I'm thinking you have effectively 190ah.

Shading will drastically harm your output on series-connected panels unless they are well-equipped with bypass diodes. I guess you mean you'll just be using those 2 panels by themselves.

Usable charge 190AH, yes. (It's AH, not Amps).

Don't know where and how 2 portable panels came from, in this topic, (and what power). Portable panel off the shelve is 100W, split in 2*50 squares that fold onto each other like a suitcase. Buying 2 of them will give you mere 200W total and will cost not much less than 600W permanent install. Will be a bit of pain to set up and break up every time, not sure what to do with it when you're away from the camp, and this is financially inefficient, compared to permanent install. You could buy your own panels as big as you like, even 250W, and make your own portable array, but panels bigger than 120-140W are heavy and bulky, a nightmare to carry around and store inside.

If you camp in the woods most of the time, portable could be the only choice, otherwise - forget about it. As an addition to permanent 600W, maybe. One 100W suitcase, for those occasions. Just one - you might not be able to use even one, depending on distance to the closest sunny spot. I would make that permanent more than 600W if possible.
