May I suggest a book and web site for your enlightenment? The Book.

I learned a ton from them.

Another is that a single 100 watt panel is probably not enough to keep a 70-100 Amp Hour battery (array, in your case, with two 6 volt batteries) charged up, given that that 100 watts is the maximum possible at noon, in the summer, on a clear, cloudless day, and then only if the panel is perfectly oriented at the sun. You don't specify the amp-hour rating of your battery, but I suspect it is probably greater than 100 amp hours.
Check out the web site. Buy the guy's book. They will explain everything in simple terms.
