Recommendations regarding Solar Power
We are new to RVing and considering roof-mount Solar system both to keep the batteries topped off but also to run the A/C or uWave. I'm thinking about a 200 Watt system. I am concerned about where...

smkettner - 2700 W of solar panels should cost less than $2K. You could conceiviably put 14 x 270 W panels on your roof if you didn't worry about a/c and other protruberance. You could probably get 10 without much trouble. We have 1420 W and could put on another 700 if we really worked at it. The 15,000 BTU takes about 2 kW once one realizes the losses through controller, inverter etc. Solar goes through controller to 9.6 kW-hrs of LFP and then through 4.0 PSW inverter. There are definite power losses at each stage. You can do it if you choose. 10 panels would weigh around 400 pounds.
We run off solar/batteries for a couple of hours to get temperatures down to comfortable but it does drain around 1 kW from the batteries in full solar insolation so we have never run more than 4 hours straight to about 55% DOD (LFP). Once it is comfortable, we use the 12V fans.
We are "Goldilockers", "Not to hot and not to cold, just right!" Go up in elevation or north when hot, reverse when cold. But sometimes that just does not work.
But then again with regards to Goldilocks "...Something very strange about the Three Bears, 'how could the porridge be too hot, too cold, and just right if it was poured at the same time?" from "The Fourth Bear" by Jasper Fforde.
