Our Clients

Wisol and NYAB have jointly launched a large-scale solar power plant construction project in Utajärvi, Northern Ostrobothnia. The exceptionally large solar park covers approximately 150 hectares, equivalent to about 200 football fields.
We installed solar panels for a 100-kilowatt solar energy system on the roof of an industrial hall in Eura. The main contractor for the project was PlayGreen Finland Oy.
We delivered properly dimensioned mechanics installed at the Kemiönsaari 2-megawatt solar power plant. The varying terrain posed particular challenges for the mechanical installation, but Wisol's screw pile technology achieved an extremely solid result.

Solar Park Projects

In solar park projects, a strong understanding of soil conditions and mounting solutions creates a solid foundation for optimizing design and implementation.

When needed, we fully customize our solutions to match the site conditions.

Rooftop Solar Projects

The building’s roof structure, local wind and snow loads, and regulatory requirements form the framework for rooftop solar implementation.

Durable, safe, and cost-effective solutions for different roof types are designed and implemented with solid roofing safety and construction expertise.
