Flecks Brauhaus

Brewing is a very suitable application for solar thermal systems, because of the relatively low temperatures used in several production phases.

In the brewery of Flecks in Frohnleiten, a solar thermal system with Savosolar collectors is used to support the hot water production required by the brewing process. The heat from the collectors is stored in four 3,000 litre water tanks for later use in the brewing process. The mounted collectors also act as a rain shield.

Etelä-Savon Energia

Mikkeli city, the home of Savosolar received the “Inspiring Solution Award” in 2018 Celsius City Summit for the Ristiina Village project. It is a green district heating energy concept with a clever combination of solar thermal and wood chips.

Savosolar was involved in this award winning project by delivering turn-key solar district heating installation to the Ristiina district heating plant.

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.

Solar heat for cities of the future. 🌇

District heating plays a key role in Europe’s clean energy shift — and solar thermal makes it even stronger.

When integrated into low-temperature networks, solar heat provides long-term cost stability, low emissions, and local energy independence.

It’s scalable, sustainable, and ready today. ☀
