A solar powered cogeneration system is presented and investigated in this research. Linear Fresnel solar collector is integrated with proposed system to provide the required heat energy for dual organic Rankine cycle (ORC) in order to produce electricity and cooling load. The cooling effect is utilized to liquefy natural gas. The energetic and exergetic performances of the system are evaluated by varying the major design parameters. According to the results, the energy and exergy efficiencies of the system are found to be 14.3% and 7.1%, respectively. Furthermore, parametric optimization indicates that the amount of liquefied natural gas(LNG) has the maximum positive effect on the energy and exergy performances within 6.22% and 4.7%, respectively.
