Solar charger questions

I have recently bought a class c motor home and am spending the winter on the Gulf of Mexico in Alabama. I live in NYC and had been debating myself as to whether or not I should store the rig here or upstate NY. I can't imagine I would use it for more than a week or two. Anyway today was the first hot day I've experienced here and for me it was brutal 72 degrees and 100% humidity. That has made up my mind and I will drive the rig back to NY. It will be stored 120 miles from me and about $75 each trip out. tolls and gas.
What I'd like to know is will solar chargers on the engine and house batteries keep the batteries charged enough so I need not visit the rig except for bi monthly? If so is there any recommended setup. Thanks

A couple hundred watts should do nicely if you can keep the snow off the panels. A controller with temperature compensation would be a plus.

Assuming the batteries are fully charged, it only takes a very small trickle charge to maintain the battery at full capacity. Like 5 watts, or about 0.5 amp is plenty. It does not take much at all. If you have access to electricity at the storage, a battery maintainer, also called a float charger, will do the same to keep the battery up at full charge.

Hey Easy, We have 80 watts of solar on 4-6 volt house batteries with a regulator. The batteries were always charged no matter how long it sat. I would check the water in the batteries monthly. It worked great! If the starting battery was low I would use the battery boost switch.Good luck!

Thanks for the replies, I think a trickle charger would do the trick, no electric at the storage place. I only have one starting battery and one house battery and am/will be plugged in all the time except when driving to a destination and that is usually hundreds or thousands of miles. In reality all I want to do is be able to start the rig.
