Speaking of grid-tied yuppies and sustainability-oriented poor folks: 
    Getting RE out into the world is a good thing.  In the suburbs, it helps to get the word out to the neighbors that  PV works; especially noticeable when the power goes out.  It is also helpful in getting the people who buy these systems more in-touch with their energy usage.  They start to notice how much power they're really using, as well as weather patterns and the annual solar cycle.  A PV system makes one pay more attention.
    In the boonies, people are setting good examples of how to live lightly and simply.  That's more my crowd.  Unfortunately, many of these people can't afford top-notch PV systems.
    I propose a "Robin Hood" approach to the problem.  Or call it a "sliding scale".  I've operated under this system in my regular electrical business for 8+ years now, and it seems to work out.  As soon as I leave my own Weld County, and enter Boulder County, my hourly rate automatically goes up $10.00 per hour.  I charge the highest possible, but still competitive rate to those who can afford it.  On the other hand, I often give discounts to those who can't afford my services but really need them.  I think that it balances out overall.  No one is cheated or "taken to the cleaners", and I still earn a living.  Ain't as easy as it sounds always, but kindo' works as a general guide.
