Question

Two methods can be used to produce solar panels for electric power generation. Method 1 will have an initial cost of $740,000, an AOC of $190,000 per year, and $135,000 salvage value after its 3-year life. Method 2 will cost $870,000 with an AOC of $135,000 and a $170,000 salvage value after its 5-year life. Assume your boss asked you to determine which method is better, but she wants the analysis done over a three-year planning period. You estimate the salvage value of Method 2 will be 37% higher after three years than it is after five years. If the MARR is 14% per year, which method should the company select

Answer 1

method 2 should be selected

Step-by-step explanation:

The computation is shown below:

For Method 1

Value = $740,000 + $190,000 ÷ 1.14 + $190,000 ÷ 1.14^2 + $190,000 ÷ 1.14^3 - $135,000 ÷ 1.14^3

= $1,089,988.93

For Method 2

Value = $870,000 + $135,000 ÷ 1.14 + $135,000 ÷ 1.14^2 + $135,000 ÷ 1.14^3 - $170,000 × 1.37 ÷ 1.14^3

= $1,026,219.458

As we can see that in the method 2 there is a less cost as compared with method 1

So, method 2 should be selected
