Mathematical Model of a Hybrid Solar Panel

Hybrid solar panels are energy conversion devices that combine photovoltaic cells with an efficient heat exchanger. By circulating a cold liquid underneath a PV cell module array, the array is cooled, increasing its energy conversion efficiency, while also recovering excess heat. This paper describes finite element modeling work designed to investigate the increased collection efficiency that is possible when using hybrid solid panels. The model simulates fluid flow, heat transfer and energy conversion in a two-dimensional configuration with heat exchangers consisting of two parallel plates with and without fins. Results show that the fraction of the solar energy recovered is significantly higher when the heat exchanger is attached to the PV module array to produce the hybrid solar panel.Copyright © 2014 by ASME
