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.
Largest solar thermal plant in Finland
Savosolar has been selected as general contractor to build the largest solar thermal system in Finland to date, on behalf of Etelä Savon Energia Oy for its district heating network, which supplies households with healthy heating. The plant operate as an additional peak load sources during summer season while the main boilers are out of service.

Bad Rappenau, Germany (largest flat plate collector plant in Germany)
Savosolar has been selected as general contractor to build a +20 MW solar thermal system on behalf of Bauer Holzenergie GmbH for its district heating network, which supplies households and an industrial process for drying fruits with healthy heating. Only about 1,800 pieces of Savo 16S large scale high performance flat plate collectors are sufficient to getting combined with an 8,000 m³ heat storage tank and
provide carbon free heat for the needs of all connected consumers.
Additionally, a PV system will be built on site to generate the electricity consumed by the solar pumps, thus
unburdening the local power grid.
Swimming halls are very well suited for solar thermal production. Typically, their heat consumption is big and the required temperature level tends to be relatively low. In such cases solar thermal collectors are operating with a very high efficiency.
However, quite often swimming halls are closed some time of the year and summertime closure may mean extra challenges for solar heat supply.
For Hämeenlinna swimming hall Savosolar solved this issue by feeding surplus solar energy in summer to the nearby district heating network. Thus, the solar system is producing heat all days and depending on the swimming hall’s actual heat demand, the facility is either a district heating provider or a consumer.
