Ground Solar Brackets mainly depends on the arrangement and spacing of photovoltaic modules. The photovoltaic module array requires a certain distance from front to back, left to right, and the land area not only refers to the projected area of the photovoltaic modules on the ground, but also includes the gap area between the arrays. The larger the distance between the front and back of the array, the more land area it occupies

Specific calculation method
Taking a fixed photovoltaic array as an example, assuming there are 10 rows of brackets, the components on the brackets are vertically installed in double rows, and there are a total of 44 components on a single bracket. The component is 1.65m long and 0.99m wide, with a slope length of 3.32m between the two components in the upper and lower rows. The distance between adjacent components is 0.02m, and the distance between the brackets is 7m. The installation angle of the component is 37 °. So, the lateral length of the component array on a single bracket is 22.2m (44 ÷ 2 × 0.99+(44 ÷ 2-1) × 0.02), and the land area of the component array is 1457.5 ㎡ (22.2 × 7 × 9+22.2 × 3.32 × cos37 °)

Differences in Area Requirements for Different Types of Brackets
Fixed bracket: suitable for areas with little change in lighting angle. Its structure is relatively simple, mainly composed of columns, main beams, purlins, foundations and other components. The land area of the fixed bracket is relatively fixed, mainly depending on the arrangement and spacing of the components

Tracking bracket: By real-time tracking of the sun's position, actively adjusting the orientation of components to maximize the utilization of solar radiation, thereby increasing power generation. The maximum land area occupied by the north-south and east-west photovoltaic arrays needs to be calculated based on the longest shadow duration

Selection of Materials and Structural Forms for Stacked Scaffolds
Common photovoltaic bracket materials include aluminum alloy (Al6005-T5 surface anodized), stainless steel (304), galvanized steel parts (Q235 hot-dip galvanized), etc. Aluminum alloy brackets are lightweight and easy to install, but have low load-bearing capacity; Stainless steel brackets perform well in harsh environments but have high costs; Galvanized steel parts have good cost-effectiveness but are relatively heavy in weight

Choosing fixed, adjustable inclination, or automatic tracking brackets based on application scenarios can optimize land area and power generation efficiency.
