A buzzword that's suddenly everywhere
If you've scrolled past a solar ad on Facebook lately, or typed anything about solar panels into Google, you've probably seen the phrase "No Net Solar" pop up. It's trending hard right now, often sitting alongside promises like "free solar," "no net cost solar" and "interest free solar."
It sounds exciting, and in some cases it genuinely points to real savings available to Australian homeowners. But the term has also been hijacked by dodgy marketers to push offers that are, frankly, too good to be true. This guide breaks down exactly what "No Net Solar" means, which parts of it are real, where it's been used to scam people, and how to actually access the legitimate savings on offer.
So what does "No Net Solar" actually mean?
"No Net Solar" (and its cousins "free solar," "no net cost solar" and "interest free solar") describes a system paid for entirely through savings, rebates or finance, so the homeowner never feels an out-of-pocket cost. The idea is that your energy bill savings, combined with upfront discounts, cover the repayments, meaning the solar "pays for itself" and your net cost is zero.
In marketing terms, it's shorthand for: "We'll find a way to fund this so you don't have to reach into your own pocket." That funding usually comes from one (or a combination) of three things:
The problem is that "no net cost" has been stretched by some marketers to mean something it isn't: a government handout that makes solar completely free, no strings attached. That's the part that isn't true, and that's where the scams come in.
But there's a grain of truth here: real savings do exist
Here's the part that keeps the myth alive: there genuinely are legitimate ways to get solar and batteries at a heavily reduced, and in some specific cases close to zero, net cost. They just don't work the way the ads imply.
Government rebates and incentives (real, and stackable)
The federal Small-scale Renewable Energy Scheme gives households and businesses certificates worth roughly 30% off a solar system, and the Cheaper Home Batteries Program offers a similar discount on battery storage. The Clean Energy Regulator has confirmed these schemes can be combined with state incentives to heavily discount a system, but not wipe out the cost entirely. On top of the federal schemes, states run their own support, for example NSW's Home Energy Saver program offers a zero-interest loan of up to $15,000 for most households (income up to $210,000), plus a separate discount of up to $4,000 for lower-income households and concession card holders, expected to open later in 2026.
Interest-free loans
Several state governments offer genuine zero-interest loans to spread the (already-discounted) cost over several years, so there's no interest bill stacked on top. This is real and can make a system cash-flow neutral or close to it, but it isn't the same as the system being free: you're still repaying the principal.
Power Purchase Agreements (PPAs)
Under a PPA, a third party installs and owns the panels on your roof, and you agree to buy the power they generate at a set rate, usually below grid prices. There's no upfront cost and no loan, which is why it gets marketed as "no net cost solar." It can suit some households, but it comes with trade-offs worth understanding fully before signing: you don't own the system, the contract can run 10–25 years, and the savings are generally smaller over the long run than owning your own system outright. It's worth comparing the full terms carefully (or getting independent advice) before committing to one.
Stacked together, these can get the net cost of a system very low. What none of them do is make solar panels appear on your roof for "absolutely no net cost" just because you live in the right postcode, which is exactly the claim that's been debunked.
Where the "No Net Solar" keyword has been used to scam Australians
The clearest case study is Solar Sprout AU, a Facebook page that ran a wave of near-identical video ads across multiple Australian cities. The voiceover claimed that if you lived in an approved postcode, solar companies were obligated to give you panels "for absolutely no net cost" under a supposed "2025 Renewable Energy Scheme," and all you had to do was fill out a questionnaire.
AAP FactCheck investigated the claim and found it was false. There is no government scheme or mandate forcing solar retailers to install panels at no upfront cost. The Clean Energy Regulator confirmed the real schemes discount systems by around 30%, but stacking incentives wouldn't result in a genuinely no-net-cost system. Energy policy experts from UTS and Macquarie University also confirmed no such rule, or city-specific scheme, exists. When AAP FactCheck completed the linked questionnaire itself, the page it landed on actually contradicted the ad's claim, saying the homeowner "may then receive an offer" for a no-net-cost installation, a world away from a guaranteed free system. No business address, phone number or genuine reviews could be found for the company.
The Consumer Action Law Centre called out the campaign publicly, noting it appeared designed to harvest personal information using AI-generated content and high-pressure "hurry, do it now" messaging, and warned Australians to avoid or delete the ads rather than engage with them. The Cool Down covered the story too, highlighting that genuine renewable energy support should come through verified, transparent channels.
This isn't an isolated incident. SolarQuotes has also reported on door-knockers and Facebook ads falsely claiming the government is giving away "free solar and batteries" due to an energy or oil crisis, and on misleading claims that the Federal Battery Rebate is about to disappear entirely. In reality, the rebate is simply stepping down on a scheduled timeline through to 2030. Scarcity language is being used to rush people into signing before they've compared offers.
Red flags vs. the real thing
Use this as a quick check the next time an offer lands in your feed or on your doorstep.
If you see any of the red flags above, the safest move is to not engage with the ad, and instead check the claim directly against official sources like the Clean Energy Regulator or your state energy department.
What's actually available right now in Australia
These are real, government-run programs you can check and apply for directly:
Small-scale Renewable Energy Scheme (federal)
Certificates worth roughly 30% off a solar installation, administered by the Clean Energy Regulator.Cheaper Home Batteries Program (federal)
A similar discount, roughly 30% off eligible battery systems, with full support for the first 14 kWh of capacity and reduced support above that. The program runs through to 2030, with support stepping down on a published schedule. It is not disappearing, despite some marketing claiming otherwise.NSW Home Energy Saver
A discount of up to $4,000, or a zero-interest loan of up to $15,000, for eligible NSW households and landlords (renters cannot participate) upgrading to solar, batteries and other efficiency measures. Renters can apply for the separate $4,000 discount once applications open, with landlord permission. Full eligibility and details are on the NSW Government's energy site and in this ministerial announcement.Other state-based rebates
Most states and territories run their own solar and battery incentives on top of the federal schemes. SolarQuotes maintains an independent, regularly updated list of current rebates and subsidies by state, which is a useful cross-check against anything a company tells you.Stacking the federal schemes with a state-based discount or zero-interest loan is how the net cost of a system gets pushed right down, sometimes dramatically, without anyone needing to invent a fake government mandate to explain it.
How Solar Battery Group helps you access this, transparently
We'd rather show you real numbers than a buzzword. When you get a quote from Solar Battery Group, we walk you through exactly which government rebates your system qualifies for, what they're worth in dollars, and how that reduces the upfront price.
Where it makes sense for your situation, we can also connect you with genuine zero-interest loan options so the remaining balance is spread out without extra interest cost. We lay out the full cost, the full rebate, and the real net price in writing, so you can see precisely how close to "no net cost" your own system can get, based on your roof, your usage and the incentives you're actually eligible for, not a one-size-fits-all script.
Your journey to zero bills
"No Net Solar" isn't a myth invented from nothing. It's a real possibility built from genuine rebates, interest-free loans and (for some households) PPAs, stretched by opportunistic marketers into a false promise of free panels handed out by the government. The truth sits in the middle: with the right combination of incentives, many Australian households can get solar and battery storage at a very low net cost. Getting there just takes a proper quote, not a Facebook ad.
