The invented solar panel is a series of connected solar cells coupled in a layout that substantially reduces the amount of mismatch caused by an imbalance in solar irradiance between the sub-module strings. Within the system lies a switched-capacitor DC-DC converter with a plurality of conversion levels. A conversion level is selected to provide the maximum power current of the solar cell in order for the converter to increase overall array tracking efficiency. Also included is a grid-tie inverter for coupling a PV array to a power grid. The inverter ensures the system operates stably by relying on feedforward rather than feedback processes.
