3kWe Solar Thermal Demonstration at Eckerd College
Matt Orosz - www.stginternational.org
Project Goals:
1. Demonstrate the viability and technical performance of micro CHP using solar thermal collectors and ORC (Organic Rankine Cycle) technology
2. Training and R&D platform for STG International mission
3. Provide Eckerd with a teaching tool and sustainable energy platform for student learning
4. Produce emissions free power

Technology Overview: Solar Organic Rankine Cycle
Combined Heat and Power (Eckerd Demonstration)
Operating Temperature: 150°CHTF: Propylene GlycolWorking Fluid: R245fa
Collectors: SopoNova 4ORC: 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)
