Can I put solar panels on my balcony in Czechia?
Yes — a balcony plant up to 800 W needs no building permit and no energy licence, but it isn't paperwork-free. Three conditions: max 800 W per metering point, technical prevention of export to the grid (inverter with export limiting), and registration with your distributor (ČEZ/EG.D/PRE — a simple form) plus a connection agreement; since 1 July 2025 also an arrangement covering deviation responsibility. Unlike Germany, you may not push surplus into the grid without a contract — unauthorised feed-in is billed punitively per kWh. In an apartment building get HOA (SVJ) consent — panels on the facade or railing touch common parts.
📋 The rules
- Up to 800 W: no building permit, no energy licence
- No export: the inverter must technically prevent feeding the grid
- Distributor registration + connection agreement (deviation responsibility since 1 Jul 2025)
- Apartment buildings: HOA consent for facade/railing mounting
- Plug-in per manufacturer and distributor conditions
🔓 Exceptions
- Above 800 W or with export: the full micro-source process (inspection, feed-in contract)
- A loose panel on the garden ground: the freest regime
⚠️ Penalties & fines
Unregistered feed-in: distributor sanctions billed per unauthorised kWh. Facade mounting without HOA consent: civil dispute and forced removal.

❓ Frequently asked
Do I have to report it?
Yes — a simple registration with your distributor (ČEZ, EG.D, PRE) and a connection agreement. Skipping it breaches the conditions.
Can I sell my surplus?
Not in the 800 W regime — export must be technically blocked; selling requires the full micro-source setup.
Do I need HOA consent?
For facade or railing mounting yes — those are common building parts; a free-standing panel on the balcony is a grey zone, consent recommended.
How much does it produce?
Realistically 400–700 kWh a year depending on orientation — savings around CZK 2,000–4,000/year.
Does it plug into a normal socket?
Yes, with a certified inverter per instructions; the distributor may require professional fixed wiring.
