I installed my own GRID Tied solar system in 2001 before incentives or net-metering. I then worked to get net-metering and am now working for FIT. I used to drive a plugin PHVE50, since St Paddys day 3-19-2011 we have a 100% electric LEAF. 140 mile range. Our 4Kw Grid tied Solar runs our home, Vehicle and still gets utiltiy credits each month !
