Consider a PV solar power project with the following parameters:

• Initial cost: $18M for hardware + $14M for installation.

• The yearly energy produced is 24 millions kWh which will bring an income of $2.9M per year

• $0.5M per year is used for operation and maintenance.

• At the end of the 25 year time horizon, a net expenditure of $1M will be required for removal and site cleaning.

• The MARR is 7%.

a) Calculate the NPV for this investment.

b) Recalculate the NPV, this time assuming that an investment tax credit of 20% for hardware and 10% for installation costs are available.

c) Calculate the IRR for this investment (with tax incentive).

d) Calculate the levelized cost of energy (with tax incentive)

Solutions

Expert Solution

Answer a.

Calculation of NPV-

= PV of net cash inflow - PV of net cash outflow

= 27.97 - 32.18

= $ -4.21 M

Cash flow = Income per year - Operating cost

= 2.9 - 0.5 = 2.4 per year

PV factor for 25 years = (1/1+r)^n1 + (1/1+r)^n2 + ......

= 11.6534

PV factor for 25th year = (1/1+r)^n25

= (1/1+0.07)^25 = 0.1842

PV of net cash inflow = 2.4*11.6534

= $27.97 M

PV of Cash outflow = PV of Initial investment + PV of Expenditure at 25th year

= 32 + 1*0.1842

= $32.18

Answer b.

Present value of tax credit will be included in the present value of cash flow-

Calculation of PV of cash credit-

= (18*20% + 14*10%)

= $5M

PV factor for 1st year = 0.9346

PV of tax credit = 5*0.9346

= $4.67 M

NPV = (27.97+4.67) - 32.18

= $0.46 M

Applying the IRR formula in excel on above table the IRR will be 7.25%

Answer d.

Levelized cost of energy = PV of total cost over the year / PV of electricity produced over the year

= 32+(0.5*11.6534) / 24*11.6534

= 37.83 / 279.68

= $0.13 M

Q2. Solar or photovoltaic (PV) cells convert sunlight to electricity and are commonly used to power calculators, satellites, remote communication systems, and even pumps. The conversion of light to electricity is called the photoelectric effect. It was first discovered in 1839 by Frenchman Edmond Becquerel, and the first PV module, which consisted of several cells connected to each other, was built in 1954 by Bell Laboratories. The PV modules today have conversion efficiencies of about 12 to 15 percent. Noting...
