Technology Overview: Solar Organic Rankine Cycle Combined Heat and Power (Eckerd Demonstration) Operating Temperature: 150°C HTF: Propylene Glycol Working Fluid: R245fa Collectors: SopoNova 4 ORC: STG-3

Background: APS Saguaro, Arizona U.S. Worlds first commercial Solar ORC power plant came online in 2006 1 MW capacity $6/Watt Install cost No plans for further deployment of the technology due to: Small scale, diseconomies of production for manufacturers High installed cost, high levelized cost of electricity (~$0.17/kWh)
