Understanding the benefits: How solar saves you money
The primary benefit of solar panels is a significant reduction in electricity bills. Solar panels generate clean electricity during daylight hours, offsetting the need to purchase power from the grid. The amount of savings depends on several factors:
Factors affecting your solar ROI
The ROI for solar panels in Australia hinges on several key factors:
- Energy consumption: Homes with higher electricity usage will see greater savings from solar power generation. Analyse your past bills to understand your consumption patterns.
- System size: The size of your solar system (measured in kilowatts—kW) directly impacts your electricity generation and cost. A larger system produces more power but has a higher upfront cost.
- Electricity prices: Locations with higher grid electricity prices offer a faster payback period for solar due to the increased savings on your bills.
- Sun exposure: Sunshine hours in your area significantly affect solar power generation. Check your region’s solar irradiation data to estimate potential output.
- System efficiency: Choose high-efficiency solar panels to maximise electricity production from sunlight.
- Installation costs: Compare solar quotes from reputable installers to ensure a competitive price for quality equipment and installation.
- Feed-in tariffs: These are payments you receive from your electricity retailer for excess solar energy you export back to the grid. Rates vary by retailer and location.
- Government incentives: Federal and state government incentives can significantly reduce the upfront cost of solar panels, accelerating your solar ROI.
The Australian government offers several incentives to encourage solar panel adoption:
- Small-scale Renewable Energy Scheme (SRES): This scheme provides certificates for each kWh of electricity your solar system generates. You can sell these certificates to electricity retailers, reducing your payback period.
- Solar credits scheme: Some state governments offer additional financial incentives in the form of rebates or upfront discounts on the cost of solar panel systems.
- Instant asset write-off: The cost of your solar system can be instantly subtracted from your taxable income in the year of installation for small firms with annual revenue under $50 million (conditions apply).
- State-based rebates: Many states offer additional rebates on top of the federal incentives, making solar even more affordable.

Calculating your potential savings
The primary benefit of solar panels is the reduction in your electricity bill. Here’s a simplified breakdown of how to estimate your potential savings:
- Analyse your bills: Look at your past year’s electricity bills and calculate your average quarterly or annual consumption (in kWh).
- Estimate solar generation: Use online solar calculators or consult with installers to estimate the kWh your system would generate based on your location and system size.
- Compare costs: Multiply your estimated solar generation by your current grid electricity price to determine the potential annual savings from solar power production.
Example:
- Average quarterly consumption: 2,000 kWh
- Estimated annual solar generation (6.6 kW system): 8,000 kWh
- Grid electricity price: $0.30 per kWh
(Estimated annual solar generation) x (Grid electricity price) = Potential annual savings (8,000 kWh) x ($0.30/kWh) = $2,400
This is a simplified example, and your actual savings may vary depending on factors like feed-in tariffs and your electricity usage patterns.
Demystifying the payback period
The payback period refers to the estimated time for the financial benefits of solar panels (electricity savings and incentives) to offset the initial investment cost. It’s a crucial metric to consider when evaluating your solar ROI. Here’s how payback periods are generally influenced by the factors mentioned earlier:
- Higher upfront costs: Larger systems or premium brands might have a longer payback period despite potentially greater long-term savings.
- Greater potential savings: Higher electricity consumption, higher grid electricity prices, and maximised solar generation can lead to a shorter payback period.
Example:
- The upfront cost of the solar system: $8,000
- Potential annual savings (including SRES certificates): $3,000
Estimated payback period = Upfront cost / Annual savings = $8,000 / $3,000/year = 2.67 years
This example suggests a payback period of approximately 2.67 years. Remember, this is an estimate, and your payback period may vary.
