Paper Abstract

We present a static concentrator system made up of refractional units for changing slanted sunlight to vertical light. The refractional units are cylindrical and were placed to face the sun over Taipei. We used meteorological data from the Central Weather Bureau in Taipei to define the collecting range of our system. Based on the vignetting effect and the loss of sunlight, we discuss the configurations of refractional units and compare their performances. For evaluating the performances, we define a parameter to evaluate the refracting capability.
