R324.6.2 International Fire Setback

[jayrob]

New international fire 'ridge setback' says that you can be 18" to the ridge if the array is less than 33% of the ‘plan view total roof area’.

Just not sure if it means 33% of the roof plane that the array is on, or if it means 33% of the entire house??

Anybody have any clarification on this?

Thanks in advance!

I think total roof area is the entire house.

So if that's true then we now can do our solar layouts with 18" to the ridge instead of 3'.

Just hope the AHJ's understand this...

Still does not allow solar panels to be designed to replace the roof... which would be my ideal idea... no more roofing, just assemble solar panels with rubber gaskets between them to create a water proof bond.

Right. There may be a bunch of conversations in the short term. We're putting a big note about the July 1 supplement on our plans.

Just make sure your plans get approved before you install the system.

Good idea thank you!

Good idea thank you!

Getting approval prior to construction is a good idea when you do line side interconnections as well. Some AHJ's have some idiosyncratic ways of looking at them.
