Nah you're the retard - our extended family has residential solar and found out the hard way during an extended 5-7 day power outage.

So Nope, incorrect. Most US residential solar power set ups are Grid-tiered systems that automatically shut down in an outage.
You're meaning an 'Off grid system' that are much more expensive because they have to utilize solar batteries, for storage and use at night and during low sun/ solar-light hours.

'Solar batteries are not cheap. A basic battery setup will cost anywhere from $21,000 to $46,000+. This will provide enough storage to power small, lightly used loads during an outage (for example, a well pump, 2 freezers, and (4) 13W light bulbs). A more advanced system that has the potential for whole-home backup will cost over $85,000.
That is why off grid systems typically predominate in remote/ lone locations.

EDIT: Lol, at your downvote. what an idiot. Typical numpty thinks all things are equal regardless of context. - You are conflating two entirely different systems of solar. Overwhelming solar use is 'grid tiered' and do not require batteries but are also shut down with power mains outage, the 'off grid' systems are vastly more expensive and enable complete separation - by regulation you either require one or the other, you can not by law have an 'off grid' system without batteries and still connect to the mains during normal/ day night usage .

Yea, just not in a city or suburban residential area, and then if you do meet all the 'regulations' they will charge you for the pleasure.
