I'm not at all anti-solar, just using an EV for what an ICE vehicle is better equiped to do is bizarre.
Yes, it is better at everything, especially tasks around farms/countryside. Sure, keep charging the EV slowly when there are clear skies, but even fully charged it will not be the best tool for any job.
It's easy to understand why when you realize that any EV trying to compete in a given ICE category weighs considerably more than the ICE average. And that's after the brilliant engineering done to reduce weight wherever possible. That's the tax for trying to compete with current battery tech, nothing against it.
But these over-engineered vehicles give up maintainability and strength just to keep up. Cast aluminum parts which are hard to diy in case of breaking. You are not welding the frame of your cyber truck back together for instance, if it snaps - the entire thing is cast. It has to be, to compete. You can throw the invincible hilux down a waterfall amd drive away.
EVs are the premier league of compromise, and the tech is barely competative with gov assistance now. It's a dying class of anti-free market manufacturing porn.
The best thing a Nissan Leaf can become for a self-sov homestead is the backup battery for the solar setup. Driving it would be a waste of productive power.
