[RE-wrenches] Leaving metal roofs?

[Jason Szumlanski]

On a recent S-5 job we were allowed to penetrate the roof for conduit.
We used an LB fitting and an EPDM boot. The 2" LB does not stick up
above the modules when using S-5's and SolarMount rail. I would expect
that the LB would be higher than modules if using the S-5-PV, even if it
were smaller conduit. One way to make it look better is to use a 90 to
make the LB parallel and close to the edge of a module.

The roofer may want to do the penetration just to give himself a warm
fuzzy. It's no different from a plumbing vent, so most roofers won't
have any problem with it if you explain what you are doing.

Both SolaDeck or a weatherhead will work, I've used both. But if the
array
is mounted to S5! clamps the roof owner may not want any penetrations.
But
then they will have to deal with an unsightly conduit running across the
roof & around the eave.

All,

What have people found to be the best way to get PV conductors off a
metal
roof?  The last one I worked on I entered the building through the wall
using LB's.
