Abstract
This paper applies a new dynamical electrical array reconfiguration strategy on the photovoltaic (PV) panels arrangement based on the connection of all PV panels on two parallel groups to reach the 24 V requested by the considered load and providing a maximum output current by connecting in serial the two groups. If one of the PV panels or more is shaded, the connection of the other in the same group will be automatically modified to maintain the requested 24 V for each PV panel row. This dynamical reconfiguration allows also reducing the lost power, due to the shaded panel, by recovering this power from the reconfiguration of the other panels. As a result, a real time adaptation of switch matrix allows a self-ability to maintain a constant voltage at 24 V and minimum number of PV panels is switched off by isolating the effect of shaded panels. In addition, the proposed solution can also be applied for the dirty panel and identify the shaded, dusty and faulty panel.
