RV solar systems

Minimum solar one watt per battery amp. I love my solar set up.

Need about 100w for storage. 200 to 400+ watts for recharging while in use.

Our solar system has worked great when dry camping. We have two 6 volt AGM batteries providing 220 amp hours of power. I keep them charged with a 150 watt solar panel on top of the trailer and a 100 watt portable panel. The portable panel is easily moved around to follow the sunlight when we are camping in shady conditions in the forest. I recommend to consider a portable panel as part of your solar configuration.

I also have 2 6v and have a 100 watt on roof and a 100w poartable. Works, great!

Hi Stan,

Follow this link for my thoughts on solar:

200 watts (minimum) flat mounted will work fine to keep 2 6v's charged up while you are away, and will definitely extend your dry camping time with moderate use of lights and other electronics. This is assuming you can park in an area that gets a good amount of peak sun hours. We started out with a 200w system and were very happy with the results. It didn't take long to get the solar bug and increase the system though...
Good luck and have fun with it.

I agreed with the 200 watts for boon docking. I have 200 watts feeding a 230 ah battery bank and never run out of power.

Read pianotuna's write up. Do an energy audit to determine battery bank size. Unless you always camp in full sun and never have cloudy days I suggest 120 to 140 watts of solar per 100Ah of battery. While more work a combination of tilted and portable usually works best in the East and during winter.

I'm running two fixed 150w Samlex panesl for a total 300w with a 30a Samlex controller and I have no problem keeping the two 6v batteries up while on extended boondock trips. Best example is camping at the Mojave Desert in November for a week. Temps went down to the mid 20's each night. We kept the coach at 60 degrees with heater on at night. Each day the sun was out and charged everything back up just fine. This whole trip there was ample sunshine. It seems to charge fine with fog too. Surely not as much charge as sunshine but it's not "dead in the water" on a foggy day. I'm a big fan of a "fixed set up" for solar. I never have to think about it...........it just works.
