PHOTOVOLTAIC POWER GENERATION APPARATUS

摘要

PURPOSE: A sunlight generating device is provided to improve generating efficiency by drawing an optimum generating point for transmitting to an inverter through MPPT(Maximum Power Point Tracking) controlling by string. CONSTITUTION: A solar cell array(100) is formed with multiple solar cell modules(110) being connected in parallel and in series. Multiple strings(120) connect the solar cell modules in series. A sunlight sensor(130) is formed on one side of the solar cell array. Multiple string optima(210) generate the maximum power of each string. A string control part(220) controls each string optima. Multiple inverters(300) convert DC power generated from each solar cell module into AC power. The multiple inverters are separated into the same kW capacity.
