Understanding the financial projection

This guide applies to easy-pv.ie and easy-pv.co.uk versions of Easy PV. The information provided here may not be accurate for easy-pv.com.

Projection page

Summary info

Generation: This is the total generation across the projection period, factoring in the degradation rate.
Payback: This is the year that the system has paid for itself: when the cumulative costs equal the cumulative benefits.
Internal Rate of Return:
Net Present Value: This is the cumulative benefits of the system across the projection period subtracting the cumulative costs, both factoring in discount rate.

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

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 this has been configured),
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 benefit (from 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.

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.

Discount rates
A discount rate is a means
