Summary
Poland installed 3.6 GW of solar in 2025, according to data collected by Agencja Rynku Energii (ARE) on behalf of the country’s Ministry of Energy. The figure is down on the 4 GW of solar added in 2024 and takes cumulative solar capacity to 24.8 GW.
While hybrid solar-plus-storage and solar-plus-wind systems are being considered as a key way to mitigate curtailment in Poland, Wisniewski noted a new trend in the absorption of excess renewable generation in the summer by district heating companies through power-to-heat (P2H) technologies and seasonal thermal storage.
Several Polish district heating companies are currently developing P2H investments, Wisniewski added, supported with long-term thermal storage for purchasing PV generation on a power purchase agreement basis.
