Plugin solar in Czechia

Can I use a plug-in solar kit in Czechia? Yes, but not simply by plugging it in. Czechia has no specific law for plug-in solar. A balcony kit counts as a "micro-source" (mikrozdroj), which is a small power plant connected to the grid. Before you switch it on, you must apply to your grid operator: ČEZ Distribuce, EG.D or PREdistribuce, depending on where you live. The kit must not send electricity into the grid. Kits up to 800 W have lighter paperwork. In July 2026 Parliament rejected a proposal for a simple notification-only regime for plug-in kits, so the current rules still apply. This page explains them step by step.

General overview for Czechia

Plugin solar kits: 800 W

There is no plug-in category in Czech law. A kit is connected as a micro-source through the "simplified connection" route. That means no grid export, a device that limits export, and an application to your grid operator. Up to 800 W, no loop-impedance test is required. Czech rules usually count power from the panels (Wp), not the inverter, so check with your grid operator. Paperwork varies by operator.

Other solar kits

Above 800 W, the same simplified route works up to 10.8 kW per connection point. An electrician must first measure the loop impedance, and operators ask for a revision report, a single-line diagram and generator documents. If you already have a grid connection, you can also connect up to 10.8 kW by notification; the operator may refuse within 30 days. No ERÚ licence is needed for home systems.

Feed-in compensation

The simplified route does not allow export (0 kW reserved export). Only brief spikes while the limiter reacts are tolerated. To be paid for surplus, you need a standard connection with export capacity, a production EAN and a purchase contract with an electricity trader. Export without a contract is "unauthorised supply", and your grid operator charges for it. Even zero-export systems need a production EAN with imbalance responsibility arranged.

The legal basis for plugin solar in Czechia

Two rules set the framework.

Energy Act (No. 458/2000 Coll.), § 28(5): customers may connect a generator of up to 50 kW with a connection contract, or up to 10.8 kW by notification to the grid operator. The operator can refuse within 30 days.
ERÚ Decree No. 16/2016 Coll. on grid connection, § 16 (amended by Decrees 248/2024 and 302/2025): defines the "simplified connection" of micro-sources and of storage up to 10.8 kW. Conditions: low voltage, a technical solution that prevents export, and loop impedance within limits, which is not tested when total micro-source power is 800 W or less.

Since 1 August 2025 (Act No. 87/2025 Coll.), systems up to 100 kW for own consumption need no generation licence from the Energy Regulatory Office (ERÚ).

A May 2026 amendment would have created a "plug-in PV micro-source": inverter up to 800 VA, panels up to 2 kWp, no battery, online notification only. Parliament rejected it on 10 July 2026. EU Recommendation 2026/1007 (30 April 2026) asks member states to simplify plug-in rules, but it is not binding. This page is guidance, not legal advice.

Certification and registration requirements in Czechia

Czechia has no national registry for plug-in kits. "Registration" means your application to the grid operator for your area:

ČEZ Distribuce: most of the country
EG.D: South Bohemia and Moravia
PREdistribuce: Prague

Typical documents are the application form, a single-line wiring diagram and inverter data sheets showing export limitation. Kits under 800 W need no impedance test and no "A1" grid-code generator document. PREdistribuce still asks for an initial revision report and a form confirmed by a licensed revision technician. Use a complete kit with CE marking and an EU declaration of conformity.

On a flat's balcony, building rules usually need no permit if nothing is fixed into load-bearing structures. Balconies are normally common parts of the building, so flat owners need the owners' association's (SVJ) consent and tenants need the owner's.

How to handle your utility in Czechia

In Czechia, the grid operator (distributor) and your electricity supplier are different companies. Both matter.

Find your grid operator from your address.
Apply before you install. ČEZ uses its online Distribution Portal. EG.D has a dedicated form for sources up to 800 W without grid export. PRE takes a form by email or post.
Sign the connection contract or amendment the operator sends you.
Allow a meter change if asked. PRE fits an interval meter before commissioning.
Ask your supplier to set up a production EAN and take on imbalance responsibility. This is required even with zero export.
Wait for the operator's confirmation before switching on.

Export without a contract is charged as unauthorised supply, based on the energy exported and peak power. Example process: PREdistribuce – simplified micro-source connection.

Are there any incentives for plugin solar in Czechia?

None currently for plug-in kits. The 2026 Nová zelená úsporám programme gives interest-free loans for PV with a battery from 3 kWp, and grants mainly to low-income households (NZÚ Light). Both target larger, professionally installed systems. Solar equipment is taxed at the standard 21% VAT.
