The NSW interest-free solar and battery loan: up to $15,000 over 10 years

What is on offer

The NSW Government is offering eligible households an interest-free loan of up to $15,000, repayable over up to 10 years, to install solar and battery systems. Zero 4 Energy arranges it as part of your quote. You repay only what you borrow - no interest, no establishment fee - which on the full amount works out at roughly $125 a month over the full term.

That last number is the point. For a large share of Sydney households, the repayment is smaller than the portion of the electricity bill the system eliminates. The system is, in effect, paid for by the bill it replaces.

How it stacks with the rebates

The loan is not instead of the incentives - it sits on top of them. Your STC discount reduces the price of the solar; the federal battery rebate reduces the price of the storage; what is left is the amount you can finance interest-free. On a combined system that can mean financing a fraction of the sticker price at zero cost of capital.

It also changes the payback arithmetic. A system bought with cash returns its cost over several years; a system financed interest-free is cash-flow positive from the first month if the repayment is below the saving. Our payback article covers the mechanics; the loan simply removes the upfront hurdle.

Eligibility, honestly

Conditions apply. The program sets criteria around the household, the property and the system, and those criteria are the government's to define and to change. We do not publish a checklist here because a stale one would mislead more people than it helps - instead, we check your eligibility at quote time and tell you plainly whether you qualify.

If you do not, you will not be left guessing: we will say so, and show you the standard finance options alongside. If a conventional product would actually serve you better - shorter term, different structure - we will tell you that too. We are not a credit provider and do not give credit advice; the loan is provided under the government program and its terms.

What to check before you count on it

Three things. First, that the retailer arranging it is an accredited one - programs like this typically require it, which is one of the practical reasons our NETCC accreditation matters. Second, that the system being financed is sized to your usage rather than to the loan ceiling; a $15,000 limit is not a target. Third, that the quote shows the loan figures alongside the rebates so you can see exactly what you are financing and why.

Program terms can change, and the figures on your written quote are the ones that apply. If you are weighing timing, the same logic as the rebates holds: a scheme that exists today is worth acting on while it does, but never under pressure - the arithmetic either works for your home or it does not.

Next step

Run the design tool with a recent bill to see what your system looks like, then request the quote. Eligibility is confirmed as part of preparing it, and the loan option is shown on the quote itself if you qualify. Or request a call and we will walk through it.
