What we install

Everything your home needs — nothing it doesn't.

☀️

Solar Generation

Rooftop photovoltaic panels sized to your consumption profile. Seamlessly integrated with your home's aesthetics and electrical system.

🔋

Battery Storage

Battery towers that store surplus solar energy, tucked in your basement or technical room. Charge during the day, power your home through the night — entirely off-peak.

♨️

Heat Pump & Solar Thermal

High-efficiency heat pump integrated with a multifunctional storage tank and solar thermal collectors. Heating, cooling, and hot water — all solar-driven.

🛰️

Starlink Connectivity

Satellite internet installed on the roof. Fast, reliable, independent of local infrastructure — essential for remote villas and future-proof connectivity.

📡

UniFi Home Network

Enterprise-grade Wi-Fi throughout the entire property, paired with HD security cameras. Whole-home coverage, zero dead zones.

🏠

Home Automation

A local server orchestrates every device. A wall-mounted touch display gives you full control — lighting, climate, energy charts, pool, and more. Your phone works too.

A closer look

Three systems that change everything —
three that quietly hold it together.

Of the six, the energy trio — solar, battery, heat pump — does the heavy lifting that takes your home from rating G to A. The connected layer — Starlink, UniFi, automation — is what makes living with it effortless.

— 01 Solar Generation

Sun-driven,
all year round.

Photovoltaic panels sized to your home's actual consumption profile, not a generic kit. Mounted on south- and east-facing roof surfaces, integrated into the building's electrical system, and quietly producing from first light to last.

What it replaces: most of your daytime grid draw — and on long Mediterranean afternoons, all of it.

Battery storage towers in a residential technical room

— 02 Battery Storage

The sun,
after dark.

A battery bank in your technical room captures every kilowatt the panels make beyond what your home is using. By evening it's full. Through the night it's what powers you — entirely off-peak, entirely yours.

The cabling, the mounting, the labelling — all done with the same care as the work you can see. We'll show you the room when it's finished. Most people are surprised by how quiet and tidy it is.

— 03 Heat Pump & Solar Thermal

Heat from air.
Hot water from sun.

A high-efficiency air-source heat pump handles every degree your home needs — heating in winter, cooling in summer, hot water year-round. The outdoor unit is quiet enough to live next to and runs on a natural refrigerant, so its climate footprint is essentially zero. On the roof, solar thermal collectors gather heat directly from the sun and feed a multifunctional storage tank in the technical room — the heat pump only tops it up when the sun hasn't done it already.

What it replaces: the gas boiler, the electric water heater, and most likely your standalone air conditioning too. One system, three jobs, a fraction of the energy.

Energy transformation

From the bottom of the scale
to the top.

Most Spanish homes enter our programme rated F or G. Every single one leaves rated A. The difference translates directly to your bill — and to your home's resale value.

The connected layer

It runs on a server
in the technical room.
You'll forget it's there.

01 — Controls · Jung

The one part of the system
you touch every day.

Momentary push-buttons are what clean home-run wiring needs — and they happen to be the most beautiful thing on the wall. Same range, matching USB-C and USB-A sockets.

How it's wired · home-run

Switch and lamp never touch. Each runs its own cable home to the panel, where a smart relay ties them together. The wiring stays fixed — what a button does is decided in software, and can change any time.

02 — Network · UniFi

Coverage everywhere,
and it looks the part.

The kit most people hide in a cupboard is quiet enough to leave in view. Fast Wi-Fi in every room, cameras that keep watch, all in one app on your phone.

03 — Uplink · Starlink

And above it all, Starlink on the roof — fast satellite internet that doesn't depend on the village line. The connection that stays up.

The process

Simple. Transparent.
Done once, done right.

01

Energy Audit & Design

We visit, analyse your home's current consumption, orientation, and infrastructure, then design the optimal integrated system — solar, thermal, battery, network, and automation.

02

Installation

A single coordinated installation. Rooftop panels, basement batteries, technical room heat pump and thermal system, Starlink, UniFi network, and your home automation server — all commissioned together.

03

Handover & Control

Your wall display is configured, your phone app is set up, and we walk you through everything. Pool automation, battery scheduling, climate control — you are in charge from day one.

04

Ongoing Support

Remote monitoring and local support. The system tells us when something needs attention — usually before you even notice.
