Solar PV Price Check - August

A year on from when we started analysing solar prices in Australia and it's clear prices have come down significantly, particularly for larger systems.

The August 2013 Solar PV Price Index marks one year since Solar Choice began publishing solar system installation prices. While it is clear that figures have come down markedly for 4kW and 5kW systems since that time, cost reductions for the smaller system sizes – although present – have not been as distinct.

This month’s figures were derived from a larger data set than usual for Sydney, Brisbane, Adelaide, and Perth. Conversely, the number of installers included in the Hobart calculations shrank slightly, yielding numbers that would at first glance appear to reveal huge installation price reductions there.

Average installation costs by city & system size

The table below contains the average solar system installation prices for all capital cities besides Darwin

Although Sydney and Perth are still home to the least expensive systems on offer (see $/W table in the following section), this month Hobart boasts the lowest average system prices when it comes to larger solar systems (3kW, 4kW, 5kW).

It is important to note, however, that only two installers were included in the Hobart calculations, with the remaining installer – offering a zero-down solar leasing deal – excluded. Meanwhile, the highest average system prices can now be found in Melbourne and Brisbane.

$/W solar system prices for August 2013

The following table shows STC-inclusive installation prices for 1.5kW, 2kW, 3kW, 4kW and 5kW solar systems. Where explicitly detailed in installer data, STCs accounted for a discount of about 66c per watt for the Zone 3 cities (Sydney, Perth, Adelaide, and Brisbane), and about 55c/W for Zone 4. No STC numbers were available in the data from Hobart or Canberra installers this month.

Solar PV system prices to date

Average system prices continued to fall in the ACT (albeit more gradually) following the sharp drop that was observable between June and July. Prices in most other cities have similarly fallen in varying degrees, except for Sydney and (to a lesser degree) Brisbane, where slight rises were observable, possibly due to the inclusion of new installer data in those cities.

The biggest change, however, as noted above, was in Hobart, with apparently sharp reductions across all system sizes.

About this data

Tables and charts included in this article were created using data from Solar Choice’s installer network database, which contains regularly-updated pricing and product details from over 125 solar installation companies across Australia. Prices do not incorporate meter installation fees or additional costs for difficult installations. The discount available to Solar Choice customers is also excluded from the calculations, as are prices for ‘premium’ installer offerings.
