Solar capacity rose by 300 MW (megawatt) in July and is set to reach 6 GW by the end of this year, according to Polish grid operator PSE.
The strong growth was fueled by household solar installations, which account for about 80% of total solar capacity, although the development of large-scale commercial solar farms has also gathered pace.
Installed solar capacity has already exceeded the target of 5.1 GW for 2025 set out in Poland's energy policy, which was adopted earlier this year. PSE now estimates that in 2025, Poland will have at least 10 GW and potentially as much as 15 GW of solar installed capacity.
