Looks like a decent deal. Can I connect several of these in parallel, to power a 10,000 btu window AC? Or would I need a cheap inverter first?
I mean are there cheaper fixed panels out there, or are they all pricier now, due to importation taxes?
Or grade B panels or Craigslist panels...

Considering that a 10k window AC unit will draw roughly 9.8 amps, you'll need 1200 watts of power. These two panels are rated for a total of 60 watts (if you happened to be at the equator on a mountaintop during the equinox at noon, but we'll ignore that for the moment), so if you were to wire in parallel 8 groups of (6 individual panels wired in series) [6s8p] you would produce 12.9 amps of 110v electricity. However with a solar array that large, you would want to add a mppt solar charge controller a deep cycle battery bank and an inverter. Plus, assuming you're not on a cloudless mountain on the equator, you'll need to add some additional panels to make sure you can actually power your AC unit during the hottest 5-6 hours of the day. An additional 16 individual panels should be sufficient.

So you'd better buy your 32 sets of these panels quick before the Slickdeal effect occurs and they run out of stock!

And please send some pictures of your setup after you've got it all installed!

You can get a mc4 to 8mm adapter and this will charge your cheap Jackery battery.

If anyone is thinking of this seriously, you'll need an inverter to convert the DC from the panels to AC.

Though at that point, you'd be better off getting a whole home system installed with the aid of any rebates that might be available in your area.

Are these panels compatible with any inverter / generator or do you need the Sunjoe inverter generator?

Buying two gets you free shipping. Pretty good deal if you want foldable solar panels from a reputable brand if you buy two which gets you free shipping (total of 120w for $80). With two you can do either 2S or 2P depending on your preference/setup. These Sun Joe panels use standard MC4 connectors. You can match them with pretty much any solar controller/all-in-one so-called "solar generator" with the right adapters.

BTW be careful buying at fleabay from those no-name dealers. Pay attention to the physical size of the panels. A lot of them just can't be true when claiming high wattage with such small sizes. Physics won't lie!

If Edison had won the electricity battle, you wouldn't need an inverter.

Just sayin'...
