Cal Fire Setback Variance?

[Willaby]

I just wanted to post an update. My installer was able to get a variance to the 3' peak setback rule based on alternate venting availability. Because there are fire venting possibilities on the roof that are equally viable to the roof face with solar panels, the exemption was issued. So the setback rule is definitely not written in stone.

Same here. Variance was not a problem, right up to the ridge line. City Fire Chief's make the policy. Factors are: 1. panels can only be installed on one side of the ridge and 2. what's under the roof (living area or attic). For this I don't quite understand, but my panels are installed over the vaulted living area and the access is on the other side, over an attic area.

Getting the variance opened up a whole row of panel availability, 7 panels of prime production area.

I just read an article where Louisiana has recently adopted the 2014 NEC article 690 concerning fire set backs.

It also has a requirement concerning a manual disconnect within 5 feet of the array to protect First responders from getting shocked. So interesting changes for solar not only in CA.

I assume none of that applies to ground mount PV? Bruce Roe

I'm pretty sure the code applies to buildings that may require first responders to open up a hole to vent and need access to the peak of the roof.

I have to read the NEC again if there is any specifics for ground mount pv systems. Certainly there should be some type of disconnect somewhere in the circuit.

For a ground mount system they may just let it burn or bulldoze it under to keep the fire from spreading.
