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

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.

Solar Thermal Bankable – yes or no?

Submitted by Baerbel Epp on January 7, 2013

It is not easy at all to persuade third parties to finance large-scale ESCO (Energy Service Company) projects for solar thermal: The financial sector needs to become more aware of solar thermal technology and its related projects. This is the lesson that Austrian company S.O.L.I.D. learned after looking for investment partners for several months. In the first half of 2012, S.O.L.I.D joined a number of projects, in which the Austrian company takes over the role of the energy provider. The clients had already confirmed these projects, which are worth altogether EUR 10 million. So, S.O.L.I.D. asked Barry Durham, founder of Critical Mass Capital in Little Rock, Arkansas, to be its capital advisor. Durham contacted 17 European and US banks, four private investment funds and two investment bankers in the United States - without any success! In the meantime, some clients have already halted their project; for some of the others S.O.L.I.D. is still negotiating with banks.

Submitted by Baerbel Epp on August 22, 2011

 United World College (UWC) in Singapore” The solar thermal cooling plant at the United World College (UWC) in Singapore has now entered the commissioning phase. The system's collector surface covers an area of 3,900 m² and powers a 1,500 kW cooling unit, which is based on a single-effect lithium bromide absorption chiller. The United World Colleges are international schools with an emphasis on social and environmental issues. With 2,900 pupils, Singapore's UWC is the largest of the 13 colleges spread around the world.
