It takes 3-4 days to fully charge my car 0-100% using a 120v wall plug. That's about 1500W, which can be produced by 3-5 panels depending on their size.
That's the slowest charging method using not a lot of panels. I would also hope you're not planning on regularly driving 200-300 miles to need this much charging.
EV Battery Capacity is measured in Watt Hours, not Watts.
If you had 1500 Watts Hours in an EV Battery... that'd be about 1/10th a charge of the earliest EVs with roughly 10 kWh batteries and less than 1/100th of the CyberTruck's approximately 123 kWh battery pack.
Yes, 3 to 4 smaller consumer grade solar panels ... really more like 8 to 10... can have a cumulative energy production of 1500 Watt Hours...
But Watts are not Watt Hours. And 1500 Watt Hours is an extremely small amount of energy in terms of an EV.
I entirely do not mean to be a dick here, I'm genuinely curious as to what you are actually trying to describe.
