When the wind blows across a roof with solar panels, it passes through the small gap that typically exists between the panels and the roof (or between your panels and the ground in the case of ground-mounted systems), causing a large amount of uplift to the panels.
The weakest link for the wind resistance of a solar panel system is rarely the panels themselves – in most instances where wind causes damage to a solar array, failures occur due to weaknesses in the racking system or the roof the panels are affixed to.
Another issue that individuals are concerned about is whether or not severe winds would harm their solar panels. Another aspect that may add to damage in a storm is wind. High winds from all directions may wreak havoc on even the best-built houses. Uplift may be an issue since the solar panels are placed slightly above the surface of the roof.
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.
In the most extreme cases, solar panels may stay anchored down, but uplift from strong winds can tear sections of your roof off. Cases like these show that a well-built solar racking system may be more resistant to high winds than your roof itself. Another potential source of panel damage during wind storms is flying debris.
“The value resilient power systems can deliver in the face of severe weather events and after their impacts is ever more important. Severe weather-prone regions could benefit from resilient solar PV,” the authors conclude. “To be effective as a resilient power solution, though, the system needs to survive the weather event.

What to do when your PV system has been damaged by a storm
PV modules get torn from the system or blow away. Depending on the wind power (wind, storm or hurricane), photovoltaic modules can be torn out of their anchoring or complete systems can be swept off the roof. The reason for this can be the intensity of the wind. Even the best system can give way in very strong winds. However, it can also be due ...
