Based on data from Solar Choice’s installer network database, the average price of per watt of a fully installed residential solar system in Australia as of May 2016 is about $1.66 (including GST, after STCs) – up slightly from last month. For the first time, in this month’s Index we have included (somewhat limited) pricing data for Darwin, NT.
Average solar PV system prices for May 2016
Prices in the table below include both the up-front incentive available for small-scale systems through the Renewable Energy Target and GST – they represent the total retail cost of the system to the customer. In situations where there are fewer than three installer offerings, we have left the fields blank.

All $/W solar system prices (Historic)
The chart below provides an at-a-glance look at solar PV system pricing trends since August 2012. Data points are the average of average $/W for each system size (1.5kW-5kW until Nov 2013, then also including 10kW from Dec 2013).
A note about the ‘Solar Choice discount’
From August 2012 until November 2015, calculations for our monthly Residential Solar Price Index articles excluded the discount available through Solar Choice network installers exclusively to Solar Choice customers. From last month we have excluded this figure, which works out to approximately 14c/W in most instances. The chart below retroactively applies this amount to every month since the Price Index’s inception.
