Solar water heating is probably the most cost-effective solar you can get, since it's simple and robust (don't know how long it will last with hard ground water, though... probably need to install some filters).

Do you use an overhead tank? That can help lower your pumping costs, I believe.

The "Do The Math" blog has some interesting data on saving electricity...
