$7,500 to $9,500off a 30kW system. Your installer claims it, so there is nothing to apply for.
2 to 5 yearstypical payback, driven by the power you use on site rather than what you export.
Demand chargesthe line that appears when your distributor moves you onto a demand tariff. Solar lops the peak it bills on.
The rebate comes straight off the price
If you have been searching for a business solar grant, this is it. Your installer claims the certificates and the value comes off your quote, so there is no form to fill in and nothing to wait for.
The ceiling rises to 1MW
From 1 October 2026 the federal scheme covers systems ten times larger than today, at roughly 20% off the installed price.
Were you quoted 99kW?
Plenty of businesses were capped just under 100kW to stay on the right side of the old cliff. If that was you, the quote is worth revisiting.
It shrinks every January
The deeming period drops a year each January. On a 30kW system, waiting twelve months costs roughly $1,500 to $2,000.
We got ripped off on solar. So we learned everything, so you don't have to.
We set out to power our own home with the sun. We did our homework, we trusted the installer who seemed different from the rest, and we paid close to $100,000. We were charged for German batteries and handed cheap knock-offs. The system couldn't get through a normal week, and we spent five years putting it right.
Then we realised our story wasn't rare. Around one in three Australian solar systems is now an orphan, abandoned by the company that installed it. So we built Why Solar to make sure what happened to us stops with us. We don't sell solar. We vet the installers, and we tell you the truth, even when it earns us nothing.
What people say
Real reviews from Australians who used Why Solar to find their installer.
“Spent a few weeks going through this site before installing. Now charging the car off the sun most days. Setup's paying for itself faster than I expected.”

“Finally, solar advice I can actually trust. No pressure, no pushy sales stuff, just straight up honest info.”
Jasmine, Marlborough
“They're completely independent, so I felt like I was getting advice that was actually in my best interest.”
Alice, Marlborough
“Really great business to deal with, they saved me so much time and hassle. Would recommend!”

Every installer clears all six checks
A warranty is only as good as the company behind it, and a commercial system has to still be running long after the payback period. Before we put our name to an installer, they have to pass every one of these. Most don't make the list.
Credentials
Accreditation and licensing, current and genuine, checked rather than assumed.
Staying power
Years actually trading, and the financial stability to still be here in a decade to honour what they promise.
Proof of work
Real installations we can examine, not a folder of stock photos and slogans.
The actual hands
Who physically turns up to do the job, not the cheapest available subcontractor.
What goes in
Genuine, traceable components that match the quote exactly. No quoting German and fitting Chinese.
How they handle trouble
How they behave when something goes wrong. That, not the sales call, is the true measure of a company.
