Return rate of solar power plants

What is the net present value of a solar energy system?

The Net Present Value, of the difference between the photovoltaic system’s energy cost and price, determines the IRR. The IRR defines the amount of profit investors’ gain by investing in a solar energy system—as a percentage. For example, an IRR of 12% means the investor makes a profit of 12% per year on any funds invested in the project.

What is a good IRR rate for a solar project?

While there’s no definitive “good” IRR rate, industry benchmarks can provide a general reference point. According to various reports, the average IRR for commercial solar projects in the United States can range from 10% to 15%. The best approach to determining a good IRR for a solar project is to consider the unique circumstances of your project.

What is the internal rate of return for a PV system?

The formula for the internal rate of return for a PV system includes the following components/definitions: PV system cost, First cost subsidies, PV energy cost and Secondary Market Characteristics and PV energy price. PV system cost (PVsys) equals the installed cost of the photovoltaic system.

How do I calculate IRR for a solar energy plant?

If you want to calculate IRR for a solar energy plant, assemble all the assumptions and variables that impact your project. Note that a major input is the price per kilowatt-hour charged by the local utility company. Let’s try a simple example.

Should you invest in a solar energy plant?

Investing in a solar energy generation plant creates dividends in the form of cash, no longer paid to the utility supplier. A solar energy system has an internal rate of return, with a yield, higher than most investments. Electricity Rates and Inflation Historically, electricity prices trend up due to inflation.

How do you determine the financial viability of a solar energy system?

To determine the financial viability of a solar energy system means factoring in future electricity rate inflation into the equation. The higher the assumed rate of inflation, the quicker the payback, and the higher the IRR on the money invested into the system.
