4. 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

5. 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)
