BTW Solar is a catch 22 situation. You have more power so you use more power and then need more power...

You need to do some more reading and figuring.

There is no Catch 22 in the use of solar power. A wistful myth.

When people create their own power, they become much more aware of how they use it. Their consumption goes down. The same thing happens when people have to pump their water through a filter, they use less. It creates awareness in people.

I have generator, but using solar panels is about the greatest improvement to my RVing that has ever happened.

I have looked at slide trays to mount on the roof. This could give 3 or 4 across when deployed.

If you really want air conditioning for extended periods you may need to remove the existing unit to add more panels and go with a more efficient mini split air conditioner. Probably need a large lithium battery too.

I run 8 group 24 wet batteries on the tow vehicle, and two more on the fifth wheel. Thats roughly 400 lbs on the truck, which by themselves will run a 1500 watt block heater for about 4.5 hours. After that the batteries still have power for smaller loads, just not the heater. We have 640 watts of solar and run a couple of small room ac units in the fifth, and could probably run one for about 14 hours @ 500 watts just off the batteries. For sustained real life situations, I think I would need to double the solar and batteries to run one set while charging the other and be able to run two ac units. When I last looked, @ 97 outside temp, inside was 78-80 depending on where, with bath and bed closed off, two small ac's and two smaller fans running to circulate the air, using 1060 watts. In an ideal lossless world, I have 9000 watt hrs available with all ten batts. A lot less in real life. But it is all fun stuff.

Mounting the panels above the A/Cs is an option, mine are close to that.

i would think mounting above the roof AC would bring in heights limitations. and maybe make some accessiblity issues with other stuff up there.

Good points and clearance should always be checked before adding anything on the roof. 1" above my A/Cs would place the panels at 12' 6" which leaves plenty of clearance. Access is a minor issue - remove 2 bolts and tilt the panel up or 4 bolts and move it. All of my panels have MC4 connectors so wiring is a non issue.

My panels are about 6" above the roof and just below the A/C's as seen here. In my case the Fantastic Fan is not accessable. https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/28119528.cfm
