Croatia‘s Environmental Protection and Energy Efficiency Fund (Fond za zaštitu okoliša i energetsku učinkovitost – FZOEU) will start subsidising photovoltaic systems and storage, as well as heat pumps, in single-family homes on 2 September 2026. The government in Zagreb has allocated a total of 36 million euros to the funding pot, allowing households to receive a grant towards the cost of installing such systems.

Only natural persons may apply
Applications are open exclusively to natural persons who are the owner or co-owner of a single-family home. They must have been officially registered and actually living in the building for at least 30 days prior to submitting the application. Applicants also have to file the request with the FZOEU themselves, using their credentials for the National Identification and Authentication System (NIAS). An authorised representative may act on their behalf, but needs to present a specific, notarised power of attorney.
Eligible costs
The subsidy takes the form of co-financing for the systems. Eligible costs include those for components and installation work, provided they were incurred only after the FZOEU published its announcement in late July 2026. As an exception, the fund will also consider advance payments for the installation of solar systems and battery storage that were incurred and paid from 1 January 2026 onwards. Equipping the billing metering point through grid operator HEP ODS is likewise eligible for funding, provided it was installed and paid for after 1 January 2026.

Energy-poor households receive more
Where all conditions are met, homeowners can receive up to 50 percent of the cost of the solar system as a grant, capped at 12,000 euros per project. Energy-poor households can have up to 70 percent of their costs reimbursed through the scheme. The FZOEU additionally supports battery storage up to a sum of 11,200 euros, though here too only 50 percent of the costs are eligible, rising to 70 percent for energy-poor households. Battery storage is only funded when installed in combination with a new photovoltaic system.
Detailed information on the application process and eligibility is available on the FZOEU website. The site also provides a link to the portal where applications can be submitted from 2 September 2026 at 09:00. Anyone with questions can contact the FZOEU information centre. (su)
