For what it's worth, you may want to check with the rafter mfgr and/or Eng as
it is possible they will not allow holes being drilled into them and you could
open yourself up to liability issues.

William,
With Tech90 regardless of the conductor size it always comes with a bare #8
included. A 3 conductor #10 (aka 10/3) will have red, white, and black #10
plus the bare#8.
A four conductor will have red, white, black and blue.
I have only ever seen or been made aware by my suppliers
always included and are available in different
sizes, to an extent.

If you are relocating the vent and abandoning the existing hole then could you
not just cut the vent flush to the roof or cut it right out and slide a

I was asked... What is the minimum Lux level required to make usable
electricity with a commonly installed monocrystaline PV module.
The question is for the purpose of designing a tracker that will not operate
until a particular threshold is reached.

I believe there is an issue with connecting the GFX (or GVFX) to just any
generator, such that Outback recommends or perhaps requires (warranty reasons?)
that the only generator that can be used is a particular Honda generator. The
EU series maybe.
A real down fall of the GFX's.

Jesse,
Can't imagine there is a definitive answer. The further the better.
Given what you are venting out of the battery box (very light hydrogen gas) I
would at the very least make sure the battery vent is higher up than the
furnace intake.
Any other sort of barrier btwn the two vents,

A good decision can be based on, among other site/load specific details, the

Would it not be a more straightforward approach to just size the strings,

you can purchase L-foot brackets of varying heights upwards of 7 from several

You are not limited by the height of the flashing bolt or post.

This won't help with the height issue, but maybe you could trim the flashing

Or is it possible to access the underside of the roof beside the skylight so
