One thing I did not see mentioned, particular to the Bay Area.
We get a lot of morning fog certain times of the year, like right now for instance. If you have to put panels facing east and west, the west facing panels will produce more on those days when the "marine layer" burns off about at noon than your east facing ones will. Solar City recently did a split install across the street, and they put more east panels in then they did west. I suppose it would make the two sides produce about the same over a normal (foggy) summer day, but I think the overall output would be smaller...
