What matters beyond the headline rate

Compare the loan and the solar system together.

Low-rate periodCheck what happens when the promotional period ends and whether you intend to clear the balance before then.

Borrowing limitBattery storage, switchboard work, EV charging and hot-water upgrades can change the total project value.

Equity & eligibilityMost products are home-loan top-ups and have lending, equity and property requirements.

Quote requirementsSeveral banks require a valid quote or invoice from a qualified installer before funds are released.

Make the finance useful

Get the system designed first, then take a real number to your bank.
