I've bought 2 of the 220W folding Renogy panels off Aliexpress for around $130 each. I've tested them a couple of times and have been thrilled with the numbers. Both times got around 180w-185w per panel. And that's without trying that hard with positioning. Much better real-world numbers than many other panels.

Napkin math, 15 - 20 Amps gets you about 2 miles per hour, which is at 120 v RMS. Lets call that 17 amps x 120 volts = 2,040 Watts

You'll need an AC inverter to convert to that 110 your charger expects, which lets call it 90% efficient, so around 2,300 watts at the panels. Given you probably won't get 200 watts from these real-world, lets use 150.

I'd buy 16 of these (and an inverter to handle that power and convert to AC), that should get you charging your tesla at ~ 2 miles per hour.

This is why solar panels on the roof don't make sense for all but the lightest, most efficient vehicles. The added weight just doesn't get you much.

Youre the best. Thank you for laying it out for me.

Most cars have the inverter on board and the chargers are "dumb". Shouldn't need to go dc->ac->dc and deal with efficiency losses.

I have panels on my roof with net metering (earn credit for the power that I send back to the grid). During the summer I generate more electricity than I use, even when charging a Tesla Y and Cybertruck.

They meant panels won't make sense on the roof of the car

Tested this over the weekend on my Ecoflow Delta 2. Got around 148 to 152w charging speed in central Arizona (temp: 80 to 100F during 5 hours of charging), without optimizing the panel positioning.
