Photovoltaic brackets are usually made of weather-resistant metal materials, such as aluminum alloy or galvanized steel. These materials have good corrosion resistance and can be used in harsh outdoor environments for a long time. The structural design of the bracket takes into account factors such as the weight of the solar panels, wind load, rain and snow load, etc. to ensure that the system remains stable under various weather conditions. There are many ways to install photovoltaic brackets, which can be divided into two categories: ground installation and roof installation. Ground installation is suitable for large photovoltaic farms, while rooftop installation is common in residential solar power systems. The adjustable design of the bracket can also be adjusted according to the angle of the sun to maximize the efficiency of the photovoltaic panels in receiving sunlight.
