Plugin solar in Estonia

Yes. In Estonia you can use a plug-in solar kit if its total output is below 0.8 kW (in practice 790 W) and you register it with your grid operator first. Elektrilevi, the country's largest grid operator, calls these "nano-production devices". Registration is free and done online in Elektrilevi's self-service. You connect the kit yourself following the manufacturer's instructions, with no electrician. By default the electricity is for your own use only, so nothing may flow back to the grid. If you want to send surplus to the grid, Elektrilevi replaces your meter for a fee. Larger systems need a full producer connection. If another company runs your local grid, check its rules.

Estonia has no specific law on plug-in solar. The rules come from the standard network-contract terms of Elektrilevi, the largest distribution grid operator, which the Competition Authority (Konkurentsiamet) approves. Since 1 March 2022 these terms include a "nano-production device" (nanotootmisseade): a generating device or group of devices with a total maximum output below 0.8 kW.

The current terms (low voltage up to 63 A, in force since 1 October 2024, point 4.8.2) say you register the device in self-service and, by default, may not feed electricity into the grid. Elektrilevi's separate terms of use for nano-production devices add that you connect the device according to the manufacturer's instructions, and that it must meet Estonian and EU product rules. Elektrilevi's technical conditions for small generators (Type A, in force since 1 June 2023) explicitly do not apply below 800 W.

Larger producers fall under the Electricity Market Act (elektrituruseadus) and the EU grid code (Regulation 2016/631). Smaller grid operators set their own terms. This page is guidance, not legal advice.

The kit must comply with Estonian law and EU product rules. Look for a CE-marked inverter with a declaration of conformity and automatic disconnection during power cuts (anti-islanding), because you must make sure your installation is separated from the grid during an outage. The grid-code test standard EVS-EN 50549-1 formally applies only from 800 W.

Before first use, log in to Elektrilevi's self-service:

1. Open your network contracts.
2. Choose the consumption point.
3. Fill in the device data.

Elektrilevi reviews the request within 4 business days, charges no fee, and sends an amended network contract with a confirmation. Only then may you use the device. Report any later change in output, or when you stop using it, the same way. All nano devices at one connection point together may not exceed 0.79 kW. If your connection point already has a micro-producer or producer contract, apply to change those terms instead. Details: Elektrilevi – nano-producers.

Most Estonian homes are on Elektrilevi's grid. If your network contract is with another operator, ask them whether they accept small plug-in devices and how to register.

With Elektrilevi, register in self-service and wait for the confirmation. On a three-phase connection, plug the kit into a socket on a phase that has consumption at the same time. Otherwise your bill won't fall and the power simply flows to the grid.

In apartment buildings where the housing association holds the network contract, the 0.79 kW limit applies to the whole building, and the association must agree terms for anything more. Ask your association before fixing panels to a façade or railing.

If you produce or export more than agreed, Elektrilevi charges an extra network fee of three times your package's monthly fee. To export, order the "meter replacement" service. For more power, submit a producer connection application: Elektrilevi – connecting as a producer.

None currently for plug-in kits. Panels, inverters and batteries carry the standard 24% VAT (since 1 July 2025), with no reduced rate. The per-kWh renewable support only covers plants that produced by the end of 2020. State solar grants for small homes and apartment buildings (KredEx/EIS) are closed; check eis.ee for new rounds. Registering as a nano-producer is free, but exporting needs a paid meter replacement.
