shows the flat Fresnel concentration assembly considered in this study. It consisted mainly of flat Fresnel lenses, a modified cavity receiver covered with a flat glass cover. Tracking of the system was achieved by a stepper motor in which the motor’s tracking position could be controlled precisely without any feedback mechanism. This in turn, was integrated to a subdivision driver which was conpredicted using solar position algorithm developed by. The tracking system in present study was achieved by using a Microprogrammed Control Unit as a controller coupled with a stepper motor to conduct time-based solar tracking which was illustrated in our previous work (Lin et al., 2013).
