Analysis of a Power Cycle Utilizing Low-Grade Solar Energy

This paper has proposed a power system that can provide efficiently using the heat collected by the collector. The system consists a of the Rankine cycle to recover the collected solar energy. It produces power and provides certain amount of domestic hot water. Based on the models, a calculation was done to analysis the performance of the system at the typical condition. And the results shows that the efficiency is 7.25% with 2 kW work gained.
