wind~solar hybrid system
 

this is the type of system I would like to have. I know this article is old but it has some good illustrations.

page 4 has a nice illustration of how it all ties into the grid.
Anyone have any personal experience with something like this. I'm trying to find a price range so I can calculate ROI
