It can also be hazardous for electricians or DIY home repairs if they don’t know about it.
Oh, you think you’re safe because you turned the house’s power off at the main breaker? Forgot about the solar panels backfeeding into the panel – all the circuits are still live!
(Or, even more fun, only half the breakers in the panel are still live, since the solar panels are only feeding into one of the two phases. So maybe you test to make sure the power is off by turning on the lights, and the lights don’t turn on so you think you’re safe. But the power outlets you’re about to work on are on a different circuit, one that’s on the same phase as the solar, so they’re still live. Fun stuff!)
All that’s to say… You should definitely still do home solar if you can. But document it well, and establish ways to disconnect power to ensure safety!
