the owners' meeting. In the case of rented homes, it is necessary to consult with the property owners.

Grants and tax incentives available in Barcelona

Currently, there are different lines of incentives to help finance a solar panel installation in the city of Barcelona:

Grants from the Self-consumption and Storage Incentive Programme of the ICAEN.
Discount of 50% on the Property Tax (IBI) for 3 years at Barcelona City Council.
Discount of 50% on the Business Activities Tax (IAE) for 3 years in Barcelona city — specific for businesses and companies.
Discount of up to 95% on the ICIO (Tax on Constructions, Installations and Works) for projects that integrate renewables (RDL 7/2026).
Deduction of the IRPF of up to 60% under the new Royal Decree-Law 7/2026, combining photovoltaics with heat pumps. More information on our grants and subsidies page.
Reduced VAT of 10% applicable to refurbishment works that include solar panels.
CAE discount (Energy Saving Certificates) for replacing gas boilers with heat pumps, applied directly to the quote.

New (RDL 7/2026): Expansion of shared self-consumption to a 5 km radius (previously 2 km). Ideal for energy communities in neighbourhoods, industrial estates or municipalities of the Barcelona metropolitan area.

Price of solar panel installation in Barcelona

The price of a solar panel installation depends mainly on 3 factors:

Size of the solar installation (power in kWp).
Type of solar mounting structure according to the type of rooftop where the solar panels are installed.
Operational complexity to bring the material up to the rooftop: need for street closure, crane, workers specialised in vertical works, etc. In Barcelona city, urban density can increase this complexity, especially in the Eixample, Gracia or Ciutat Vella districts.

Despite these variables, the vast majority of solar installations performed by SolarTradex have a return on investment period of less than 5 years, and with grants included it can be reduced to less than 3 years.

Frequently asked questions

Can I deduct the installation of solar panels in my income tax return?

If you are considering an energy transition in your home during 2026, it is essential to know the IRPF (income tax) deductions introduced by the Royal Decree-Law 7/2026. These incentives are designed to reward those who drastically reduce their dependence on fossil fuels.

Yes, you can deduct part of the investment in your solar installation. The amount depends on two key factors:

The type of home: flat in a residential building (deductions from 10% to 40%) or detached house (from 20% to 60%).
Whether the works achieve a 30% reduction in non-renewable primary energy consumption (certified with an Energy Efficiency Certificate, EEC), giving access to the higher brackets (40% for flats, 60% for detached houses).

The winning strategy

To access the maximum deductions, the most common route is to combine photovoltaic installation with aerothermal: replacing the gas boiler guarantees exceeding the 30% threshold and activating the higher deduction bracket. In addition, if you add a charger for an electric vehicle, you add a 15% independent deduction.

Joint ownership: double deduction

If the property has two owners, the deduction can be applied twice by splitting the cost of the works in two. That is, each owner can deduct up to the maximum allowed based on the type of home and action, doubling the total tax savings.

How to achieve the maximum Income Tax (IRPF) deduction (40% or 60%)?

Installing only solar panels usually stays within the 20% bracket. To reach the 30% consumption reduction required for the top brackets, the best routes are:

Photovoltaic + Aerothermal: Replacing your gas boiler with an aerothermal system and adding solar panels guarantees exceeding the 30% savings threshold. It also unlocks the direct discounts from the CAE certificate system.
If you already have electric heating: In these homes, installing solar panels alone is usually enough to achieve the 30% reduction and jump to the maximum deduction.
Adding an EV charger: Adding a charging point to the project always provides an extra independent 15% deduction.

What are the technical requirements for these Income Tax (IRPF) deductions?

The fundamental technical requirement to apply these income tax deductions is having the official technical justification corresponding to each type of action, in addition to the fact that the property cannot be used for any economic activity.

This justification is provided through official certificates and by meeting minimum improvement thresholds:

1. Energy Efficiency Certificates (CEE): They are essential to justify deductions linked to the efficiency and reduction of the property's or building's consumption:

For demand reduction: The CEE must certify that the work has reduced heating or cooling demand by at least 7%.
For primary consumption improvement: The CEE must show that non-renewable primary energy consumption has been reduced by 30%, or that an A or B energy rating has been reached.

2. Electrical Installation Certificates (CIE): Required for electricity generation installations:

For renewable self-consumption: The installation of photovoltaic panels is certified through the CIE. A vital requirement is that this specific deduction is not cumulative with the building rehabilitation deductions mentioned above.

3. Physical infrastructure:

For electric mobility: The requirement is to physically install charging points for electric vehicles (EV) that are owned by the taxpayer.

How is the 30% reduction calculated to qualify for the maximum Income Tax deduction?

