Solar panels
What your solar panel installation in Mallorca includes
Solar panels in Mallorca cost between €6,500 and €8,000 in 2026 for a house with 5 kWp and no battery, and between €9,000 and €11,500 with a 10 kWh battery, turnkey and including legalisation, according to prices published by installers on the island. For private individuals there is no regional grant for the panels until FOTOPAR 2027, the Balearic solar grant scheme for households, but there are IRPF (Spanish income tax) deductions until 31/12/2026 if you pay tax in Spain as a resident.
Our team of electricians and installers in Palma takes care of everything, from the study based on your bill until the surplus compensation shows up on your electricity bill. We design the system for your real consumption, not to fill the roof.
- Study of a year's bills and a calculation of your annual saving
- Output matched to your consumption, not to the roof area
- Comunicación previa (prior notice) to the council where needed
- Panels, inverter and, if you want, a battery with backup
- Boletín (CIE, the electrical certificate), self-consumption registration and surplus set-up
- Legalisation date in writing in your contract
- App showing what your panels produce and what you use
- Optional: energy certificate before and after
Prices 2026
Solar panel prices in Mallorca in 2026
According to prices published in 2026 by installers in Mallorca, a 5 kWp system for a house costs between €6,500 and €8,000 turnkey. The unit kWp measures the output of the panels: 5 kWp is about 10 panels. You get your fixed price, with the make and model of every component, after the visit.
| System | Guide price |
|---|---|
| 3 kWp without battery, about 6 panels | 5,0006,500€ |
| 5 kWp without battery, about 10 panels | 6,5008,000€ |
| 5 kWp with a 10 kWh battery | 9,00011,500€ |
What affects the price most
- The output you need for your consumption, with air conditioning or a pool
- Whether you add a battery, and its capacity
- The type of roof: flat, tiled or on a pergola
- The distance between the panels and the fuse box
- Whether the fuse box needs renewing or the contracted power needs changing

Visit and fixed price
We look at the roof and the fuse box. You get the fixed price with the make and model of every component, and the dates for installation and legalisation.
Installation in 1 or 2 days
Our team fits the panels, the inverter and, if you want one, the battery. On a house with 5 kWp the work usually takes 1 or 2 days.
Legalisation and surplus
Within two weeks we file the boletín (CIE) and the self-consumption registration, and let you know when the compensation appears on your bill.
Guarantee and aftercare
You see your output in the app. You have a 5-year guarantee on the installation, on top of the manufacturer's warranty, and our team in Palma for servicing and faults.
What we guarantee
What we guarantee with your solar panels
The most common complaints in Mallorca are systems that are never legalised, companies that disappear and promised grants that never arrive. This is how we work so it doesn't happen to you.
Legalisation with a date
We file the boletín and the self-consumption registration within two weeks of installation, with the date in your contract, and let you know when the compensation shows up on your bill.
Sized to your consumption
We work from your bills. Surplus power earns only a few cents, so a system bigger than your consumption takes longer to pay for itself.
Backup for power cuts, if you want it
Without a battery and backup, the panels shut down when the grid goes down. With a hybrid inverter, a battery and a backup circuit, the essentials keep running.
Grants without empty promises
We tell you which grants and tax deductions you are entitled to today, with the date and source. We never promise you a grant that depends on the Govern (the Balearic government).
A team that stays with you
After installation, you call us: inspections, cleaning and faults are handled by our team in Palma. You have a 5-year guarantee on the installation, on top of the manufacturer's warranty on the equipment.
You pay as the work progresses
Nothing before you sign. When work starts you pay 10% at most, and the rest stage by stage, once each stage is finished and checked with us.
Good to know
Grants and tax deductions for solar panels in Mallorca (October 2026)
There is currently no regional grant for the panels on a private home. If you pay tax in Spain as a resident, until 31/12/2026 you have two IRPF deductions, which cannot be combined for the same installation, and if you live in the Balearics, a grant for the battery.
Self-consumption deduction: 10%
You deduct 10% of what you pay for the installation in 2026 (20% if it is installed in your residential building), with a maximum base of €5,000 a year: up to €500 at 10% and up to €1,000 at 20%. It applies to any property you own, including a second home, unless the system is used for a business activity. It must be finished in 2026, with a boletín (CIE), and paid by card or bank transfer, never in cash.
Efficiency deduction: up to 40%
If the energy certificate issued afterwards shows 30% less non-renewable primary energy or an A or B rating, you deduct 40% on your main residence or on a property you let out as a home, with a maximum base of €7,500: up to €3,000. For a second home, only the 10% deduction applies. You need a certificate before and after, the second one before 1/1/2027. Whether the panels are enough depends on each house: we work it out beforehand.
Battery: 45% from the Factor de Insularidad
If you are resident in the Balearics, the Balearic government covers 45% of the eligible battery cost through this grant scheme, even though panels are not subsidised for any individual, self-employed or not. Applications until 28/02/2027, first come, first served. You pay first and receive the money after submitting proof of the work, and the subsidised amount does not count towards the deduction.
FOTOPAR 2027: January to April
The next grant for solar panels for private individuals resident in the Balearics: €600 per kWp up to 5 kWp and €420 per kWh of battery. Applications from 26/01 to 30/04/2027, and only what you install after applying counts. In 2026 there were more applications than money.
