About us

Renewable energy, properly installed, for decades.

We're Joaquín and Juan, two partners working together since 1998. JSL is our Mallorcan company, specialised in renewable energy — solar PV and heat pumps. We combine real hands-on trade with proper engineering: every installation starts from a real survey and a quote itemised line by line.

We're an official RITE-licensed installation and maintenance company, authorised electricians (REBT) and certified to handle fluorinated gases of any charge. We work to the regulations in force (CTE, REBT, RITE) and we take care of the whole thing: design, installation, legalisation and the maintenance afterwards.

Quality

We work with leading brands

We work with most manufacturers on the market, but these are the ones we install most: equipment we trust and have been fitting here in Mallorca for years.

How we work

How we do things at JSL

At JSL we don't just bolt units to the wall — we build installations to last. Every project starts from a real engineering calculation and gets legalised with the authorities, with its certificate and paperwork, because getting it right today saves you a headache tomorrow.

We work with top brands (Fronius, Victron, DAITSU, Fujitsu, Schneider…), the same ones we've been fitting in Mallorca for years, and we handle everything with one team: survey, installation, legalisation and your grant paperwork. You decide; we take care of the rest.

One detail that says a lot about how we work: we use top professional tools — Testo calibrated instruments, Bosch and Milwaukee on site — and every maintenance visit ends with a digital report with photos and readings. It is not for show: it means we can show you exactly what we checked in your installation.

Clean energy

Every installation makes Mallorca greener

Switching to solar self-consumption and heat pumps doesn't just save you money: it cuts emissions and frees you from fossil fuels.

Less CO₂

Every solar kWh you use avoids the emissions that the same energy would generate if taken from the grid.

100% renewable energy

Mallorca's sun: a clean, free and inexhaustible source all year round.

Goodbye gas and oil

Heat pumps replace fossil-fuel boilers with an efficient, quiet heat pump.

A more sustainable home

You improve your home's energy efficiency and increase its long-term value.

Why choose JSL

Technical guarantees and fixed-price quotes

We eliminate surprises and guarantee excellence in every screw, cable, and pipe.

Fixed-price quote, no surprises

We calculate and study the drawings in detail. The price we sign in the quote is the final price to the cent. No unexpected increases or hidden costs.

Warranty & RITE Official License

We are an installation and maintenance contractor licensed for RITE and REBT (low voltage) by Industry, with official certifications for boilers and fluorinated gases handling of any charge. All our installations are delivered officially certified with a 5-year JSL warranty.

Direct attention with no middlemen

No call centres, no outside sales reps. You talk to us, Joaquín and Juan, the same two who actually do your installation in Mallorca — directly.

Common doubts

Frequently Asked Questions

Everything you need to know about renewable energy and climate control in Mallorca.

What solar panel subsidies are available in Mallorca?

Several subsidies are active in Mallorca for solar panel installations: FOTOPAR grants from the Govern Balear (600 €/kWp residential), income-tax (IRPF) deductions of up to 40-60% for energy efficiency improvements (RD-Law 19/2021), and municipal property tax (IBI) rebates — up to 100% for 6 years in Palma (art. 18.2), 50% in Calvià, Llucmajor and Manacor.

How do heat pumps (aerotermia) combine with solar PV panels?

Combining both technologies is highly efficient: the free electricity produced by your solar panels during the day directly powers the heat pump to heat or cool your home and generate hot water, minimising your grid consumption.

What is RITE and why is it mandatory to hire a licensed company?

RITE is the Regulation for Thermal Installations in Buildings. By law, air conditioning, heating, and heat pump installations must be executed, certified, and maintained by a contractor licensed by the Directorate General of Industry (like JSL) to guarantee safety and efficiency.

Can solar panels be installed on countryside homes off the grid in Mallorca?

Yes, we do. We install off-grid solar systems on rural estates in Mallorca, each one sized to the way you actually live. We design the system with high-efficiency panels and lithium battery storage, sized to guarantee full power autonomy and a stable supply with no grid connection.

How much does a solar PV or heat pump installation cost?

The price depends on the size of your home and your needs, which is why we always work with a fixed-price quote after a free study. As a reference, a residential self-consumption system usually pays for itself in a few years thanks to the savings on your bill and the available grants.

How long does the installation take?

A residential solar PV installation usually takes us 1-3 working days; a heat pump, depending on the home, 2 to 5 days. We handle the official certification and the grant paperwork for you, with nothing for you to worry about.

What maintenance do solar panels and heat pumps need?

Solar panels need very little maintenance: a periodic check and occasional cleaning. A heat pump needs simple servicing once a year. As a licensed company, we offer the maintenance service and the official warranty so your installation performs for decades.
