So, it is not a lot of charging but certainly better than nothing.
Thanks for the insights. You're right, one 100W is better than nothing. :)The new panel arrived today so I'll get it hooked up and see how everything works. We're heading out on a 6 day dry camping trip in a couple of weeks. If all goes well I may add another 100W to replace the 2nd panel.
