That's some pretty cool stuff. Have you guys collected any data on energy cost savings, or when your break even point would be for something like that? Just curious.
I'd cover my roof in solar panels, and throw a wind turbine in my backyard if it generates enough energy to cover costs, and possible sell some back to the electric companies.
The company I work for continues to invest resources into the solar industry, and although the technologies keep advancing, there's just not that much real solar business to be had out there yet. It's definitely coming, but who knows when...
