The title is clickbait but they are more reasonable in the copy. From this article:
That’s because most panels are designed to supply power to the grid -- not directly to houses... So systems are tied into the grid, and the vast majority aren’t working this week as PG&E Corp. cuts power to much of Northern California to prevent wildfires. The only way for most solar panels to work during a blackout is pairing them with batteries.
My understanding is grid tied solar would happily power houses during blackouts but,
the grid tie watches the grid and pumps out the same specs (Hz, voltage) as the grid. Reminds me a bit of how our charge controllers need to see battery voltage to know the nominal voltage of the bank
grid ties aren’t allowed to pump power into a dark section of grid to avoid electrocuting worker bees doing their job
a sensor that allowed the house to be taken off a dark grid could allow 120v/60Hz power to still be generated for the home.
