The cost of residential solar panels in Australia has decreased significantly since they were first introduced in the early 2000s. According to the Australian Photovoltaic Institute, the cost of solar photovoltaic (PV) systems has fallen by over 80% since 2009, and by more than 50% since 2016.
The price of solar panels varies depending on factors such as the size of the system, the quality of the panels and inverters, and the cost of installation. As of 2021, the average cost of a 5kW solar panel system in Australia is around $5,000 to $8,000, including installation. However, prices can range from around $4,000 for a budget system to over $10,000 for a premium system.
While the cost of solar panels has decreased over time, there are still some issues that can affect the price and adoption of residential solar systems in Australia. One issue is the cost of installation, which can vary depending on the complexity of the installation, such as the roof design and any shading or obstructions. Another issue is the upfront cost, which can be a barrier for some homeowners, although there are various financing options available.
Additionally, changes in government policies and regulations can also impact the price of solar panels and the growth of the industry. For example, changes to feed-in tariffs, which are payments made to homeowners who generate excess solar energy and feed it back into the grid, can affect the financial viability of solar systems for homeowners.
Overall, while there have been significant cost reductions in the price of residential solar panels in Australia over the past decade, there are still challenges and issues that need to be addressed to encourage more widespread adoption of this renewable energy source.
