However, with an MPPT controller, it almost doesn't matter. Stack up the number of watts you need, and adjust the output to the batteries/load as needed.

Actually, most Solar Panels are rated at about 18 volts... My setup is a Goal Zero 100 watt, 100 watts/18 volts = 5.56 Amps(In Direct Sunlight). I have dual golf cart 6v batteries with 225 Amps total. With 80% usage(180 amps), it would take 32 hours of Direct Sunlight to charge the batteries... With my setup, will theoretically last about 7 -10 days between Battery & Solar.

The guys are right about 6 volt GC battery size. They are taller than 12 volt, and about 10 pounds heavier each. Mine are 62 pounds, each.
I have 2 Trojan T-105 batteries in my toy hauler. They have been kept charged since May only with the 150 watt rooftop panel. The propane detector is on full time. I just checked battery cell water levels and Ph tested, and everything is still tip top. The solar converter is a Steca Solarix PRS 1515, 15 amp unit. Seems to keep it well charged without overcharging or overheating the batteries. The batteries are also inside of the nose of the cab, inside a vented battery box.

I came across this the other day and thought it a good primer:
I have been camping with these dual 6's for 3+ years now and have been very happy=> https://www.samsclub.com/sams/duracell-golf-car-battery-group-size-egc2/prod3590220.ip sailor323, thank for the link. Panels are almost at my $1/watt purchase point. I want to start with 200 watt and see how it goes. I want to build my own portable system. I really like my Yamaha 2400, but I'm getting tired of lugging it around. fred |

As I said earlier, consider using the equivalent of Trojan 145s. They provide 265 amp hours of storage. I would think that 100 watts of solar to be the minimum for most users. We have 280 watts mounted on the roof--very satisfied. You should understand that solar panels, regardless of wattage are virtually worthless in the shade. I got panels for the pod and the boat from very helpful folks. I don't think they sell flex panels, though

Ty for the replies, This is way out of my area of expertise, so if you would, tell me which batteries and solar panels to get. I would love to mount flex panels on my roof, if you agree this is best way to go.
thanks in advance!

+1 for the dual 6V batteries. It is not just a matter of space, but of weight. You can get a lot of use out of dual 6V batteries. I agree also that a 45 watt panel is not adequate. That is only about 3.75 Amperes under the best circumstances. That is barely a trickle charge when you are considering batteries rated at 215 Ah or higher.
