| Abstract |
The output power of the partially shaded photovoltaic (PV) array is greatly reduced due to the blocking of the direct sunlight, and the current difference between the shaded and illuminated PV modules. For increasing the efficiency of the partially shaded PV array, a new configuration using an electromagnetic relay is proposed. This configuration is mainly used for collecting all currents of the shaded modules using the contacts of the electromagnetic relay. Therefore, the shaded modules in the new configuration delivered more output power with creating only one peak on the PV array characteristic for proper and simple functioning of the maximum power tracker. The simulation and experimental data validate the effectiveness of the new configuration for the power recovery of the partially shaded PV array using only an electromagnetic relay. |
