The average price of rooftop solar installation increased slightly between May and June to $1.68 per watt, according to figures from Solar Choice’s installer network database. In line with long-term trends, prices were highest in Hobart and lowest in Perth.
The figures in the tables below are based on quoted prices from our network of 100+ installers across Australia, who have been selected for their reputation as quality operators with favourable customer reviews. All prices in the tables below are after the STC incentive has been applied and inclusive of GST; they represent the total retail cost of having the system installed.

About Solar Choice
About this data
Since 2012, Solar Choice has been tracking residential solar PV system installation price trends in Australia’s capital cities (with the exception of Darwin). The data that we publish has been referenced by a wide range of organisations both inside and outside Australia – from government bodies, not-for-profits and academics to financial services companies and – of course – residential solar PV system shoppers and installers.
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 100 accredited solar installation companies across Australia.
All prices that appear are net of the federal STC incentive and inclusive of GST. In most instances, prices do not incorporate meter change fees, and exclude travel costs or additional charges for special circumstances (e.g. slate roof or 2-story+ building). Installers’ premium and microinverter/power optimiser offerings are not included in our calculations.
A more in-depth version of this month’s index is available here on the Solar Choice website. Solar Choice also publishes monthly insights about commercial solar PV system prices (10kW-100kW), the most recent of which can be found here.
