Grid tied solar panel mount

Stowage is the issue with my panel. I've looked into 100w units and see the sizing is better to stow. Maybe two of this would suit me better.

I mentioned Flexible mainly due to stowing away and the price is coming down to being comparable to hard panels. Would I mount them, or mount a hard panel, probably not. Don't like the idea of parking in the sun.

I'll lean on Offgrid to voice costs vs. duration of hard side to flexible. Right now I can buy either for around a dollar a watt, puts them close to par for cost.

For me, if mounted, I would double (maybe triple) my wattage so I still don't have to park directly in the sun.

The holy grail of boondockers: off grid a/c

I want to install a high efficiency mini split condernser where the batteries are now and the evaporator would go above the head end of the bed in the 179. That will not only clear the roof for solar but will also reduce the electrical load of the a/c by nearly 50%, RV roof airs are not shall we say state of the art units. Not to mention the noise that will go away, the minisplits are whisper quiet. 

There is no way to carry enough capacity of lead acid batteries in an rPod, you are absolutely correct on that point. So, I would need to install a lithium pack. Probably I'll use a salvage Tesla auto battery. They are 24V and 5kWh and are pretty reasonable on eBay. They only weight about 50 lbs so I would save weight over the dual lead acid batteries I have now and give about 4x the useful capacity. 

My calcs suggest that that and a 1kW solar array should get me through about 12 hours of nighttime (not daytime) a/c use, we don't usually use the a/c in the daytime anyway because we're outside most of the time. I'll need a 24Vdc to 120Vac inverter for the a/c and a 24V to 12V dc dc converter to run the existing 12V trailer loads. 

Anyway, that's my basic plan, we'll see how it all works out. 

For me, I either camp on the beach here on the OBX where it is hot, humid, and (generally) sunny or in the mountains where its cool and shady. I don't need the a/c in the mountains and have direct sun on the beach. The National Seashore does not allow generators at night which is when I want the a/c, and only has a few hookups which are in high demand of course. In the mountains even a mostly shaded 1kw solar array should provide plenty of energy.  

That being said, I would still want to have a fossil fuel backup source no matter what. I'd like to try alternator charging of the 24V Tesla battery via dc/dc step up converters, that should solve the problem of not getting enough charging current from an idling engine in the TV. If I have a cloudy day at the beach I can run the TV in the late afternoon to top off the battery. 

My biggest concern about my plan is that the minisplit might not hold up to the vibration from travelling, we'll have to see.
