摘要：Solar energy is currently represents the most abundant inexhaustible, nonpolluting and free energy resources that could be used economically to supply man's increasing energy demands. This paper presents the experimental performance study of a parabolic trough concentrator, which was constructed and investigated under climatic conditions of Dundaye at Sokoto Energy Research Center, Usmanu Danfodiyo University Sokoto, Nigeria. The collector was constructed using locally available materials with design parameters as: Focal distance of 0.15m, 1.82m length of the collector and depth of the collector as 0.33m.The experimental test conducted to evaluate the collector showed that the maximum outlet water temperature attained was 110℃, which is fairly acceptable, considering that it was an attempt to use local materials. Even though it encountered some problems such as inaccuracy in tracking the sun since it is manually tracked. However, the results obtained have shown that the temperature achieved is almost equivalent to the temperature at which the matter changes from liquid (water) to gas (steam). In this case it can be said that when appropriate tracking mechanism is used, this collector could be used for steam generation which can turns steam turbine for electricity generation.
