William, The only framed modules I've seen with a non-conductive frame are BIPV modules. They were about 34W each and integrated with concrete roof shingles/tiles. I believe the frame was polycarbonate. We ended up removing a 6kw system of these because some of the glass started delaminating around the edges.
What about using Lumos frameless modules?
