How does your estimate tool work?

The recommendation and electricity bill savings estimate tool takes the information you provide from your electricity bill, home set-up, and building information to suggest the right size system for your needs. It will then estimate your electricity bill savings [each month] if you were to install that system.

It considers:

  • Electricity rates/tariff: Rates/tariff you are currently on from the electricity bill you upload
  • Electricity retailer: If you don’t have your electricity bill available, the system will use the popular plans available from the retailer you enter
  • Electricity use: Taken from your electricity bill and Market Settlement and Transfer System (MSATS), this provides the average daily use of your home
  • Home set-up: The big energy using items in your home, like EVs and Pools
  • Roof information: Shading (e.g. tree overhang), roof and eaves height, roof material (e.g. tiled), roof shape, roof pitch, roof north facing size – taken from publicly available information
