[RE-wrenches] Looking for insulated #8 bare standoff

Wed Apr 18 18:06:33 EDT 2018

According to our state plans examiner; all modules, module rails shall be bonded. The array Tech tracker is not on their approved list of self-grounding racks. It is a 3-4 product list. Initially I was told I was going to have to remove the trackers.  Since then they have mellowed a bit.

We live in a narrow canyon & that extra 32% makes a significant difference in Nov-Feb. We did not have to run the generator once this winter & never went below 89% full.

Tracking really does not pencil out with todays price of modules. In tight canyons, with narrow winter windows and a lack of array mounting space make trackers an excellent choice. I am not an advocate of roof mounted PV in snow country in general though that’s where most of it goes.

There is something that is sexy about trackers too, they are like a magnet for interested clients.

Thanks for the suggestions folks I ordered the insulated loop clamps.

You should not have to run a EGC/GEC along the with Array Technologies. When I have installed these in the past we always mechanically bond within the bicinity of the conduit or box we are running our wiring through. No need to non-mechanically attach anywhere.

Why is it #6? Usually the solar panels wire size determine Array Teks size

for this wiring. What do they say please?  --Dave