The 30% reduction refers specifically to the decrease in non-renewable primary energy consumption of the property or building.

Although the regulations do not specify the exact mathematical formula, the calculation and official certification must be carried out through the Energy Efficiency Certificates (CEE). This technical certificate compares the previous and subsequent state of the property to justify access to the 40% deduction (individual homes) or 60% (entire buildings).

Note: The deduction also applies if the CEE proves that, after the works, an energy rating with an A or B label has been reached.

Technical analyses indicate that an integrated intervention, such as combining photovoltaic panels with the replacement of a gas boiler with an aerothermal system, virtually guarantees exceeding this 30% threshold.

Can Income Tax (IRPF) deductions and CAE incentives be combined?

Yes, they are perfectly compatible and can be combined in the same project. In fact, taking advantage of both incentives together is the most profitable strategy under the new framework of the Royal Decree-Law 7/2026.

When a deep energy renovation is carried out — for example combining the installation of solar panels with the replacement of a gas boiler with an aerothermal system — the client can access both benefits at the same time:

IRPF (income tax) deduction: this technical integration allows you to exceed the 30% threshold of non-renewable primary energy consumption reduction, which catapults you into the maximum tax deduction brackets, allowing you to deduct 40% (in flats in residential buildings) or 60% (in detached houses) in your IRPF.
Direct discount through the CAE: in parallel and in addition to your income tax return, the installation of the aerothermal system generates Energy Saving Certificates (CAE) which are now enhanced by a new multiplier coefficient. The economic value of these certificates allows the installer to apply a direct discount on the initial quotation presented to you.

Check the details on our grants and subsidies for solar panels page.

Are these deductions compatible with local Property Tax (IBI) reductions?

Yes. RDL 7/2026 legally enables municipal councils to apply reductions of up to 50% on the IBI (property tax) and rebates of up to 95% on the ICIO (construction tax) for projects that integrate renewables.

Both benefits are presented as complementary incentives alongside the state income tax deductions. There is no legal restriction preventing the simultaneous enjoyment of local and state tax advantages.

Important note on incompatibilities: The only express restriction occurs internally between the income tax deductions themselves: the 20% deduction for installing renewable self-consumption cannot be combined with the building rehabilitation deductions.

What procedures are needed to install solar panels and how much do they cost?

At SolarTradex we handle all administrative management: you only need to sign. These are the procedures and approximate costs by territory.

Procedures in Catalonia

Prior notice of works (municipal): declares the start of the installation to the town council.
ICIO (Construction Tax): 4% of the PEM (Material Execution Budget, excluding VAT and fees). Most town councils apply reductions of up to 95% — we request them together with the notice.
Municipal licence fee: approximately 1.5% of the PEM. It varies by town council; some do not charge it.
Waste management deposit: some town councils charge it (few cases) and it is usually refundable. We handle it.
Deferred notice of works: only in municipalities with specific regulations or listed areas. Currently required in: Barcelona, Badalona, L'Hospitalet de Llobregat, Sant Cugat del Vallès, Terrassa, Sabadell, Girona, Tarragona and Reus.
RITSIC (Register of Industrial Safety Technical Installations of Catalonia): €34.15 paid by the client.
RAC (Self-consumption Register): no cost. Included with the RITSIC payment.
Opening of the work centre: no cost.

Procedures in the Balearic Islands

Register of electricity production installations: free up to 15 kWn. Above this power: €46.76. Extensions, battery additions or modifications to existing installations: also €46.76.
The remaining municipal procedures (licence, ICIO, notice of works) follow the same logic as in Catalonia, with amounts defined by each town council.

Energy Performance Certificate (CEE) for income tax deduction

If you want to apply the income tax deduction, you need a double CEE certification (one prior, no more than 2 years old, and another after the works).

Do we handle it? Yes. The entire administrative process (permits, registrations, applications for reductions) is managed by our team. You receive your installation up and running and fully legalised.

How long does it take to collect NextGeneration subsidies and current grants for solar panels?

The timeframes depend on the type of grant, and with the new framework of the Royal Decree-Law 7/2026, the system has been simplified. The IRPF (income tax) deduction is applied in the following year's tax return (immediate effect when filing). The CAE system is the fastest incentive, as it is applied as an immediate discount on the quotation, before the works begin.

The FACTOR 2026 call in the Balearic Islands is resolved on a strict first-come, first-served basis; after the grant is awarded and the installation justified, the Government makes the payment. The municipal IBI discount depends on each town council and is usually applied from the fiscal year following the application.

Regarding the NextGeneration subsidies awarded in 2021-2022, there are still files pending resolution or payment due to administrative overload. If you have a pending NextGeneration file, we recommend consulting our specialised content on our blog for guidance on how to complete the justification and collect the subsidy.
