Many States in the US allow this and it's old hat in Europe. Imagine hanging solar panels off your balcony plugged into the outside plug reducing your power bills. Maybe preventing Ontario needing to buy power from the States.

Honestly, I don't know how I feel about solar backfeeding into the grid. There's a lot of safety regulations to get right, and I wonder how it works in a mains power outage? Are all the lines partially electrified with everyone's solar?
What people can do right now, is install solar with a battery, and instead of making the extra energy the power company's problem, you just draw less power from the wall instead.
With a battery alone you can also take advantage of time-of-use billing if you charge it up at night when there's excess grid capacity.
