Solar power is rapidly becoming a key part of Finland’s renewable energy system. It complements wind power, balances fluctuations in generation and produces electricity especially during summer, when electricity demand is highest due to cooling needs in facilities such as data centres. The Solar 2026 event highlights that the role of solar power is no longer limited to electricity generation alone, but is increasingly connected to electricity markets, flexibility and energy system security.
Solar power has grown rapidly in Finland in recent years, and the market is still at an early stage. Estimates suggest that Finland’s solar capacity could reach up to around 15,000 megawatts by 2035, including small-scale solar installations.
“Solar PV emerges to a core element of a low-cost, sustainable and resilient energy supply in Finland, thanks to very good solar irradiation from spring to autumn and declining costs”, says Christian Breyer, Professor of Solar Economy at LUT University, who will speak at the Solar 2026 seminar about the role and value of solar power in Finland’s energy transition.
Solar power also offers Finland a unique opportunity to combine energy system development with more efficient land use. Solar projects can be located on areas with limited alternative use, such as former peat production sites and other low-value land. At the same time, solar power is effectively the fastest way to increase electricity production, particularly in Southern Finland, where electricity demand is highest.
“Solar power complements Finland’s renewable energy mix extremely well. It generates electricity at different times than wind power and often in different locations, strengthening the overall performance of the power system. At the same time, solar responds to growing electricity demand, especially during summer,” says Klaara Tapper, Advocacy Manager at Renewables Finland.
The Solar 2026 seminar also highlights the growing importance of energy system security and resilience. Digitalisation, data and cybersecurity are playing an increasingly central role as the energy system becomes more electrified and diversified.
