The photovoltaic power generation system consists of a photovoltaic array (composed of photovoltaic modules connected in series and parallel), a controller, a battery pack, a DC/AC inverter, and other components. Let's take a detailed look at the structural composition of photovoltaic power generation:

1. Solar cell modules.

A solar cell can only generate a voltage of around 0.5V, far below the voltage required for actual use. In order to meet the needs of practical applications, it is necessary to connect solar cells into modules. The solar cell module contains a certain number of solar cells, which are connected by wires.

2. DC/AC inverter.

A device that converts direct current into alternating current. Due to the direct current emitted by solar cells, the load is usually an alternating current load, and an inverter is essential. According to the operating mode, inverters can be divided into independent operating inverters and grid connected inverters. Independent operation inverters are used for the independent operation of solar cell power generation systems, supplying power to independent loads.

3. Design of power distribution room.

Due to the lack of batteries, solar charge and discharge controllers, and AC/DC distribution systems in grid connected photovoltaic power generation systems, if conditions permit, the inverters of the grid connected power generation system can be placed in the low-voltage distribution room of the grid connection point; Otherwise, only a separate low voltage distribution room of 4~6 m2 will be built.
