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.
When you feed into the grid, your power has to match the frequency and phase of what on the grid.
If the grid is down, your solar system has nothing to match to and will not send power into the grid.
Grid tie inverters won't deliver power unless they can detect and sync to the grid. If the grid stops working (power outage) and there's no grid AC to sync with, then no power is delivered. It shuts off for safety.
