Can solar panels withstand wind pressure?
Solar panels and arrays should withstand wind pressures specific to the location of installation. The 2016 edition of the American Society of Civil Engineers (ASCE) standard includes the addition of roof-mounted solar panels, but ground-mounted solar panels have yet to be added to the standard.

Can a photovoltaic panel be installed at 32 m/s?
The average stress at the panel surface at wind speed 32 m/s is 1415.6 Pa. At the wind speed, 42 m/s is 4379 Pa, and at the wind, 50 m/s is 15142 Pa. As a result, thin-film photovoltaic panels (maximum static load tolerance of 2400 Pa) cannot be installed at wind speeds greater than 32 m/s.
