Description

Solar Photovoltaic Power Generation System

technical field

The invention relates to the technical field of energy technology development, in particular to a solar photovoltaic power generation system.

Background technique

Under the condition of light during the day, the solar cell modules generate a certain electromotive force, and form a solar cell square array through the series and parallel connection of the modules, so that the voltage of the square array meets the requirements of the system input voltage. Then the storage battery is charged through the charge and discharge controller, and the electric energy converted from light energy is stored. At night, the battery pack provides input power for the inverter. Through the function of the inverter, the DC power is converted into AC power, which is sent to the power distribution cabinet, and the power is supplied by the switching function of the power distribution cabinet.

The solar panel is an important part of the solar cell module, and the area and sealing performance of the cell are important parameters to measure the quality of the solar panel.
