Solar panels are extra. ### How much does a 1 MWh battery cost in Spain? €220,000–320,000 turnkey excl. VAT (€220–320 per kWh) as of 4 October 2026: battery cabinets or container, PCS, EMS, installation and commissioning. Transformer, fire suppression, foundation and the connection fee are priced per site. ### MW or MWh: what is the difference? MW is power (how much the system delivers at a moment), MWh is the energy stored. 1 MWh / 500 kW runs about 1.7 h at full power. The business standard is 2 hours: 1 MW / 2 MWh. Always compare both numbers. ### Is a licence or permit needed? A battery is part of the self-consumption installation, with no separate licence. Royal Decree-law 7/2026 lets you deduct 10% of 2026 spending on it from IRPF, up to €500, if the installation is finished and paid for in 2026. RDL 7/2026 gives storage flexible grid access and free depreciation up to €500,000 a year; RD 88/2026 lets behind-the-meter batteries join balancing markets through an independent aggregator (operating rules still being drafted). - [Storage price index](https://solarplan.app/storage-price-index) - [Battery storage in Ukraine](https://solarplan.app/solar/ukraine/storage)
