Solar Price Explorer
Check whether a solar quote looks low, fair, or high, then see what inclusions and red flags to review before you sign.
6.6kW national guide range
Useful starting point before entering a quote. Value-to-standard installer prices usually already include federal solar STCs.
10kW national guide range
Useful starting point before entering a quote. Value-to-standard installer prices usually already include federal solar STCs.
Check your quote
Use the price including GST after the advertised STC discount, unless your quote clearly separates it. Ask installers to itemise STCs and any state support.
Simple access, limited shading, and straightforward switchboard work.
Solar-only quote.

Enter a quote to check it
The guide below shows a reasonable market range before you enter a quote.
Value-to-standard range, usually after federal solar STCs. Estimated STC value for this system: about $1,710. Premium or complex installs can sit above this.
Quality tiers for your inputs
National average, standard single-storey roof
Sharp value
Low-price market or promotional quote. Check component models, workmanship warranty, and exclusions carefully.
Standard
Common value-to-mid quote range for straightforward installs using known equipment and local support.
Premium
Higher-quality panels, inverter options, monitoring, aesthetics, shade handling, or more complex design.
Quote inclusions to look for
- Panel brand, model, product warranty, and performance warranty
- Inverter brand, model, warranty length, and monitoring details
- Mounting system, roof penetrations, and weather sealing approach
- Switchboard, meter, and network connection assumptions
- Expected annual production and self-consumption assumptions
- Workmanship warranty and after-sales support process
Red flags
- The quote is far below market without explaining component or install trade-offs
- The salesperson promises a fixed payback without checking your bill and usage pattern
- Panel or inverter model numbers are missing
- Warranty support depends on overseas-only contacts
- Pressure to sign today or lose a rebate that is not clearly sourced
Battery add-on guide
A battery can make sense for evening use or backup, but it should be checked separately from solar panel payback.
Small battery add-on, around 5 kWh
Usually suited to light evening usage or backup of selected circuits. Battery rebates may reduce this if eligible.
Medium battery add-on, around 10 kWh
Common size for households trying to shift more solar into the evening. Treat support as a separate item.
Large battery add-on, 13 kWh plus
Needs careful payback checking unless backup or resilience is a major goal.
Rebate checks before comparing quotes
Use these as itemisation prompts, not guaranteed savings.
Federal solar STCs
Usually already deducted from installer quote prices. Ask for the STC count and dollar value.
Battery support
Federal battery support and some state offers may apply only if battery eligibility rules are met.
Loans and VPPs
Loans and VPP incentives can help cash flow, but they are not the same as guaranteed rebates.
Need a like-for-like comparison?
Ask each installer for the same system size, battery assumption, panel tier, inverter type, and production estimate. That makes price differences much easier to judge.
