Current solar power system prices: Residential and Commercial

solar_choice_logo_finalSince 2012, Solar Choice has been publishing solar PV system prices for each of Australia’s capital cities across a range of popular system sizes. The data we use comes from our installer network database, which consists of about 100 prominent solar installation companies around the country. Installers in our network pre-fill pricing & product data for the free & impartial quote comparisons which we provide to our customers.

Over the years, our Solar PV Price index has become a industry reference point and overall bellwether for pricing trends, filling the gap in the absence of official government reporting on the topic. While it is not definitive, the PV Price Index is based on a robust sample of installers (usually 3-15, depending on the city), and provides reliable ballpark figures on the going cost of solar in Adelaide, Brisbane, Canberra, Darwin, Hobart, Melbourne, Perth and Sydney.

The tables below contain the most current residential and commercial solar system prices from around Australia. The system sizes included are 1.5kW, 2kW, 3kW, 4kW, 5kW, 10kW, 30kW, 50kW and 100kW.

Residential solar power system prices – January 2018

Prices in the table below include both the up-front incentive available for small-scale systems through the Renewable Energy Target (i.e. ‘STC discount’) and GST – they represent the total retail price of the system to the customer. We’ve left fields blank where there were only a small number of price points available in our database (usually less than 3).
