How the System Works
Using an inexpensive flat panel type solar heat collection system, the heating fluid will be heated to approximately 200ºF and will heat the Rankine cycle working fluid.
The liquid working fluid is pumped to a higher pressure liquid, and then is heated to boiling (via the collected solar heat). The resulting higher pressure vapor is run through the expander, which is connected to a standard 3 phase induction generator, which can generate 40kW of AC electricity during peak periods.
The lower pressure exhaust of the expander is recycled via a condensing cycle back to liquid and returned to the pump.
The working fluids involved are "green".
To get solar power 24 hours a day and maintain high system availability, a thermal storage tank can be utilized. This tank can store extra hot fluid during the day for use during evening hours.
