<div dir="ltr">Wow Lars.....<div>setbacks and signage are ICC 2012, and auto rooftop discos NEC2014, where did this Class A bus you got thrown under come from? It's not ICC or NEC from what I can read.</div><div>Is there an SEIA person on this list?</div>
<div>Pretty much every install I do here in Colorado is wildland/urban interface. We dont do many roof mounts as rural folks generally have lots of land for a ground mount, but wow. As a firefighter, who also makes a living teaching solar power firefighter safety classes, requiring class A doesn't make sense and provides no safety benefits to firefighters or homeowners. Analyzing incident reports and going on service jobs, I see the combination of physical movement of conductors against rough services (heat expansion and contraction, wind etc) and debris buildup (pine needles, leaves) under rooftop PV mounts as the big issue, with animal damage coming in 2nd. </div>
<div>Most homes burn down 0.5-3 days AFTER the flame front has moved through, thanks to windblown firebrands (embers) lodged in wooden nooks and crannys of the home. A plain plywood exterior wall can withstand a 100 foot high flame front 100 feet away without igniting. This is all proven, tested and videotaped. If the roof starts to burn from a firebrand......the fire rating of the PV modules themselves is meaningless.</div>
<div><br></div><div>Arrrrgh. I'm thankful for this list, please keep it in the loop here or email me personally. I am making major changes to my firefighter safety / outreach class this spring and need all the info I can get. </div>

<div dir="ltr">Wrenches,<div>If you are in a wild land fire zone in CA, it looks like we are all in for a rude awakening. Our local AHJ is requiring not only set backs for ventilation of roofs, but also THAT ALL PANELS ON THE ROOF CARY A CLASS A FIRE RATING! It doesn't take allot of research to realize that this pretty much eliminates roof-top solar as an option, as if you can eve find a class A panel, they are cost prohibitive. I'm wondering a couple things. One, has anyone had luck using the local political process to postpone the enforcement of the class A requirement? and two, has anyone found readily available Class A modules?</div>
<div> This issue seems to have caught the industry with it's pants down, as industry lobby doesn't even seem to be aware that the the local AHJ's would have this interpretation. Is this the end of roof top solar in 60% of California? What are y'all doing to deal with this issue?<br clear="all">
