salvage value total annualized cost

S is the salvage value, C ann,tot is the total annualized cost, C rep is the replacement cost of the component i the annual real interest rate (discount rate)R rem the remaining life of the component R proj the project lifetimeR comp the lifetime of the component. CRF capital recovery factor

Sample :

1 Project lifetime (years) 20PVarray lifetime (Years) 20

S = 0

2 Project lifetime (years) 30PVarray lifetime (Years) 20(30-20) / 30S = (1 / 3) x C rep

3 Replacement Cost ($) 750000Project lifetime (years) 25PVarray lifetime (Years) 0

S = 0

total annualized cost capital recovery factor

is the total annualized cost, N is the number of years the annual real interest rate (discount rate) i the annual real interest rate (discount rate)

capital recovery factor sample :1 I = 7%

N = 25CRF = -0.93

Discount Factor

N  is the number of years since year zero

The discount factor is the number by which you multiply a future cash flow to obtain its present value

E prim the total amounts of primary load that the system serves per year, E def the total amounts of deferrable load that the system serves per year, E grid;sales amount of energy sold to the grid per year.

Equation to calculate the levelized cost of energy:

Above equation is an expression of the total amount of useful energy that the system produces per year. The levelized cost of energy is therefore the average cost per kilowatthour of useful electrical energy produced by the system
