Ray,
This is exactly how we installed many 10 and 12' fiberglass C-band satellite
antennas back in the 80's in Tulsa. None ever came down in tornado alley. I
recommend this method of pole mounting in Mexico due to frequent theft.

Drake,
Sorry, but I'm the wrong one to ask. I guess I wasn't clear: I
haven't done any off-grid adjustable roof-mounted arrays in
recent years. DP&W Power-Fab was the best I found way back when.

We too are suddenly faced with a requirement for an engineer's stamp

William,
In the photo that you attached to your post, while the legs were
nonadjustable, you had used the same UniRac Solarmount hardware that
is so problematic when set up to be adjustable. The twirl nut can
easily be loosened too far, until it loses its alignment in th
Another method I've used in the past, is to set a 20 ft pole right next to the
house in concrete, then attach it to the house or rafter tails with unistrut
and clamp. I'll usually use a 4 ft piece to spread the load out over at least
three structural members. Then the pole extends 4 to 6 ft abo

Or through it .. if it's even still there.

With the change to ASCE 7-10, the uplift calcs are not that much more,
and in some cases less, but I think in any case the concern is
wind-borne debris. If the mod stays attached to the roof, we are good.
Having lived through it, it's all theory anyway. In a hurricane,
theory goes out the window.
Many inland areas in California, Oregon, and Washington are 85 mph
zones. I think that's the lowest requirement anywhere in the U.S. I
can't imagine designing for 185 mph winds.
Doesn't that just blow the glass out of the modules?

Oh, to have 85 mph winds. Code changes just brought us up to 180 mph
design wind speeds in Southwest Florida. Yay.

William,
There are auger mounted systems that don't require any concrete. For
locations with suitable soil, they probably save some time and are a
little less expensive than concrete. But it takes a substantial
structure to withstand 85 mph, or greater, winds. There's no getting
around the ph

Thanks for the photos and description of the mounts you are installing. We
have installed many of the DPW ground mount systems in similar
configurations.

Are you sure they go up to 45 degrees? I looked at the web site this

We use Unirac ULA. Good quality. We have winter use only systems in Mexico so
we set the arrays high for best production in January. You should have no
problem with 45°.

Been using Unirac U-LA for years with HD Solarmount rails. Not the
cheapest, but I'm very happy with the product support and quality.
10-25 degrees is my range of experience, though.
