Off the grid means 2x+ the amount of solar compared to being NZE (Net Zero Energy). Most homes do not have the roof area to do that.
Solar efficiency continues to improve. So you won't need as much roof space for 2x the output. Also, you can use a ground mounted system.
The 2x+ requirement has nothing to do with panel efficiency. Panels could be 100% efficient and you would still need more panels to be off-the-grid than being a net zero home. It has to do with the reality of fewer sunlight hours in winter than in summer, and with more overcast days in the winter. Even with a solar tracking system that aligns the panels to perfectly face the Sun, you have, maybe, 9 hours of sunlight on a sunny winter day, and 14 hours on a sunny summer day. Assume on a cloudy day the in 9 cloudy hours a solar panel system generates 6 hours of power (1/3rd lost due to clouds blocking solar energy) and you end up at 6/14, or about 40% as effective an electricity producer in winter as in summer.
Off-the-grid means surviving during the lowest production time in winter. The system is oversized in the summer, and the excess energy has nowhere to go, so it is wasted unless the home is grid-tied. Utilities don't pay you anything for power you create and send into their grid. They provide rollover credits that can be applied when a home uses more electricity than it generates. Such credits are use-it-or-lose-it, which means if you don't use they expire (typically after a month's credits have aged one year).

The square feet you need for a given output has everything to do with panel efficiency. As I was saying, many will have plenty of room on the roof. Others can use ground-mounted systems.
There are plenty of people today who have large houses with off grid systems combining solar and battery storage. As prices go down and efficiency improves, millions more will be able to do this as well.

Panel efficiency is not related to area. A 100% efficient panel is not more efficient if you have two.
Sunlight hours are the driving factor. You cannot change the fact that there are fewer sunlight hours in the winter than in the summer. No matter what you do, a home needs more panels to survive during the winter than in the summer.
How would you take a 50 story, 500 unit condo tower in Manhattan and take it off the grid? Even if you converted the facade to solar panels, there are windows. And south facing condos are more exposed to the sun than north facing condos. Then you have to take into account adjacent buildings blocking direct sunlight. That all adds up to need a lot more panels to compensate for the reality of sunlight hours, and local solar availability conditions (hills, buildings).
You should be aware that the #1 rule to reducing overall energy use is to address end uses first. That means converting lighting to LED, high efficiency heating systems (such as a condensing furnace), turning lights and other equipment OFF when not used, and tracking down parasitic loads. Parasitic loads are energy drawing equipment that sucks power even when it is off; they are also referred to as vampire loads and phantom loads -- power suckers. Power bricks (plug transformers on computers and other devices ), big screen TVs, cordless power tool chargers, and similar, are notorious for using power when they are "off". This is a fact. I know this because I helped a major utility with an incentive program to encourage home owners to upgrades windows, heating systems, water heaters, lighting, and major appliances (Energy Star). The expected energy saving did not materialize. Spot metering plugs in homes revealed that the problem was people installing too many other pieces of equipment that used energy even when off.

it's 100% clear that Kamala is being given a tryout for the 2024 nomination. Biden knows he might not make it too much longer - he wants to give her a running start for 2024 if she is needed.
Expect her to do a lot of potus-type activities to see how she does and to give her more experience.
Biden isn’t capable, he's downright feeble. Even Obama didn’t want Joe in charge of anything. "Don't underestimate Joe's ability to f--- things up."

As I said, the square feet you need for a given output has everything to do with panel efficiency. For the same output, a hypothetical 100% efficient panel requires half the area as two 50% efficient panels. My previous statement is absolutely correct.

There is no single driving factor. There are many.
Yes, you need more panels in the winter than the summer. So you use some combination of more panels, more efficient panels, tracking panels, more batteries, more insulation for the home, more efficient appliances, etc. There is an infinite number of engineering solutions. You just try to pick the one that is most cost effective for a given situation.

Most of Manhattan would stay on the grid, powered by nuclear, solar, and wind.

I am aware of all that stuff.

Yes, everyone should do what they can to cut energy usage. That's very important.

Gary and friends Bad, Igy, Biff are suffering from some serious cognitive dissonance. They are still shell shocked about trump's epic loss. It's not even comparable to a bucket of ice water to the face, it's more like they suddenly ran out of oxygen and are in agony knowing it won't come back. Their tears are our champagne.
So it looks like Convanka will not challenge lil Marco in the next election. She seriously thought she could be POTUS someday.
The tzees are relentless

But but but March 4th!
And then but but but Easter!
And then but but but May Day!
And then but but but the Fourth of July!
In 2016 Donald Trump got the votes he needed, in the states he needed, to win fair and square in the Electoral College. In 2020 Joseph Biden got the votes he needed, in the states he needed, to win fair and square in the Electoral College. An adult knows that *both* of those statements are true and MOVES FORWARD.

I don't know about most authentically Republican, but Perry's response is the most authentically Texan.
Texas pays dearly for the right to pretend that they are independent.
