Solar Electricity became the cheapest electricity in human history last year. In 2008 it would have taken 20,000 sq miles of panels to power the entire usa. That number has come down dramatically as panel efficiency went up. Just to put it in perspective.... coal mining took up 13,000 Sq miles.
It is cheap, but it isn't built yet. It will take some time to get there.

Not if local utilities have anything to say about it.Not even enough to cover our daily use most of the year.

They're fighting solar on homes tooth and nail. Mostly with forcing of EV rates that are higher.

Eventually I expect them to lose. But not for many years.
"Our utility won't let us install more than 5kW."

I'm sure that's 5kW max fed back into the grid. If you feed it direct to something other (like an electric vehicle) I can't see how the utility would know about it, or have a say if it did know.

You need permits to get solar installed (legally anyway). That is how the utility knows the size of system you are getting. So they won't approve the permit for a system over 5kW.

Now it is true I could do 1/2 off-grid and 1/2 grid tied. But then I would need two breaker panels without any interconnection allowed. What circuits go on which panel?

Cost and complexity just became too much and I canceled the install.

I was having Tesla do solar roof tiles, but they are not flexible for weird installs like this would have become.

The US currently has the capability to produce 1.2 terawatts of power. If all of that was running, we could produce 10.5 petawatt/hours of energy per year. That is more than 2.5 times our current consumption. Power generation isn't the issue, it is delivery. And that isn't an issue if home chargers are limited to nighttime charging.

The average power draw over 12 hours of charging at home would be 1,000W. Less than an air conditioner.

The vast majority of people are not going to have fast chargers at home, and even the ones that do aren't going to fast charge everyday because that will reduce their battery life.

No. Well, you need a permit for a system that feeds into your house, but you don't need one for anything not connected to the grid and not permanent on the site (like fold up pieces, on a temporary structure or vehicle), or low voltage.

The utility cannot have say over your panels that only feed into, say, a backup battery.

The fire safety of not blocking egress, having disconnects, and in some places giving them space to attic vent (a dangerous procedure that should be retire) apply, of course.

Interesting discussion but it seems a bit dated as he states at least twice “In 2020”? Locally, I’ve watched coal fired power plants shut down without a sustainable solution to replace that energy. I’ve watched population growth across the states? Recently issues in Texas basically shut down the state where Joe Biden declared a disaster? I live in Colorado where sun shines more than not. I would hope that both State and Federal Governments might increase incentives or add programs that might attract more residents to manage and control their power consumption? But, BIG power companies are in the business to make money so I’m sure that won’t happen. I think when I receive my CT, I’ll have invested in a solar system that will take care of my electrical power requirements with energy to spare for the future. Not sure everybody will be so fortunate to do so but if those that can will, it may help keep the market competitive and the energy rates under control.
