What price should I be paying for a solar system?

As of August 2024, approximate prices for good quality solar panel systems in Australia (Tier 1 panels + quality central inverter), fully installed, are:

6.6 kW: $5,500 – $9,000
10 kW: $8,000 – $13,000
13.3kW: $10,000 – $15,000

To be clear - the upper end prices are for top-end systems (e.g. REC panels with full panel level optimisation), installed by a solar 'craftsman'.

Note that the above prices also include the discount from the solar 'rebate'.

Costs can increase if you need a switchboard upgrade or other electrical work to make your home suitable for solar panels, or if the design of your home makes the install more difficult. If you decide to go with micro inverters over a central inverter, costs will also increase by approx 20-30%.

Adding battery storage (for an off-grid or hybrid system) will also increase costs.

If you're quoted much less than these price ranges by a solar salesman, chances are they're cutting corners somewhere or using inferior quality products to deliver a lower overall cost. So, be wary!
