What Is the Average Cost of Solar Panels in Australia?
The average cost of a solar panel installation in Australia varies significantly because homeowners purchase complete solar power systems rather than individual panels alone. A complete system typically includes solar panels, an inverter, mounting hardware, electrical protection, installation labour and commissioning.
For a practical price comparison, ADS Solar currently advertises a 6.6kW solar system from $3,999* and a 10kW solar system from $5,999*. Larger systems may offer a lower installation cost per watt where roof space and electrical infrastructure allow.
These figures are ADS Solar starting prices rather than an independently calculated Australian market average. For an accurate installed price, request an itemised quote based on your property.

What Affects Solar Panel Installation Costs in Australia?
Two solar systems with the same advertised capacity can have different installed prices. Understanding the main cost drivers helps you assess quotes fairly.
1. Solar Panel Capacity and Efficiency
Higher-capacity systems usually require more panels, mounting components and electrical work. Premium high-efficiency panels may cost more but can be useful when roof space is limited.
2. Solar Inverter Selection
The inverter converts solar electricity into usable AC electricity. Inverter cost depends on brand, capacity, phase configuration, monitoring capability and compatibility with future batteries.
3. Roof Type and Accessibility
Metal and tiled roofs can require different mounting systems and installation techniques. Steep roofs, difficult access and additional safety equipment may increase labour costs.
4. Switchboard and Electrical Upgrades
Some properties need switchboard modifications, metering changes, additional protection devices or electrical infrastructure upgrades before solar installation can proceed.
5. Location and Network Approval
Installation costs and network connection requirements vary between Australian states, distributors and individual properties. Export limits may also influence the recommended system design.
6. Warranties and Installation Quality
Compare equipment warranties, workmanship coverage, installer accreditation, monitoring access and after-sales support alongside the upfront price.
What Should Be Included in a Solar Installation Quote?
- Solar panel brand, model, quantity and total capacity.
- Inverter brand, model and rated output.
- Mounting equipment, electrical protection and cabling.
- Installation, testing and commissioning.
- Grid connection and metering responsibilities.
- Estimated solar generation and financial assumptions.
- Applicable STC discount and any other incentives.
- Equipment warranties and workmanship warranty.
- Any exclusions or possible additional charges.
Solar Panel Rebates and Government Incentives in Australia in 2026
Government incentives can reduce the upfront cost of an eligible solar installation. However, the value depends on the installation date, system capacity, location and applicable scheme rules.
Federal Small-Scale Technology Certificates (STCs)
Australia’s Small-scale Renewable Energy Scheme supports eligible solar installations through Small-scale Technology Certificates, commonly called STCs. These certificates have a market value and are frequently assigned to the solar retailer in exchange for an upfront discount on the customer’s invoice.
The number of STCs depends on the system’s eligible capacity, installation location, applicable deeming period and scheme requirements. The federal scheme is scheduled to progressively reduce support through to 2030.
State and Territory Solar Incentives
Additional assistance may be available in certain states or territories, including targeted household programs, loans or battery-related incentives. These programs can open, close or change eligibility.
Before purchasing, review the latest information from the relevant government authority and check whether the incentive can be combined with the federal STC scheme.

How Much Money Can Solar Panels Save in Australia?
Solar savings depend on how much electricity your system produces, how much of that electricity you use directly, your retail electricity tariff and the feed-in tariff for surplus exports.
Electricity consumed directly from your solar system usually has greater financial value than electricity exported to the grid, particularly when the feed-in tariff is lower than the price you pay for imported energy.
Illustrative Annual Solar Savings Calculation
Consider a household with a solar system generating 9,000kWh annually. Assume 40% of production is used directly in the home and the remaining 60% is exported.
| Calculation | Example |
|---|---|
| Annual solar generation | 9,000kWh |
| Direct household consumption | 3,600kWh |
| Grid exports | 5,400kWh |
| Assumed avoided electricity cost | $0.30/kWh |
| Assumed feed-in tariff | $0.05/kWh |
| Direct consumption savings | $1,080/year |
| Export credits | $270/year |
| Total estimated annual benefit | $1,350/year |
This is an illustrative calculation, not a forecast or savings guarantee. It excludes changes in tariffs, fixed daily supply charges, maintenance costs, degradation and other property-specific factors.
How Long Does It Take for Solar Panels to Pay for Themselves?
Simple solar payback is calculated by dividing the net upfront system cost by estimated annual financial benefits.
A realistic assessment should consider your actual electricity bills, roof suitability, consumption profile and local electricity tariffs.
Solar Panel Installation Costs Across Australia
Solar panel prices can vary between Sydney, Melbourne, Brisbane, Adelaide and Canberra due to differences in labour, logistics, roof conditions, network rules and the incentives available at the installation address.

How Much Do Solar Panels Cost With Battery Storage?
Adding battery storage increases the upfront investment but can help households use more of their solar generation during the evening or at other times when solar panels are not producing electricity.
Battery pricing depends on usable storage capacity, inverter compatibility, backup capability, installation requirements and applicable incentives.
Solar and Battery Installation Considerations
- Choose battery capacity based on your evening and overnight electricity usage.
- Confirm whether the battery can work with your existing or proposed inverter.
- Ask whether backup power is included or requires additional hardware.
- Check usable capacity, warranty terms and expected operating conditions.
- Confirm the eligibility and value of any battery incentives.

How to Choose the Right Solar System for Your Home
The cheapest solar system is not necessarily the most economical option over its operating life. The right system should balance upfront cost, expected production, equipment reliability and your actual energy needs.
- Review your electricity bills. Check annual consumption in kilowatt-hours, not just the dollar value of the bill.
- Understand when you use electricity. Homes with high daytime usage may achieve greater direct solar self-consumption.
- Assess your roof. Consider available area, orientation, shading, roof condition and future renovations.
- Plan for future demand. Electric vehicles, heat pumps, electric cooking and home batteries may influence system sizing.
- Compare equipment and warranties. Look beyond headline price to panel specifications, inverter quality and after-sales support.
- Request a detailed installation quote. Confirm the complete installed price, assumptions, exclusions and grid connection requirements.
