Abstract

A computer program, based on the equation of unsteady state temperature distribution, has been developed in order to measure the heat distribution in the bi-glass encapsulation silicon solar modules. The effect of such parameters as wind velocity, ambient temperature, solar radiation, solar cell efficiency, cell and glass thickness are investigated to determine the influence of each on the heat losses from the module during its operation. The cell efficiency decreases when the instantaneous solar radiation and wind velocity increase. The effect of the glass thickness on the cell efficiency has been shown to be considerable. The cell reached a steady state temperature of 45 °C after 115 s from the beginning of the cell operation at an ambient temperature of 20 °C.
