About AU Solar & Battery Payback Calculator

AU Solar & Battery Payback Calculator is a simple estimator for Australian households considering rooftop solar, with or without a battery. You enter your own system size, cost, household usage, and tariffs, and it estimates how long the system might take to pay for itself. It is not a quote from an installer and it does not replace advice from a licensed electrician or solar retailer.
