Uni-Solar & Class A fire rating [RE-wrenches]

[asap at podnine.com]

Although it may require you to educate the inspectors I bet PVL could get
done and permitted in San Diego County.  If you or anyone needs backup from
City of Oceanside or City of Santa Ana inspectors for shingles on plywood
substrates, let me know.

The SHR-17's UL gives the product a thumbs up as solar electric product and
as a Guide TFWZ "listed prepared roofing material" with Class C rating,
true.  I believe the SHR's have the itinerant ICBO ratings too...   But it
did come up and was called for and that UL was good enough for their
concerns on plywood/roofing paper substrate--they had more problems with
penetrations and wire collation afterwards.   I haven't seen the PVL's
actual UL...maybe it does say Class A?  What makes something Class C again?

For the PVL laminates on metal roofs:  CHALLENGE.  EDUCATE.

Matt T.?  PVL's anyone?  Any problems permitting UniSolar PVL's over
listings?

There's 211kW that I know of riding on that SD county interpretation, I
assume this was the new guy at County.  The old main dude went up to San
Marcos.  Maybe some form of punishment.

Mo,

On the installations we do here in Northern Calif. the metal roof
achieves a Class A fire rating by using a special underlayment
beneath the metal roof. I could check with my roofer and get the
specific info if anyone is interested.
