Who the $4,099 price is for

$4,099 is what eligible households pay after the Solar Victoria solar rebate and the federal STC discounts. The rebate has fixed conditions, so we check them with you before we quote.

Solar Victoria checks that

  • You own and live in the home
  • Combined taxable income of all owners is under $150,000 a year
  • The property is valued under $3 million
  • No solar panel system installed at the property in the last 10 years, and no previous rebate under the program

If you don’t tick every box

You can still get a quote. We tell you which rebates apply to your home and what the package costs without the ones that don’t, before anything is booked.

Already have solar? The battery side may still suit you. Tick “Yes” on the form and we’ll work it out.

“This company is one of the best I’ve had in Melbourne. I work in the construction industry myself. They are incredibly attentive and patient with details, which is rare.”

Questions before you fill in the form

Is $4,099 the final price?

It is the price for eligible households after the Solar Victoria rebate and STC discounts. Your written quote confirms the final figure, including anything specific to your home such as a switchboard upgrade.

How do I know if I qualify?

Solar Victoria’s rebate is for owner-occupiers with combined owner taxable income under $150,000 a year, a property valued under $3 million, and no solar panel system installed in the last 10 years. Send the form and we check it with you.

I already have solar panels. Is this for me?

If your system went in within the last 10 years, the solar rebate does not apply, so the $4,099 package price won’t either. A battery on its own may still suit you. Tick “Yes” on the form and we’ll quote what fits.

What happens after I send the form?

We contact you, usually the same weekday, to check eligibility and your home. Then you get a written quote. There is no obligation to go ahead.
