Utility-Scale Solar EPC

We deliver large-scale solar and hybrid projects through EPC and BoP deliveries for solar parks and battery energy storage systems (BESS). Our in-house team covers development, engineering, construction, grid connection, operation, maintenance and electricity sales, ensuring bankable performance in Nordic conditions.

We have delivered several of Finland’s largest solar parks, with total capacity exceeding 200 MWp.

We deliver large-scale solar park projects: we have implemented parks with capacities of several tens of megawatts and are involved in planning projects of several hundred megawatts. We have repeatedly gained experience from Finland’s largest solar park projects.

In addition, we provide asset management, lifecycle services, and O&M for solar parks of all sizes.

One of our largest projects is the 70 MWp solar park in Simo, along with a 15-year operation and maintenance contract.

The profitability of a solar park is based on cost-efficient construction, stable electricity production, and diversified revenue streams.

On the construction side, the key is to build cost-effectively while ensuring high quality and applying the latest technologies. On the production side, profitability depends on factors such as the market price of electricity, long-term PPAs, and opportunities to benefit from reserve markets and energy storage.

In today’s market environment, project success requires optimizing the entire value chain – electricity production alone is not enough.

Solarigo supports its customers in ensuring that the park delivers competitive electricity while also maximizing returns from all available market opportunities.

Solar parks are connected either to the national transmission grid or to the local distribution network. Customers can access solar power through long-term Power Purchase Agreements (PPAs), which offer stability and predictability for decades ahead.

The greatest – and often underestimated – risk is investing significant time and resources into a project whose financial foundation is ultimately too weak. One well-developed project is worth far more than ten mediocre ones.

The cost level of a solar power plant is not determined by panel and inverter prices alone; the real cost is largely driven by infrastructure construction, which can vary greatly depending on the site.

That is why experience and specialized solar expertise are critical. We mitigate risks through careful project development, technical design, and long-term contractual models. As an EPC provider, we implement projects with the same cost discipline as our own investments: every project could fit into our own portfolio.

Planned legislative changes are making permitting increasingly challenging. Building on agricultural land and forests is becoming more restricted, shifting the focus to wasteland and peatland sites, which are often more expensive and technically complex. For this reason, launching projects now is clearly more advantageous than waiting.

We provide comprehensive asset management services for solar parks, including plant operation, administrative management, production monitoring, performance optimization, preventive maintenance, and market operations. This ensures predictable returns and a profitable investment for the customer.

Yes, hybrid solutions with solar and energy storage are increasingly in the core of what we do. We deliver projects where a battery storage system (BESS) is integrated with the solar park to optimize production and enable participation in the transmission system operator’s reserve markets.

We don’t just build solar parks – we deliver profitable investment opportunities. As Finland’s most experienced solar park developer and market leader, we have implemented the country’s largest solar power project multiple times.

Instead of dealing with five subcontractors, with Solarigo you get one accountable partner who takes responsibility from start to finish: we provide the full chain from project development and EPC delivery to asset management services – all under one roof. With us, you have one partner, no excuses. That means a true sense of control, transparent costs, and accountability that doesn’t vanish.

We also manage our own parks, so we deliver more than just megawatts from a power plant.
