About Solar Battery Planner
A free, independent planner that helps Australian households work out what size solar and battery system suits them.
Who runs it
Solar Battery Planner is run by Justin Graham, a sole trader in Sydney (ABN 63 320 272 207). It isn't owned by, affiliated with or endorsed by any battery manufacturer, installer, electricity retailer or government agency. Brand and product names on the site belong to their owners and are used only to identify the products described.

How we make money
The planner is free to use, with no sign-up. At the moment the site earns nothing. The plan is to add installer quote requests and clearly labelled sponsored placements later, and to be paid a fee for those. If and when that happens, this page will say exactly who pays us and for what. Payments will never change your recommended system size or the order of unsponsored results.
Where the figures come from
- Rebate rules and STC factors: the Clean Energy Regulator's Cheaper Home Batteries Program pages.
- Approved batteries: the Clean Energy Council approved list as published by the Clean Energy Regulator, refreshed weekly.
- Electricity prices: the 2026–27 regulated default or standing offers for each state and territory.
- Solar output: Clean Energy Council average daily yields for each capital city.
- Typical household use: the Australian Energy Regulator's residential consumption benchmarks.
- Installed prices: published market averages, listed on the results page.
Every result is an estimate from those published figures and a simple model of a typical home. The assumptions are listed on each page. Your bills, your roof and your installer's quote will differ. Rules and prices were last checked on 9 November 2026.
What we are not
We don't sell, install or finance anything, and we don't give financial, tax or legal advice. The site doesn't take your personal circumstances into account. For the final word on sizing, price and eligibility, get a site visit and a written quote from an accredited installer.
