Debunking the Sun Tax

Updated: Jul 30

Are you concerned about the so-called "sun tax"? It's not just you. Several homeowners are considering whether solar panels are still a wise decision in light of the media's exaggeration of concerns around the new solar export fees. The solar tax may not be as detrimental as you may believe, though.



Learn the truth about the sun tax, how much it will impact you, and why solar energy is still a smart investment in spite of the additional fees in this article.


The term "sun tax" describes the increased levies imposed on solar exports in an effort to control the growing amount of solar energy that is fed back into the electrical grid. These fees are a component of a two-way pricing structure that aims to strike a balance between the expenses associated with grid stability and the advantages of solar energy. In essence, households that install solar panels will pay a nominal cost for the electricity they export back to the grid when it's busy and stressed.


Due to the media's exaggeration of these accusations, many present and potential solar panel owners are now deeply concerned. Fear has been stoked by headlines that highlight the possible expenses without giving the whole story. In actuality, the fees are not meant to penalise solar panel owners, but rather to promote the more economical use of solar energy.


For instance, SolarQuotes claims that during peak hours, the costs may be as little as 2 to 3 cents per kilowatt-hour. Taking into account the overall savings from producing your own electricity, this is a doable expense.


As has been the case for a number of years, making the most of your solar energy comes from using the power you produce during the day rather than selling it to the grid for a dismal 7c/kWh. It is a straightforward process to programme the inverter to limit electricity going to the grid and prevent any export costs when the "sun tax" takes effect. In this manner, you will receive nothing for feeding surplus power into the grid, as opposed to receiving almost nothing.


The most important thing to remember is that even if these fees add a new expense, owning solar panels still has financial advantages.


What is the Financial Impact?


Understanding the financial implications of the sun tax is crucial for making informed decisions about investing in solar energy.


Although the thought of extra fees might initially seem overwhelming, a deeper examination shows that the cost is negligible in comparison to the overall savings and advantages of solar power.


1. Reasonable Fees: The export fees are comparatively cheap, estimated to be between two and three cents per kilowatt-hour during peak hours. To put this into perspective, the increased cost would be roughly $0.10 to $0.15 per day if you exported 5 kWh of electricity each day during peak hours. This comes to about $3 to $4.50 over the course of a month. The export fees are negligible in comparison to the hundreds of dollars you can save on your electricity bill each year.


2. Nett Savings: The nett savings from solar panels are still substantial even after the sun tax. A 6.6 kW solar system, for example, can save a normal household $1,000 to $1,500 a year on electricity expenditures. Even after deducting the estimated $50 to $100 in annual export fees, you will still have saved a significant amount of money.


3. Return on Investment (ROI): Solar panels continue to provide a significant ROI. Depending on system size and local electricity costs, most solar installations have a payback period of 3 to 5 years, regardless of the sun tax. Over the course of its 20–25 year lifespan, solar panels prove to be a financially smart investment, as savings continue to build after the payback period.


Why Investing in Solar is the Right Choice


1. Long-term Savings: The long-term savings from solar panels greatly exceed the little export fees, as they drastically lower your electricity expenses. The value of producing your own energy increases as electricity costs rise.


2. Advantages for the Environment: Purchasing solar energy lowers your carbon impact. You can aid in the fight against climate change and promote a sustainable future by producing clean, renewable energy.


3. Energy Independence: By lowering reliance on the grid, solar panels offer energy independence. This is especially helpful when there are power interruptions or when electricity costs are high.


4. Enhanced Property Value: Houses equipped with solar panels typically fetch a greater price and sell more quickly than those without. Prospective purchasers are aware of solar energy's long-term cost savings and environmental advantages.


Reducing Sun Tax




1. Energy Consumption Timing: Syncing your energy consumption with solar production is one of the best strategies to lower export fees. You can reduce the quantity of energy exported to the grid by utilising more electricity throughout the day while your solar panels are producing power. Utilising air conditioners, dishwashers, and washing machines during the hours of maximum sunlight can help you use more of the electricity you generate directly, which will lower your export costs. (Remember: The most important thing to keep in mind is that even if these fees add a new expense, owning solar panels still has financial advantages.)


2. Battery Storage: You can cut down on how much excess energy you send to the grid by making an investment in a solar battery storage system. You can reduce your dependency on the grid and avoid export fees by storing extra energy produced during the day to use in the evening or on overcast days. Battery systems can result in significant long-term savings and enhanced energy independence, notwithstanding the initial investment required.


3. Smart Inverters: By controlling the electrical flow between your solar panels, battery storage, and the grid, smart inverters can help you maximise the amount of solar energy you use. The impact of export fees can be decreased by configuring these inverters to prioritise battery charging and self-consumption over exporting electricity to the grid.


4. Monitoring and Management solutions: To monitor your energy output and consumption, use energy monitoring and management solutions. By giving you insights into your usage habits, these technologies can assist you in making well-informed decisions about when to use appliances and how to utilise energy most efficiently. You may lower your export charges by becoming more aware of your energy usage patterns.


5. Taking Part in Energy Trading Programmes: In certain areas, solar panel owners can sell their extra energy directly to other businesses or consumers through energy trading programmes. By taking part in these programmes, you may be able to offset the expense of export charges by earning greater rates for your exported energy than you would through conventional grid exports.


Don't Buy into the Media and Invest in Solar Today


Homeowners and prospective solar panel purchasers have rightly expressed anxiety since the sun tax was implemented. When considered appropriately, though, the costs associated with these fees pale in comparison to the overall advantages of solar power. Through the implementation of tactics aimed at reducing export duties and optimising internal usage, you can maintain substantial cost savings and make a positive impact on the environment going forward.



Solar energy remains a smart investment, offering long-term financial benefits, environmental advantages, and increased energy independence. Don’t let the fear induced by media reports deter you from considering or continuing your solar journey. With the right approach, you can navigate the new charges effectively and continue to reap the rewards of clean, renewable energy.
