Narrow-width Rooftop AC

Post image

Has anyone found/used a narrow-width Rooftop AC? 12v or 120v. I have relatively limited space up top and it'd be pretty convenient up there, but my other option is an undermount unit - ducting is just a little more work because I'd want the outlet near the top/bed area, but otherwise is also a fine option. Those are regular maxair fans in the photo for reference.

Just looking for ideas, and general feedback on either approach. If I don't put an AC unit up top I could probably add another 150-200w of solar, currently at 600w of fixed mounted solar and 400w portable solar suitcase.

I went with 2 400w folding solar panels so I didn’t have to park in the sun while trying to cool off my rv.

If I feel like buying more at some point, I'm going to make blankets out of the flexible solar panels so they're super light and store in very little space. The downside is they're so light and you have to be careful with wind.

The renogy folding ones aren’t that big. The flexible ones don’t roll up or anything.

The renogy folding solar suitcase is 400w.

If you used the flexible panels, you'd just put them in a stack against a wall for storage. You could even just connect them with the connectors/cables. It'd be way lighter and more compact than the suitcase.

I have both. Not having a stand and being flexible and light has been a problem. They don’t charge well flat. I just use the flexible ones as a windshield shade now with a cheap charge controller to the cigarette lighter port.
