In my business I see quite a few broken modules each year. As I recall, in every instance there is a visible point where the impact occurred. Typically a small radial pattern is around the impact point but then random patterns over the rest on the module. Look close. Hope this helps.

Turns out the module glass is shattered. There are no obvious (that i can see) impact points, leading to the question... Why did the glass shatter? I don't want to just assume, but if there is no sign of impact, I'm wondering if this could be a warranty issue? Frame expansion/contraction due to temperature swing maybe? Any experiences, thoughts or advice?
