Description

Technical Field

The photovoltaic power generation device connects multiple photovoltaic modules through connecting bolts and connecting plates according to the conditions of the installation site, and is convenient for disassembly and maintenance. The traditional solar cell panels are arranged in the air instead of on the ground, which reduces the floor space, improves the space utilization and power generation efficiency, and has strong adaptability. By opening a groove on the photovoltaic bracket and opening a through groove on both sides of the back of the photovoltaic bracket, convection is formed in the photovoltaic bracket, which facilitates the heat dissipation of the solar cell panel and ensures the normal operation of the solar cell panel.
