In a recent investigation, Tanner et. al. addressed the hypothesis that a sunlit photovoltaic (PV) panel should experience a drop in temperature if an electrical load is placed across it, because part of the sunlight energy would be consumed by the load, leaving less thermal energy at the panel’s surface. Their measurements confirmed that hypothesis; they saw a 3-4 ° C drop in a loaded panel relative to an identical unloaded panel. But when they added additional electrical load to the panel, expecting to further decrease its temperature, they observed instead a 1.0-2.0 °C rise in the panel surface temperature. Our purpose here is to explain this unexpected result.
