The modern day solar panels have adequate safety features and are very unlikely to be damaged by a hail storm. However, in rare cases, a direct LIGHTNING strike might CAUSE considerable damage to the solar panels. But the risk of a lightning strike can be mitigated by the INTEGRATION of an external lightning protection SYSTEM with the solar array. 

During a storm or a cyclone, the panel gets damaged only if the SURFACE on which it is mounted collapses. In areas prone to cyclones and storms, special consideration should be given to building strong foundations for the installation of a fixed panel. Also, as a precaution during storms or cyclones, the array should be kept horizontally at 180 degrees so that minimum resistance is offered to the wind.
