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.
Revolve can model the property in Aurora, prepare the proposed equipment and scope, then give you a solar quote you can use when discussing finance with your lender.
