Solar panels for homes — from quote to grid connection

What can be installed for a home?

We install rooftop systems, ground-mounted plants, battery storage, EV chargers and hybrid inverters — all from one place, compatible with each other.

Rooftop solar

The choice of most homes — panels for pitched, flat or shingle roofs, roof warranty preserved.

from €9,840 + VATRead more

Ground-mounted solar

When you have more land than roof — panels at the optimal angle, higher output.

from €10,940 + VATRead more

Battery storage

A Deye BOS-G home system keeps the daytime production for the evening and powers the house during an outage.

module €880 + VATRead more

EV charger

A VOOL or Deye home charger that uses your own solar energy first.

from €1,500 + VATRead more

Hybrid inverters

Deye single- and three-phase inverters that manage the flow between panels, battery and grid.

How much does a solar park for a home cost?

A 15 kW rooftop system costs €9,840 + VAT and a 15 kW ground-mounted system €10,940 + VAT, both without a battery and including installation. The price covers panels, inverter, mounts, electrical work and installation.

Prices exclude VAT and a battery. The price changes if the capacity differs from 15 kW, the roof is flat or shingle, the plot needs preparation, or the Elektrilevi connection capacity has to be increased. We inspect the site and prepare a transparent quote with no later extras.

Rooftop or ground-mounted — which suits my house?

Rooftop suits you if the roof surface is free and south-facing. Ground-mounted suits you if you have more land than roof or want higher output.

In both cases we design the system around your consumption and connection capacity. Read more about rooftop solutions or building a ground-mounted plant — if you are unsure which suits you, we come to inspect the site.

How does installing a home solar park work?

A 15 kW solar park is completed in one working day, on a roof or on the ground. The whole way from the first call to the grid connection is five steps.

1. We inspect the houseWe assess the roof type and orientation or the suitability of the plot, the connection capacity and the consumption profile.
2. We prepare a quoteWe calculate capacity, production forecast and price — transparently, with no later extras.
3. We sort out permitsWe deal with Elektrilevi and, where needed, the local municipality for you.
4. We install in one dayMounts, panels, inverter, fuses and cabling according to current standards.
5. We configure and hand overWe connect to the grid, set up monitoring, and issue the measurement protocol and warranty.

What exactly is asymmetry?

Estonia's electricity metering works phase by phase — also when you sell surplus solar energy to the grid.

Buying is problem-free, but when selling to the grid, if even one phase sells over the permitted limit, Elektrilevi as the grid operator imposes a penalty for it. An inverter can be symmetric (produces equally into every phase) or asymmetric (produces into the phase where consumption currently is).

Example at home: a kettle draws 3 kW from one phase. A symmetric inverter produces 2 kW into each phase — for the single-phase device 1 kW has to be bought in addition, together with the electricity price, renewable energy charge and grid fee, while the two other phases sell their surplus cheaply to the grid. This phenomenon is called netting.

Asymmetric inverters (e.g. Deye) generate into the phases according to the phase load — the missing kilowatt is taken from another phase instead of being bought from the grid. Inverters up to 15 kW have 50% asymmetry, 20 kW and above 100% — read more on the hybrid inverters page. With an asymmetric inverter, sales to the grid can also be limited to zero if needed, which matters if the Elektrilevi grid is overloaded in the area.

How fast does a home solar park pay for itself?

The typical payback period is 6–7 years without a battery and without subsidies.

Panels last over 25 years, so after payback the system produces free electricity for almost two more decades. Payback depends above all on how much of the production goes to self-consumption — on self-consumed electricity you pay no electricity price, grid fee or renewable energy charge.

Self-consumption can be raised in three ways: with battery storage, which stores the daytime production for the evening; with an EV charger, which charges the car by solar production; and by scheduling larger loads for the daytime. An asymmetric inverter also helps avoid netting loss.

A complete home solution: panels, battery and charger

We install all three systems together, with one site visit and one quote — this keeps cabling and configuration more economical than ordering them separately.

An illustrative example, not a quote. The actual price depends on the roof, the cable run length and the chosen battery capacity — we give the exact price after the site visit.

Why is it worth building a solar park for a home?

Does a home need a permit?

A rooftop solar system on a home always needs a building and use notice (ehitus- ja kasutusteatis), and the Elektrilevi connection has to be agreed as well. The exception is a house that is still being built, where the solar plant is legalised during the occupancy permit procedure. A larger ground-mounted plant mostly needs a municipal procedure too.

We clarify the need already at the site visit, prepare the building and use notice and sort out all the documents for you — read more on the rooftop and ground-mounted pages. If you are planning the system for a business rather than a home, see solutions for business.
