Choosing your system size

When choosing your solar system, it’s important to find the right size to suit your needs. Some things to consider when choosing your system size include:

Your renewable energy goals

How much solar power you would like to be able to use? For example, would you like a system that is big enough to meet most of your electricity needs?

Your budget

It’s important you choose a solution you’re comfortable with. While a bigger system will cost more in the shorter term, in the long term it could save you much more on your electricity bills than a smaller system.

Your current electricity use

Take a look at your last bill for an idea of how much electricity you currently use.

Your roof design

Consider how much space is available and the orientation of your roof.

Maximise your solar system by adding a battery

Adding a battery to your home-grown electricity generator (that's your solar system), allows you to improve your self-consumption of the energy that you generate, so you can maximise your solar savings once the sun goes down.

How does a solar battery work?

  1. The sun shines on your solar panels.
  2. Your solar panels turn this solar energy into electricity, then send it through your inverter to use to power the lights, heating and cooling systems, electrical equipment and appliances you use in your home.
  3. If your solar panels make more electricity than you use during the day at home, this is generally fed back into the electricity grid. At night, you would usually draw from the grid to power your home.
  4. If you have a solar battery, your excess power could instead be fed into your battery. Your solar battery will store electricity and charge the battery, in a similar way to how your mobile phone battery stores its electrical charge.
  5. A solar battery has an inverter which can then turn that stored solar charge into electricity for you to use when the sun goes down.
  6. Once your solar battery has been depleted, you would then draw electricity from the grid again until your solar panels are producing electricity again on the next sunny day.
