Average residential solar system prices took a dip across the board between August and September, with almost no instances in which they increased. The trend was likely spurred by the recent release of the Renewable Energy Target review panels’ recommendations that the scheme be abolished or significantly scaled back, with a number solar installation companies lowering prices to increase competitiveness as demand surges in anticipation of cuts to the subsidy for small-scale (<100kW) systems.

The miniature ‘boom’ that the announcement set off seems to be the cause of the fall in indexed average prices to an unprecedented $1.90 per watt (after STC subsidy)–the lowest seen since Solar Choice began keeping records in August 2012. Importantly, the continuing decrease in retail prices (which are for a full installation, after the STC subsidy provided through the RET) stands in contrast to trends in the cost of solar PV modules. The following chart, included in Solar Business Services’ submission to the RET review panel (PDF), captures how global solar PV module prices have changed since February 2012. In particular, the chart highlights the exaggerated inflationary effect that the foreign exchange rates have on the wholesale cost of modules imported to Australia.

Since only one solar panel manufacturer operates domestically here, virtually all of the solar panels used in Australian installations are imported from abroad. The takeaway from the above chart, when looked at in conjunction with the ones below, is that installation companies are likely to be feeling a big squeeze at the moment as wholesale product prices increase along with pressure to keep installation prices low to stay competitive. It also brings home the importance of the Renewable Energy Target to the ongoing health of Australia’s solar industry, which is still very much at the mercy of global forces such as the broader PV manufacturing sector and foreign exchange rates.

About this data

Tables and charts included in this article were compiled 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 ordinarily incorporate meter installation fees or additional costs for difficult installations. The discount available to Solar Choice customers is also excluded from calculations, as are prices for ‘premium’ installer offerings. Except in the final chart, average pricing figures for all of Australia are not weighted.

Hi can I was wondering if you have a table without the government subsidies for solar PV system prices? I’m after how much the subsidy actually is.

Hi Ed,

If you take a close look at the article you can see what the average STC ‘discount’ is for each of the cities included. To keep it simple, we divide this between ‘zone 3’ cities (Sydney, Adelaide, ACT, Perth, and Brisbane) and ‘zone 4’ cities (Melbourne and Hobart/Tasmania). To get a rough idea of the unsubsidised price, you can simply add on these amounts to the $/W system prices for the appropriate cities and then multiply by system size. Hope this helps.

Dear Sir/Madam,

This article presents a table for the price of solar PV systems in September 2014. Would the panels cost the same if it is purchased from Australia and then exported to another country? That is regardless of the fees for installation.

Hi Mohsen,

The prices shown in the article are full the full cost of an installation, not for the cost of panels–prices of individual components are not itemised.
