According to the preliminary data of the Energy Authority, at the end of 2023, Finland had approximately 1,000 MW of installed solar power production capacity, 936 MW of which was micro-generation and 50 MW from industrial-scale power plants. Unconnected capacity totalled. . Solar power in Finland – summary: Solar power supports the green transition as a low-emission form of electricity production. Solar electricity can be produced close to consumption, which can reduce transmission losses and support regional self-sufficiency. In the summer, the long days and nearly round-the-clock sunlight compensate for the dark winters. Above the Arctic Circle, the sun does not rise some days in winter, and does not set some days in the summer. The total capacity increased by more than 300 MW over the year.
