[RE-wrenches] "Quick Release" PV System

[SOLARPRO at aol.com]

And to my knowledge, there exists no certified, listed or  approved 'Quick 
Release' mechanism, other than improvised hand-built solutions  that are 
approved in-situ by the Fire authority having  jurisdicktion.
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.

"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.
