True 'dat! :-) To my surprise, our power company has a free program where you can have someone come out and evaluate and talk about grid-tie systems and such for your home. Our neighbor has a grid-tie system with about 30 PV panels (old though, probably 8+ years). He "makes" about $75 a month from them.
I wouldn't really be interested in a grid-tie system. I'd rather wire up separate solar circuits in the home and slowly switch over, or (more realistically) run a hybrid system with both power options.
Well, if you have a battery system that runs the entire house, it can be charged either from the grid or the alternate energy methods. Obviously, getting started with one of those systems is a little pricey, but in the long run, you have the added security of being able to charge your house battery when the grid goes down. And, you don't have to add the alternate energy methods immediately.
