| Keywords: US Economic Solar PV Capacity vs Installation Cost.png en The United States uses about 4 trillion kWh/year of electricity at rates from 0 01/kWh to 1 00/kWh with an average of about 11 2¢/kWh The chart shows how many gigawatts of solar power can be installed economically i e cheaper than grid rate vs the installation cost both with the 30 federal tax credit ITC and without For example with the ITC at 5/watt 5 000 megawatts can be economically installed close to the total that has been installed as of early 2012 at a time that U S residential installations were averaging about 5 20/watt At 4/watt this increases to 33 000 megawatts at 3/watt to 308 000 megawatts and at 2/watt to 816 000 megawatts Without the ITC no photovoltaics can be economically installed if the cost is above 5/watt and at 1/watt almost the entire country can economically install photovoltaics both with and without the ITC Data is from https //ases conference-services net/resources/252/2859/pdf/SOLAR2012_0630_full 20paper pdf A graph showing the method used is at http //www keiser-analytics com/graph html 2012-06-30 own Delphi234 cc-zero Uploaded with UploadWizard Energy costs Solar energy schemas and diagrams Solar energy in the United States | ||||
