Solar power generation system and method

A power generation system (210) includes photovoltaic (PV) modules (212) for generating power and power converters (214) coupled to receive power from the PV modules (212). The power generation system (210) further includes converter controllers (222) to control the power converters (214), each converter controller (222) includes a maximum power point tracking control element (221). A master controller (224) in the power generation system (210) is configured to coordinate power outputs of the power converters (214) by controlling the timing and numbers of power converters (214) having power-voltage (P-V) curves sweeping between maximum power points and power points off the maximum power points.
