PTP,
What is TSP ( ) wash and rinse? Sounds like YAYOQ (you answered
your own questions). We have a CC (common circumstance).
I'm hoping TSP is some sort of not-totally-toxic chemical bath that will eat
away the anodization quickly and efficiently, and simply wash off into ??.

Thanks again, Bill,
I'll investigate PVSYST also, as I can't get PV Watts either version to work
for me online beyond 4.0kW(?) and no data points for new zip code anyway,
and in old zip code, NREL's map servers seem to not like me in any browser.

suddenly start requiring fused DC disconnects? Typically, we fill the fus

Agree with purposes 1), 2). You'll have to continue patiently educating
both AHJ's and utilities meanwhile. Most likely you would have to show the

Jeff,
I agree with your points certainly. As Rebecca Eaton had also pointed out
however, it's really just a matter of time. Or timing. And patience on the
part of all of us, early adopters that have gone the extra mile, and eager
newcomers alike.

Both area and cost per kw are going to depend on the PV technology platform

Jeff, excellent questions. Also, how many clips per say, 100 or 1000 ft of
clipped-on ground wire are recommended? Is the distance in between clips
per code or certification of the clip in any way? Does anyone have a cost
per linear foot comparison between lug+bare+labor and sliced bread?
