Don't wait to get solar, you can start saving with $0 upfront!

Assumptions & sources

Uses 5.5 sunlight hours per day and a 91.25-day average quarter. Usage is estimated from your bill after supply charges at 31c/kWh. Solar offsets that usage first at 31c/kWh; generation above that usage is exported at the assumed 9c/kWh rate. This simplified model ignores when electricity is used. Quarterly balance = remaining grid usage + supply charges + finance repayments − export credit. Weekly figures use 13 weeks per quarter. Export credit reduces your modelled net cost, not the amount owed to the finance provider.

10-year savings compare 40 current quarterly bills with 10 years of modelled bills after solar value and finance payments. Repayments and monthly fees stop at the chosen loan term. If the loan extends past 10 years, only the first 10 years of payments are included; any remaining loan balance is not deducted. The model holds your bill, solar generation and entered interest rate constant.

Supply charges are included in the bill you enter and are not added twice. Prices include GST, with no deposit. Starting bill and system price are examples; the price does not change automatically with solar size.

Excludes generation timing, system losses, seasonal variation, degradation, maintenance and future tariff changes. This is a scenario estimate, not a bill forecast or finance offer.
