Definition: Flexible photovoltaic brackets use prestressed flexible cable structures (such as prestressed steel strands) as the main force-bearing components to form a large-span photovoltaic module support system. This bracket structure not only has a large span and clearance height, but also has. . The first reinforcement strategy involves increasing the diameter of the prestressed cables to 17. These configurations are named F1-1 and F1-2 for ease of comparison. sts of six spans,each with a span of 2. .
