Australia’s vast landscapes and abundant sunshine make it an ideal location for solar farms, a key player in the nation’s journey towards renewable energy. As climate change concerns mount and the global community shifts towards sustainable energy solutions, solar farms are becoming increasingly crucial. This blog explores the concept of solar farms, their workings, costs, and power production capabilities, spotlighting Australia’s largest solar farms.
What is a Solar Farm?
A solar farm, also known as a photovoltaic power station, is a large-scale solar photovoltaic (PV) system designed for the supply of merchant power to the electricity grid. They are significantly larger than residential or commercial solar setups, spreading over acres of land. These farms harness sunlight, converting it into electricity through thousands of solar panels systematically arranged across a field or desert area.
How Does a Solar Farm Work?
Solar farms operate on the principle of converting sunlight into electricity using photovoltaic panels. These panels contain solar cells made from layers of silicon or other materials that create an electrical field. When sunlight hits the panels, it excites the electrons in the solar cells, creating direct current (DC) electricity. Inverters then convert this DC electricity into alternating current (AC), which is compatible with the electricity grid and can be used to power homes, businesses, and industries.
How Much Does a Solar Farm Cost?
The cost of building a solar farm in Australia varies widely based on the project’s scale, location, and technology used. On average, the construction of a solar farm can range from $1 million to $1.5 million per megawatt (MW) of installed capacity. Factors affecting the cost include land acquisition, solar panels, inverters, labor, and grid connection infrastructure. Despite the significant initial investment, solar farms offer low operating costs and a sustainable energy source, potentially providing returns over the long term.
how Much Power Does a Solar Farm Produce?
The power production of a solar farm depends on its size, the efficiency of the solar panels used, and the amount of sunlight the location receives. Generally, a 1 MW solar farm can generate approximately 1,400 to 1,600 megawatt-hours (MWh) of electricity annually in Australia, enough to supply around 200 average Australian homes. Larger farms, with capacities of 100 MW or more, can power tens of thousands of homes and significantly contribute to reducing carbon emissions.

FAQs
A typical solar farm can produce between 1 to 2 megawatt-hours (MWh) per acre per year. For instance, a 100 MW solar farm might cover around 200 to 500 acres and can generate enough electricity to power approximately 20,000 to 40,000 average homes annually.
The number of solar panels in a solar farm can range from a few thousand to over a million, depending on the farm’s capacity. For a rough estimate, a 1 MW solar farm typically requires about 3,000 to 4,000 solar panels. Therefore, a larger farm with a capacity of 100 MW could have between 300,000 to 400,000 solar panels.
The time to build a solar farm can vary from a few months to over a year, depending on the project’s size, complexity, and various regulatory and construction processes. Smaller solar farms (1-20 MW) might be completed in 6 to 12 months, while larger projects (over 100 MW) could take 1 to 2 years from planning to operational status.
The largest solar farm in Australia is Sun Cable’s Australia-Asia PowerLink project in the Northern Territory, which, when completed, is expected to be one of the world’s largest solar farms. However, among operational farms, the Western Downs Solar Farm in New South Wales is one of the largest, with a capacity of over 400 MW.
