How Does Zero Upfront Solar Actually Work?

The Green Energy Deal was brought in to help people switch to solar for zero upfront cost. No deposit, no big cheque, nothing to find before you start saving.

Here's the simple version of how it works.

Right now, you're paying dead money

Every month, that payment to Ergon goes out the door. And once it's gone, it's gone. It doesn't build you anything. It doesn't come back. It just keeps the lights on for another month, and then you start again from zero.

What if that same money bought you something instead?

With the Green Energy Deal, you put roughly the same money toward paying off your own solar and battery system instead. Same money leaving your account each month, but now it's going toward an asset. One that adds value to your home and cuts your power costs at the same time.

And more often than not, the repayments come in cheaper than what you're already paying Ergon.

Once it's paid off, you just keep the savings

After a few years, the system's paid off and it's yours. No more repayments, no more power bills to speak of. You just get to enjoy cheap power from here on. Simple as that.

What it actually looks like

• Right now: your Ergon bill averages around $280/month. That money is gone the moment you pay it.

• With solar + battery: your actual power bill drops to close to $0/month.

• With the Green Energy Deal: your system repayment comes in around $250/month.

That means switching doesn't cost you extra. It saves you $30 a month from day one, and instead of renting power from Ergon forever, you're paying off something that's actually yours.

Then, once the system's paid off, that $250/month disappears too. You just keep the near-$0 power bill. Permanently.

You're not just $30 better off. You're building an asset, not a liability

This is the part most people miss. It's not just about the monthly saving.

When you pay Ergon, that money is gone the second it leaves your account. You'll never see it again. It doesn't build you anything and it doesn't come back.

When you pay the repayment on your system, you're paying for an asset. A 2025 Cotality report, produced in partnership with the Commonwealth Bank and analysing over six million Australian homes, found that properties with solar systems carry a measurable price premium at sale. Nationally, that premium averaged around 2.7%, or roughly $23,100 per home, with regional areas like the Northern Territory seeing uplifts as high as 6.9% (Cotality, 2025). So the system isn't just cutting your bills while you live in the home. It's adding real value to it.

And once it's paid off, it's yours outright. No more repayments, no more rising Ergon prices to worry about, and a system that's already added value to your property.

It's really the same logic as paying a mortgage instead of renting for life. Rent is money gone forever. A mortgage repayment builds equity in something you'll eventually own outright. The Green Energy Deal works the same way, just with your power system instead of your house.

The bottom line

You're going to spend money on power either way. The only question is whether that money disappears every month, or whether it eventually buys you a paid-off system and close to free power for the life of your home.

We've helped hundreds of homeowners across Toowoomba, the Darling Downs, and greater Queensland make this exact switch with zero upfront cost. Want to see what solar/batteries could do for your property?
