Abstract

One approach for temperature regulation of photovoltaic panels is to place an open channel underneath the panel. The panels are cooled by free convection and by radiation. A scale analysis and numerical study of this problem is performed to characterize heat transfer over a practical range of operating conditions and channel geometry. A generalized heat transfer correlation for combined convective-radiative cooling is developed for modified channel Rayleigh numbers from 10 2 to 10 8 and channel aspect ratios from 15 to 50. A system analysis suggests PV production will increase by 2 to 4%.
