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 100 solar installation companies across Australia. Although all pricing calculations do account for federal incentives and GST, they do not incorporate meter installation fees or additional costs, such as ground-mounting or grid connection studies. The discount available to Solar Choice customers is also excluded from calculations, as are prices for ‘premium’ installer offerings. Median high and median low prices are the arithmetic averages taken from the range of high and low prices on offer across cities for each system size.
