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.
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.
A new forerunner project on the large scale solar thermal market in which Savosolar has been involved: The first solar thermal field with double glasses collectors on trackers. This innovation has been done to optimize the annual solar production with a limited available area. This new solar thermal plant is a property of newHeat and will delivered heat the network of the city of Pons, which is managed by Dalkia.
Savosolar supply on this project consist in the complete solar field field as a turnkey solution, it means, the design, the supply and the installation of the solar collectors and its trackers, as well as the piping, until the solar station. It represents 112 Savo 15 DG-M collectors, which will reduce of 210 tons per year the CO2 emissions for the city’s heat needs.
With this new solar thermal plant for newHeat, Savosolar add a new leading reference in the French market of solar district heating. This approximately 3,000 m2 solar thermal field (aperture), will allow to replace 2,410 MWh of former gas heated heat by renewable heat on Narbonne’s city network, manage by a subsidary of Dalkia.
Savosolar, on the behalf of newHeat, built mainly the whole solar plant, from the solar collector’s field until the outlet of the heat exchanger to the storage thermal tank, ie: solar field, piping and solar station. More then 200 of our Savo 15 SG-M collectors, ensuring a high energy yield while reducing 510 tons of CO2 emissions per year from the district heating system of the city. The production of solar field during winter will even allow an increasing of the yield of the existing biomass boiler.
