Your own energy from your roof.

We design, install, and connect a photovoltaic system tailored to your roof and consumption. Panels, hybrid inverter, battery, and water heating — all under one contract, with one point of contact from site survey to final inspection.

From sunlight to socket
— five steps.

No magic. Sunlight travels through your home and turns into electricity you can use now, store for the evening, or send to the grid. We handle every step.

01

Panels

Monocrystalline panels on your roof convert sunlight into direct current. We choose the orientation and tilt based on your consumption.

02

Inverter

The hybrid inverter converts DC to grid-compatible AC and decides where the energy goes — to the house, the battery, or the grid.

03

Battery

A lithium-ion storage unit saves midday surplus for the evening and night. This boosts self-consumption from ~30% to ~75%.

04

Water heating & wallbox

Surplus energy is sent to your water heater and car charger before it would flow into the grid for free.

05

Monitoring

See production, consumption, and battery status in real time on the app. We monitor the system remotely.

A day you make yourself.

This is what a typical 6 kWp home solar system produces on a sunny day. A morning ramp-up, a midday peak, and a gradual decline toward evening — which is exactly why a battery makes sense.

What we build for you.

From a small rooftop system to a hybrid setup with battery, water heating, and EV charging. Always turnkey — design, installation, inspection, and subsidy processing included.

01

Turnkey PV system

Design, installation, grid connection, and inspection. We handle all the paperwork — from the connection request to the first kilowatt-hour.

02

Battery & storage

Retrofitting existing or new systems with a lithium battery. Use your midday surplus in the evening instead of buying from the grid.

03

Water heating

Smart diversion of surplus energy to your water heater. Cheap solar heat instead of expensive grid electricity.

04

EV wallbox

Charge your electric car primarily from your own production. Smart charging based on real-time surplus.

05

Monitoring & service

Track production in the app, remote diagnostics, and on-site service within 48 hours if something goes wrong.

06

Subsidies & financing

We guide you through the NZÚ 2026 program — interest-free loan, eligibility, application. We handle the admin.

Before you ask

Frequently asked questions.

Do I need a battery with the panels?

You don't have to, but it's worth it. Without a battery, you'll use about 30% of your own production; the rest goes to the grid at a low feed-in tariff. With a battery, you jump to ~75% self-consumption, and the payback period shortens.

What happens during a grid outage?

A standard system shuts down for safety. A hybrid system with backup capability can keep selected circuits running even when the grid is down.

How much will I actually save?

For a model household, around 41,$0 per year with a battery. We'll calculate the exact figure based on your consumption, roof, and shading — free of charge and upfront.

How long does installation take?

Typically 4–8 weeks from contract signing. The actual roof installation takes one to two days; the rest is paperwork and grid connection.

Can you handle the subsidy?

Yes. We guide you through the NZÚ 2026 program (interest-free loan), prepare the application, and provide the required documents.

What happens after 10 years?

Panels usually have a 25–30 year performance warranty, the inverter 10+ years. The system keeps producing — panel output just decreases very gradually over time.
