I have another ? regarding solar; we run 2 6V 250 AH AGM batteries.
Will the 100w be sufficient or should we be looking at a larger system?
I do understand the system should be sized for your power consumption and the size of your battery (s)...however our usage is minimal but all the 100W system I have researched say they are good for charging 1 battery?
Does this mean a 100W panel will be totally insufficient for charging dual batteries?

Depends on your battery usage. 200w would be the more common route I'd think because 100w of solar isn't even enough to run a 12v fridge (although I assume you have a propane fridge?). If you don't use a 12v fridge and don't use much electronics then 100w might be enough, but solar is so cheap now so if I were you I'd go as much as you can. As for the "100w per battery" that's not really a relevant measurement. No, 100w will not be insufficient for charging your 2 6v batteries.
