Residential Solar PV Price Index – October 2017

Average solar system prices hold stable for the third month in a row, with the average price per watt ($/W) for an residential solar system installation coming in at about $1.44/W. The most popular and best value solar system size is still 5kW, costing about $1.14/W or $5,700 for a fully installed system. (Due to a temporary paucity of data, pricing data for the ACT for this month has been carried over from the September figures.)

Average solar PV system prices for October 2017

Prices in the table below include both the up-front incentive available for small-scale systems through the Renewable Energy Target (STCs) and GST – they represent the total out-of-pocket cost 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 fewer than 3).

Prices for each system size are colour-coded. (Dark red for highest, dark green for lowest, yellow for middle. Note that for Darwin there is no 5kW pricing; this is because Darwin installers prefer to list pricing for 4.5kW systems instead, as there are additional hurdles for connecting solar systems above that size to the grid. We have recently revised our table to more accurately reflect this.) *Data from September 2017.
