Chris,

You most likely recall, there was a thread here discussing special standing seam
attachment details required with the S-5 product.
With your weather, those might be critical for the roofers to follow, should you
go that route.

I was unaware of the white spotting from hail you've seen on the Unisolar
modules. Do you have any photos you could share?

Thanks,
Dick Ratico
