  • See what the financial implications may be for various installation options.
  • Manage your demand and see how demand management can improve your savings.

Please note:

  • At this time, the solar calculator is only accessible via desktop computers, laptops or other non-mobile devices.
  • You must have at least 12 months of billing data to use the tool.
  • Estimates for multi-unit properties and shared roof dwellings are not available.
