Savosolar and its partner Jorgensen have been selected by Grupo Mexico for the implementation of their first solar thermal plant to deliver carbon free heat to their mining process. In this very energy efficient mining process, only 62 pieces of Savo 15SGM large scale high performance flat plate collectors are sufficient deliver 1,2 GWh of energy over the year and cover 100% of the production need during most of the sunny season.
Savosolar has been selected as general contractor to build the largest solar thermal system in Finland to date, on behalf of Suur-Savon Sähkö Oy for its district heating network in Puumala, which supplies households with healthy heating. In this hybrid installation the solar thermal system is producing both, high-temperature heat to district heating supply pipe and also low-temperature heat to improve heat pump plant COP.
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.”
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.
