Abstract :

This paper presents comparative analysis between; experimental results obtained using a solar parabolic concentrator (SPC) model TE. 38 and simulated results obtained using a developed energy equations for solar parabolic concentrator. The experimental aspect employed SPC model TE 38, on to which a receiver assembly constructed with available sourced materials was mounted along the focal line. Hourly temperature changes of the enveloping glass-cover, the absorber-tube and the fluid are recorded and system efficiency calculated. Developed energy equations are used to predict hourly temperature changes of the enveloping glass-cover, the absorber-tube, the fluid and system efficiency. The developed energy equations are validated since the performance of the practical results and the predicted results R2 values are 80.4% for the enveloping glass-cover, 98.9% for the absorber-tube, 96.4% for the fluid and 98.2% for system efficiency.
