Terminating compound required for all copper connections?

[tortuga]

In parts of my area there is a utility spec we have to follow for PV systems in a large part of the state, since the utility indirectly gives a nice rebate for the installation thru this 3rd party the 3rd party can require this for the rebate.
Its pretty boiler plate but there is a part that requires all terminations to be de-oxed:

2.3.11 All electrical terminations shall be torqued to specification, secured, and strain-relieved
as appropriate. Wire ends shall be coated with terminating compound prior to
termination to prevent loosening of the connection over time.

Now this unlike any specs I have ever seen and I mean military, municipal etc. ( have not worked for NASA yet so exclude them).
Do any of you also have specs like this? Is this standard in the PV industry?
What I typically see is this:

Aluminum or Copper Clad Aluminum wire ends shall be coated with terminating compound prior to termination to prevent loosening of the connection over time.

Thanks for your feedback

Doex can be beneficial, but I dont think it "prevents loosening"

Do you typically use de-ox on all connections of a PV system?

Burndy and T&B make copper only termination compounds. Penetrox E and Kopper Shield. Great products, they are basically colloidal copper and oil. Messy and gets home before you do. I used on pipe threads, and electrical terminations, virtually elimated overheating

Thats interesting thanks, so do you have to apply that to all solar connections up in WA?
We typically carry this ilsco product:

Probably because the utility uses aluminum 99% of the time, so it would be a spec they are used to.

This is not a standard PV industry spec.

Yeah I did a little research on it and apparently the issue was installs in "marine environments" what they call 1/2 mile from the coast line.

Depends on the area. If the system is on the coast for instance copper will corrode in a saltwater environment and protection is worth the extra effort.
