This paper addresses the challenges associated with predicting the temperature of solar cells under operating conditions, which is crucial for optimizing performance and reducing the risk of system failure for PV system designers and operators. The conventional approach of estimating solar cell temperature using thermal models based on energy balance presents significant uncertainties, particularly with the convective heat transfer coefficient, which is difficult to measure and depends on various parameters. To overcome these challenges, this paper focuses on the measurement protocol for the convective heat transfer coefficient and the identification of the main influencing parameters. As reported in the literature, the results show a linear variation with the wind velocity within a relatively narrow domain of validity. The influence of two main parameters is investigated: the location of the sensor and the orientation of the panels with respect to the direction of the dominant wind. It should be noted that all the obtained results will be valid mainly for this particular analyzed situation: The bi-slope power plant configuration with panels installed in an east-west dual-sided format and a 12° tilt.
