Joel,
The problem is not with the rating of the modules. It is with the way we
install them. The air gap is a problem. If HVAC systems were installed like
PV modules, they would have the same problem. There will be changes of some
sort coming in the next year or so. The IBC in 2012 will require
Hi Joel,
Trying to compare HVAC equipment to PV in a roof covering flammability
discussion is about the same as the proverbial apples to oranges. They are
profoundly different. I will even go out on a limb and say the the PV
industry lobbyists are probably foaming at the mouth more than HVAC
Hello Bill,
Thanks for the feedback. I need to learn more about this issue. I plan to
attend the October 15th SolarABC meeting after the LA conference. Is 2012
IBC draft available?
How can PV systems be classified, let alone fire-rated, when there is a
seemingly infinite combination of
Good points all,
Has anyone had an experience where you've seen new shingles and PV installed
at the same time, where the shingles became prematurely brittle beneath the
array, where you could say for sure it was PV's fault? I too have tried to
keep an eye on that, but I never can pin it on PV,
Hi gang. It seems to me that an upward sloping gap between the flammable
roofing materials and the PV modules would result in a chimney effect for any
fire in the roofing materials whether the fire is a result of the PV system or
not.
Combine that with the modules blocking access to a roofing
Wrenches,
I'm coming from a perspective of comparing beneath array areas to not
beneath array areas of the same roof. Regarding flammability, I don't
really care what the source of ignition is in this conversation. I prefer to
think that the PV isn't the cause, frankly. Would rather think in
Hi I forgot last summer I removed some modules that I had installed in the
1996? the roof had been damaged by hail. No damage to the modules, and the
shingles under the modules looked great, and they did not look or feel brittle
and the rest of the roof was beat up.

A 30-year-old PV installer fell to his death back in April at job site in
CA. He backed off of a roof accidentally and was not wearing any fall
protection.
I have the official report of the accident, but the multi-state
full-service solar provider that has approximately 650 employees was not
