The 6.6kW system remains the most popular choice among Canberra households, offering an optimal balance between cost, energy production, and available roof space. This system typically generates enough electricity to power a standard 3-4 bedroom home. Actual prices vary based on equipment quality and installer, with premium systems at the higher end of ranges.
Factors Affecting Installation Costs
Several variables influence the final price of your solar installation:
Equipment Quality: Premium brands like LG, SunPower, or Q Cells command higher prices but offer superior efficiency and longer warranties. Budget-friendly options from Trina Solar or Canadian Solar provide reliable performance at lower costs.
Inverter Selection: String inverters are the most economical option, while microinverters or power optimizers increase system costs by 15-25% but offer better performance in shaded conditions.
Roof Complexity: Multi-story homes, tile roofs, or installations requiring structural upgrades increase labor costs. Simple single-story metal roof installations are typically the most affordable.
Installation Location: Labor rates and travel costs vary across Canberra’s suburbs, with regional areas like Jerrabomberra or Queanbeyan potentially incurring higher charges.
Federal Solar Rebates: Small-scale Technology Certificates (STCs)
The Australian government’s STC scheme provides the foundation for solar affordability in Canberra. This incentive reduces upfront installation costs by approximately 30-40% for most residential systems.
How STCs Work
STCs are renewable energy certificates created when you install an eligible solar system. Each certificate represents one megawatt-hour of renewable electricity your system will generate over its “deeming period” (the years remaining until December 2030).
The STC calculation formula for Canberra (Zone 3):
Number of STCs = System size (kW) × Zone rating (1.382) × Deeming period (years until 2030)
For example, a 6.6kW system installed in early 2026:
- 6.6kW × 1.382 × 4.5 years (mid-2026 installation) = 41 STCs
- 41 STCs × $38 (average 2026 trading value) = $1,558 rebate
- At higher market rates: 41 STCs × $40 = $1,640 rebate
Note: Installing in early 2026 maximizes your rebate. The deeming period reduces to 4 years by late 2026, and 3 years in 2027, significantly decreasing STC values. For larger systems (10kW+), STCs can range from 55-75 certificates, yielding rebates of $2,900-$3,500.
Important STC Considerations
Time-Sensitive Rebates: The deeming period decreases by one year annually, reducing available STCs. Installing in 2026 versus 2027 could mean a difference of several hundred dollars.
Automatic Application: Most installers handle STC creation and assignment, immediately deducting the value from your quote. You never directly receive or manage certificates.
Eligibility Requirements: Your system must be installed by a Clean Energy Council (CEC) accredited installer using CEC-approved panels and inverters. Systems must not exceed 100kW capacity for residential properties.
ACT Government Solar Rebate Programs
Beyond federal incentives, the ACT government offers targeted rebate programs to specific homeowner groups, making solar even more affordable for eligible residents.

Solar Feed-in Tariffs in Canberra
Feed-in tariffs (FiTs) provide ongoing income by crediting your electricity bill for excess solar energy exported to the grid. Unlike other Australian states, the ACT does not mandate minimum FiT rates, creating a competitive voluntary market.
Current FiT Rates (2026)
Important: Feed-in tariff rates are voluntary in the ACT and change frequently. Always verify current rates with retailers before signing up.
| Energy Retailer | Feed-in Tariff Rate | Additional Notes |
|---|---|---|
| Origin Energy | 10-12c/kWh | Subject to plan selection |
| ENGIE | Up to 12c/kWh | Premium plans only |
| Red Energy | 8-10c/kWh | Competitive overall rates |
| ActewAGL | 8c/kWh | Local provider, standard rate |
| AGL | 4-8c/kWh | Varies by plan tier |
Note: Legacy premium FiT schemes (30-45c/kWh) from pre-2011 installations are closed to new applicants. Daytime export rates tend to be lower as grid saturation increases.
Maximizing FiT Returns
Compare Total Bill Costs: A higher FiT may be offset by higher usage charges or daily supply fees. Evaluate the complete plan structure.
Legacy FiT Holders: Customers who installed solar before July 13, 2011, may still receive premium rates (30-45c/kWh) for up to 20 years. Upgrading your system terminates this arrangement unless you install a completely separate system.
Time-of-Use Optimization: Some retailers offer time-varying FiTs with higher rates during peak demand periods. Smart energy management systems can maximize export during these windows.
Self-Consumption Priority: With FiT rates ranging from 8-12c/kWh but grid electricity costing 25-35c/kWh, using solar power directly saves significantly more than exporting.
Solar System Energy Production in Canberra
Canberra’s climate offers excellent solar potential, with the city receiving an average of 4.5-5.0 kilowatt-hours (kWh) per installed kilowatt of solar capacity daily.

Return on Investment and Payback Period
Understanding your solar investment timeline helps evaluate financial viability and long-term savings.
Payback Period Calculation Example
For a typical 6.6kW system with realistic 2026 pricing:
System Cost: $6,000 (average net cost after STC rebate)
Annual Savings Breakdown:
- Self-consumed solar (70% of production): 7,665 kWh × 30c/kWh = $2,300
- Feed-in tariff (30% exported): 3,285 kWh × 10c/kWh = $329
- Total annual savings: $2,629
Simple Payback Period: $6,000 ÷ $2,629 = 2.3 years
Realistic Range: Most Canberra households achieve payback in 3-5 years depending on:
- Self-consumption rate (60-80% optimal)
- Electricity usage rates (25-35c/kWh in 2026)
- Feed-in tariff received (8-12c/kWh)
- System cost variations ($4,800-$7,000 net)
After the payback period, your system continues generating free electricity for 20-25+ years, potentially saving over $50,000-$70,000 in lifetime electricity costs.
Factors Affecting ROI
Electricity Price Inflation: Grid electricity costs typically increase 3-5% annually, accelerating your savings rate over time.
Self-Consumption Rate: Households using 70-80% of generated solar directly achieve payback 12-18 months faster than high-export households.
System Maintenance: Quality panels require minimal maintenance. Budget $200-300 every 2-3 years for professional cleaning and inverter monitoring.
Battery Storage: Adding battery storage (typically $8,000-15,000) extends payback to 7-10 years but provides energy independence and backup power during outages.
