CPV panels transform only direct normal irradiance (DNI) into electricity, whereas flat PV panels can transform a more available source of irradiance, the global normal irradiance (GNI). In the event of a cloud or shadow cast on the panels, this leads to immediate interruption of the CPV production but a maintained production by PV panels. For CPV, this phenomenon is amplified by the grid-tied inverter which enters “stand-by” mode while the voltage available from the panels is not sufficient (<200V), and takes time to restart the power injection after the situation is back to exploitable irradiance. Therefore, the aim of this article is to determine whether a hybrid connection of PV and CPV on the same inverter could reduce the time of zero energy yielding, in order ultimately to inject more energy into the grid.
