[RE-wrenches] Best racking systems (was Awkward Mid-clamps & jigs for installing or removing modules?)

Sat Jan 19 14:52:25 PST 2013

Chris - The Zep system can be installed in up to 150mph wind zones in most
cases.  See the span tables on the Zep engineering documentation:
http://www.zepsolar.com/images/files/general/pdf/ZS_Compliance_Letter.pdf

Todd - Ground snow loads of up to 70 psf are allowable.

A free design tool can be found at zepulator.com

"Don't get me wrong: I love nuclear energy! It's just that I prefer fusion
to fission. And it just so happens that there's an enormous fusion reactor
safely banked a few million miles from us. It delivers more than we could
ever use in just about 8 minutes. And it's wireless!"
