Predicting the electrical yield of photovoltaic (PV) devices over long periods of operating conditions is essential for the cost assessment of projects. The presented modeling of a PV panel couples different physics using finite-element method, focusing on long-term operations under desert conditions. The coupled physics are: (i) the solar irradiance; (ii) the heat transfer within the module, influencing the temperature-dependent conversion efficiency; and (iii) its electrical yield. The thermal behavior of a PV panel and predictions of its electrical yield are investigated for several years of atmospheric conditions in Saudi Arabia, with elementary assumptions regarding the performance of the selected PV device.
