The question on many Australian homeowners’ minds in 2026 is whether rooftop solar panels still deliver value, particularly with the widespread reduction, and in some cases elimination, of solar feed-in tariffs (FiTs). The direct answer is a resounding yes, solar panels are still a highly worthwhile investment in Australia in 2026, even without a home battery and in the face of zero feed-in tariffs. The economics have shifted from exporting excess power to the grid towards maximising your own solar self-consumption.
Historically, generous feed-in tariffs made exporting solar power a significant revenue stream. However, the landscape has changed. From 1 July 2026, major retailers like AGL have confirmed that customers on their Standard Retail Contract will receive a 0 c/kWh feed-in tariff. Other retailers like EnergyAustralia are reducing their standard rates to 3 c/kWh, and Momentum Energy offers as low as 0.8 c/kWh in South Australia. Victoria, too, removed its minimum feed-in tariff from 1 July 2025, allowing retailers to set their own rates. This means the financial benefit now comes primarily from avoiding the high cost of buying electricity from the grid.
The Power of Self-Consumption: Avoiding High Retail Prices
In 2026, the average retail electricity price across Australia sits around 31 cents per kilowatt-hour (c/kWh). In states like South Australia, competitive market offers can reach 34-40 c/kWh. Every kilowatt-hour your solar panels generate and you consume directly means you avoid paying these high retail rates. This is where the significant savings lie.
“A household in South Australia paying 38 c/kWh gets far more value from every kWh of self-consumed solar than a household in Victoria paying 28 c/kWh — even if their systems are identical.”
By using your solar power during the day, you effectively ‘buy’ electricity from your roof for a fraction of the grid price. Over the lifetime of a system, our analysis shows that rooftop solar panels can produce electricity at close to 4c per kilowatt-hour. This substantial difference creates a strong financial incentive for solar ownership.
Current Solar System Costs & Rebates in 2026
The upfront cost of a solar system remains a key consideration, but federal and some state-based incentives continue to make it accessible.
Federal Small-scale Technology Certificates (STCs): The primary federal incentive is the Small-scale Renewable Energy Scheme (SRES), which provides Small-scale Technology Certificates (STCs). These certificates are typically claimed by your installer and applied as an upfront discount on your system price. In 2026, the STC value for a typical 6.6kW system is worth roughly $2,000–$3,000. The STC value decreases annually until the scheme ends in 2030, so installing sooner generally captures a higher rebate. The STC market price has been around $36-$40 per certificate in early 2026.
Typical Installed Solar System Costs (After Federal STC Rebate, 2026):
| System Size | Average Cost Range (AUD) | Best For |
|---|---|---|
| 6.6 kW | $5,000 – $9,000 | Most popular, 3-4 people, single-phase homes |
| 10 kW | $8,000 – $13,000 | Larger homes, high usage, EV charging, three-phase homes |
Note: Prices vary based on panel and inverter quality, roof complexity, and location. Premium systems can add 20-30% to these figures.
State-Specific Solar PV Rebates (without battery, 2026):
- Victoria: The Solar Homes Program offers eligible households a rebate of up to $1,400 for solar PV systems, along with an optional interest-free loan for an equivalent amount. From 1 July 2026, the combined household income cap for this rebate changes from $210,000 to $150,000 per year.
- New South Wales: While there isn’t a broad upfront state rebate for standard rooftop solar PV, the NSW Home Energy Saver program, launched in June 2026, offers interest-free loans of up to $15,000 over 10 years for energy upgrades, including solar panels and batteries, for households with a combined income under $210,000. Targeted discounts of up to $4,000 will also be available later in 2026 for lower-income households.
- Other States: Primarily rely on the federal STC scheme for solar PV incentives.
Payback Periods and Return on Investment
With current electricity prices and available rebates, a typical 6.6kW residential solar system in Australia can achieve a payback period of 3 to 6 years. After this, your system generates essentially free electricity for the remainder of its 25+ year lifespan. This represents a significant long-term return on investment, especially when compared to other household investments.

Maximising Your Savings Without a Battery
To get the most out of a solar-only system in a low or zero FiT environment, focus on shifting your electricity consumption to daytime hours when your panels are generating power. This includes:
- Timing Appliances: Run dishwashers, washing machines, and pool pumps during the middle of the day.
- Smart Home Devices: Utilise smart plugs and timers to automate appliance usage during peak solar production.
- Electric Hot Water: If you have an electric hot water system, consider a timer to heat water during the day.
- EV Charging: If you own an electric vehicle, charge it during the day when solar power is abundant. Our guide on Best Home EV Chargers in Australia 2026: Costs from $1,400 & Smart Features Explained provides options for optimising this.
Future-Proofing for Battery Storage
While this guide focuses on solar without a battery, it’s prudent to consider future battery integration. Most modern inverters are ‘battery-ready’, meaning you can easily add a battery later when your budget allows or if battery economics become even more compelling. The federal Cheaper Home Batteries Program also provides significant incentives for battery installations, offering around $252 per usable kWh from May to December 2026.

Choosing the Right System and Installer
Investing in quality components is crucial for long-term performance and savings. Popular and efficient solar panel brands in Australia for 2026 include SunPower (Maxeon 6), REC (Alpha Pure-RX), Jinko (Tiger Neo N-type), LONGi (Hi-MO X6), and Trina (Vertex S+). For inverters, reputable brands like Fronius, Sungrow, and SMA are widely used. Always ensure your installer is Clean Energy Council (CEC) accredited.
Bottom Line
Despite low or zero feed-in tariffs, installing solar panels in Australia in 2026 remains an excellent financial decision. The substantial savings come from avoiding high retail electricity prices by consuming your own generated power. With average retail rates around 31 c/kWh and solar electricity costing as little as 4 c/kWh to produce, the return on investment is clear. Factor in federal STC rebates and potential state incentives (like Victoria’s $1,400 rebate or NSW’s interest-free loans), and typical payback periods of 3-6 years make solar a compelling investment for reducing your energy bills and increasing your energy independence for decades to come. Focus on smart daytime energy usage, choose quality components, and consider a battery-ready inverter for future flexibility.
