The Sun Tax Explained

If you have Solar on your roof you might have heard the buzz around the country lately about the Sun Tax. Last week Channel 9’s A Current Affair broadcast a case study example of how people with large solar panel systems are being charged by selling excess kW’s back to the grid.

Officially known as the solar export tariff, this proposed change has sparked plenty of discussion.  

But what does it actually mean for you?  

Let's break down how the Sun Tax will work, its potential costs, and how it might impact you.

What Exactly is the Sun Tax?

The Sun Tax is an export tariff that's designed to allow less pressure on the grid system by taxing people on the excess kW their home solar systems generate.  

Approved by the Australian Energy Market Commission (AEMC) in August 2021, this tariff is part of a broader effort to balance our electricity grids more effectively.  

Put simply: Currently, when we send our excess solar power back to the grid, we get paid a feed-in tariff (FiT) regardless of when we export it – whether it's high demand or not-so-busy times.  

The 'sun tax' changes this by encouraging us to export our solar energy when it's needed most, like during peak demand periods, 5pm – 9pm in the evenings.  

Conversely, exporting during times when the grid is saturated with solar power (think midday sun blasting across the country) could see us paying a small fee.  

Now, the burning question:  

How will this affect your wallet?  

Well, the idea behind the 'sun tax' isn't to gouge us solar enthusiasts but to incentivize smarter energy use.  

By aligning our exports with peak demand, we can earn more credit when electricity is most valuable.  

Plus, this approach could help reduce strain on the grid, which benefits everyone in the long run.

Why Switching to Solar is still important despite added Tax

The Sun Tax is only conditional on a certain number of factors.  

Therefore, switching to solar still makes a lot of sense, and here’s why:

  • Financial Benefits: Even with the Sun Tax, solar panels remain a solid investment, reducing and in some cases eliminating electricity bills. Solar systems slash those hefty electricity bills and can still earn you credits through smart export timing.
  • Environmental Impact: Solar power is clean and renewable, reducing our carbon footprint and contributing to a greener Australia.
  • Energy Independence: By switching to a Solar system, you’re making your home become energy independent, putting less reliance on a power grid that is under pressure, which leads us to our next point;
  • Blackout Protection: With a battery in place (hybrid system) you protect yourself against black-outs and brown-outs, which are becoming more prevalent these days as we make the switch to renewable energy.

As we navigate these changes, the key takeaway is that going solar in Australia is still the smartest move.  

It's about adapting to a more dynamic energy landscape where our choices can make a real difference.  

Whether you’re thinking about installing solar panels or already soaking up solar energy technologies, the sun tax is simply part of evolving towards a more sustainable future.
