A finishing-stage home build can still hit an unexpected snag. No, it's not the roof, wiring, or inverter; it's the warning labels affixed across conduit, boxes, and battery equipment.
That was the frustration behind one homeowner's question on the r/solar Reddit forum about whether a solar-equipped house could be held up over sticker placement before receiving a certificate of occupancy.
Here's what to know
The issue came up in a Reddit thread where a couple nearing the end of a new-home build asked whether the 2023 National Electrical Code really requires solar warning labels in so many spots, including conduit, junction boxes, and the shed housing the inverter and batteries.
The poster wrote: "My husband is insisting they will fail us if we don't have these stickers? Is it really this ridiculous?"
Most replies said the same thing.
"Yes, they're there for very good reasons," a top-voted commenter wrote. "Anyone that comes to fix an issue needs to know what they're getting into before they open a box."
If the goal is to pass inspection, the labels matter.
"Yes, many, many, many... Electrical inspections have been failed for lack of a sticker," another poster wrote.

More background
There was some skepticism over how much labeling should be required. Some of the pushback centered on how many different entities can influence labeling requirements, such as inspectors, utilities, and fire officials.
Small code details can slow final sign-off, delay move-in timelines, or delay permission to operate when overlooked.

One commenter called it "ridiculous," and said the overload can "eventually lose their meaning when it's so cluttered that no one can tell what's what."
Others said the stickers should not be treated as decoration. In an overnight emergency or after severe weather, they argued, crews need a clear signal that "something nonstandard" is installed, along with instructions for handling it safely.
What can be done?
For people building or upgrading a solar home, the most practical step is to ask installers for a complete labeling plan before final inspection.
It can also help to confirm requirements with the local authority having jurisdiction, since enforcement may vary even when the underlying code language is similar.
