Analysis & Commentary: "PV Costs to Power Cars"
(to calculate: click curser on, then off, yellow input cell)

  watts per square foot PV (full sun)
  hours sun per day (full sun equivalent)
  watt-hours per day per square foot PV
   
  miles driven per day
  miles per kilowatt-hour
  kilowatt-hours of recharge per day
   
  square feet PV required to recharge electric car
  watt output for full array in full sun
   
  cost per watt - installed w balance of plant
  PV system cost
  cost per kilowatt stationary battery storage
  storage system cost
  total system cost
   
  system lifetime (years)
  lifetime kWh produced
  lifetime mileage powered
  cost per kWh
  cost per mile



How to use this calculator:

(1) It is sometimes necessary to click on one of the yellow input cells, then click somewhere else on the screen in order to prompt the interactive spreadsheet to calculate and display results.

(2) Yellow cells are input cells - you may enter your own assumptions in these cells.

(3) When you refresh the screen, the original default assumptions will reappear in the yellow input cells.
