Czech solar power plants generated 20% more electricity in 2025, but growth slowed

Solar power plants in Czechia generated a total of 4.7 TWh of electricity in 2025, up 20.5% year on year. Their share of total electricity generation reached 6.6%, while total installed capacity approached 5 GW. Although solar energy remains the fastest-growing type of generation source, the pace of construction is slowing, with newly installed capacity nearly 20% lower year on year.

In recent years, solar energy has once again become one of the key pillars of the transformation of the Czech energy sector. Following a hiatus of more than a decade caused by the solar boom of 2010 and 2011, photovoltaic sources have returned among the fastest-growing sources of electricity in the Czech Republic.

However, the sector's growth is gradually slowing, and solar energy is beginning to face new challenges, particularly economic ones. Nevertheless, photovoltaics continues to strengthen its role in meeting domestic electricity consumption and remains the most dynamically developing source in the Czech energy mix.
