Towards established solar energy industry standards

In Finland, the solar energy industry is still relatively undeveloped: there are many providers, but the industry lacks unified laws and quality standards governing installation. Anyone can mount solar panels on a roof, wall, or in solar parks. The market therefore has a wide range of different providers.

Solar power system design and installation require special attention

Solar panels are electrical devices, and due to their delicate structure and weight, they are products that must be carefully installed. It therefore matters greatly what products are used and how they are mounted to their base.

Northern snow and wind loads easily strain the panel array and put the solar panel mounting to the test. A rooftop panel array that falls can cause significant damage.

Continuous industry development

At Wisol, we continuously work on developing solar power plant mounting products and the installation methods they require. Our goal is that in the future, the Finnish solar energy market will be guided by high standards that guarantee the durability of installed solar panels and the safety of their mounting.

Wisol Service Model

Our primary goal is satisfied end users of solar power plants. We serve solar energy companies comprehensively: from Wisol, you can get solar panel mounting products as supplies or conveniently installed on-site. Our smooth collaboration model and durable mounting products guarantee a successful outcome.

We serve comprehensively in all solar power plant projects:

1. Careful project-specific mounting design

At Wisol, we design solar power plant mountings for solar parks as well as building walls and roofs. We have developed efficient and durable mounting products and methods for Nordic conditions. Our team has strong expertise in roofing safety and ground construction, so we continuously develop mounting solutions to meet the evolving requirements of the industry.

2. Proven durable mounting products

Solar panel mounting products play a key role in installation efficiency and the durability of the solar power plant itself. Because Wisol mounts are designed to be especially easy to install, you get real work efficiency for your installation project. Wisol mounts are proven to withstand Nordic snow and wind loads, so you can be confident that solar panels stay firmly in place. We only use Wisol mounting products when installing solar power plants ourselves.

3. Reliably durable and cost-effective installation

If desired, you can get a professional installation for your solar power plant from us. Our installation methods follow the strictest criteria, and we guarantee a durable and safe mounting – without compromising workplace safety. Because we only use Wisol mounting products during installation, the work can be carried out smoothly from start to finish.

4. Guaranteed safe working practices

At Wisol, workplace safety is our top priority: We always use appropriate safety equipment on site and carry out our work without rushing. We consider safety from the factory floor onwards. For example, we ensure that large racks are packed so they can be safely transported to the site and lifted into place by installers. By preventing even minor workplace accidents in advance, our team stays healthy and our projects progress to completion as planned.

5. A contact person you can always reach

In our experience, solar power plant projects require close collaboration to succeed. As our client, you can be sure that you can always reach us: before the project, during construction, and long after the project is completed.

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.
