In Perth, a typical 6.6kW solar panel system installation costs approximately $4,500 to $7,000 after government rebates, with prices varying based on the quality of panels, inverters, and specific installation needs. Factors such as system size, brand selection (premium options include Seraphim, Longi, Jinko, and ET Solar panels), inverter choice (Growatt, Fronius, or Huawei), and potential installation complexity, like roof upgrades, will influence the final price.

You’ve likely heard about the many benefits of solar panel installation, yet if you haven’t made the switch to solar, it’s probably due to one main concern: the cost of solar panel installation in Perth.
While solar panel costs in Perth have decreased significantly over recent years, for the average Australian household, it still represents a substantial investment. The Vista Electrical Controls team is here to provide a comprehensive breakdown of solar panel installation costs in Perth for 2025, giving you a clear understanding of exactly what your solar power system will cost.
Looking for a straightforward answer? Here’s everything you need to know.
The cost of solar installation depends on several key factors, including your location, the size of system you choose, your property characteristics, and your energy goals. Generally, you can expect solar panel installation costs to range between $3,000 and $12,000 after rebates.
Solar installation costs vary considerably based on these factors. This guide will help you make an informed decision when planning your solar system investment.
Key Factors Affecting Solar Panel Installation Costs
Understanding what influences your solar installation cost is crucial for making the right investment decision:
- Location and regional factors
- System size and energy requirements
- Grid-connected vs off-grid system choice
- Available solar rebates and incentives
- Property orientation and characteristics
- Quality of installer and equipment
1. Location Impact on Solar Costs
Your location plays a pivotal role in determining solar panel installation costs. Each Australian state offers different solar rebate structures and incentives, which directly affects your final investment.
Different states and territories provide varying solar rebate amounts for each kilowatt of energy capacity installed, making location a critical cost factor.
2. Solar System Size Selection
The size of your chosen solar system significantly impacts installation costs. System sizing depends on your household’s energy consumption patterns and the amount of available roof space.
Perth’s exceptional solar conditions mean your photovoltaic panels will generate more electricity compared to households in less sunny locations like Sydney, making larger systems particularly cost-effective here. Read our Perth homeowner’s guide to solar power for more insights on maximising your solar investment.
3. Grid-Connected vs Off-Grid Solar Systems
Your choice between grid-connected and off-grid systems substantially affects installation costs.
Grid-Connected Solar Systems represent the most cost-effective option for most Perth properties. These systems include solar panels and inverters connected to your main electricity grid, allowing you to use grid power when your panels aren’t generating sufficient electricity (such as at night). During the day, your home operates on clean solar energy, with any excess power feeding back into the grid. Learn more about our residential solar systems.
Off-Grid Solar Systems operate independently from the main electricity grid, making your property completely energy self-sufficient. These systems require solar batteries to store excess energy for use during evening hours or cloudy periods. While offering complete energy independence, off-grid systems require higher upfront investment and careful planning. They’re ideal for remote locations where grid connection isn’t available.
4. Solar Rebates and Government Incentives
Solar rebates play a crucial role in reducing your overall installation costs. The Australian government provides several incentive programs to encourage renewable energy adoption.
Three Primary Solar Rebate Types:
- Federal government rebates
- State government rebates
- Feed-in tariffs
These rebates vary by location and directly impact your solar installation investment.
Understanding Solar Rebate Programs
Australian Federal Rebates: The federal government provides rebates for both small-scale and large-scale solar installations through the Small-scale Renewable Energy Scheme. This program encourages Australian households and businesses to adopt solar energy, with benefits available through 2030.
State Government Rebates: Individual state governments offer additional incentives to encourage solar adoption among residential and commercial property owners. Some states subsidise solar installations, while others provide support for solar battery installations.
Feed-in Tariffs: Your electricity provider pays you for excess energy your solar system feeds back into the grid. Rather than wasting surplus solar energy, you receive payment for each kilowatt-hour of excess power generated. Discover more about how solar energy works and maximising your system’s efficiency.
Feed-in tariff rates vary by state, electricity provider, and your specific electricity plan. Research available feed-in tariff options when calculating your solar installation costs.
Important: Always choose a Solar Accreditation Australia (SAA) certified installer like Vista Electrical Controls to ensure eligibility for all available rebates and incentives. Read our guide on questions to ask before choosing a Perth solar installer to make the right choice.
5. Property Orientation and Site Characteristics
Your property’s orientation significantly impacts both solar system performance and installation costs.
Roof Direction: North-facing roofs provide optimal solar panel performance, receiving maximum direct sunlight throughout the day. East and west-facing roofs can also work effectively, though they may generate slightly less energy.
Shading Considerations: Trees, neighbouring buildings, or other structures casting shadows on your roof reduce solar panel efficiency. Properties with minimal shading achieve better performance, while shaded properties may require additional planning or alternative installation approaches.
Roof Condition: Your roof’s structural condition affects installation complexity and costs. Roofs requiring repairs or upgrades before installation will increase overall project costs. Learn about preparing your home for solar installation to ensure a smooth process.
