Finland’s solar power capacity more than doubled in half a year – a big uncertainty factor in the future of the industry

Finland’s solar power capacity more than doubled during the beginning of the year, the Finnish Renewable Energy Association says in its press release.

In the first half of the year, electricity production started in eight industrial-sized solar power plants with a total output of 478 MW. At the end of 2025, Finland’s industrial size solar power capacity was 364 MW. So the growth was a whopping 131 percent.

By June, there were a total of 45 industrial-sized solar power plants in Finland, with a combined output of 842 MW.

The beginning of the year was historic for solar power in other ways as well. Both Kalanti, Finland’s largest solar power park, and Joroinen Hallanvahti, Finland’s first solar power park operating entirely with solar trackers, started their electricity production at least in test operation.

“The growth rate of solar power has been significant, and industrial-scale solar power exceeded the 500 megawatt threshold in just a couple of years”, the CEO of Suomen renewables Anni Mikkonen says in the announcement.

During the beginning of the year, industrial-scale wind and solar power reached a historic milestone, when their combined capacity exceeded 10 GW. The growth of wind power really started in 2012 and solar power construction started on a large scale in 2024, so the growth of the sectors has been fast in Finland.

According to Mikkonen, the growth rate of renewable energy in Finland has been exceptional on a European scale.

Politically, solar power is currently in a somewhat uncertain situation in Finland. The new land use law presented by Orpo’s government has caused companies developing solar power to put planned projects on holdTekniikka&Talous reported in mid-May.
