The surface area of a car usable for solar panels is about 3 square meters. At the absolute best, when the stars align just right, you're going to get about 1 kW of power out of these panels.

In other words, barely enough to offset the auxiliary systems in the car (cooling pumps, lights, computers, etc.)

For me it likely won't matter 98% of the time. I charge at home and already cap out my existing circuit and it's plenty fast for me (around 10% of range per hour).

For those not with an overnihht charging parking spot I can see the appeal though.

I'll take the 30 seconds of plugging my car in when I get home than the 20 minute detour to the petrol station. Especially because my electric at nighttime is so cheap. But you do you.
