solar panels

[Eric27]

I'm looking into buying a 40 w portable solar panel. will this be enough?? Any suggestions?

Thanks.

Enough for what? To keep your chassis battery topped off? Yeah, it'll work for that, but not for much else. It's only capable of 3.33Amp and that's with full sunshine.

Enough is a subjective thing. What is enough for me might be way over done for you and insufficient for some others. Personally for battey charging/maintaining when in storage I would start with a hundred watts and a decent controller. If you like to boon dock, then start with 200 watts and go up from there depending on your power consumption.

You didn't say what kind of rv you have, and what you want to achieve, so no answers can be given... Because you are posting in Class A forum so I assume you have a class A DP and you want to have a decent solar system on it... Here you go - I would suggest to put up 2 x 145w up there, this way you don't need to redo it down the road. Make sure use thick wires (6 or 8 gauge) with a 40A (minimum 20A) MPPT controller. This setup will provide sufficient power for your boondocking in most conditions.
