The cashflow table shows the annual and cumulative cash flows for your customer. The red numbers in parenthesis indicate a negative cashflow and the green numbers represent a positive cashflow.
In a cash example, you will see a large negative in the annual cashflows column in year zero for your payment in full for the system.
Annual cashflows after year 0 will be positive to reflect utility bill savings each year. Depending on the inverter life, you will see a negative value in the annual cashflows when the inverter will need to be replaced.
In the cumulative cashflow column the values will show negative until the end of the payback period, or the time at which their savings have outweighed their investment cost.
In a loan example, you should be cashflow positive for the entirety of the loan with the exception of the cost of inverter replacement. This is the case when your annual utility bill savings is larger than your loan payment amount. There will be no payback period in this case. For more information on payback period click here!
