Solar charging while car camping

[joecool99]

Say you are out in the wild for a week - plenty of sun - is there any solution, rollable solar panel mat that will allow for even minor charging?

There is this solar panel for outdoor:

But how to hook it up to charge?

Maybe a Jackery with solar, but if you compare the jackery’s Battery capacity with the Taycan you will see that a car battery has an enormous capacity compared. So it might take a very very long time to charge on portable solar panels.

There is a minimum threshold of 1.4kW needed to start charging. So in theory it’s possible but you’d need a lot of fold out panels. Plus you’d need an EVSE that would work in that scenario - ie understand what is availabile from the panels and control the car charge rate appropriately.
It’s complex and really there would have to be a dedicated product designed to do it. Don’t think there is one currently. Note too, at 1.4kw it would take a couple of weeks to charge a Taycan.

Not practical.
Even using the supplied charger with the supplied domestic plug is emergency only IME, it takes about 48 hours to charge the car at 2.1 kW (whilst using 2.6 kW since the car seems to use around 0.5 kW to drive the internal charging infrastructure)

at 1.4kw / h it shouldn't take a couple of weeks but something like 3days.

No sun at night….
