Overirradiance and extreme overirradiance events have recently attracted the attention of the photovoltaic community since, if the inverters have not been properly sized, they can be overloaded and affect the operation of the protection systems installed in photovoltaic generation plants, causing potential damage and economic losses. Simulation models have been applied with little success in understanding the mechanism of overirradiance events since their estimates differ significantly from experimental data. Although these events were recorded more than half a century ago, the conditions for their occurrence still need to be understood. There are two hypotheses: the first states that these are produced by reflection at the edges and sides of thick fragmented clouds, and the second indicates that they are due to strong forward Mie scattering in thin clouds. This work tests such hypotheses using spectral irradiance data from spectroradiometers and satellite data of cloud optical depth. It is demonstrated that the impact of overirradiance events on the spectral distribution produces a red-shift, that the most significant increase in irradiance occurs in the infrared region, and it is determined that thick fragmented clouds are present during these events. It leads us to conclude that thick fragmented clouds are favorable conditions for overirradiance events and that they are due to reflection at the edges and sides of these clouds. Furthermore, the increase in global irradiance is due to the increase in the direct component. Finally, considering the impact of overirradiance events on the spectral distribution could help improve current simulation models.
