I haven't, but before my SWMBO nixed my plan, I was going to install panels and a grid-tie in inverter. You can find panels really cheap if you search. You can find them cheap enough that it's totally not worth the time to make your own (IMO). With the tax credit and PG&E credit, ability to sell back to the grid and of course the statement, now is a sweet time!!! I'm bummed I wasn't able to, but I hope you figure out a way to go solar.
