Matt and Kelly Grocoff are some of our very first wattvision beta users. Check out this awesome net zero house they've been working on for the last several years -- it now gives back as much power as it consumes from the grid, so it's a "net zero" house. They've documented their work at Greenovation.TV, and if you jump to about 2:00 in the video below, you can see their wattvision setup!
