jimmygoduh: You may be sure, but you haven't proven anything about PV glass solar yet. I am not laughing yet. Why are you trying to pass SOLAR THERMAL as a solar installation? Yes it is solar, but the context was PV solar, not THERMAL SOLAR.
We were discussing OpriSolar's contract, which is PV. Then I cited you IEC 61215, which covers PV. Thermal solar is not covered the by the hail tests from the IEC 61215. Where did you get the idea that were are talking about THERMAL SOLAR here?
So, why don't you provide some evidence that AT LEAST ONE PHOTOVOLTAIC solar installation in the WORLD has EVER been damaged by vandals throwing rocks. Then I will admit that my statement that "glass panels are vandal resistant" is quite funny and will laugh with you. Ok?
