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 summer 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.

Outdoor heat pump unit installed at a residential property

— 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.

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.

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.

Everything else stays out of the way.

Lights, blinds, floor heating, air conditioning, air quality — all of it on a flush panel by the door, and on your phone when you're not home. It runs on a local server in the technical room, so it keeps working whether or not the internet does.

What makes it happen

Why it matters

01 · The panel

Nothing precious in it

Standard DIN modules on the rail — relays, dimmers, shutter drives. Off-the-shelf, replaceable by any electrician, no proprietary bus. Nothing in the panel can be end-of-lifed out from under your house.

02 · Thermostats

Room by room

A thermostat in each room sets its own target. Floor heating, radiators or AC — the system picks whichever is cheapest to run at that moment.

03 · And your phone

Same house, from anywhere

The display and your phone show the same thing. Check the house from the airport, or never open the app at all — it runs itself either way.

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.

Who you're working with

Six systems.
Six trades.
One point of responsibility.

  • Barcelona · Latvia
  • Homeowners and developers
  • Retrofit and new build

A house like this usually ends up with six suppliers and no owner. Solar from one company, the heat pump from another, the network from a third — and the day the battery will not talk to the pump, each of them points at the others. We take the opposite contract. One design, one specification, one party answerable for whether the finished house actually works.

We design the complete system and specify every component down to the switch on the wall, then run the installation with vetted local trades working to that specification. The connected layer — network, controls, automation — we commission ourselves, and we sign the house off. The specification is the product, which is why it behaves the same on a single villa as it does across a development.

Independent by design

We are not a franchise for one manufacturer. Every panel, battery, pump and switch is specified because it suits the house and the budget — and we will say plainly when something is not worth buying.

A specification, not a one-off

Every house gets the same considered set of components, sized to it. Nothing is invented on site, and nothing depends on one person remembering how the last house was wired — which is why this works across a development, not only on a single villa.

Local control first

The home runs on a local server and open protocols. Lights, heating and hot water keep working when the internet does not, and nothing is tied to a single manufacturer's app.

Answerable after handover

Commissioning is not the end of it. We monitor the system remotely and support it in service — it reports a fault to us, usually before anyone in the house has noticed.
