If you're wondering should you worry about your solar panels in cases of extreme weather conditions, the answer is "no" — of course, up to a certain point. Every model of solar panels gets tested in STC (Standard Test Conditions). Not only its performance gets measured, a module is also tested to withstand extreme hails and harsh winds. Panels should be fine with the wind even at speeds of 100-120 mph if installed properly and modules can also withstand a hail at a speed from 20-30 m/s. If anything, solar panels even extend the lifespan of your roof by protecting it from water. Generally, rain takes care of washing solar panels but it is still recommended to perform cleaning of your panels once a year or their efficiency might drop overtime.
