Solar power systems have grown more affordable in Perth, making the option increasingly attractive for both residential and commercial properties. For Brisbane-based company Isolux Solar, understanding the costs in Perth can help you address customer questions and highlight any differences between cities. Here’s an in-depth look at the costs involved in Perth.
Average Cost of Solar Systems in Perth
Solar system prices in Perth vary depending on system size, quality, and installation specifics. Currently, you can expect approximate costs after government rebates as follows:
- 3 kW system: around $3,000 to $4,000
- 6.6 kW system: about $4,500 to $6,000
- 10 kW system: between $8,000 and $10,000
Prices are typically lower than the Australian average due to high competition among installers in Perth, and ongoing incentives like Small-scale Technology Certificates (STCs) provide substantial savings.

Factors Influencing Solar Panel Costs
Several factors influence solar system costs, including:
- Panel Quality and Brand: Premium brands (e.g., LG, SunPower) tend to cost more but offer higher efficiency and durability. Budget options can still deliver good performance with slightly lower longevity.
- System Size and Energy Needs: Larger systems, like 6.6 kW or 10 kW, are more cost-effective long-term, especially if energy consumption is high.
- Government Rebates and STCs: In Perth, STCs cover approximately 30% of installation costs, depending on the system size and the current market rate per STC, which can fluctuate from $34 to $40.
Feed-in Tariffs in Perth
Western Australia offers a feed-in tariff for surplus energy sent back to the grid, but the rates are generally low. As of recent rates:
- 2.75 cents per kWh for standard times
- 10 cents per kWh between 3 pm and 9 pm
This structure encourages homeowners to maximize their “self-consumption” of solar energy during the day. The low feed-in rate emphasizes the importance of using generated power on-site, which reduces reliance on the grid and minimizes energy bills.
Estimated Savings from Solar Panels
A typical Perth household with a 6.6 kW solar system can expect savings ranging from $1,200 to $2,000 per year on energy bills. For a larger 8 kW system, savings can exceed $3,000 annually, making solar a high-return investment over time.
Payback Period and Long-term Value
The payback period for Solar Panels in Perth is generally between 3 to 5 years, depending on energy usage patterns and initial installation costs. Systems with higher self-consumption rates (i.e., energy used directly by the household) will see quicker returns due to lower reliance on the grid. Solar installations also increase property value, an appealing aspect for both homeowners and renters.
Are Solar Batteries Worth It in Perth?
While battery storage options like the Tesla Powerwall offer energy independence, they remain costly, often between $10,000 and $14,000. Due to a lengthy payback period, many homeowners may find it financially wise to wait until battery costs decrease further.
Conclusion
Perth’s solar market offers competitive pricing, supported by abundant sunshine, making it one of the best locations in Australia for solar energy investment. Lower installation costs, government incentives, and strong annual energy savings make Perth’s solar market vibrant and financially attractive.
