There are many structural forms of photovoltaic brackets, one of the common structural forms is the photovoltaic grid structure, which is a spatial rigid structure composed of multiple rods and nodes. The photovoltaic grid structure has the advantages of lightness, good rigidity, strong bearing capacity, and strong wind resistance, and is suitable for photovoltaic power generation sites with large spans and large areas.
