DIY solar panel for Mighty Mule gate opener

I am looking for input, hopefully from someone with some electronics knowledge/expertise; I have very little.

I would like to hook a solar panel up to the battery on my mighty mule gate opener, rather than spend all the beans on the "mighty mule" panel. The output on my panel on a sunny day at noon time in NE CT two weeks ago was approximately 20V DC, which is right where the branded panel is purported to be.

My question is whether there are electronics built into their panel that prevent overloading or draining of the battery; or rather, should I try to build a simple circuit to do this and if so is there someone willing to help me design such a thing? I can assemble and solder this I am sure, just don't know how to design what I might need.

I can provide more specific information to anyone interested in helping.
