PV Rack on Slate Roof? [RE-wrenches]

[Jack D West]

Steve,

I have not installed any roof mounted PV's and stick stricktly to poles because of snow
accumulation.  I don't see a GFI for roof mounted PV's in my future.  I highly recommend
pole mounts for anyone in snow country.  Like Bob-O says, a solution looking for a
problem...
