Do you have a sense yet as to what effect being east/west facing has on the generating capactiy of the installation? Our house is east/west, so I've always been a bit put off getting solar, under the impression that the efficiency would make it a waste of time. Although I guess that depends on how much extra it costs to have more panels as a proportion of the total cost. If you don't mind me asking, how much is this installation? I know that panel prices have dropped a lot, but I'm curious if the installation time/cost have dropped too.
