A HVDC cable from Sahara to America would loose 50% of power, but still would charge your car overnight. As solar install itself is around 50% of it's cost, it's probably cheaper to do so in a dessert than over your house.

HVDC is expensive, solar panels are cheap, so it's usually cheaper to keep the solar panels local even if they're much less efficient than they are elsewhere.

HVDC saves on overnight batteries and is a hedge against weather and other factors.

This is one of the places where hydrogen might actually be viable.
Use a huge excess of solar power to generate hydrogen, transport hydrogen via oceans to ports, store it and convert it back to electricity locally when needed.

Ammonia is probably better. Easier to liquify, and much more dense, even if not as much energy per kg. It's admittedly somewhat toxic, but hydrogen is also somewhat explosive when mixed with air.
