The function of the bracket is to protect the photovoltaic modules to withstand 30 years of damage such as sunlight, corrosion, and strong winds. Professional product design makes the solar photovoltaic support system can be assembled with only a few accessories, no other drilling or welding is required, and it can also be assembled quickly on the construction site, which effectively improves the installation efficiency, but also shorten the construction period.

The roof support adopts hot-dip galvanized carbon steel support, and the components are installed on the aluminum alloy purlins by means of backboard or pressing blocks. Fasteners are made of stainless steel. The bracket is designed with a wind resistance of 30 m/s to ensure long-term outdoor use.

Distributed photovoltaic power station for photovoltaic support equipment and technical requirements

When choosing solar photovoltaic brackets, you can see products made of different materials. The brackets made of aluminum alloy and the brackets made of stainless steel have higher practical application value, and brackets of different materials can be used There are also certain differences in time and installation methods, which can meet the application needs of different places and regions
