Paper Abstract

Rooftop high concentration photovoltaic system is an attractive alternative to silicon panels in applications where high efficiency is imperative for limited roof space. Due to the in-panel integrated 2-axis tracking structure, limited heat dissipation makes it a significant challenge to keep solar cells cool. Finite element analysis modeling is carried out by taking into consideration of conductive, convective, and radiative mechanisms. Dominant thermal path is identified. We will show that, with improved designs, solar cell temperature can be reduced by more than 20C. Experimental results are used to verify the model and to improve thermal design.
