Solar panels in Tarragona and Lleida: turnkey installation
We work mainly with single-family homes, residential developments and country houses, as well as second residences on the Costa Daurada, homeowner communities and leading industrial, agro-industrial and hotel projects in the area.
Each project is designed and installed turnkey with our own engineering and personnel: energy study, paperwork, legalisation and grant management.
4 reasons to install solar panels in Tarragona and Lleida
The provinces of Tarragona and Lleida offer exceptional conditions for solar self-consumption. Here are the four key reasons:
1. Maximum solar exposure in the Mediterranean area
The Costa Daurada and the province of Tarragona exceed 2,600 hours of sunlight per year, while Lleida reaches similar figures with clearer winters. Annual solar radiation between 1,550 and 1,700 kWh/m² enables high and stable photovoltaic production, comparable to that of southern Spain.
2. Rising electricity costs and high bills
Catalonia has one of the highest electricity bills in Spain. Installing solar panels allows you to produce your own energy and reduce dependence on electricity market price hikes, especially in summer when air-conditioning consumption peaks on the Costa Daurada.
3. Fast payback and demand coincidence
The high solar radiation of the area shortens the payback period of a photovoltaic installation: between 5 and 7 years in most residential projects, and even less if combined with an air-source heat pump or electric vehicle. Peak solar production (summer) coincides with the tourism and hotel consumption peak on the Costa Daurada, as well as with the agro-industrial activity of Lleida (irrigation, refrigeration, cooperatives).
4. Catalonia, a favourable framework for solar self-consumption
The RDL 7/2026 has created one of the most comprehensive grants frameworks in Europe for solar self-consumption in Catalonia:
- Personal Income Tax (IRPF) deduction up to 60% in single-family homes when combining photovoltaics + aerothermia.
- Municipal reductions on IBI (up to 50%) and ICIO (up to 95%) in most councils of Tarragona and Lleida.
- Shared self-consumption expanded to a 5 km radius (previously 2 km): new opportunities for energy communities in industrial parks, neighbourhoods and towns.
- 100% amortisation in the first fiscal year for companies investing in renewables.
All these grants are compatible with each other, which allows a drastic reduction of the real installation cost.

Solar panels prepared for the climate extremes of Tarragona and Lleida
The province of Tarragona combines coastal areas of the Costa Daurada with dry, exposed inland zones (Priorat, Terra Alta), while Lleida faces extreme summer heat, spring hailstorms and frost in the Pyrenees. At SolarTradex we work with SunPower Performance panels, designed to withstand this climatic diversity while maintaining maximum performance throughout their lifespan.
Resistance to extreme weather events
The panels pass the IEC 61215 mechanical resistance tests, which guarantee structural integrity against hail, wind and snow load. In areas of Lleida with frequent convective storms (Segrià, Urgell, Pla d'Urgell) or in the north with snowfalls (Pyrenees), this resistance is critical. In addition, they maintain a low thermal coefficient that preserves performance even at temperatures above 40 °C, common in summer in southern Lleida.
Prepared for demanding environments
The panels have Fire Class A certification (IEC 61730-2 / UL 790), the highest fire resistance, a key factor in rural areas of Priorat, Terra Alta or Pallars with a risk of forest fires. They also pass the Ammonia Test IEC 62716 (resistance to ammonia in livestock and agricultural facilities in Lleida) and Dust and Sand IEC 60068-2-68 (resistance to dust and sand, common in agro-industrial areas). For installations on the Costa Daurada seafront, the IEC 61701 Severity 8 certification also guarantees resistance to salt mist.
Real warranty and sustainability
They offer a triple power, product and service warranty of 20 years with a minimum performance of 80% at the end of the period. The special encapsulant resists humidity, corrosion and thermal variations, extending the real lifespan of the equipment in varied climates. They also hold the Cradle to Cradle Bronze certificate, which accredits the panel's sustainability in material health, water stewardship, carbon management and social responsibility.
The most recommended option for installations across the entire provinces of Tarragona and Lleida: from single-family homes on the Costa Daurada to agricultural facilities in Segrià, rural houses in Priorat or industrial projects in Camp de Tarragona.

How to drastically reduce the cost of your installation in Tarragona and Lleida
Personal Income Tax deductions up to 60% (RDL 7/2026)
The Royal Decree-Law 7/2026 extends tax deductions for homes. There are three different deductions that can apply according to the action:
1. Deduction for renewable self-consumption
Valid until 31/12/2026.
- Flat with solar panels: 10% deduction on a maximum base of €5,000 (up to €500 savings).
- Single-family home with solar panels: 20% deduction on a maximum base of €5,000 (up to €1,000 savings).
2. Deduction for energy efficiency (rehabilitation)
Valid until 31/12/2027. Applies if the work reduces at least 30% of non-renewable primary energy consumption (or reaches energy rating A or B). Requires an Energy Efficiency Certificate (CEE) after the works.
- Flat: 40% deduction on a maximum annual base of €7,500 (up to €3,000 savings).
- Single-family home: 60% deduction on a maximum accumulated base of €15,000 (up to €9,000 savings, spread over up to 4 years).
3. Deduction for electric vehicle charger
Independent deduction. Valid until 31/12/2026.
- 15% on a maximum base of €4,000 (up to €600 savings). Added to any of the previous ones.
Tip for reaching the maximum deduction: Installing only solar panels puts you in the low bracket (10% flat, 20% single-family). To access 40% or 60% for energy rehabilitation you must reduce at least 30% of non-renewable primary energy consumption. The most common way is to combine Photovoltaic + Aerothermia (replacing the gas boiler with a heat pump). If you also add an electric vehicle charger, you get an extra independent 15% deduction.
Shared self-consumption expanded to 5 km (RDL 7/2026)
The new radius of 5 km (previously 2 km) opens new opportunities for energy communities in industrial parks, neighbourhoods or entire towns in Tarragona and Lleida. Ideal for homeowner communities, small towns and groups of nearby companies.
CAE discount for aerothermia
Energy Savings Certificates (CAE) are applied as a direct discount on the quote, without paperwork for the client. They apply exclusively to the replacement of gas boilers with aerothermia. Combining photovoltaics + aerothermia allows simultaneous access to the high IRPF bracket (40% flat, 60% single-family) and the CAE discount for the aerothermia.
100% amortisation for companies (RDL 7/2026)
Companies investing in renewable energies before 31/12/2026 can amortise 100% of the investment in the same fiscal year, instead of the usual 15 years. Ideal for industrial buildings, agricultural cooperatives in Segrià, Costa Daurada hotels or any company with positive tax profits.

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.
