District heating

Pons

A new forerunner project on the large scale solar thermal market in which Savosolar has been involved: The first solar thermal field with double glasses collectors on trackers. This innovation has been done to optimize the annual solar production with a limited available area. This new solar thermal plant is a property of newHeat and will delivered heat the network of the city of Pons, which is managed by Dalkia.

Savosolar supply on this project consist in the complete solar field field as a turnkey solution, it means, the design, the supply and the installation of the solar collectors and its trackers, as well as the piping, until the solar station. It represents 112 Savo 15 DG-M collectors, which will reduce of 210 tons per year the CO2 emissions for the city’s heat needs.

La Caridad

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.

Fernwärme Ettenheim

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.

Narbonne

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.
