Batteries (BESS)

Batteries for an existing PV plant

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

Stand-alone storage for municipal buildings and housing associations

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

Sharing and aggregation

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

Questions and answers

Is a battery worthwhile for an existing PV plant?

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

Can a battery be included in electricity sharing?

Yes, from 1 August 2026, see epravo.cz, 26 June 2026. We verify the conditions for your site during the survey.

How much does a battery cost?

Price after a site survey. We do not quote without one because it depends on capacity, inverter and wiring.
