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.

The solar thermal plant of Verdun will supply 8 GWh of decarbonized heat for the Lacto Serum factory nearby. With an area close to 15,000 m2, it became the largest solar thermal installation for industrial process heat in Europe, exceeding Issoudun’s plant, commissioned in 2021 by Savosolar, with a few hundreds m2.
This plant is the property of Newheat and Savosolar has been chosen to realize the solar thermal field as a turnkey project.
FORS A/S is an energy company owned by three Danish municipalities. Their district heating plant in Jyderup has about 900 customers and produces about 5000 MWh solar thermal energy per year. For the rest of its energy production, the plant uses two gas boilers with 7 MW thermal capacity and two gas engines with 6 MW electrical capacity.
In Jyderup, the collector field is a so-called hybrid field, with both single and double glazed collectors. The single glazed collectors are in the cold end of the collector rows and increase the low temperature as rapidly as possible, while the double glazed collectors are located in the warm side of the collector rows where it is more important to reduce the heat losses. The collector field also has double stanchions which allows for two collector rows to connect to one and the same pipe and thereby save costs and thermal losses.
In collaboration with Eiffage Energy Systèmes, Summa Energy is providing a solar thermal plant on trackers to supply heat to the greenhouses of Les Serres Vermeil, an organic vegetable grower located in Palau-del-Vidre, France.
Summa Energy with provide a turnkey solar thermal field of 396 Savo15S collectors, as well as all the engineering of the plant and the supervision software.
