Solar Subsidies on Mallorca 2026: What Support Is Available

Solar subsidies on Mallorca are hard to keep track of in 2026, because responsibilities and funding pots keep changing. Anyone planning a photovoltaic system rightly asks: are there still grants, or is the big funding pot long empty? The short answer: direct grants have become rarer, but you can still save a lot of money through property tax, the building permit tax and Spanish income tax. This guide explains which support the Balearic government, the municipalities and the state currently offer, who qualifies and how to apply correctly.
At a glance
Solar subsidies on Mallorca in 2026 run across three levels: direct grants from the Balearic government, tax breaks from your municipality (IBI and ICIO), and deductions in Spanish income tax. Direct grants are often used up quickly, while the municipal discounts are reliable. Always plan your application before construction starts.
What Solar Subsidies on Mallorca Mean
Solar subsidies covers all the financial benefits with which the state, region and municipality support the installation of a photovoltaic system. That includes direct grants, discounts on property tax and on the building permit tax, and deductions in income tax. The goal is to lower the purchase cost of the system noticeably.
Important to understand: there is no single subsidy, but a web of programmes from different authorities. Some pay out money, others reduce ongoing or one-off taxes. Several building blocks can often be combined, as long as you keep to the right order and the deadlines. To help you keep track, it helps to split them up by which authority is responsible:
- State level (Spain): tax deductions in income tax (IRPF) for measures that improve energy efficiency. The whole thing is administered through the Spanish tax authority.
- Regional level (Balearics): direct grant programmes from the Balearic government for self-consumption systems (autoconsumo). These pots are advertised for a limited time and are often taken up quickly.
- Municipal level (town hall): discount on property tax (IBI) and on the building permit tax (ICIO). Each municipality decides on the amount and the conditions itself.
The most important rule of thumb: direct grants are the jackpot, but uncertain. The municipal tax discounts are smaller, but predictable and permanently available in many municipalities.
Direct Grants from the Balearic Government
The largest amounts of support came in recent years from the European Next Generation funds, which were distributed via the regions. On the Balearics that ran through the government's energy authority. These programmes were in high demand and were used up after a short time in many rounds.
Careful: apply before construction starts
With almost all direct grants, the system must not yet be installed at the time you apply. Anyone who builds first and then applies usually loses the entitlement. Always clarify the order in advance with your installer or a gestoría.
Whether a new grant pot is open in 2026 depends on the current budget of the Balearic government. That changes from year to year. So check the current status directly with the official body just before your purchase:
Govern de les Illes Balears
Official portal of the Balearic government. Here you will find current calls for energy and autoconsumo under the Energy section.
IDAE - Instituto para la Diversificación y Ahorro de la Energía
National energy agency with an overview of state subsidy programmes and the distribution of the Next Generation funds.
Municipal Tax Breaks: IBI and ICIO
This level is often underestimated, but in 2026 it is the most reliable saving block. Many Mallorcan municipalities grant a discount on two taxes for self-consumption systems:
- IBI (Impuesto sobre Bienes Inmuebles): the annual property tax. Municipalities may lower the IBI for buildings with a solar system by up to 50 percent, usually for a limited number of years.
- ICIO (Impuesto sobre Construcciones, Instalaciones y Obras): the one-off tax on construction work. Here discounts of up to 95 percent are possible in many municipalities.
The exact amount and duration are set by each municipality in its own bylaw (Ordenanza Fiscal). In Palma and several larger municipalities such discounts have existed for years. You usually apply for them directly at your town hall (Ayuntamiento) once the system is registered. How such items affect your running costs is explained in our guide to running costs and utility bills on Mallorca.
Tip: check your own municipality's bylaw
Search online for "Ordenanza Fiscal IBI" plus the name of your municipality. There it is set out in black and white whether and how high the solar discount is and how long it applies. That way you know before you buy what your municipality waives.
Tax Deduction in Spanish Income Tax
If you are a tax resident in Spain, you can deduct measures to improve the energy efficiency of your home from income tax (IRPF) under certain conditions. The deduction depends on how much the measure improves the building's energy demand or energy efficiency rating, and is tied to an official energy certificate before and after the measure.
Since the percentages, maximum amounts and validity periods of these deductions change regularly, check the current status before your tax return at the official source:
For this point, a trip to a tax adviser or a gestoría is almost always worth it. The deductions are tied to evidence and deadlines, and a mistake in your tax return costs more in the end than the advice would have saved.
A rough guide to how the building blocks might affect a typical private home system. The exact amounts depend on the municipality, the system size and your tax situation:
| Posten | Kosten | Dauer |
|---|---|---|
| Direct grant (if a pot is open) | variable, often proportional | one-off |
| IBI discount | up to 50 percent | several years |
| ICIO discount | up to 95 percent | one-off |
| IRPF deduction | tied to energy certificate | in the tax return |

Common Questions About Solar Subsidies
Are there still direct grants for solar on Mallorca in 2026?
That depends on the current pot of the Balearic government. The big Next Generation funds were taken up quickly in many rounds. Check the status before your purchase directly with the Govern de les Illes Balears, as new calls appear for a limited time and at short notice.
Can I combine several subsidies?
Usually yes. A direct grant, the municipal IBI and ICIO discount, and the IRPF deduction involve different bodies. But watch the respective conditions, because some programmes rule out double funding of the same costs.
Do I have to apply before or after the installation?
Direct grants almost always beforehand, otherwise the entitlement lapses. Municipal tax discounts and the IRPF deduction, by contrast, are applied for after the installation, once the system is registered and documented.
Conclusion
Solar subsidies on Mallorca in 2026 are no longer a single big grant, but a toolkit made up of several levels. The direct grants from the Balearic government are the most valuable but least certain element, because the pots empty quickly. You save reliably through your municipality's IBI and ICIO discount and through the deduction in income tax. What matters is the right order: first check the current subsidy status, then apply for the grant, then build, and finally claim the municipal and tax benefits. If you are unsure, bring in a gestoría for the application. That way you use the full saving potential without falling foul of a deadline.
