Solar Battery Planner (ABN 63 320 272 207) is independent: not owned by, affiliated with or endorsed by any battery manufacturer, installer, electricity retailer or government agency. Brand and product names belong to their owners and are used only to identify the products described.

Everything here is general information and an estimate based on the assumptions shown on each page. It doesn't take your personal circumstances into account and isn't financial, tax or legal advice. An installer's site visit and quote give the final figures. Rebate figures assume $38 per STC and installation in the current period; your installer sets the STC price they credit and may deduct fees. Rebate rules and state schemes as at 9 November 2026.

The planner is free to use and currently earns nothing. If that changes, we'll say so on the About page.
