This solar district heating system of 941 m2 in Cadaujac is an innovative and eco-friendly project, first of this type in France, develop by our customer AbSolar. The solar production is linked to a geothermal seasonal storage which lead this new neighbourhood to received 100% of renewable heat for their need in heating and hot water.
Savosolar has been responsible of the main part of the solar plant as part of an EPC contract, including the design and then the supply and installation of the solar field, the piping and the solar station with its automation system, as a turnkey solution. The 510 MWh of annual solar production allow to avoid around 100 tons of CO2 emission for such a heating need. With this project, Savosolar maintain is leading position on the French market in the supply of turnkey solar thermal plant for district heating.
This disruptive technology develops and handle by AbSolar is a forerunner project showing the possibility to reduce significantly our carbon footprint for the daily needs of heat and should help us to fight climate changes, while ensuring a mainly fixed cost of energy over 20 years for the inhabitants of this kind of residential district.
Savosolar delivered -once again- the largest solar thermal installation in Finland. This system is located way North in Tupos, Liminka – less than 200 km from the Arctic Circle.
The heating load of Tupos district heating is usually covered by wood pellets. Yet during summer time, the load is often so low, that the substantial wood pellet burner cannot be properly used and an oil burner got used, instead. The special challenge here has been to design a very efficient solar thermal system that could replace the oil consumption in summer to run the district heating network almost completely fossil-free.
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.
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.
