The maximum values of the overall net mean wind pressure coefficients of the PV panels in the middle positions appear in the wind direction angle ranges of 15–45° or 135–165°, but their maximum values are all less than those of the first or last row of PV panels.
The first row at the edge of the array is the most unfavorable location, and its shape coefficient is recommended to be 1.3 (for wind pressure) or −1.25 (for wind suction), with subsequent rows of PV panels being appropriately reduced based on this value.
Experimental research can only analyze wind effects from a relatively ideal environment. To better understand the wind effects on large-span flexible PV structures, further field measurements should be conducted to verify the accuracy of the design wind load calculated from the experimental data.
Therefore, for a flexible-support PV array with a tilt angle range of 0–60° for the PV panels, in structural design, the overall shape coefficient of the 1st row of PV panels should be taken as 1.3 (wind pressure) or −1.25 (wind suction).
