Solar Choice’s Commercial PV Price Index is published monthly to act as a bellwether for commercial-scale solar PV system pricing trends across Australia. Systems of 10kW, 30kW, 50kW and 100kW in capacity are included in the calculations. The Commercial PV Price Index is published as a complement to our residential PV Price Index articles, which include systems 1.5kW-10kW in size.
The tables below offer a look into pricing trends for commercial PV systems 10kW to 100kW in capacity, but it is important to note that they are by nature indicative only; the inherent complexity of design, installation and grid connection of larger systems means that there is rarely a one-size-fits-all solution.
Numbers in the table below include the STC incentive available through Australia’s federal Renewable Energy Target (100kW is the upper capacity limit for STC eligibility). Depending on the city and installer, STCs shaved between about 63¢ to 76¢ off the price of each watt of installed capacity.

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. 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. 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.
