Dave,
If the AHJ is happy with the remote power down of the inverter (and now
the PV array if on the roof or if it enters a building other than a
power shed) I'd say that's great. You can't make the inverter much safer
than shutting it down. A remote battery disconnect may only de-energize
an
I agree, Ray. Shutting down the inverter's ac output and the PV array is
sufficient to make a battery based system about as safe as possible for
firefighters. That is probably what was wanted when the code was revised
to require an outside battery disconnect. Unfortunately, the local AHJ
may no
I don’t think it is a good idea to install systems on shake for almost too many
reasons to list. I suggest re-roofing that section of roof with almost
anything else. If only reroofing that section the solar is going on in order
to prepare the roof for the solar it may qualify for the ITC. But
Interesting idea: shutting down the inverter should actually be
preferable to a battery disco, since its possible to disconnect the
battery and still have an inverter operate array direct if the loads are
close to the array output. I've seen it take several minutes for the
inverter to shut off

We will not go over a shake roof, we will only strip it and comp the area
of the array and shake over the comp AKA picture frame it in. Leaving the
shake in place is asking for trouble down the road.

QuickMount flashings for shake 👍
Be careful when sliding the flashing in and make sure you get it under the
underlay paper. If you’re not careful you will hit the paper and bunch it up
and it it a bugger to flatten out the paper if that happens.
The uneven surface is something you need to deal w
Thanks Kent,
A question, most of the Sierra AHJ's only care, and that
is rare, that there is a remote power off like Outback and Schneider have
already. I understand it is not a battery disco, and even though there is
one in these systems, what is your response please?

Hi Howie,
We bump into wood shake roofs from time to time in the Bay Area. I second
what others have said. In particular, make sure the roof is not too old. We
have a cutoff of 10 years old or less in order to consider
self-waterproofing the install. Otherwise, we insist on roofer engagement.

Hi Howie

Damage to the shakes not under the modules during installation, walking all
around etc. if they are old and brittle it’s going to be a huge problem as
they will break quite easily.

My experience here in Virginia goes back to the last century- -- ouch!
Thermal panels mounted with space under. Squirrels chewed a big hole all
the way thru the roof into the attic !

This can be a tricky installation as the shingle has a bevel that
asphalt does not. Quickmount just uses a larger flashing piece to my
memory, which is not very helpful. Chris Warfel

Howie,
I’ve had luck with the Quick Mount attachment made specifically for cedar
shake. More tinker involved than a regular asphalt roof, but a good option
to make the job work.

Hope this helps.

Hi all,
Does anyone have any experience mounting on a roof with cedar shakes. I'm
most interested in figuring out how you can avoid breaking half the roof
apart and still get trail and panels mounted and wired.
Thanks for any ideas,
Howie
