Yes the home solar array charging the home battery pack which can both power the home and charge the vehicle.

Using a Battery-Backed Solar System
With a battery-backed system, it’s entirely possible to charge your electric vehicle soley from the sun’s rays. This is because during the day your home will use solar energy and any excess will feed into your battery’s energy supply. Long after the sun goes down, you’ll still be enjoying the sun’s ability to provide energy for your home. Now, keep in mind that to truly be “off-grid” and avoid using any energy from your local utility it is likely that you’ll need a sizable solar array and a meaty battery system.

Not to mention the elephant in the room with hydrogen is that it is only economical when its sourced from natural gas.
Again, Your "Hydrogen" answer is only viable when linked to Natural gas.

Charge at night....use back and forth to work or shopping....whatever....400 + kms lasts me two weeks.Unless you want to use your vehicle during the day.
I have a Tesla Model 3 Reservation, Probably won't get it till the end of next year. The first model 3 destined for consumers only rolled off the production line on Friday, and there are about 400,000 reservations in front of me.
The mining of oil/gas and minerals is required to create anything for modern human so there is also that on going affect.Of course the other issue is left over product, with batteries there is still a waste of resources, in the manufacture and when it has finished its usefull life. ( I know they recycle, but that isn't 100% efficient either).
The battery storage can do the night. Here is the link to the article I referred to. There is some math under the map half way down the page so the battery capacity would obviuosly be relevant.Unless you want to use your vehicle during the day.
Nice try, I don't need any more positive reinforcement than the facts.Ah, now I understand where you are coming from, insufficient positive reinforcement.
Base model starts at $35,000 USD.How much are they ?
The electrolysis route has been used commercially in the past, including not far from where I'm sitting right now, but the overwhelming majority of current production is based on natural gas certainly as that's a far cheaper way of doing it.Research it, all commercially viable hydrogen production uses natural gas as a feed stock.
Base model starts at $35,000 USD.
Final price will depend on the exchange rate an the options I select. I will be doing the autopilot upgrade and the larger battery, so I am guessing it will be somewhere between $50k and $65k.

The problem with the electrolysis approach is that that you're starting with a relatively high cost input (electricity) and then losing part of that in the production of hydrogen. In contrast natural gas is a far cheaper feedstock.
Tesla have said their production costs for the batteries is about $125 per KWh, so for a 70Kwh hour battery (which is average size for a tesla vehicle) they battery cost would be under $9000 USD.I'm also shocked, from what I've read, that isn't much more than the cost of the batteries.
Hydrogen isn't a "clean fuel" it is just a way of storing energy, you still require an energy source, just like you do for charging a battery.We were producing hydrogen from electrolysis, at Muja, when I was an apprentice and that was a long time ago.
Like I said earlier, it will only become viable, when there is a major swing toward renewables.
They are using natural gas currently, but when that is depleted which in real terms wont take long, a man made replacement fuel will be required.
Hydrogen IMO is the only clean fuel, other than nuclear, that I can see on the horizon.
Batteries just seem to be bogged down, with chemical reaction and the associated mass required to store it.
If they can better develop the battery/capacitor hybrid technology, where the rapid charge of the capacitor and the energy density of a battery can be mated, they may have something.
But I still feel the versatility and sustainability, of hydrogen, will win the day.

Getting hydrogen from electricity doesn't solve any problems because it is still a very inefficient use of that electricity.
For example, a hydrogen car is still an electric car, it's just that rather than get the electricity from a battery, it has a tank of flammable gas, which it pumps through a fuel cell, to create a current that runs the electric motor that powers the car.
