The above megawatt estimated requirements are for the replacement of energy and fuels consumed for electricity, heating and cooling, gasoline transportation fuels converted to its electric megawatt equivalent utilizing solar PV. We utilize Hawaii's minimum annual ideal weather 30-year monthly-averaged useful daily hours of solar concentration. These conversions would be Hawaii's approximate energy demand equivalents in terms of energy, land, and cost. For this conversion data set, one solar PV megawatt is equal to approximately six acres. However, other solar PV installations are currently utilizing up to ten or more acres per installed megawatt. There are thermal solar installations utilizing 44 acres per installed megawatt. ("resulting in a land-to-power ratio of 44 acres (180,000 m ) per 1 megawatt.") ref; Thermal Power Towers - "Power Tower Designs" wikipedia

This installed PV solar energy estimate does not include land cost, taxes, additional infrastructure, or any other cost. And, additional at-load losses when the solar collection minimum service hours can not be met because of less than ideal weather, nor the cost of future growth.
Note; The replacement of gasoline combustion vehicles replaced by electric vehicles would have net reduction of energy effect of approximately 1,255 megawatts per hour. (Example; Chevy Volt automobile with a rating of 100 miles per 38 kilowatt hours with an 80% recharge in 20 minutes.) This would have a net reduction of 11,002,936 mWh's annually and 5,522 installed megawatts on 33,132 acres. Currently Hawaii consumes 405,975,491 gallons of gasoline annually which is equivalent to 14,858,703 megawatt hours. Electric vehicles similar to the Chevy Volt would only utilize about 3,856,767 megawatt hours for the same rated miles when compared to an automobile combustion ratio of 25 mpg for a total of 1,014,387,275 miles driven in Hawaii. This would also have the affect of reducing the consumption of gasoline in terms of energy by 300,872,568 gallons of gasoline. This would also reduce the equivalent of 2,903,420 tons of carbon dioxide emissions. One gallon of U.S. automotive gasoline is equivalent to 36.6 kilowatt hours of electricity.
