Hi,
These are an interesting development: the cost ~$900 each, and they have built in inverters, so they can be easily integrated into the AC wiring. They are Akeena Andalay panels rated at 175 watts per panel.

Pretty cool stuff -- not particularly cheap (yet) at $5.15/watt, but better than we had before now...
