For some reason in the USA there is only a single state that has approved that (Utah).

It conflicts with some of the NEC (national electric code) requirements. That all needs to get sorted out.

  The NEC is also in conflict with homeowners performing simple electrical work, such as replacing switches and outlets.

    It is. But in this case the conflict is more fundamental - the NEC has no provision for a circuit that has multiple electrical supplies.

      If you have a circuit rated for 15 amps, and plug in 12 amps of solar, then the breaker won't trip until the circuit load exceeds 27 amps, which seems bad.

        Hmm, if you have an appliance (like a clothes dryer) with a dedicated circuit, it seems like you could solve this by connecting there. If you have the balcony solar device plug into the wall and the appliance plug into the balcony solar device, then you can easily put an additional circuit breaker where it's needed.

    Not all homeowners are built for even these simple tasks. I watched someone try to replace a receptacle live, all while wondering why it was arcing and tripping the breaker repeatedly.

      My solution would be using trade schools to run a homeowner electrician's program, teaching folks basic safety, measurement, and mechanics of what they would need do the work safely. A program like this shouldn't take more than a weekend to cover all the issues including a Hands-On lab. A second weekend could be added for ground mounted solar setups. I'd be willing to pay a couple hundred bucks get such a ticket.

      Uhhh...how long exactly did you "watch" this?

        Lol I can't recall, but I think eventually they gave up trying to restore power until it was finished. Perhaps they found a flashlight.

    Did something change? Iirc you can do that sort of job yourself.
