Solar charging on a scale to replenish the battery for driving isn’t practical.
Let’s say you have the 180kwh pack. That’s 180,000 watt hours.
6 100wh panels would cover the entire car and more (and weight about 200lbs). So even in the best conditions it will take 300hrs or assuming at least 12hrs of daylight a day, 25 days to fully charge.
That’s a best case scenario. In reality expect half that efficiency and plan about two months to fully charge.
If you’re using solar on your house and only topping off the battery after a few days then sure. But portable. Not there yet.
