The US is a patchwork, but it is legal in some places, including Utah!

Bills are popping up in state legislatures across the United States to legalize plug-in solar. I wrote about a bill that was up for consideration here in Washington state earlier this year: https://www.brethorsting.com/blog/2026/01/washington-should-...

Unfortunately, the bill didn't make it over the finish line during the 2026 session. The Washington legislature only met for two months this year: https://www.brethorsting.com/blog/2026/01/how-the-washington...

I'm in Seattle, where we enjoy some of the cheapest electricity costs in the country thanks to abundant hydroelectric generation and a public, city-owned utility, but back-to-back 10% rate hikes were just announced for 2027 and 2028, and I hope that spurs our state legislature to take balcony solar more seriously.

The main risk factor is people trying to pump too much juice into a wall socket rated for a lesser current. Plus the connector needs to be male - shock risk. The combination of live and male is not generally something you see in households and people may not register that it’s something outside of normal household risk profile.

That plus bit of risk of things being energised that say a lineman thought would be out. This can be mitigated by using systems that only feed in when they sense it’s connected to the grid

U.K. wiring is obviously different

Seemed to cover a fair amount of the issues (or non issues)

Is plug-in solar explicitly illegal in most states?
