We're a young service, so we have no wall of five-star testimonials to show you. We won't buy one and we won't invent one. What we can show you is arithmetic: the verified numbers behind Australia's battery boom, and worked rebate receipts computed from the same data files that power our calculator.
Battery figures: Clean Energy Regulator data, to 1 July 2026; "1 in 17" is derived from it.
This is the honest social proof: not our numbers, Australia's. Every figure is sourced, and the source is one click away.
Three worked examples, computed from the current federal factors and verified state programs. When a rate changes, these change the same day.
Government-estimated saving: up to $1,100/yr

Source: DCCEEW ministerial releaseThe system does not get cheaper in January. The rebate gets smaller.
Source: Clean Energy Regulator, SRESThe government's own estimate for a battery on existing solar is up to $1,100/yr. At that upper figure, the 13.5 kWh battery in the Sydney receipt ($10,498-$12,598 after the federal discount) takes about 9.5 to 11.5 years to pay for itself. That is the fastest case: it assumes the full estimated saving every year, no VPP income, no state incentive and no change in power prices. A smaller saving means a longer payback. General information, not financial advice.
This page used to be called "Reviews". It isn't anymore, and here's why: we launched recently, and genuine customer reviews take years to earn. Plenty of solar lead sites fill that gap with invented testimonials, purchased star ratings and fake "12,000 happy customers" counters. That's misleading conduct under the Australian Consumer Law, it breaches Google's structured-data spam policies, and it's exactly the kind of thing we'd warn you about in a solar quote.
So instead of pretending, we publish what we can actually stand behind: government program data, computed rebate maths with the formula shown, and savings estimates that are attributed to whoever made them. When we have real, verifiable first-party reviews, we'll publish them here, named, dated and checkable. Not before.
Every figure on this site carries its source. If you find a number we can't back with a link, tell us through the quote form and we'll correct it the same day.
The federal solar rebate is system kW × STC zone rating × deeming years × STC
price, floored per the regulation. The federal battery discount pays 6.8 STCs
per usable kWh (through 31 December 2026) on the first 14 kWh, tapering above. We value
certificates at the current spot price of $39.65; your installer's pass-through is
typically a few dollars less per certificate. State incentives are listed only where
the program is verified as open.
Installed prices come from our own battery price table and are planning estimates, not quotes. Your roof, switchboard and hardware choice move the number, which is why the calculator asks for your postcode before it shows you anything.
