Assuming 120W Solar Cells obtaining on average 8 hours of sunlight per day*  Year2014 Consumption→  552,365 / 8 hours of sunlight = 69,045.63  How many Solar panels should we need to meet 100% of  VanWinkle’s electricity needs: 69,045.63 / (120/1000) = 575,380.25 | 575,380.25 ~ 120W panels|Assuming the $115.15 cost per 120W panel, [115.15 X   575,381 = $66,255,122.15] to meet the buildings needs would be not be feasible.|On the other hand, if we would be eager to provide solar energy we can settle to provide 15.09% of the current energy needs. | .1509 * 552,365 = 83,369kWh |  83,369 kWh/ 12 months = 6,947.45 kWh to be produced through solar per month.  Assuming once again the conservative estimation that the panels will be actively working 8 hours each day, and that our Target kWh are 83,369 per year,  it will be safe to assume that we need to obtain   [83,369 / 8hr = ] 10,421.125 kW from the solar array.  Lastly, to obtain this amount of kW’s we would need [10,421.125/ (120/1000) ] 86,842 PV Cells. Costs per windmill equivalent to $350,000.|140kWh  yearly output per windmill (Assuming 70% efficiency)|$60,000 yearly payments for average 20 year life cycle of wind mill.PenFed APR Interest rate of 3.6%|Apply Financial Assumptions:l PV: $410,000 + PMT: $60,000 + I/Y: 3.6% + N: 20Yrs = Future-Value:$882,599.63/windmill.$882,599.63*2]=$1,765,199.26.280,000Wh/552,308.25=50.72%|10,000,000.00-$1,765,199.26 = $8,234,800.74 Total Budget left.|$8,234,800.74 / $115.15 cost per 120W PV cell = 71,513.68 | 71,513 PV Cells.  71,513 * (120/1000) =8,581.56 kW from solar array| 8,581.56 kW * 8 = 68,652.48 kWh| 68,652.48 / 552,308.25 = 12.43%
