Abstract: A combined non-tracking concentrated optical (CNTCO) system composed of line Fresnel lens (LFL), reflection-type secondary optical element(R-SOE) and total internal reflection prism (TIRP) was proposed due to the high failure rate and high cost of the automatic solar tracking system. Moreover, the principle and design method of each component were discussed. The structure of the system was optimized and simulated in optical design software Zemax. The results show that the average concentration efficiency of the system reaches up to 24.1%, an 18.7% increasement compared with a combined system consisted of LFL and R-SOE (FRS), on the condition that the pitch angle is up to 16. The non-tracking concentrated photovoltaic module based on CNTCO system was integrated and preliminarily tested. The test results indicate that the photoelectric transformation efficiency of the module could be optimized up to 19.6% on non-tracking condition, even still up to 5.9% after 4 hours.
