This study investigates the performance of a Fresnel lens solar concentrator system for solar concentration applications. A 300 mm x 300 mm polymethyl methacrylate Fresnel lens with concentric grooves of 0.24 mm height and 1.82 mm thickness was used. The lens’s geometrical profile was analyzed using a micrography observation approach to gain a better understanding of its geometry profile. Experiments were conducted with variations of operational parameters such as transversal and incidence angles. Trials were conducted at coordinates 6°02′04.8′′N 116°07′24.4′′E, between 1130 to 1330 hours, focusing on two major operational parameters (transversal and incidence angles). The receiver surface temperature was continuously recorded during the trials to determine solar concentrator heat energy gain. Both transversal and incidence angles had a significant impact on the system’s heat energy gain. The optimal configuration with lens transversal and incidence angles set to 90° and 5°, respectively, resulted in the highest heat gain of 8 kJ, achieving a concentration ratio of 16.42. These findings demonstrate the promising potential of Fresnel lens solar concentrators for practical solar concentration applications.
