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.
Løgumkloster Fjernvarme is a district heating company which annually supplies 35,000 MWh of heat to over 1,500 customers. Heat is produced with a hybrid heating system consisting of a 3 MW pellet boiler, a 1.3 MW hybrid heatpump, a 3 MW absorption heat pump and a solar collector field of 15,300 m2. Additionally, the plant has two gas engines which are capable of producing 7.6 MW of heat and 6 MW of electricity and a 10 MW gas boiler which acts as back-up.
In 2015, Savosolar delivered a 9,700 m2 solar thermal field to Løgumkloster. The second order of 5,600 m2 was delivered and commissioned in the beginning of 2016. The complete field consists of 1030 Savo 15 SG collectors and covers about 20% of the annual thermal energy need of the district heating network. The largest part of the heat demand is covered by the pellet boiler, but Løgumkloster Fjernvarme has plans to change this in the future by extending the solar field and building a large seasonal water storage.
Largest solar thermal plant in Finland
Savosolar has been selected as general contractor to build the largest solar thermal system in Finland to date, on behalf of Etelä Savon Energia Oy for its district heating network, which supplies households with healthy heating. The plant operate as an additional peak load sources during summer season while the main boilers are out of service.
At Summa Energy we help our customers to achieve success in their business and environmental work, while striving for the best possible customer satisfaction. See what Mr Peter Blaser, general manager of Fernwärme Ettenheim GmbH, says about our first delivery to Germany.

Fact of the week: What is solar thermal energy?
☀️ Unlike solar PV which generates electricity, solar thermal systems produce heat and a lot of it. These systems use collectors to absorb sunlight and convert it into thermal energy, which is then used in district heating, greenhouses and industrial processes.
Solar thermal energy is one of the most efficient, low-carbon heat sources available and especially suitable for applications under 100 °C.
