Jelling Varmeværk is a Danish district heating plant in the historical village of Jelling, which is the former home of the Viking Chief Harald Bluetooth. Apart from the 20,125 m² collector field, Jelling Varmeværk produces its energy from a 1 MW wood chip boiler, a 1.5 MW absorption heat pump and 2 gas CHP engines with a total capacity of 8 MW heat and 6 MW electricity.
The first solar system was commissioned in summer 2016 and during its first week of operation, the collector field set a new Danish record by producing nearly 5 kWh/m² in a day.
The collector field in Jelling has double stanchions which allows for two collector rows to connect to one and the same pipe and thereby save costs and thermal losses. The annual solar thermal production is about 11,200 MWh, which covers over 25% of the town’s energy need for heating.
In 2018, Jelling Varmeværk placed a second order with Savosolar for the 4,836 m² extension of the successfully running existing collector field. The extension will be installed in first half of 2019 and it will further grow the fraction of district heating produced with solar energy.
“We chose Savosolar as our collector supplier due to their high efficiency in combination with their innovative solutions. They enable us to have an environmentally friendly, stable and low price for heating over the next 20 years. Collectors have integrated hose connections which means that they disturb the landscape as little as possible in an historic village of Jelling. The collectors can also follow the curvature of the landscape which means that we didn’t have to level out the ground of the field.”
A Finnish district heating company Elenia Lämpö Oy invested in Savosolar solar thermal system to produce CO2-free energy for their customer, which in this case is a nursing home located in Hämeenlinna. The heat is used for domestic hot water and pool heating.
The installation is the biggest operational solar thermal system in Finland.
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.
Ystad Arena is located in the southern Swedish city of Ystad, and is the home arena of Ystad IF HF which is one of the country’s top handball teams. On its roof, 36 collectors from Savosolar were mounted during spring 2017. The system is owned and maintained by the municipality owned energy company Ystad Energi AB, and feeds its district heating network with clean thermal energy. Ystad Energi AB is working towards the goal of becoming fossil fuel free by 2020 and currently produces ca. 160,000 MWh of thermal energy annually, of which 97-99% are based on bio-fuels.
As much as 89% of the thermal energy for the district heating network is produced by four wood chip burners between 3 and 10 MW capacity and the rest is produced from straw, rapeseed, gas and oil. Ystad Energi AB has ca. 1,850 customers, of which ca. 1,300 are single family homes.
