Wisol ja NYAB have together since the beginning of 2024 launched a large solar power plant construction project in Utajärvi, Northern Ostrobothnia.
The exceptionally large solar park contains yli 170 000 bifacial solar panels and covers an area of n. 150 hehtaaria, equivalent to over 200 football fields.
Wisol’s part of the project was fully handed over in late summer 2025. The entire project is scheduled for completion in summer 2026.
Tämän kokoluokan aurinkopuiston rakentaminen näissä olosuhteissa on tähän mennessä ainutlaatuinen näyttö Suomessa. Yhteistyö ja luottamus toimijoiden välillä on ollut avaimena onnistumiseen. Projekti sujui isossa kuvassa erittäin hyvin ja on tuonut valtavasti oppia ja uskoa tulevien hankkeiden rakentamiseen Wisolille ja muille hankkeen sidosryhmille.
Utajärvi’s previously decommissioned and overgrown peat area is coming back to life through the solar energy project. The area, which is not well suited for forestry or agriculture, is finally being put to productive use. The project will provide the Utajärvi region with a sustainable and revitalizing solution.
A total of 174,520 solar panels have been installed in the park area. The project was commissioned and developed by Skarta Energy.

Wisol served as a subcontractor in the Utajärvi project and has been involved since the geotechnical surveys. The project was carried out through Wisolin, NYABin ja designtoimisto Siteman collaboration. The seamless commitment of the three parties has enabled the most cost-effective implementation solutions, constructively leveraging each company’s areas of expertise and strengths.
Supporting the economic development of the Utajärvi region and creating opportunities for locals have been important goals in the project. These goals have made it possible for the project to also employ local workers and subcontractors from Utajärvi and its neighboring municipalities.
NYAB haluaa olla edelläkävijänä rakentamassa teollisen mittakaavan laajoja aurinkovoimaloita yhdessä ammattitaitoisten ja osaavien kumppanien kanssa.
Suomen suurin aurinkopuisto edustaa merkittävää virstanpylvästä Wisolin aurinkopuistoliiketoiminnassa, ja määrätietoisella suunnittelulla näinkin laaja ja moniosainen urakka voidaan toteuttaa hallitusti ja menestyksekkäästi.
By leveraging Wisol’s robust site-specific design and wind simulations, the durability, suitability, and reliability of the area’s foundations and racks have been ensured.
Unique, fully customized solar panel mounting racks have been created for the Utajärvi site, combining durability and cost-effectiveness. These solutions not only optimize material use in a large solar power project, where even small factors have a significant impact, but also ensure reliable durability in the area’s soil conditions under all possible circumstances.
Wisol has been motivated and committed to providing a sustainable and reliable solar energy solution that meets the challenges of local needs and environmental requirements.
