I would have to agree, Silicon is building a manufacturing plant here in Northern MN, all of the studies I have seen show it would hold up to heavy snow loads.  Also the module does not have a "frame" on the bottom, so that would stop frame peeling.

There is no frame on the lower and upper edge which helps snow slide off and they are laminated with thick Sentry glass by Dupont which is typically used for hurrican and bullet proof glass.  We tested one with 3600 lbs of sand bags on it and 6 guys jumping up and down on it before we finally broke it. They have an interesting frame that contains the wiring and is accessible from the front.  I also agree that a steeper angle and somewhere for the snow to pile up is essential.
