Todd,
That is a tall pole. Hope those were back mounted and not the Solarworld 2.0
frames! How far into the ground did you go? With how much cement? Did DP&W
approve the engineering on that? My memory is they didn't approve TPM heights
much over 9'. The largest we've done are 15 module racks, b
the engineering called for 8" sch 80... and some super strong rebar in the
base. i subbed out the mount so dont have all the details easily accessible...
but if i recall, the hole is like 6' deep and 5 feet square. it seemed
inadequate to me, but it was engineered, so i guess good to go.

Troy,
Maybe adding additional support to the trusses would allow you to spread out
the Lfeet a bit more? ...but then there is still that added cost!?!
QuickmountPV for one, makes a pretty solid case that any roof penetration needs
to be flashed if the waterproof integrity of a roof is to be ma
Thanks for the pitch info, very helpful. Are you using a heavy wall
thickness on the pole? I thought with DP &W we could only go 6 ft out
of the ground without increasing the pole size or adding bracing.

I do not know what a gravity flashing is. Can you elucidate?
If you have adequate upload mounting strength and need more download
support, you can consider using additional L-fee that simply rest on the
shingles without penetrating the roof. We do that sometimes to take the

HI Todd;
That's very interesting. What roof pitch does that happen? I'm
guessing that at a step enough tilt, the frame damage is alleviated?
Also on your tall pole mounts what pole design do you use? I've tried
telescoping type, and guy wires on tall poles.

I have never had good results with roof mounted pv in our heavy (mount shasta)
snow area. the snow tends to creep down the glass and peel the bottom of the
frame off the module... and then the glass breaks as it has no support in that
area.
so, around here... i do pole mounts WAY up in th
Hi all,
We have been doing PV installs for years with L-feet and silicone without
problems ever. Even still, gravity flashings seem attractive in shingle roofs,
to provide a second level of security, and a more professional install (at
least in perception). But the cost of these systems in sign
