Various projects have been developed to use solar energy and some of them are in the course of developing all around the world. In Iran a 250 kW pilot solar power plant is constructed using parabolic trough collectors from 2001 to 2006. Results of thermal tests of the plant leads to the generation of steam with 250 oC temperature and 2 MPa pressure. Based on several years of experiments (from 2006-2010) it is decided to expand the solar thermal power rate to produce 500 kW electricity by combining the present system with a larger size collector and an auxiliary boiler. This article; explains the thermal design of the new collector and then various design options for combination of the new collector to the present plant have been studied and the most practical method of producing 500 kW is selected applying first law of thermodynamics utilizing a hybrid system.
