Paper Abstract

We demonstrate 3D-printed nonimaging concentrators and propose a tracking integration scheme to reduce the external tracking requirements of CPV modules. In the proposed system, internal sun tracking is achieved by rotation of the mini-concentrators inside the module by small motors. We discuss the design principles employed in the development of the system, experimentally evaluate the performance of the concentrator prototypes, and propose practical modifications that may be made to improve on-site performance of the devices.
