In 2025, the cost of an individual solar panel in Australia ranges from $80 to over $300 per panel, depending on brand and wattage. Budget panels from Jinko, Trina, or Seraphim retail for under $150 each, while premium modules like SunPower or REC cost $250–$300+. A typical home system uses 14–28 panels.
Maintenance: Although solar farms have lower maintenance costs than traditional power plants, periodic cleaning and repairs are essential to ensure maximum efficiency. According to recent estimates, the cost of setting up a solar farm in Australia can range between $1 million to $1.5 million per megawatt (MW) of installed capacity.
While the initial investment and land-use issues present challenges, the long-term environmental and economic benefits are undeniable. As solar technology costs continue to decline, and with government support, solar farms will become an even more viable and essential component of Australia's energy landscape.
The Cost Spectrum: The choice between a value-oriented “budget” panel and a high-performance “premium” panel can have a substantial impact on the upfront cost. A budget-friendly panel from a reputable manufacturer like Jinko might cost around $130 per unit. In contrast, a premium panel from a brand like SunPower could easily exceed $290 per unit.
At the time of its installation, Adelaide Airport's 1.17MW rooftop solar system was Australia's largest airport solar installation, but that record has since been shattered by larger airports across the country.
The cost of solar panel installation in Australia averages around $1,000 per kW. For a popular 6.6kW system, expect to pay between $5,000 - $8,500 for good components and an installation that will last. Over their lifetime, our analysis shows that rooftop solar panels can produce electricity at close to 4c per kilowatt-hour.
With a commitment to renewable energy, Brisbane Airport Corporation will be adding more rooftop solar panels to our existing solar system. at the International Terminal.
Adelaide Airport has completed the installation more than 3,800 solar panels on its international and domestic terminal rooftops, adding a further 2.2 megawatts of generation capacity and tripling the size of total PV installed.
In addition to 55 Australian large-scale energy storage projects, the Smart Energy Council has identified more than 120 large-scale solar projects. These large-scale solar projects, totalling more than 9 GW, have been completed, commissioned or are in the pipeline. Many would be suitable for energy storage to be added.
purchase in Australia. lithium-ion technologies. installed indoors. This report is a comprehensive analysis of the Australian energy storage market, covering residential, commercial, large-scale, on-grid, off-grid and micro-grid energy storage.
Bloomberg New Energy Finance estimates that by 2020, solar batteries will be the dominant form of battery storage. Analysis by the Smart Energy Council from the survey and interviews with market participants for this report suggests battery manufacturing costs are likely to fall in Australia by around 15% each year to 2020.
The report identifies 55 Australian large-scale energy storage projects which are either existing, planned or proposed. Excluding pumped hydro, these represent over 4 GWh of storage. 9 gigawatts (GW) of capacity have been completed, planned or are in the pipeline. Of those, 19 have been completed and another 36 have reached financial close.
Solar Choice has been tracking the cost of commercial solar systems in Australia since 2014, publishing average figures each month in our Commercial Solar Price Index. Based on this data we can see the average cost of a 50kW system as of August 2024 is $50,480 including the STC rebate and GST.
For a more exact figure, contact our specialists for a free quote. For commercial 50kW solar systems in Australia you will be looking at starting prices of $45,000 to $50,000 after rebate, excluding GST. For higher quality components from top tier manufacturers with highly efficient inverters the prices will start from $55,000.
On average, a 50kW solar system will cost around $49,068, including government rebates and other incentives. The true range depends on your location and the brand of solar panels and inverter you go with. The installation cost is usually included in this price range, as a certified installer can only do it. What's the payback period on 50kW solar?
Most 50kW solar systems in Australia have an average payback period of 4 years. However, depending on your location and energy consumption patterns, the system may pay back in as short as 3 years, or extend to around 5 years. The more energy you consume from your 50kW solar system, the faster it will pay itself back.
