FAQ

Answers to the questions CFOs ask.

How accurate are the savings estimates? +

Our calculator uses CEC-approved solar sizing rules, actual AU 2025 tariff structures, and the latest rebate schedules (STC + Cheaper Home Batteries Program). Estimates typically land within ±8% of final quoted system economics.

Do you store my bill? +

The PDF is parsed in your browser — it never touches our servers unless you explicitly submit the report. We store only the extracted numeric data plus your contact details, encrypted at rest.

Does this work for all states? +

Yes. NSW, VIC, QLD, SA, WA, TAS, NT and ACT. The calculator auto-adjusts STC zone ratings, feed-in tariff averages, and typical commercial usage profiles per state.

I'm a solar installer — can I white-label this? +

Absolutely. UnaOne offers white-label licenses for installers Australia-wide with your logo, brand colours, pricing and lead routing. Call +61 405 270 694 or email info@unaoneshop.com.

What if the PDF doesn't parse correctly? +

We offer a manual entry fallback — just type in your consumption (kWh), billing days, and tariff type. Takes under 30 seconds.
