2009-11-10 Thread Marco Mangelsdorf
The common metric for many consumers when considering a PV system purchase is the $/watt cost of the installed system. This misleading metric allows low-priced bottom feeders (those licensed and unlicensed contractors working out of their garage or storage spaces) to clobber those of us who pay
