What are the wind loads on the structures and panels and is this the same for the whole park and if there is a difference around the perimeter what is it. What is the maximum wind speed these structures have been designed to withstand. All help welcome

Peter, it depends on the location. Different areas have different loads.

Based on IEC standard, normally need to achieve 2400Pa minimum. Some area need 5400Pa for the wind load.

You need to calculate the estructure for an achievable speed on the place or regarding to the country rules or as Weiqian Hu said IEC standards.

I do the calculation for the worst conditions, so the first and the last row, traction and suction.

thank you all
