At what cost?
Well, here's a bit of info:

On Grid Calculator at the Alternative Energy Store

From that, if we assume $.12/KWH in CA, the guys $90/month electric usage is ~ 750KW. And that site says you need ~ 6KW of panels to provide that. ~ $25,000 for the panels on that site, plus inverter, installation, etc. Over $4/watt. IIRC, Nords cut that almost in half, but that included a lot of scrounging and sweat equity.

It takes over 9KW of panels for that power in the Chicago area. Even at the promises of $1/watt solar panels 'real soon now', it's not exactly a no-brainer.

These guys always ignore the fact that a solar panel takes a lot of energy to manufacture. It takes about 2 years of full solar production to offset the energy to manufacture it. So for two years, these guys are still burning fossils fuel. And since solar requires so much energy to produce, I imagine the prices will be rising along with fuel costs.
