Opening ceremony of the world’s biggest solar thermal cooling system in Arizona by the Austrian Federal Ministry of Environment, Andrä Rupprechter, the vice president of the Austrian Chamber of Commerce (WKO) Roth, and S.O.L.I.D.

Art1 ArizonaOn September 22nd 2015, governmental and expert representatives celebrated the solar thermal cooling system from SOLID with a collector area of 5,000 m². The new system supplies the Desert Mountain High School with about 2,300 pupils based on a cooling capacity of 1.7 MW.


The US federal state of Arizona, with approximately 320 days of sunshine per year is an ideal region for the use of solar thermal energy. And, the energy demand is high: approximately 70% of the produced electricity in this region is used for the operation of air conditioners.


The specific solar collectors, the control and safety technology as well as the know-how of SOLID in order to build and operate such a system come from Austria. 1,000 tons of CO2 emissions per year are prevented by the system.


In Arizona, SOLID has already installed 3 solar thermal systems in the last years for the well-known US beverage producer PepsiCo. The company uses the energy to produce process heat for its energy drinks.
