In order to make it easy, we listed the explanation of the terms that are used in this amortization table . You can find the details of the headings of the different columns:

  1. Year: The year in this case, starts on 5th of May and finishes 4th of May in the following year.
  2. Savings: The amount in this column indicates the savings from the bill based on consumption. The calculations include the electric price increase each year.
  3. Surplus Sale: In this case work, the client is able to produce more than the electric usage. Due to this, there is a surplus he can sell each year. The amount in this column indicates the surplus sale of the electric.
  4. Net Profit: This column represents the total amount the client saves each year with the solar energy system installation.
  5. Capital Outstanding: This column indicates the remaining balance of the investment until the it pays off itself. After the payback period, it is the total of savings from this investment over 30 years.
  6. Income Rate: This column indicates the percentage of net profit in initial investment. It is the yearly rate of return to your initial investment.
