This calculator provides estimates only and does not constitute financial, tax, or legal advice. Actual savings, payback periods, and rebate amounts depend on your specific usage, solar generation, electricity plan, and the WA Battery Scheme/STC rules current at the time of purchase — figures shown here may not reflect current rates.
Consult a licensed installer, financial adviser, or your electricity retailer before making a purchase decision. WattMate is not responsible for financial decisions made based on these estimates.
