Will My Solar System Cost More? Understanding the Rebate Impact
Thinking about going solar? It’s a fantastic way to reduce your electricity bills and your carbon footprint. But one of the biggest questions on everyone's mind is: "How much will it actually cost me?". A significant factor influencing the price of solar systems in Australia is the solar rebate, and recent changes have left many wondering about their impact.
This blog post will break down how solar rebates work, what changes are on the horizon, and what it means for your wallet when investing in solar panels for your home or business.

Understanding the Solar Rebate (STCs)
Currently, the most significant financial incentive for installing solar panels in Australia comes from the Small-scale Renewable Energy Scheme (SRES). This scheme operates using Small-scale Technology Certificates (STCs). When you install an eligible solar system, you're entitled to a certain number of STCs. The number of STCs you receive depends on the size of your system and its location (solar irradiation varies across Australia).
Here's the important part: you don't actually handle the STCs yourself. Your solar installer usually takes care of this. They estimate the number of STCs your system will generate over its lifetime (up to 2030, when the scheme ends) and offer you an upfront discount on the system's price in exchange for assigning the rights to those STCs to them. The installer then sells the STCs on the open market.
Essentially, the rebate lowers the upfront cost of your solar system, making it more affordable.
What's Changing with the Rebate?
The SRES scheme is designed to phase out by 2030. This means the number of STCs your system is eligible for decreases each year. The deeming period, which is the number of years of electricity generation that STCs are calculated for, reduces annually.
So, what does this mean in practical terms? It means that, all other factors being equal, the upfront discount you receive on a solar system will gradually decrease each year until the scheme ends. Therefore, the later you install your system, the smaller the rebate you'll receive, and potentially the higher the initial cost will be.
How This Impacts Your Solar System Cost
The reduction in the rebate directly affects the initial investment required for your solar system. As the STC incentive diminishes, you'll need to contribute a larger amount upfront.
However, it's crucial to remember that the rebate is just one piece of the puzzle. Other factors also influence the overall cost and return on investment of your solar system:
- Equipment Costs: The price of solar panels, inverters, and batteries can fluctuate due to supply and demand, manufacturing costs, and technological advancements.
- Installation Costs: Labour and installation costs vary depending on the complexity of the installation, your location, and the installer you choose.
- Electricity Prices: Rising electricity prices actually improve the financial viability of solar, as you're saving more money on your electricity bills.
- Feed-in Tariffs: The amount you receive for exporting excess solar energy back to the grid (feed-in tariff) impacts your overall savings.
- Self-Consumption: How much of the solar energy you generate that you use directly in your home or business.
Maximising Your Solar Investment Despite Rebate Changes
Even with a gradually decreasing rebate, solar power remains a smart investment for many Australians. Here's how to make the most of it:
- Act Sooner Rather Than Later: Given the phasing out of the rebate, installing sooner will ensure you receive a larger upfront discount.
- Increase Self-Consumption: The more solar energy you use directly, the less you need to buy from the grid. This maximises your savings. Consider running appliances during daylight hours or investing in a battery to store excess energy for later use. A home battery allows you to store solar energy when your system is producing excess, for use later in the day when the sun has set.
- Shop Around for the Best Deals: Get quotes from multiple installers to compare prices, equipment, and installation costs.
- Consider a Battery: While adding to the initial cost, a battery can significantly increase your self-consumption and reduce your reliance on the grid, particularly as electricity prices rise. A battery system allows you to store excess solar generated power, for use later when the sun is not shining.
- Understand Your Electricity Usage: Analyse your electricity bills to understand your consumption patterns and determine the optimal size and type of solar system for your needs.
- Explore Financing Options: Many financing options are available to help you spread the cost of your solar system over time.
The Bottom Line
While the solar rebate is decreasing, it doesn't necessarily mean solar is becoming unaffordable. By carefully considering all the factors involved and taking steps to maximise your self-consumption, you can still enjoy significant savings and contribute to a cleaner energy future.
