1. Generating power that you use
2. Using power that you didn’t generate
3. Generating power that you don’t use!
Generating the power you use is probably why you chose solar in the first place: you get to create and use your own energy.
Using power that you didn't generate is for when you are using more electricity than you are creating and that use is charged to you on your bill at the general electricity rates. This charge is different to the feed-in-tariff rate (which we talk about next), because it takes into account all the costs involved in generating and distributing the electricity (which you don’t have when you generate power at home). Imagine if you had to put in and maintain the network to send the power back to us!
Generating power that you don’t use is where you can make money back from the electricity that you generate and that comes off your bill. This amount is shown on your bill as a credit* and is calculated based on a feed-in-tariff (FiT) rate.
Feed-in-tariff rates are set by the independent Tasmanian Economic Regulator each year.
The FiT you receive depends on the size of your solar system, and whether you are a business or residential customer.
Every customer with an eligible solar system receive the Standard Feed-in-Tariff. Some customers previously received the Transitional Feed-in rate which ended on 31st December 2019. You can read more about this here.
|Standard FiT customers Standard tariff (X4I) – 140||
|Transitional FiT residential customers||This rate applied to all regulated residential customers that previously held the Legacy feed-in (X1I) – T110) for a solar system installed or approved before 31 August 2013. Customers previously on this rate now receive the standard FiT for residential customers.||Ended 31 December 2019|
Non-Qualifying feed-in (X6I) – 160: (for customers with a solar system too large to qualify for X4I/140). If you have this tariff, please contact us on 1300 13 2003 (Monday - Friday, 8am-6pm) to discuss your FiT rate.
Visit the Regulator website to learn more about how the Regulator sets the feed-in tariff.
Thinking about getting solar but don't know where to start? Let us explain the process!
Solar export is any excess power your system has generated (that you have not used yourself) which is exported into the electricity grid. You receive a credit for this power which is shown on bill and is calculated based on a feed-in-tariff (FiT) rate.
Your 'gross' solar is all of the electricity produced by your solar system, this is measured by your solar inverter. Your 'net' solar is the excess solar generation (what you don't use yourself) which is sent to the grid (you receive a rebate for this power known as the Feed-in Tariff (FiT). This power is measured on the same electricity meter as your household consumption.
When you're on aurora+, you'll see your 'net' solar displayed on your app, so you'll know how much solar you're exporting each day down to the hour.
There are a couple of reasons why the usage comparison graph and the average daily cost on the back page of your bill may not be accurate when you have solar.
The usage comparison graph compares the total amount of kWhs used in your home in the billing period, to the same time last year (if possible) as well as the average usage of other Tasmanian households.
Because we do not have access to the amount of solar you generate and use yourself, this cannot be added to the total of kWh used in your household.
As well, your exported solar energy (the solar you don’t use yourself and feed into the grid) is added to the total of your kWh used.
We are aware that this is not ideal and apologise for any inconvenience.
When figuring out how much power your solar system should be producing, there are two main things you'll need to determine - the size of your system and the amount of average sunlight hours where you live.
