Poland is projected to reach 59.1 GW of cumulative solar capacity by the end of 2035, according to new analysis from London-based consultancy GlobalData. The country is expected to maintain strong annual solar additions of between 3 GW and 4 GW through the mid-2020s, driven by both large-scale projects and distributed generation.
GlobalData estimates that Poland will add around 3.7 GW of solar capacity in 2025, bringing total installed capacity to approximately 24.9 GW. Similar deployment levels are forecast for 2026 to 2028, before annual additions begin to slow slightly in the early 2030s.
Based on this trajectory, Poland is expected to surpass 30 GW in 2026, exceed 40 GW by 2030, and pass 50 GW in 2033, coming within less than 1 GW of 60 GW by the end of 2035.
Solar power is also set to strengthen its role as Poland’s dominant renewable energy source. GlobalData projects that solar will account for nearly 65% of Poland’s total renewable capacity by 2035.
According to GlobalData, Poland’s solar expansion will be supported by utility-scale project development, distributed generation growth, and auction-based incentives under the Renewable Energy Sources Act, alongside grid investments and long-term policy visibility provided by the updated National Energy and Climate Plan.
Despite this momentum, coal remains significant in Poland’s power mix. However, coal-fired capacity is expected to decline from about 32.2 GW in 2024 to around 20.5 GW by 2035, as solar and wind increasingly reshape the country’s power system.
it is currently one of the largest exporters of photovoltaic products in China.
