For nearly forty years, the conversation we have with households about solar has ended in the same place. Not “is it worth it”, because the answer to that has been yes for a long time. It ends at “we cannot find the money this year”. In June the NSW Government set out to remove that sentence from the conversation, and we are still working out how much it changes.
The Home Energy Saver program funds loans of up to $15,000 at zero interest, over as long as ten years, for solar, batteries, heat pump hot water, efficient air conditioning, EV chargers and a growing list of other home upgrades. Approved lenders, not the government, provide the money. There is no interest, no establishment fee, no account-keeping fee and no penalty for clearing it early. The only fee is a late payment fee if you miss a repayment.
This piece explains what that actually changes, and four mistakes we are already seeing people make. If you would rather skip to the eligibility rules, the repayment figures and how to apply, they are on our NSW Home Energy Saver page.
The short version
- Up to $15,000 at 0% interest over up to ten years, for NSW property owners on a combined income of $210,000 or less. The cap is per property, not per person.
- It is finance, not a rebate. It does not make your system cheaper. It changes when you pay for it.
- It stacks with the federal battery discount, which the rules require to be applied to the price first.
- A separate discount of up to $4,000 is coming later in 2026 for households under $80,000 and concession card holders. If that is you, that one matters more.
- Solar, batteries and EV chargers can only be supplied under it by a NETCC Approved Seller, using accredited installers, working with an accredited lender.
The shift is cash flow, not price
Solar has had a payback problem that has nothing to do with payback. A well-designed system pays for itself comfortably inside its warranty period. That was never the obstacle. The obstacle was that the payback arrives over years and the invoice arrives on Tuesday.
Zero-interest finance over ten years addresses that problem directly. It puts the cost and the benefit on the same timeline. Rather than finding several thousand dollars up front and waiting for the savings to catch up, a $12,000 upgrade becomes roughly $46 a fortnight sitting alongside a power bill that is going down.
Whether the repayment is smaller than the saving depends entirely on your household: how much you use, when you use it, what tariff you are on and how the system is sized. Nobody can tell you that from a web page, and you should be wary of anyone who tries. What we can say is that it is now a fair question to ask, whereas for many households it previously was not a question at all.
That is worth stating plainly, because the marketing around this scheme is going to get loud and most of it will be about the number $15,000. The number that matters is the fortnightly one, next to your own bill. It is why our quotes show both.
Mistake one: reading a loan as a rebate
The most common one, and entirely understandable, because it has arrived in the middle of a rebate cycle. The federal battery discount is a rebate. The old NSW battery incentive was a rebate. Home Energy Saver is not. It is a regulated credit product, with a credit assessment and an entry on your credit file.
Practically, that means two things. It does not reduce the price of your system by a dollar, so anyone presenting it as “$15,000 off” is either confused or hoping you are. And it is a commitment you should weigh the way you would weigh any other ten-year commitment, even at zero interest. Borrowing at 0% is close to free money in real terms, but free money you do not need is still a repayment you have to make.
Mistake two: taking the loan when you qualify for the discount
Home Energy Saver has a second half that has not opened yet: discounts of up to $4,000 for households on a combined income of $80,000 or less, and for eligible concession card holders. Expected later in 2026. The government’s own advice for households wanting both is to apply for the discount first, then borrow for what is left.
The distinction is not subtle. A discount is money you never repay. A loan is money you do. Get the sequence wrong and you could end up borrowing several thousand dollars you never needed to borrow, quietly, in a way most people would never discover.
We are saying this on our own website, knowing it will talk some readers out of buying from us this quarter. We would rather that than have a customer find out in November that they could have had four thousand dollars they did not have to repay. If you are anywhere near that income bracket, tell us when you call and we will help you work out the sequencing, including whether the federal battery discount step-down on 1 January 2027 tips the balance the other way.
Mistake three: assuming the government list is the list you can borrow against
This one is catching people out already, and it is the least obvious of the four.
The NSW Government publishes a generous list of eligible technologies: solar, batteries, heat pump and solar hot water, reverse-cycle air conditioning, ceiling insulation, double glazing, induction cooktops replacing gas, Level 2 EV chargers, draught proofing, ceiling fans, switchboard upgrades and NatHERS assessments. Read that list and you would reasonably assume you can walk in and finance any of it tomorrow.
You cannot, yet. Each lender decides which of those categories it has switched on, and the live lists are considerably shorter than the government’s. Insulation, double glazing and induction cooktops are on the program list but are still being brought online. Some categories aren’t offered by every lender. The gap between the two lists is where disappointed customers are currently being created.
