The solar market of Croatia continues to grow steadily, led by the self -supply and commercial and industrial (C&I) segments, while regulatory barriers block the development of utility scale on utility scale.
CroatiaThe cumulative solar capacity reached 1,099 MW at the end of June 2025, according to figures from the renewable energy sources of Croatia Association (Res Croatia).
The total figure consists of 980 MW connected to the distribution network and 119 MW to the transmission network. At the end of June, Solar accounted for 5.4% of the total electricity generation in the country.
Res Croatia told PV -Magazine That an average of 32 MW was added in each of the first six months of the year. Croatia has a total installed 397 MW of solar energy in 2024, making the cumulative capacity at around 872 MW, and the 1 GW milestone in May. If the trend continues in the first half in 2025, it is expected that the solar capacity of Croatia will reach 1,290 MW towards the end of the year.
Res Croatia said that the self -supply segment experiences the most dynamic growth, especially among households and public institutions. Households secured subsidies for a maximum of 50% of the installation costs in the first half of the year through the Environmental Protection and Energy Efficiency Fund, in addition to local incentives from provinces and municipalities. The C&I sector also expanded, supported by co-financing of the Modernization Fund.
Res Croatia, on the other hand, said that the segment on a Nuts scale is largely stagnating due to regulatory barriers, although two solar plants on utility scale with a total capacity of 17.5 MW were connected to the transmission letter during the first half of 2025.
When asked which legal changes are needed to support the Solar Market of Croatia, RES Croatia said that the connection costs of units for the transmissions – required by law since 2022 – must still be implemented. It noted that this is blocking around 50 projects, the most solar energy, with a combined capacity of 3 GW.
Limiting provisions on the development of energy storage were mentioned as a new barrier. The association calls for a regulation framework for storage systems for battery energy, together with stimulation schemes for projects on both household and utility scale, and noted that preparations for a national support schedule started in the first half of the year.
Res Croatia added that although changes in the RES and the High-Efficience Cogeneneration ACT yielded some market improvements in the first half of the year, the most important objectives of the EU Red III directive remain unqualified-especially when accelerating the implementation of renewable energy sources and a related infrastructure.
“The second half of the year is expected to make further legislative changes, which we hope will be more favorable for both citizens and large -scale producers,” the association told PV -Magazine.
