But theperformance of the batteryclearly supports its promise asa major component of futuresolar PV systems that requiresome measure ofdispatchability.

Florida Gulf Coast University Renewable Energy InstituteSolar Economics!!! Is Solar too expensive for the Sunshine State? The cost of a PV system today: (very approximate figures)oooooo 0.85/watt for the modules 0.25/watt for the inverter 0.10/watt for other electrical components 1.50/watt for installationTOTAL 2.70/watt installed (2012) Today - 2.00/watt (NO REBATES)A good installer will produce 2,000kWh/kW (AZ) and 1,500kWh/kW (FL)annually. This translates to 1.35/kWh (AZ), 1.80/kWh (FL)o If amortized over 20 years, then the cost per year is well below the retailprice of electricity ( 0.12/kWh – grid price)Solar AZ - 0.07/kWh and Solar FL - Bio0.090.110.070.100.110.100.07*0.310.100.11Energy Information Agency 2011except for Solar PV
