01
Upload your bills
One to three recent months is enough. We read usage, tariff timing, and what you actually paid.
For Australian households
See what your electricity bills are really saying.
BillZero is a place to understand solar and your power bill — starting with a free energy reading from the bills you already have, and the household questions we answer below.
- From your bill
- Energy money map
- From your roof
- Physical capacity
- What we won't do
- Invent a payback
How it works
A reading first. A sales pitch never.
02
We map the energy, not a pitch
When you buy expensive electricity, what your roof can physically fit, and what we still need before anyone sizes a system.
03
A reading you can keep
No invented payback. You get a clear picture — and we only contact you if you asked us to.
The first tool
Get your energy reading
Upload 1–3 months of your utility bill. Takes about a minute. The bill file is read in memory and never stored — the consent on the form says what happens to the details you enter.
Learn
Solar, in plain English
The next layer of BillZero is household guides — tariff explainers, rebate basics, and answers you can read before you talk to an installer. These are placeholders for that library.

How time-of-use tariffs actually work
Peak, shoulder, off-peak — and why the same kWh can cost you twice as much after 4pm.

What an STC discount is doing on a quote
The federal rebate in plain English, and how to tell a real discount from a rearranged price.

Battery or no battery?
When storage helps a household, when it is mostly a sales add-on, and what your bill has to show first.
FAQ
Questions households actually ask
Do you store my bill?+
No. The bill file is read in memory to produce your reading and then discarded — it is never written to storage. Your address is used once, to look up roof capacity.
What happens to the details I enter?+
They are used to send you the reading and for follow-up on your enquiry, including by the installers or retailers who can quote the work — the consent you tick before submitting says exactly that.
Is this a solar quote?+
No. It is an energy reading: what your bills are doing, what the roof can hold, and what is still missing before anyone should size a system. We do not sell or install anything.
How many bills should I upload?+
One month works. Two or three months give a clearer picture of how your usage and rates move.
Will more articles and FAQs show up here?+
Yes. BillZero is being built as a place for everyday solar questions — tariff explainers, household guides, and answers you can read before you talk to anyone.
