USA: S.O.L.I.D. Operates 3.4 MWth Cooling System as ESCO in Arizona

Submitted by Baerbel Epp on August 29, 2014
Desert Mountain High SchoolIt is an ideal location for solar cooling use: Scottsdale, a US city in the Greater Phoenix area in Arizona enjoys an average of 312 days of sunshine every year. Between May and September, temperatures rise above 38°C and can even reach 46°C on a hot day. This is where in July 2011, Austrian company S.O.L.I.D has started to plan a solar cooling system for Scottsdale’s Desert Mountain High School (DMHS) of 2,600 students. Three years later, the 3.4 MWth (4,865 m² of collector area) system went into operation and is now supplying heat to a single-effect lithium bromide absorption chiller with a cooling capacity of 1,750 kW. The solar cooling installation at the DMHS is currently the largest of its kind in the world, having surpassed the 2.7 MWth solar thermal capacity (3,900 m²) of another S.O.L.I.D system at the United World College (UWC) in Singapore.

Austria: Solar Process Heat Cheaper than Oil Boiler

Submitted by Baerbel Epp on May 31, 2014
Berger The solar process heat plant at Fleischwaren Berger in Sieghartskirchen, Austria, went into operation in July 2013. With its 1,067 m² of high-temperature flat plate collectors, it pre-heats water for steam and hot water production. According to calculations by Austrian company SOLID, which was responsible for the planning and the turnkey installation, the solar plant can deliver usable heat at lower costs than the existing oil boiler over a 25-year period and with a favourable interest rate.
