Folks: I am in NJ and had a 5Kw solar system installed on my roof in 2005. Back then, the installed cost was $8.50 per watt. With the State and Federal incentives the final cost came to about $4.00 per watt. Now I understand the going price per installed watt now is about $7.50 before any incentives. The numbers from National Labs are not intended for average home type installations, rather for commercial installations with a hell of a lot of negotiating power because of the size.
