How Much Can Solar Energy Save You?
As an electrician and solar installer, many people ask me – How much can I save with solar? Is it really worth it? How long will it take to recover the money invested?
It is evident that more and more people are making the switch to solar, and that is because solar is a great option to save money and obtain energy from an inexhaustible source -the sun.
The Solar Savings Calculator below will help you get an idea of what you can save with solar, depending on your current consumption, and the size of the solar panels you want to put on your roof.
Once you have set the requested parameters, you will be able to find out your:
- Estimated Annual Self-Consumption Savings
- Estimated Annual Feed-in Savings
- Estimated Total Annual Savings
If you are not sure about some of the steps from the Solar Savings Calculator, you can check the information below. Please bear in mind that these numbers are indicative and that each situation needs to be evaluated individually by solar experts.
Daily Energy Usage
One of the first steps to determine how much you can save with solar, and which system is right for your home is to look at your electricity bill. For example, an Australian family can consume 41 kWh per day. If you multiply that number by the QLD average electricity rate, ($0.23545 per kWh) you’ll find that the typical Australian family is spending over $9 a day, which will result in more than $3,000 per year on electricity alone. ($9/day x 365 days = $3,523.50/ year).
You can find your daily consumption on your electricity bills.

Solar Panel Orientation
What is the best direction to face solar panels in Australia?
When solar took off around 10-years ago, we did the best with the information we had. One common conclusion that we were all told was that North-facing panels were the only way, but, it turns out that there is more than one way to skin a cat.
The sun rises from the East and sets in the West, so by having a system with panels evenly split between East-West, we can achieve the same daily production of a North-facing roof. But sometimes, when there are no other options, having panels on a South-facing roof can still yield results!
Solar System Size
There is no one-size-fits-all solution when it comes to solar panels. Giving a closed answer to this question without a previous household energy assessment is complicated.
The power of the system you’ll need depends on several factors. You can read more about this on our article “Solar Panels: The Ultimate Guide to Get the Right Solar System for Your Home.”
We have created this table to give you an approximate idea of the number of solar panels and the size of the installation. Remember that these numbers are approximate and that several factors can affect the actual size of your system.
Feed-in Tariff
As you may already know, you can sell the extra energy you produce to the Queensland electricity network. The Queensland Government’s Solar Bonus Scheme pays a feed-in tariff for the surplus electricity generated from solar power systems. Each company has different solar feed-in tariff rates and conditions.
However, the average rate in Queensland is 7.5 per kWh. If you need help finding the best company to sell the extra energy that you produce, you can contact us and we will be happy to help you with any questions that you have.
Solar Payback Period
The Payback Period simply means how long it takes for the savings from your electricity bills to equal the value of installing a solar energy system.
When talking about Payback Periods, I am often asked, “how long does it take to recover the initial investment?” In other words, how long will it take for you to save on your electricity bill?
Well, I have to say that it depends on many factors, and one of them is the geographic location where you live. If you take a look at the graph below, you will notice that the bigger the system you install, the shorter the payback period, even though the initial investment is higher. It seems unreal, right?
But, it’s true. And, that is the reason why many people are now turning to solar energy. In fact, as you can see below, Queensland is one of the locations with lower Payback Period times, which makes it even better for Queenslanders to invest in a solar system.
