Placard

[GerryB]

I see some residential solars with a placard that shows where the modules are on the roof. Is that a requirement in NEC 2017 or other years?
Maybe 690.31(4)

It's a common way to meet 705.10 which requires a directory, if not explicitly a map. I think the map has also been encouraged by a lot of fire departments who like the idea of being told where the solar panels are.

Yes. "Directory placard".

List all power sources and their disco means.

It's really needed where the INV, ESS (battery) and/or disconnecting means is not adjacent to the MSP.

Pro tip: orient and print placard, so where you apply placard on site is shown at bottom of placard.
ie when you are standing in front of placard on site, the placard shows what is ahead of you.
This makes it much easier to makes heads and tails of site for first responders.
This is a req. in some jurisdictions.

You can peel'n'stick or screw or rivet the directory placard.

About $30, there are services online and a guy I know, pm if needed.
