【Abstract】 The design principle of the bending-plate type concentrating PV system was briefly introduced,and the optical model was developed for the reflector concentrator. The performance of the concentrator was simulated by means of Monte Carlo Ray Tracing Method( MCRT) and the results showed that the concentrated light of the system had a high uniformity. A prototype system was constructed,and the experimental results agreed well with the simulation results. The relationships of parameters of the bending-plate concentrating PV system and the effect on the concentration caused by sun-tracking errors were calculated and analyzed,and the results showed that the tracking accuracy for the bending-plate type concentrating PV system was of less demanding.更多还原
