Design and simulation of solar parabolic trough with trnsys

Pakistan is an energy-starved country and this demand of energy is increasing with every passing day. Fortunately, the country receives ample amount of annual solar radiation which if utilized proficiently and effectively can suffice the domestic as well as the industrial needs. In the present study, a design of 20kW parabolic Trough is proposed. Results of theoretical calculations have been given in detail and the design has been analyzed on TRNSYS software. The resulting graphs well describe the variations of various outputs of the solar field and help to predict the performance of the plant. (author)
