Profit includes depreciation, while cash flow deducts the full investment in year 0 and yearly maintenance afterwards. NPV discounts flows from year 1.

Glossary

NPV (Net Present Value): The sum of all future cash flows from the investment, discounted to today's value at the discount rate, minus the initial investment. A positive NPV means the investment creates value — the higher, the better.
IRR (Internal Rate of Return): The annual return at which the NPV equals exactly zero — the effective "interest rate" the investment earns. If the IRR exceeds the discount rate (your cost of capital), the investment is profitable.
Payback period: The time it takes for the cumulative cash flow to cover the initial investment — the moment the cell has "paid for itself". A shorter period means lower risk.
Capital turnover: The ratio of the sum of all cash flows over the horizon to the initial investment. It shows what share of the invested amount has come back within the horizon — above 100% means it has been fully recovered and more.
