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

[Jason Szumlanski]

That's based on ASCE 7-05. If your AHJ requires ASCE 7-10, that is no
longer the case. Florida Building Code 2010 requires use of ASCE 7-10, and
ultimate design wind speeds have changed dramatically, so it's important to
consider the method, not just the wind speed.

We liked Zep, except when you have to remove a module for service.
Microinverter installations are a little clunky with Zep, even with module
frames specifically designed for Enphase. Unfortunately, we stopped using
the product for a variety of reasons, not the least of which were new code
requirements in Florida.
