You need a fair bit of solar. Doable with foldable panels but you need multiple. Haven't done the math on modern ones, probably looks reasonable-ish now.
Starlink Mini averages around 20W during operation. I have one mounted on my truck, and use a foldable 200W panel when in remote areas (to also charge the aux battery and power other electronics). When folded it's about the size of a briefcase/small backpack. A smaller panel would certainly be enough for just the Mini.

A quick amazon search yields this 40W solar panel that is almost exactly equal to an iPad mini when folded: https://www.amazon.com/2026Upgrade-Efficiency-Waterproof-Lig...
Prices vary from just $40 to $80. It's certainly possible.

The mini 1 is rated for 40W, so not too much solar. I'm guessing because the Mini 2 has a battery on board it's likely less power than 40W.
A 100W foldable would likely give you enough power.
