I work as a process engineer Solyndra, I don't know if it is right for me to comment on this or not, but fighting bogosity is my hobby. Of course we did hail tests, I was involved. We shot homemade hail iceball out of a painball gun at our panels and confirmed that they could survive. Our panels have already been through hailstorms around the world. No tube breaks due to hail.
