This is fantastic. Haven't looked at the solar pv for couple years. Didn't realize they have dropped so much in price. Does anyone know the current approximate total cost (labor + material) in Northern CA? It was like $8-$10/W last I looked couple years ago. Also how easy is a DIY approach in installation?
