What can I save by using Solar for power?

Our governing body Seanz have developed a calculator to help customers like yourself figure out what you can save by having Solar. Feel free to have a play on it. Otherwise, get in touch and we can tell you what you are likely to save instead.

Solar Photovoltaic Savings

The below table provides indicative savings that can be achieved through a Solar PV installation. The table can help clarify payback periods based on expenditure vs savings.

Monthly Power-billHow many panels recommendedSize of array – based on 320 watt panelsSavings per year (up to)
$100-$1506 – 81.92 – 2.56kW $1100
$150-$2008 – 102.56 – 3.2kW $1400

*based on a consumer paying 30c per kW and consuming all of the power generated

Solar and Battery Savings

The below table provides indicative savings that can be achieved through a Solar PV and Battery installation. The table can help clarify payback periods based on expenditure vs savings.

You need more panels if you are purchasing Solar and Batteries compared to if you are just purchasing Solar. This is due to the need of now providing power to your Battery and making sure it is fully charged to allow you to have power at night.

Batteries provide power to you in a Power-Cut from the grid.

$200-$25018 – 22

  • Whatever your electricity bill is, we aim to reduce this by 80% or more with Solar and Batteries
  • The other obvious benefit of having a battery is still having power in a power-cut!
  • We have many types of Lithium Ion Batteries and will make a recommendation on the kW size of the battery once we have seen your power usage patterns.

Solar Photovoltaic panels and Hot Water Heat Pumps work great independently but even better when paired together. Not only do they provide a renewable and efficient energy source, the economic savings to be had are much greater than with Solar PV panels on their own, Contact us to find out more!

Savings are only estimates and it depends on how you use your power and what you pay per kW for your power.
