Solar Panel Installers Girona
The city of Girona has a predominantly sunny climate with hot, dry summers. This climatic condition favors the efficiency of solar panels, since they operate more effectively in sunny conditions and with moderate temperatures.
Likewise, solar radiation in Girona allows a high potential for solar energy generation. Solar panels installed in this region have the capacity to produce a significant amount of electricity, which can help reduce dependence on conventional energy sources and decrease greenhouse gas emissions.
Why install solar panels in Girona?
Solar energy allows consumers of different types to produce their own electricity, covering part of their electrical needs at a lower cost than that normally purchased from electricity suppliers and thus avoiding the emission of CO2 associated with traditional electricity generation.
Solar self-consumption is the ability of one or more consumers to generate, manage and consume energy at the same site or remotely, whether with or without energy storage. Each kWh produced and self-consumed is 1 kWh less that we must buy from the electricity company with its corresponding savings on the electricity bill.
Solar energy allows us:
- Save more than 50% on our electricity bill from day one.
- Avoid rising electricity prices.
- Take economic advantage of roofs.
- Reduce the carbon footprint associated with our daily lives.
- Contribute to a cleaner and more responsible world.
Requirements for the installation of solar panels in Girona
These are the prerequisites for the installation of solar panels in Girona:
- Drafting of a technical report (installations up to 10 kW), or a technical project (installations of more than 10 kW or public premises)
- Request for connection point to Endesa Distribución (only for projects of more than 15 kW)
- Processing of a prior notice of works at Girona City Council.
- Opening of a work center and implementation of a health and safety plan.
Once the installation is complete, you must:
- Prior inspection by an Accredited Control Body ((only for projects of more than 15 kW or public premises)
- Signing of the technical access contract with Endesa Distribución (only for projects of more than 15 kW)
- Registration in the Registry of Industrial Safety Technical Facilities (RITSIC)
- Registration in the Self-Consumption Registry of Catalonia (RAC)
- If you want to install solar panels in Barcelona, it is highly recommended to hire a comprehensive service from a specialist solar energy company, including engineering work, prior processing, supply of materials, installation, legalization and management of tax credits and/or subsidies.
Neighbour communities (Collective or shared projects)
If you want to install solar panels in your neighborhood community, you must provide:
- Owners' agreement: It is required to obtain the approval of a MAJORITY of the community's neighboring owners, which must be reflected in a legal document, such as a minutes of the owners' meeting. In the case of rental homes, it is necessary to consult with the landlords or owners of the homes.
Subsidies and tax credits available in Girona.
Currently there are different lines of incentives to help pay for a solar panel installation.
1. Aid from The incentive program linked to self-consumption and storage, with renewable energy sources and implementation of renewable thermal systems.
2. European aid for improving the energy efficiency of homes (Next Generation)
3. Grant of 50% of the Real Estate Tax (IBI) for 3 years.
4. Grant of 50% of the Economic Activities Tax (IAE) for 3 years
5. Deduction of 40% of the investment in the Income Tax Return (IRPF).
Solar panel installation price in Girona.
The price of a solar panel installation depends mainly on 3 factors:
- size of the solar installation.
- type of solar structure to use depending on the type of roof where the solar panels are installed.
- complexity of operations to raise all the material to the roof: need to cut the street, need to have a crane, need to have workers specialized in vertical work, etc.
In any case and despite these complexities, the vast majority of solar installations have a return on investment period of less than 5 years, and if subsidies are obtained, 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.
