The paper outlines the experimental set up as developed in order to obtain measurements and determine the power performance of a PV array, its efficiency and the temperature on its surface. The investigation covers a PV array system placed in a free environment, outdoors. The experiments were carried out for different inclinations of the PV panels and various levels of solar radiation on them. The paper provides an analysis of the results and argues about the coefficient which relates the PV panel surface temperature with the solar radiation intensity on it, with the angle of inclination, α, as a parameter.
Additionally, there are presented the results of the rate of change of the PV power output and its efficiency with respect to the solar radiation intensity for various angles of inclination, related to the air flow type and pattern at the back surface of the PV panels.
