You do realize of course that the Lavo fuel cell while amazing is far less efficient than an actual battery. Despite what the picture looks like, it is the size of a large refrigerator and loses over half of the energy input to heat. To top it off they are very expensive. Currently, a bank of lead acid deep cell batteries would be far more efficient, very recyclable, and over their expected useful life, far cheaper. Lots of people are using them for off the grid living right now. You do not need to wait.

When my solar system finishes paying for itself I'll upgrade it with whatever technology is available for whatever part of my system is at its weakest. With my power bill I calculate how much I'm paying per kWh (minus the flat monthly rate), I then calculate how much I saved that month by the # of kWh I consumed from my solar, and that amount is how much I'm paying toward the HELOC I took out to buy the solar. In the months the HELOC minimum payment is less than the savings I pay extra on the HELOC to pay it off sooner. In the months the HELOC is more, I pull what I need from savings to pay the HELOC and put that money back later when my solar saves me more. In 10 to 15 years (depending on the inflation of energy prices, largely from greeny control freaks pushing up natural gas prices) it'll be paid off and I'll use the monthly savings for upgrades.
If the F-150 Lightning is as good as advertised (it's supposed to be as powerful as a 6-cyl F-150), I'll buy a used one 5 or so years from now and use it as my commuter/family chores/church chores truck. I'll keep a gas car for if we go more than a few hundred miles. But at least part of my power for an EV would be free with my solar. I currently average about 3 hours per day when my batteries are fully charged and have unconsumed power I could be utilizing somewhere else. On the weekends and days I work from home (i.e., the car is parked in my garage during daylight hours), those extra solar hours I'm not using could be charging up my truck. I'd worry less about things like the Dims banning fracking (like Biden is already doing to some degree) and limiting our oil and natural gas options if even my truck is powered by solar (at least some of it).
