Oulun Seudun Sähkö

Savosolar delivered -once again- the largest solar thermal installation in Finland. This system is located way North in Tupos, Liminka – less than 200 km from the Arctic Circle.

The heating load of Tupos district heating is usually covered by wood pellets. Yet during summer time, the load is often so low, that the substantial wood pellet burner cannot be properly used and an oil burner got used, instead. The special challenge here has been to design a very efficient solar thermal system that could replace the oil consumption in summer to run the district heating network almost completely fossil-free.

Flecks Brauhaus

Brewing is a very suitable application for solar thermal systems, because of the relatively low temperatures used in several production phases.

In the brewery of Flecks in Frohnleiten, a solar thermal system with Savosolar collectors is used to support the hot water production required by the brewing process. The heat from the collectors is stored in four 3,000 litre water tanks for later use in the brewing process. The mounted collectors also act as a rain shield.

Condat-sur-Vezère

This solar thermal plant, the largest in Europe for industrial process, will deliver on average 4,000 MWh/year of heat. It will cover nearly 32% of the heated water need for the steam generation in the local paper mill. With the very high solar yield – more than 1,000 kWh/m2 – this solar thermal field is the first of its kind in the world due to Savosolar high efficiency solar collectors installed on a single-axis tracking system, manufactured and installed for Savosolar by Arcelormittal, Project Exosun. 66 tilting structures, each carrying four 16 m2 collectors, follow the sun from morning to evening and maximize the heat production.

The project was developed and financed by NewHeat and Savosolar acted as the EPC contractor. Meaning, Savosolar designed the whole system, delivered the solar collectors, and realized the installation with local French companies. This installation will be a reference for the huge growing market of heat-as-a-service for industrial clients in France and world-wide.

Solar heat already makes a global difference. 🌍

Every year, solar heating saves over 40 million tonnes of oil and prevents 140 million tonnes of CO₂ emissions.

Meriaura Energy contributes to this growing impact with large-scale projects across Europe — proving that clean heat is not just the future, it’s already here.

Solar heat for cities of the future. 🌇

District heating plays a key role in Europe’s clean energy shift — and solar thermal makes it even stronger.

When integrated into low-temperature networks, solar heat provides long-term cost stability, low emissions, and local energy independence.

It’s scalable, sustainable, and ready today. ☀
