[RE-wrenches] "Quick Release" PV System

[Bill Brooks]

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.

 

Bill.

"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.
