Batteries (BESS)

Batteries for existing PV plants

Most often we add a battery to a plant that is already running. We size the capacity to your actual consumption and adapt the connection to the existing inverter. On this website we present installations of up to 1 MWh.

Stand-alone storage for municipal buildings and housing associations

For municipal buildings and housing associations we also build storage without a PV plant. Price after a site survey: it depends on capacity, inverter and connection.

Sharing and aggregation

Since 1 August 2026 batteries can be included in electricity sharing, see epravo.cz, 26 June 2026 (in Czech). A battery can be dispatched by an aggregator according to grid needs or market prices. Electricity sharing is also the subject of a separate website, shared.energy.

Frequently asked questions

Is a battery worth it for an existing PV plant?

It depends on your consumption and tariff. We assess both during the site survey, before we propose a capacity.

Can a battery be included in electricity sharing?

Yes, since 1 August 2026, see epravo.cz, 26 June 2026 (in Czech). We check the conditions for your building during the site survey.

How much does a battery cost?

We quote after a site survey. Without one we do not give a price, because it depends on capacity, inverter and connection.
