Since 1998, two partners installing Mallorca's energy.
No subcontractors. No surprises.
What we do
Specialists in solar power and heat pumps, with the whole installation handled by a single team.

Solar panels in Mallorca →Heating, cooling and hot water from a single high-efficiency heat pump. The renewable alternative to gas and oil. We pair it with Jaga low-temperature emitters (Low-H2O), which work with the heat pump's warm water. Project and certificate to RITE, registered with the Govern de les Illes Balears.

* Grants, deductions and rebates depend on each call and the relevant authority in force, and on the applicant and property meeting the requirements (up to date with payments, legalised property registered in the cadastre, etc.). The award is decided by the authorities: we manage and file the application, but we do not guarantee that any grant will be obtained. We tell you which are available in your case.
About us
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 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
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
Switching to solar self-consumption and heat pumps doesn't just save you money: it cuts emissions and frees you from fossil fuels.
Every solar kWh you use avoids the emissions that the same energy would generate if taken from the grid.
Mallorca's sun: a clean, free and inexhaustible source all year round.
Heat pumps replace fossil-fuel boilers with an efficient, quiet heat pump.
You improve your home's energy efficiency and increase its long-term value.
Why choose JSL
We eliminate surprises and guarantee excellence in every screw, cable, and pipe.
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.
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.
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
Everything you need to know about renewable energy and climate control 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.
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.
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.
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.
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.
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.
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.
