I see lots of mention of the time for "payback" for installing solar and eliminating the cost of utility provided electricity. In calculating the payback period, is the present and future value of the initial investment factored in with an internal return if invested elsewhere for 10 years?

For example. If I take $10,000 and invest it today at an average return of 5% yearly, in 10 years that $10k would then be worth $16,470.10. Would the initial $10k investment save $6,470.10 over 10 yrs.?
