You'll need about 5 football fields covered with solar cells and probably $50 million, plus a staff of engineers and technicians to make that dream come true.
It's a nice dream.
Actually, with current solar panel technology she could get'r done for about $60K, a few hippies and her back yard, but that will charge one vehicle, during the day.
Better to use the solar to run the house A/C and use coal to charge the car at night.
"with current solar panel technology she could get'r done for about $60K"
She'll need approximately 100 square meters of uninterrupted sunshine on a set of collectors to fill up an emasculated vehicle on electricity in a day. That'll cost a bit more than $60k, I think. If she doesn't mind waiting a few days to fill'er up, she might be able to use a smaller array.
