Rebate clarity
Solar rebates and discounts can make two quotes look closer than they really are. A useful Mount Hardey solar quote should separate the federal STC discount, any state program, the equipment price, and the installation scope so you know what you are comparing. Our solar tips guide covers how to read a quote line by line.
Federal STC discount
The STC discount is usually applied upfront by the installer. Ask for it to be shown as a separate line item, because the final discount depends on postcode, system size, STC zone, certificate price, and installation timing.
Western Australia programs
Our current location dataset does not list an additional Western Australia-specific solar panel rebate for Mount Hardey. You can still compare quotes with the federal STC discount shown separately.
Solar + battery quotes
From 1 May 2026, the program uses a 6.8 STC factor for May-Dec 2026. Eligible battery systems are generally 5-100kWh nominal capacity, with certificate support applying to the first 50kWh of usable capacity.
If you are comparing a battery with solar, ask each installer to separate the battery price, usable capacity, backup inclusions, warranty terms, and any battery discount from the solar system price.
Local solar guide
These figures are a guide, not a promise. Your final result depends on your roof, household usage, electricity plan, product mix, installation scope, and the assumptions each installer uses in the quote.

Rebates and discounts
Most residential solar quotes include an upfront federal STC discount — our solar rebates guide explains how it works. Ask installers to show that discount separately from the equipment and installation price, because the final amount depends on system size, postcode, STC zone, certificate price, and install timing.
Solar value
Mount Hardey has an indicative average of 6.2 peak sun hours per day, which is very good for residential solar. A 6.6kW system is modelled to generate around 11,202 kWh a year in this dataset, but the value of that generation depends on how much you use during the day, your tariff, and your export rate.
Instead of relying on one payback number, compare installer assumptions side by side: daytime usage, feed-in tariff, annual bill savings, inverter limits, monitoring, and any battery or EV plans.
System size
The right size depends on your bill history, roof space, phase connection, daytime load, future battery plans, and whether you expect to add an EV or more electric appliances.

Solar + battery
If you are comparing battery storage in Mount Hardey (see our solar battery guide), ask each installer to separate the solar system price, battery price, usable capacity, backup inclusions, warranty terms, and any battery discount details. Since 1 May 2026, the current STC factor is 6.8 forMay-Dec 2026, with support tiered across usable-capacity bands. The cheapest package is not always the clearest one if the quote does not show the battery discount, usable capacity, and backup hardware separately.
