Jerry,

In your area of the country, you can use the PSP. In snowy areas (or any
area you want to elevate the area above the ground by a couple feet or
more in the front) you need to use the UniRac ULA system with 2" pipe.
>From what I know, both systems work fine, just that 2" pipe lets you
have a longer pipe sticking out of the ground, whereas 1 1/4" pipe does
not have enough bending strength to take the longer lengths.

Jerry,

I'd go with Stan Ulman and his Professional Solar Products ground-mount
hardware (www.prosolar.com).  Stan has done all the necessary
engineering for his mounting hardware and is a very helpful guy to deal
with.  (And, no, I don't work for PSP.)  Aside from the anodized al.
rails and other hardware he supplies, you would be using 1 1/4" gal.
pipe as posts sunk in concrete every 10'.  His phone: 800 847-6527.

aloha,

Wrenches,

I need to quote a PV system with a ground rack on the side of a hill.
I'm thinking about going with a pre-engineered system like Unirac to
save time both with design and installation.  Does anyone have
experience with Unirac's large ground rack product or anyone else's for
that matter.  Basically, I'm looking for opinions pro or con using a kit
system for this application vs. building our own with galvanized pipe &
strut.

cheers,
