None of what you're describing comes anywhere close to meeting the definition of "indefinitely".

If there is no sunlight available, no amount of solar panel "upsizing" is going to help.

You are going to run out of power.

If you want to be pedantic.

Sure if you park for a month in deep heavy forest and never leave, it won't work.

But for non-pedantic potential buyers with more typical use patterns, it's very much viable. Even in heavily shaded sites, if you start with 100% charge, you should be good for several days.
