Abstract: The design method and its working principle of a sliding linear Fresnel solar collector are presented. When the true sun was from 10:00 to 14:00, the optical path simulation of the collector was performed in TracePro, so the change of the spot in one day was obtained and compared with the experimental results, and finally the annual spot simulation analysis was performed. The simulation and experimental results show that the two curves are basically the same, and they both show the parabolic symmetry law of increasing first and then decreasing. The average collector efficiency of one day is 22.90%, and the simulated equivalent average heat collection efficiency 24.45%, the average heat collection efficiency without slip 6.40%.

Key words: solar energy, slip type, Fresnel, collector, collector efficiency
