The Best Solar Battery Powered Water Heaters

We have wanted to work at going solar for a long time and finally we just decided to do if just a little at time.  Heating the water seemed to be the easiest thing to do so we start looking into solar Battery Powered Water Heaters. There is quite a bit of information out there on how to set up the solar panels and the storage batteries. Also the regulators and controls didn't look like that big of a deal.  I was really impressed that it was so simple to use really and you could just switch over to regular electricity if there wasn't enough solar energy stored.
