Wind load on solar PV panels Wind load can be dangerous to solar PV modules. Severe damage might occur if the solar PV panels are ripped from their mooring. This applies not just to solar PV modules erected on flat roofs or ground-mounted systems, but also to solar PV panels on sloped roofs. Wind load can have a significant impact on them.
Wind force pushes up from the gap underneath the panel between the panel and the roof, creating turbulence against the ballasts and weights designed to resist the wind.
Wind speed (at a height of 10 meters) / 1600 = pressure load Wind load on solar PV panels Wind load can be dangerous to solar PV modules. Severe damage might occur if the solar PV panels are ripped from their mooring.
In many cases where the wind has created lift under the panels, it is often the roof itself that is damaged and not the panels. Solar panels will experience wind force that pushes down on the panel from above and pushes up from the gap underneath the panel between the panel and the roof.
In the case of the wind suction effect, the distances between the solar PV modules and the roof surface, as well as how near the solar modules are installed on the roof's edges, are critical. Wind pressures can be significant, particularly in the gables and at the roof ridge.
During severe storms like hurricanes and tornados, it is more often the roof itself that is ripped off, taking the solar panels with it, and very seldom do the panels themselves come loose from the mounting racks. Panels are usually mounted at least 11″ from the roof edge to reduce and prevent excessive wind loading.
