Hello, Team~
I'm laying out some Sanyo modules on paper. Twelve of them fit the roof with
almost too much perfection: this would be difficult to install as it would
fill the roof edge to edge in both directions. Are there consistent
guidelines about the amount of roof edge which must remain
Most racking manufacturers have a minimum setback distance from the edges of
a roof for wind loading.

I train both fire departments and PV installers across the USA on PV
systems and firefighter safety. Covering the roof edge to edge as you
say is a very slippery slope for you, as the system designer. It's not
legal in many areas, where setbacks and access pathways for firefighters
are
Dan, let me start by saying that I am not trying to attack you here and that
I do appreciate the valuable and dangerous job that fire fighters have.
However, this issue is of great concern to me when it comes to the majority
of residential PV systems.
Since this is a residential, trussed

Mick, here in California the fire department in the various agencies has the
final say on clearances. There is a very clear cut standard in place for the
state, but we have been successful a few times in getting allowances to vary
due
to various site conditions. A call to the local AHJ is the
Using the HIP Sanyos then the area is really more like a 1/2 after you get
a fudge factor in there,~ 36' +/-for your 12 modules.
Sanyo's HIPs are good modules,, they have addressed the hi temp issues.
The only issue might be the cantilever from the mounting foot to edge of

Just to throw this into the discussion, maybe there can be exemptions written
into ordinances stating that if technical issues (system sizing requirements)
provide for less than sufficient setback, or walkway space, then maximum DC
system voltage cannot exceed 50VDC. In other words use
MIck--We just did a similar project as you describe where the edge to
edge clearance was
critical---used Pro Solar rails and tile tracs the minimum gap between
modules was more like
three-eights inch, maybe less. Their tech support was excellent as
well--and they seem to have mid and
Brian;
I think you laid out the challenges quite well. Keep firefighters safe,
but don't pose unrealistic constraints on PV systems.
You also mention true accessibility -- which is a big issue here.
