Solar Panel Charger Circuit

I want to make a 12 Volt Solar Battery Regulator. Any help? Any circuit diagrams?
My Solar Battery is getting over-charged by a solar panel because there is no regulator between the panel & battery to monitor the battery energy. I once built a battery charger using info I got from the D.I.Y.com site but this time, the site does not have anything to do with the 12V Battery Regulator. I can make one given a circuit diagram. Thanks
Here is a site with lots of them.

I built an automatic solar array tilting device so my array would follow the sun. Was fun for a while but used more power then it was worth. Same thing for make your own controllers and inverters. It is always fun to build some things but others I found it is just better and faster to just buy one for about 40 bucks or so…
