Frequently asked questions
What do I need to get started?
12 months of electricity bills as PDF or photos. Most retailers let you download these from their app or website.
Is this free?
Yes. This tool is completely free to use. We don't sell your data or require an account.
How accurate is the estimate?
We show confidence levels and all assumptions used. Final economics depend on installer pricing, roof conditions, shading, and your specific retailer plan. We recommend getting quotes from licensed installers.
What happens to my uploaded bills?
Your files are processed in memory and never stored on our servers. Only the extracted data (usage numbers, not images) is kept temporarily. You can delete everything at any time.
Which states are supported?
All Australian states and territories: NSW, VIC, QLD, SA, WA, TAS, ACT, and NT.
What if I already have solar?
If we detect existing solar from your bills, the analysis will adapt to focus on battery options or system optimization.
How long does the analysis take?
Usually 2–5 minutes. Bill extraction takes 30–90 seconds, then you review the data and get your results.
Can I edit the extracted data?
Yes! The review step lets you correct any values. Click any cell in the table to edit it.
