Marco:

Good point, but how does a consumer quantify the expected long term harvest
and reliability of a solar electric system?  Smooth talking sales people
will assure customers that the lower priced system is of equal value as the
name brand system offered by an established installer.

They know the difference.

But when it comes down it, what really matters to the consumer is not the
$/watt installed cost but the kWhs produced by the system over time.  For
what good is a cheap PV system if its output is poor?
