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.

Savosolar has been selected to deliver a tracker mounted solar thermal plant for the district heating of Nansha, Guanghzou, China. The system is combined with a geothermal seasonal storage and a chiller (not in Savosolar’s scope of supply) which allow the owner to deliver healthy energy, both heating and cooling, to its customers.

Savosolar’s first commercial solar cooling system was delivered to a school in Ukraine. The entire school was pre-fabricated in Finland and delivered to Ukraine by Elemenco Oy.
Outside of the cooling period, the solar thermal system produces energy for domestic hot water and space heating needs. During the hot summer time, three adsorption chillers cool the building via the air handling unit. The adsorption chillers, which were delivered by Savosolar, are driven by the solar thermal system.

As a general contractor, Savosolar built a solar thermal system on behalf of Fernwärme Ettenheim GmbH for the largest possible solar feed-in into the existing district heating network. 112 pieces Savo 15 SG-M large collectors generate fuel-free healthy heat, which is temporarily stored in two 100 m³ buffer storage tanks.
This also allows the operating hours of the CHP and the biomass boiler to be optimized. The scope of delivery included the fence and video surveillance system, as well as the creation of a meager meadow to enrich local biodiversity.
The construction work was temporarily interrupted due to the COVID19 restrictions. All system hydraulics were completely housed in a container. The keys were handed over in October 2020.
A PV system still to be built on the east side will generate the electricity for the pumps in the future.
