For the first time, investors and utilities in the Nordic region added more new solar capacity than wind in 2025, according to BloombergNEF. This shift represents a fundamental change in Europe's renewable energy landscape, where solar was traditionally concentrated in sunny southern regions while wind dominated the north. The trend is expected to continue in 2026, driven by plunging equipment costs and higher electricity prices that have made solar projects viable in previously unsuitable locations. As Warren Campbell, CEO of Swedish solar developer Alight AB, noted, "The question isn't whether solar works this far north anymore. It's how much we're going to build."
Governments across the region have significantly upgraded their solar installation forecasts as actual installations have exceeded expectations. Sweden reached its original 2030 solar target in 2023 and is already close to meeting a newer, more ambitious goal. Finland hit its end-of-decade target six years early, demonstrating the rapid pace of solar adoption in northern climates. The success has prompted developers to plan the next wave of projects, with companies proposing at least 300 megawatts of solar in Finland's northern Lapland region and projects of around 600 megawatts seeking grid connections in northern Sweden.
The solar boom in the Nordics has been driven by a 30% decline in panel and related equipment costs in Europe since 2021, according to Aurora Energy Research. Nordic wholesale rates have experienced dramatic volatility, averaging about €11 per megawatt-hour in 2020 before surging to more than ten times that level during the energy crisis that followed Russia's invasion of Ukraine in 2022. They averaged €79 during the first six months of this year. The European Commission's solar calculator shows that a project in northern Finland would generate around 82% of its annual output between April and September, compared to 58% for a similar project in Madrid. This economic transformation has made solar projects viable even in previously unsuitable locations.
The transformation is exemplified by Exilion's €40 million Simo solar park, located just south of the Arctic Circle. According to company director Tommi Riski, the project generates electricity for almost 22 hours a day at summer peak, with most revenue earned during summer months. In the early days of the project, the typical response was "Who the hell builds a solar plant in Lapland?" Less than three years later, the business case assumes virtually no generation between November and January, treating winter output as a bonus. The site also hosts a wind farm that generates most electricity during dark winter months, demonstrating how solar and wind technologies increasingly complement each other in northern climates. Operating far north offers additional advantages, with cooler temperatures helping solar panels operate more efficiently and snow reflecting additional light onto double-sided panels, boosting production.
The solar shift extends beyond the Nordics, with northern Scotland experiencing record solar panel installations. Nearly 2,000 homes across the Scottish Highlands and islands installed solar panels in the six months through April, despite the region receiving barely half the sunshine of southern Spain. Installation company AES Renewables has added solar systems as far north as Thurso, almost on the same latitude as Oslo. The demand has prompted AES to increase its workforce by more than 50% since the start of last year. The Faroe Islands, regarded as one of the world's cloudiest places, are also experiencing growth with local utility SEV estimating more than 60 installations, with another 25 to 30 awaiting approval. This diversification allows solar to fill seasonal gaps in the system, particularly during summer months when wind and hydropower generate less electricity.
