The influence of convective heat exchange on the temperature of a solarvoltaic array
Аннотация
The influence of convective heat exchange on the temperature of a solarvoltaic array (SVA) is studied. It is shown that the temperature of a SVA depends significantly on the wind velocity if the temperature of the environment is less than 30°C; the temperature decreases by 40%, while the wind velocity increases from 1 to 10 m/s. In this case use of a photo heat-regenerating unit is inefficient. If the environmental temperature is more than 30°C, then the change of the SVA temperature depends slightly on the wind velocity and it is necessary to cool it for the efficient operation of the SVA. At a wind velocity of less than 2 m/s the SVA is cooled both due to convective and radiation heat exchange. At a wind velocity of more than 2 m/s the convective heat exchange prevails over the radiation heat exchange.
