Andrew--Thank-you for your work to dampen the fire hysteria that's sweeping the
roofs of residential solar. Between the ridiculous setbacks (out here you'd
never see a firefighter on a house roof swinging an axe, but if so inclined,
they could go on the other side of the peak).
And now we need to install mythical products for de-energizing and
fire-protection racking. Unless the big leasing companies can beat back the
anti-solar "safety" club, rooftop residential is toast. PV leaders and
consultants have caved. A short time ago, a firefighter (what was he doing on
the wrench page anyways?) urged installers not to look at their bottom line and
take in the big picture.
That is exactly what you are doing in opposing these rules that are set up for
problems that don't exist. The firefighting and code making industries are big
bucks.
Let's see, wrenches and folks who write the code can't figure out what it says.
And in our county in PA, there are 90 different permitting agencies that will
be reading the same codes and ordering their interpretations before we get a
permit.
The real big issue is sustainability and climate change and we need to have a
society that embraces a rush to PV and not smother it with the love of safety.

Installation Guidelines"

Dear colleagues,
Rooftop real estate available for solar is of unparalleled and monumental
importance. As we head into our 6th great extinction the solar industry needs
to fight tooth and nail to gain 100% access to every inch of available roof
space. The fire fighting industry needs to adapt to solar, NOT vice versa.
In Oregon, one person, myself, stopped the 12 person BCD committee from
adopting the anti solar 3 foot pathway around solar arrays. The committee
would not listen to reason. I went to the governors office saying and showing
that if the Cal. Guidelines were adopted as code 100% of the roofs we had
installed systems on would be 100%illegal and unviable.
Yada yada yada, we got the Koyaanisqatsi Rule.
304.9.1 General Pathway Requirements Exception 1.1. Where the PV array does not
exceed 25% as measured in plan view of total roof area of the structure, a
minimum 12 inch (305mm) unobstructed pathway, shall be maintained along each
side of any horizontal ridge.
1.2. Where the solar array area exceeds 25% as measured in plan view of total
roof area of the structure, a minimum of one 36 inch (914 mm) unobstructed
pathway from ridge to eave, over a structurally supported area, must be
provided in addition to a minimum 12 inch (305 mm) unobstructed pathway along
each side of any horizontal ridge.
I still see this as a failure. I had 40% going into the final meeting and one
foot from the peak only on pitches greater than 4:12. But, by that time
everyone hated me soooo badly for holding such a hard lined solar centric
perspective, and for succeeding in going over their heads, it was all I could
do to get them to meet.
Unassisted in this battle I was exhausted and unable to follow the proceedings
to the end. And, in the end, a rafter span chart hostile to solar was thrown
in and now we are dealing with that.
Here is the link to the Oregon Solar Installation Specialty Code:
http://www.cbs.state.or.us/bcd/programs/solar/solar_code/100110_OSISC.pdf
The concept and good intentions of a statewide code were good. Unfortunately,
the task was left to folk who were not as friendly towards or knowledgeable of
solar as one would think would be asked to be part of such a noble cause.
