What if every 4 rows or so, you left extra space to hack into the
roof to ventilate? How big a hole do they need to cut and how often?

There is a hope of a possibility that a hinged mechanism will be
developed that will placate those fire officials wanting a way to
quickly ventilate a structure.

Chula Vista has been difficult on a number of fronts for the past
few years.
I'm not sure what is behind it. This is a reference from an old Los
Angeles
Fire Department regulation. It was invented by a person at LA who
still
thinks it's a good idea. I don't doubt that it could not be
developed. My
first roof bracket had a quick-release feature for servicing panels
in the
array. It is a bad mandate and was rejected by the group who
developed the
guidelines for PV installation with the California Fire Marshal's
office.
There is no state support for the idea.

Subject: [RE-wrenches] "Quick Release" PV System
"Quick Release" PV System
I just had a set of plans rejected by the City of Chula Vista, CA,
because
the integrated Tile product that we use did not have a "Quick Release"
System for the array, so that the Fire Department could remove the
array in
the event of a fire.
Has anyone ever heard of such a requirement? If so, how did you
meet this
requirement, with any style of PV array (BIPV, Standard Modules,
peel &
stick) and still achieve an 85 - 100 mph wind rating? Is it just
me, or is
this city from a different planet.
This issue did not show up on the initial Plan Correction check
list from
the city, but they are calling it out now when we re-submitted. My
electrician asked them to explain it to me over the phone, because
he did
not think anyone would believe him when he asked for this
requirement. I
have asked for a document or anything that defines this
requirement, and
will share what I find out.
