Balcony solar in Slovakia: mounting and connection first
Sources checked
Before buying a balcony kit, verify permission to install it, secure mounting and the connection requirements for the actual flat. A plug-in label or a foreign power threshold does not establish that the kit may be connected in Slovakia without further steps.
Assess the physical installation
Check the balcony structure, wind exposure, fastening system, falling-object risks and access. Confirm ownership or building-consent requirements and whether the module placement affects other parts of the building.
Compare orientation, rail or wall shading and useful daytime demand. A small module's laboratory rating cannot establish how much electricity a shaded balcony will produce.
Confirm the electrical and distribution arrangement
Identify the exact inverter, protection and circuit design with the responsible specialist and distributor. Do not treat a supplied plug as evidence that every existing socket or circuit is suitable.
Include the full connection, metering and service scope in the price. Backup and battery capability are separate features, while the actual benefit depends on generation coinciding with demand and the terms for any surplus.
