| Net Present Value | $ 13,045,300.56 |
Net present value is the difference of Sum of Present values of cash inflows and Sum of Present values of cash outflows. If the value is positive then the project may be accepted. While evaluation of two or more alternatives takes place, then the proposal with the higher net present value may be selected since it results in a greater cash inflow over the duration of the project.
In the given scenario, Present values are calculated by calculating the present values of cash inflows in the form of revenues in the form of electricity and cash outflows such as installation cost and operating cost.
Installation Costs in case of Flat Solar Panels are $87 Million, Mechanized Solar Panels + $101 Million and Solar Collector Field + $91 Million.
Annual Operation and Maintenance costs for year 1, in case of Flat Solar Panels+ $2 Million, Mechanized Solar Panels + $2.3 Million and Solar Collector Field + $3 Million.
Increase Annual Operation and Maintenance costs year 2 onwardsin case ofFlat Solar Panels+ $250,000, Mechanized Solar Panels + $300,000 and Solar Collector Field + $350,000.
Annual Revenues in the form of Electricity in case of Flat Solar Panels + $6.9Million, Mechanized Solar Panels + $8.8 Million and Solar Collector Field + $9.7 Million
Annual Increase in Revenues is 8% in case of all alternatives and the Useful Life is 20 Years. Rate of Interest for calculation is considered as 10%
Present value factor is calculated as 1/1.10 ^ N where N is the year of operation.
Conclusion:
Hence the option to be selected is Flat Solar Panels since it results in higher overall cash flow for a period of 20 years.

Suppose that a power plant dumps byproducts into a nearby river, creating a negative externality for those living downstream from the plant. Producing additional electricity imposes a constant per-unit external cost of $490. The following graph shows the demand (private value) curve and the supply (private cost) curve for electricity. Use the purple points (diamond symbol) to plot the social cost curve when the external cost is $490 per unit.
