Average residential solar system prices (1.5kW – 10kW)

Residential solar power system prices

Prices in the table below include both the up-front incentive available for small-scale systems through the Renewable Energy Target (i.e. ‘STC discount’) and GST – they represent the total retail price of the system to the customer. We’ve left fields blank where there were only a small number of price points available in our database (usually less than 3).

In particular, the prices below encompass:

  • Supply & installation of solar panels
  • Supply & installation of a string inverter, microinverters and/or power optimisers
  • Supply & installation of all requisite cabling, safety & mounting equipment
  • The federal ‘discount’/incentive available for all accredited small-scale solar installations in Australia
  • GST
