Seven different compound parabolic concentrating (CPC) collector designs were tested by the ray trace method. The comparison of the collector was performed by simulating sunlight striking the designs at various angles of the sun during the course of the day. All of the CPC solar collector designs used the same type of reflective material, Kinglux reflective aluminum, which is a highly reflective surface used in solar applications. The CPC solar collector designs were subjected to a light source consisting of one helium-neon laser. The laser, to represent the effect of sunlight on the stationary CPC solar collector, was slowly moved across the aperture opening. This is explained in detail. Mathematic equations were used to develop the different CPC solar collector designs. The different shapes for each collector design, were acquired by varying the size of the absorber tube, and also by varying the acceptance angle of the collector. The seven CPC solar collector designs were tested, and the optimal design was selected for experimental testing.
