According to its latest report, the V4 nations increased their cumulative solar generation over the five-year period nearly sixfold, from 5 terawatt-hours (TWh) to 29 TWh. This compares to a 2.5-fold increase across the EU, which went from 125 TWh in 2019 to 308 TWh in 2024.
National-level analysis highlights that progress has not been uniform across the region. Poland boasts the largest cumulative solar capacity, surpassing 23 GW according to Ember’s report, buoyed by more than 1.5 million solar prosumers, as of June this year.
Meanwhile, Hungary experienced the largest solar boom over the five-year study period, with solar’s share of electricity generation in the country jumping from 4% in 2019 to nearly 25% in 2024. As of July 2025, cumulative capacity had exceeded 8 GW.
The Czech Republic almost doubled its solar output over the five-year period studied, Ember adds, while Slovakia lags in terms of cumulative solar capacity due to unfavorable policies and high grid connection costs.
The analysis found that in June this year, the Czech Republic, Hungary and Poland all recorded their highest-ever share of solar in their power mix. Hungary reached a high of 42%, Poland recorded 22%, and the Czech Republic hit 14.7%.
