Real Solar Quotes in Perth: Example System Prices (2026)
Ranges are useful, but example numbers are easier to picture. The scenarios here are typical Perth market examples for 2026 - illustrative price pictures built from standard installed pricing, not jobs done by any particular installer - so you can sanity-check the real quotes you collect.
Quick answer — example Perth solar prices (2026)
| Market example | System spec | Indicative installed price |
|---|---|---|
| 6.6 kW, single-storey, northern suburbs | 6.6 kW panels, 5 kW inverter, single-phase | $5,500 – $7,500 |
| 10 kW + 13.5 kWh battery, two-storey | 10 kW panels, hybrid inverter, 13.5 kWh battery | $18,900 – $28,000 |
| 13.2 kW, three-phase family home | 13.2 kW panels, three-phase inverter | $9,500 – $16,000 |
Ranges are useful, but example numbers are easier to picture. The three scenarios below are typical Perth market examples for 2026 — illustrative price pictures built from standard installed pricing across the metro area, not jobs done by any particular installer. Use them to sanity-check the quotes you collect: if a real quote sits well outside the range for a comparable system, that is your cue to ask why, not to assume you have found a bargain or been overcharged. Each example band sits inside the wider cluster ranges — the 6.6 kW example, for instance, is a mid-market point within the full $4,200 to $8,900 that 6.6 kW systems span — so a real quote a little above or below is normal, not a contradiction of the range.
How to read a Perth solar quote
What a complete quote includes
A proper Perth quote should be a fixed installed price that already nets off the federal STC discount and covers the panels and inverter (both named by brand and model), the mounting and racking, the electrical work, a standard single-storey installation, and the Western Power and Synergy connection paperwork. CEC-accredited design and install should be stated, not implied. If the price is a "from" figure or leaves the rebate as a separate line you have to chase, treat it as an estimate rather than a quote.
What is usually excluded — and where quotes diverge
The gap between two quotes for the "same" system is almost always in the things sitting outside the headline. A switchboard upgrade, a meter change, an upgrade from single- to three-phase supply, difficult or two-storey roof access, tile roofs that need careful loading, long cable runs from roof to switchboard, optimisers to manage shading, or a backup gateway for a battery — any of these can add hundreds to a few thousand dollars. A quote that comes in well under the others by quietly assuming none of them applies is not really a better deal; it is incomplete. Ask each installer to spell out what their price assumes about your roof, your phase supply and your switchboard.
Red flags
The warning signs are consistent: a price far below the market range for the spec, high-pressure "today only" discounts, no panel or inverter brand named, no CEC accreditation, an oversized deposit, vague wording on who lodges the Western Power application, "free" battery or upgrade bundles that only make sense if the base price is inflated, and warranties quoted in years without saying who honours them. None of these is automatically a scam, but each is a reason to slow down and get the detail in writing.
Example 2, line by line — 10 kW + 13.5 kWh battery
This is an illustrative breakdown of the second market example — a two-storey Perth home adding storage at the same time as a larger array. It is a typical market composition, not an actual customer's invoice.
| Line item | Indicative cost |
|---|---|
| 10 kW solar system, installed (panels + hybrid inverter) | $6,300 – $12,600 |
| 13.5 kWh battery (Tesla Powerwall 3), installed | $12,600 – $17,850 |
| Panels-plus-battery sum | $18,900 – $30,450 |
| Two-storey access and a backup gateway | within the band above |
| Typical all-up installed (this scenario) | $18,900 – $28,000 |
Both lines above are installed, incentive-inclusive prices — the 10 kW array already nets off the federal STC discount and the battery price is all-in — so there is nothing extra to add or subtract. Add them and the panels-plus-battery system sums to $18,900 to $30,450; a typical two-storey install with a backup gateway lands around $18,900 to $28,000. Strip the battery out and the same 10 kW array sits in the $6,300 to $12,600 band the pillar quotes — the battery is the larger of the two line items, which is why adding storage roughly doubles to triples the all-up price.
Frequently asked questions
What should a Perth solar quote include?
A fixed installed price already net of the STC discount, the panels and inverter named by brand and model, mounting and electrical work, a standard install, and the Western Power and Synergy connection paperwork. CEC-accredited design and install should be stated, not implied.
Why do solar quotes vary so much?
The gap is almost always in the exclusions - a switchboard upgrade, meter change, single-to-three-phase upgrade, two-storey roof access, long cable runs or a battery backup gateway. A lower quote that has assumed none of these applies is incomplete rather than better value.
How many solar quotes should I get in Perth?
Three for a comparable specification - enough to spot an outlier high or low without dragging the process out. Compare the net installed price and the named equipment, not the size of the rebate each company claims to give you.
Is a much lower quote a good sign?
Usually not. A price well below the market range for the spec generally means something has been left out - or the panel and inverter brands are not named. Slow down and get the detail in writing before committing.
