Mismatch in solar arrays is caused by singular sources or as a combination of multiple smaller effects which supplement one another. Subpanel dc-dc converters have demonstrated the ability to handle mismatch in photovoltaic (PV) strings regardless of the source. This work will investigate the impact on power production of varying degrees of mismatch spread throughout a PV array. A comparison is made between PV strings with dc-dc converters and conventional strings employing bypass diodes. When mismatch is widespread, the power output of strings with dc-dc converters tends to favor the mean maximum power point (MPP) of the PV elements. Power output of strings with bypass diodes tends to be pulled down by low power outliers.
