[RE-wrenches] grounding on metal roofs

[glenn.burt at glbcc.com]

Depends on the seam profile. Same device may be used in many cases. We have Also drilled and used the standard direct burial lugs on the underside of the pans, at the wave when they hang over enough to get working space. Then a horizontal run of copper wire to connect.
Don't be lulled into thinking that S-5 clamps are listed for grounding roof pans - they are not. They are only listed for module bonding to ground.

    We use the Ilsco SGB-4 ground lug on every pan under the array for residential systems.
