What components does a photovoltaic power generation system consist of?

The photovoltaic power generation system consists of a photovoltaic array (a photovoltaic array is composed of photovoltaic modules connected in series and parallel), a controller, a battery pack, a DC/AC inverter and other parts. The core component of the photovoltaic power generation system is the photovoltaic module, which is composed of photovoltaic cells connected in series, parallel and packaged. It converts the sun's light energy directly into electrical energy. The electricity generated by photovoltaic modules is direct current, which we can use directly, or we can use an inverter to convert it into alternating current for use. From another perspective, the electric energy generated by the photovoltaic power generation system can be used immediately, or it can be stored in energy storage devices such as batteries and released for use at any time as needed. The system composition is shown in the figure below:
