Understanding the financial projection

The projection are determined by the system cost, output and your financial settings - you can set the projection period, inflation rate, degradation rate and discount rate. You can also set how the import and export rates will change with inflation. Select Financial inputs in the top right to adjust these for individual projects and edit your financial settings for all future projects.

Summary info

This gives an overall indication of the benefits of the system and whether it is a worthwhile investment for the customer.

Generation: This is the total generation across the projection period, factoring in the degradation rate each year
Payback: This is how long it takes for the benefits of the system (savings on bills, earnings from exports) to outweigh the costs (initial cost, loan payments, maintenance costs)
Internal Rate of Return:
Net Present Value: This is the difference between cumulative benefits and the cumulative costs of the system across the projection period, both factoring in discount rate. A positive NPV indicates the system is a good investment

These figures are also given on the payment option pages of the customer proposal.

Payback period coming out longer than you'd expect? Read here for things you can do to help with that.

Income and savings

Electricity savings: this is how much we project the customer will be able to save now they will not be spending this on their electricity bill, using the annual generation and import tariff (using the customers old tariff if they are switching tariffs)
Export benefits: this is how much we project that the customer will be able to earn from exporting unused electricity to the grid
Additional savings: this models any additional savings that aren't factored into the MCS or Easy PV model

Note that if you have forced battery charging and discharging configured, you may find the electricity savings are negative. Provided the total income and savings is still greater than how much they were spending on electricity, this is not a problem.

Loan and running costs

The loan and running cost graphs will show any costs that they will incur in the first year and beyond. These will be factored into the total cost of the system across the period and used in the payback calculation.

If you have set up a finance option, you can select this from the right side bar to see the impact this has on the projection.

Bottom line

This section shows the year by year costs (red) and benefits (green) of the system, including any income, savings, running costs and finance payments. These will be plotted against each other - where the costs equal the benefits gives the payback period.
