This paper introduces the concept of installing a small-scale organic Rankine cycle system for generation electricity in remote areas developing countries. The Organic Cycle Systems (ORC) uses commercial magnetically-coupled scroll expander, plate type heat exchangers and plunger working fluid feed pump. source ORC can be solar energy. A series laboratory tests were conducted to confirm efficiency expander power output system. Using actual data, exergy destruction on components assessed. Furthermore, results variations energy efficiencies with different operating parameters, such as evaporating condensing pressures, degree superheating, dead state temperature, inlet temperature pressure ratio illustrated. exhibited acceptable operational characteristics good performance under wide range conditions. 121 °C is expected deliver approximately 1.4 kW. In addition, cost analysis financing mechanisms installation discussed.
