Where Does Your Money Go?

Labour30%

Solar installation labour costs $800–$2,000 for a standard residential system. The installer must hold both an electrical licence and CEC accreditation.

Materials60%

Solar panels, inverter, mounting hardware, and cabling. Panel and inverter quality has the biggest impact on system performance and longevity.

Overhead10%

Includes grid connection application, metering, and compliance documentation. Network connection fees vary by state and retailer.

How to Save on Solar

1

Get quotes in winter when solar installers are less busy and more competitive.

2

Compare the cost per watt ($/W) across quotes — it's the best apples-to-apples comparison.

3

Check if your state has additional rebates on top of the federal STC scheme.

4

Ask about the warranty on panels (25 years), inverter (10 years), and workmanship (5 years).

5

Consider a larger system now — adding panels later costs more than installing them upfront.

Red Flags to Watch Out For

Installer not CEC-accredited (you won't get government rebates)

No product warranty documentation provided

Panels or inverter not from a recognised brand

Significantly cheaper than all other quotes

Pressure to sign immediately to "lock in the rebate"