Two further conditions are worth knowing before you plan around the program. A battery has to go on a property that also has solar behind the meter, so a battery on its own at a property with no solar is not eligible, though solar and battery together in one job is. And the EV charger category means Level 2 chargers only, not a lead to a power point. We keep an up-to-date version of what is actually financeable through us on our Home Energy Saver page.
Mistake four: assuming everyone advertising it can deliver it
Every incentive scheme in this industry has produced a similar pattern: a wave of new businesses, aggressive advertising, and a smaller wave of companies going quiet once the scheme does, taking their warranties with them. We have watched versions of it since the 1990s.
Home Energy Saver has a built-in filter, and it is genuinely useful. To put solar, a battery or an EV charger on your roof under this program, a business needs four things, not one: NETCC Approved Seller status, the right industry accreditation for the product (Solar Accreditation Australia for solar design and install, and for battery install), the appropriate electrical contractor licence, and a separate accreditation with the program’s lender. A business can advertise the scheme all it likes. If it has not walked through all four doors, the finance will not settle and you will find out late.
So it is a fair question to ask anyone quoting you, including us. Are you a NETCC Approved Seller? Are your installers SAA accredited? Which lender are you accredited with? What is your electrical contractor licence number? Ours are: yes, yes, Brighte, and 198555C in NSW. Any business that hesitates on those four has told you something useful.
What it means up here specifically
Two things about the Northern Rivers make this scheme land differently than it will in a Sydney suburb.
The first is outages. Households here do not buy batteries purely as a savings exercise. They buy them because the power goes out, sometimes for days, and because a fridge full of food and a working water pump matter more during a flood than a spreadsheet does. Batteries have always been the hardest thing to justify on payback alone and the easiest thing to justify the week after a storm. Interest-free finance closes that gap: you can make the resilience decision without the payback argument having to carry the whole weight.
The second is the shape of the housing. There is a lot of rural and semi-rural property in this catchment, a lot of older housing stock with tired switchboards, and a lot of homes where the sensible upgrade is not one thing but four. A $15,000 facility that can cover solar, a battery and a hot water heat pump in the same job suits that far better than a scheme that only pays for panels.
Worth flagging for the off-grid households reading this, and off-grid and hybrid work has been a core part of what we do since 1987. The program’s rules are written around grid-connected upgrades: a battery, for instance, has to sit at a site with a behind-the-meter solar system, defined by its metering identifier. If your property is off-grid or hybrid, the answer is not automatically no, but it is not automatically yes either, and nobody has published a definitive position. Ask us and we will give you a straight answer rather than a hopeful one, including when the answer is that we are still chasing it.
What we would do if it were our house
Roughly this order.
- Check the discount first. Under $80,000 combined, or holding a concession card? That component is worth waiting for. Everyone else, carry on.
- Plan the whole upgrade before you borrow a dollar. The $15,000 is a cap on the property, not on the loan. Once a property has drawn its $15,000, it cannot come back for a second one. Sequencing a big job badly is the most expensive mistake you can make here.
- Deal with hot water. For most households, it is the single largest electrical load in the house; a heat pump is the cheapest large saving available, and it is financeable today.
- Then solar, then storage. Sized against your actual usage rather than against a package someone wants to sell you.
- Come back for the fabric. Ceiling insulation and draught proofing reduce the size of everything else you buy, and they are on the program list. They are simply not financeable through every lender yet, so treat them as a second phase or pay for them separately.
- Mind the battery calendar. The federal battery discount now steps down every six months, in January and July, with the next reduction on 1 January 2027. It also tapers by capacity: the first 14 kWh attracts the full rate, and capacity above that attracts progressively less. On a large battery, those two rules together move the number considerably.
One more, less about money. Do not borrow the full $15,000 because it is available. Borrow what the right system costs. The facility is generous enough that the temptation to fill it exists, and a system sized to a loan limit rather than to a household is a system that disappoints.
Where to go next
The eligibility conditions in full, the fortnightly repayment figures at every loan size, what is financeable through us today and how the application runs are all set out on our NSW Home Energy Saver page. The battery side of the equation, including how the federal discount is calculated and what the step-down and the capacity taper cost you, is on our Federal Battery Rebate page. The government’s own information, including the loan guidelines, sits on the NSW Climate and Energy Action website.
And if you would rather talk it through with someone who’s watched every one of these schemes come and go since 1987, that is what we are here for.
