The purchase price of an old solar panel array eight years ago was $181,000. A new array with 1.42 times the capacity is being consider for purchase. The cost index for panels was 162 eight years ago and is now 221. If the cost capacity factor is 0.8 and you will add $28,000 in optional features this time, which were not purchased eight years ago, what is your estimate of the purchase price for the new solar array? The support system for the old solar panel array cost $20,400 eight years ago. The cost index for that type of equipment was 125 and is now only 105 due to changes in design making the systems easier to install. However all the good bits of land on the property have been used and only rocky terrain is left, which will require more struts per m2 than the old system. If the new system requires 1.25 times as many struts as the old and the cost estimate is $22,903 what does the cost capacity factor work out to be? Explain why your cost capacity factor makes sense or why it doesn't
