Solar panels · Sóller

Solar panels in Sóller,
with the mountains measured in.

We install solar panels and self-consumption, with or without batteries, across the Sóller valley: village houses, orange-grove fincas, homes in the Port and in Fornalutx. We are an authorised low-voltage electrical installer: study, installation, legalisation and grant paperwork, with no middlemen.

Sóller: a valley ringed by mountains

Sóller sits in a valley closed in by the Serra de Tramuntana, open to the sea only at the Port. That decides how much winter sun reaches each roof, and it changes a lot from one street, or one hillside, to the next.

The old town and the orange-grove fincas

In the old town, stone houses with tiled roofs usually have one well-oriented roof pitch: the panels go flush with the tiles so they barely show from the street. On the valley fincas, often with orange trees and terraces, there is room for panels on an outbuilding or on the ground, in the spot the mountains shade least in December.

Port de Sóller: every hillside is different

Around the bay, houses sit on slopes facing different ways. PVGIS, which takes the terrain into account, gives the Port anything from about 1,280 to about 1,420 kWh per kWp a year depending on the spot, and in December from under 20 to about 83. So here we don't quote a brochure figure: we run PVGIS with your house's coordinates. On the seafront, stainless-steel fixings against the salt air.

Fornalutx and mountain homes

In Fornalutx, higher up and tucked into the range, PVGIS gives about 1,360 kWh per kWp a year, much like Sóller. Many houses are stone-built, with small roofs and narrow streets: we use the south-facing pitch and size the system to what the house really uses.

In numbers

What a solar panel produces in Sóller (in numbers)

According to PVGIS, the European Commission's official tool (query of 7 Oct 2026, 35° south, 14 % losses), in the centre of Sóller each installed kWp gives about 1,371 kWh a year, against 1,598 in Palma: roughly 14 % less. A 3 kWp home system comes to around 4,110 kWh a year.

The difference is in winter. In December each kWp gives about 67 kWh in Sóller; without the mountains it would give 83. In other words, the range takes almost a fifth of December's output. In summer you don't notice it: July gives 155 kWh per kWp, almost the same as Palma.

The saving is in what you use while the panels produce: every kWh from your roof is one you don't buy from the grid. With such a gap between summer and winter, the first thing we look at is your bill and in which months you use most.

Grants

Grants and local taxes in Sóller

IBI (property tax): Sóller's IBI bylaw (art. 4.6, BOIB no. 170 of 23-12-2025) gives a 15 % rebate on the tax for the 2026 tax year only, on a main residence with panels covering at least 30 % of consumption, applied for before 31 March. Whether it continues in 2027 depends on the bylaw the Town Council approves: we'll check it for you before you decide. Sóller's building-works tax (ICIO) bylaw has no solar rebate, and Fornalutx's bylaws provide neither.

FOTOPAR: the 2026 call closed on 30 April 2026. The 2027 call runs from 26 January to 30 April 2027 or until its €2 million run out, and you must apply before work starts. It requires a home address in the Balearic Islands. FACTOR 2026 does not cover the panels of a private individual, but it does cover batteries (45 %, open until 28 February 2027); you cannot claim both grants for the same thing.

If the system is paid for and finished in 2026, the self-consumption income-tax deduction (DA 62ª) is 10 %, up to €500. Income-tax (IRPF) deductions are claimed by you in your Spanish tax return, using the invoices and certificates we hand over.

We prepare the paperwork and, with your authorisation, file and justify the grant; you sign the application and the grant is paid into your bank account. The authorities decide whether it is awarded.

How we work

How we do it in Sóller, in 3 steps

Your roof in PVGIS

With an electricity bill, a few photos and the exact location we run PVGIS with the terrain around your plot: you'll know what you'd produce in December, not just the yearly average.

Permits and installation

We check whether the house is listed and what the Town Council requires, install on a frame designed for wind, and register the self-consumption (RD 244/2019) with the electrical installation certificate.

Grants

With your authorisation we file whichever grant is open at the time and prepare the technical documents the Town Council asks for.

Common questions

Frequently asked questions about solar panels in Sóller

Are solar panels worth it in Sóller, with so many mountains around?

Yes, but the numbers have to be done properly. According to the typical year calculated by PVGIS (European Commission, 35° south, 14 % losses), in the centre of Sóller each kWp gives about 1,371 kWh a year, 14 % less than Palma (1,598). The loss is in winter: in December the mountains take almost a fifth of the output (67 kWh per kWp instead of 83). In summer it performs almost like Palma, which is when a house with air conditioning or a pool uses most.

I have a house in Port de Sóller: will panels produce the same as in the town?

It depends a lot on the hillside. Checking PVGIS at several points around the Port, annual output ranges from about 1,280 to about 1,420 kWh per kWp, and in December from under 20 to about 83: some houses can't see the winter sun past the mountain. That's why in the Port we run the calculation with your house's exact coordinates before proposing anything.

Do I need a building permit for solar panels on my house in Sóller?

In the Balearic Islands, panels on a building's roof only need a prior notification, not a licence (Balearic Planning Act 12/2017, arts. 148.4 and 153.1.e). A licence is needed if the building is a Site of Cultural Interest (BIC) or listed, if the structure is affected, or if an environmental assessment is required. In the old centre of Sóller and in Fornalutx the municipal heritage catalogue has to be checked first: we look at it with you before quoting.

Is there a property-tax (IBI) rebate for solar panels in Sóller?

For 2026, Sóller's bylaw (art. 4.6, BOIB no. 170 of 23-12-2025) gave 15 % off the tax, for that year only, on a main residence with panels covering at least 30 % of consumption, applied for before 31 March. For 2027 we'll have to see the new bylaw; we'll check it for you. Sóller's building-works tax (ICIO) has no solar rebate, and Fornalutx's bylaws provide none.

My finca in the valley has no grid connection: can I run it on panels and batteries alone?

Yes. Under the Balearic Climate Change Act 10/2019, self-consumption systems on lawful buildings on rural land do not need a declaration of general interest (art. 48.3.d). If you also want a grant, the FACTOR 2026 rules require off-grid systems to prove the site is lawful. And the batteries are sized for December, the shortest month of sun in the valley, not for the yearly average.

Who legalises a solar installation in Sóller?

We do. We are an authorised low-voltage electrical installer: we sign the electrical installation certificate and register the self-consumption under RD 244/2019 on the Balearic Government's e-office. That gives you a legal system and the paperwork the grants and the Town Council ask for.
