Australia, a land famous for its vast farming lands and plentiful sunshine, is leading the way in a new collaboration: agrivoltaics. This innovative method, also called farming under solar panels, combines solar energy generation with farming on the same land. Imagine rows of crops growing in the partial shade provided by raised solar panels or livestock grazing peacefully beneath them. This isn’t a distant dream; it’s a quickly growing reality with major implications for Australia’s energy and food security.
What is agrivoltaics in Australia?
Agrivoltaics Australia refers to the practice of integrating solar panels with agricultural production—either by raising panels above crops or spacing them to allow farming below. This concept provides energy and agriculture to coexist, offering enhanced land-use efficiency and sustainability.
How agrivoltaics in Australia is designed
Projects vary, but these models are common:
- Elevated solar panels: Raised high enough for machinery or livestock to pass underneath.
- Spaced arrays: Panels arranged to let sunlight through between rows for crops.
- Semi-transparent or bifacial panels: Emerging technology to maintain light for crops while harvesting energy.

Why agrivoltaics matters in Australia?
Agrivoltaics offers a compelling solution to the increasing demand for both clean energy and food production in Australia. Traditional land-use practices often create a dichotomy, forcing a choice between dedicating land to farming or solar farms. Farming under solar panels breaks down this barrier, unlocking a multitude of potential benefits:
- Increased land efficiency: By utilising the same land for two purposes, agrivoltaics maximises resource utilisation and reduces land-use competition.
- Enhanced crop yields and quality: The shade provided by solar panels can protect crops from excessive heat and sunlight, reducing water evaporation and potentially improving yields and quality for certain crops.
- Water conservation: Reduced evaporation under solar panels translates to significant water savings, a crucial advantage in Australia’s often arid climate.
- Diversified income streams for farmers: Agrivoltaics offers farmers a stable income from electricity generation in addition to their agricultural output, enhancing financial resilience.
- Reduced carbon footprint: Combining food and energy production on the same land minimises the environmental impact associated with traditional farming and fossil fuel-based energy. Use Energy Matters’ carbon footprint calculator to calculate your household and business’s direct emissions.
- Improved microclimate for livestock: Solar panels can provide shade for livestock, protecting them from heat stress and improving their welfare.
Navigating the challenges of farming under solar panels
While the potential of agrivoltaics in Australia is immense, several challenges need careful consideration and innovative solutions:
- System design and cost: Designing agrivoltaic systems that optimise both energy production and agricultural activities requires careful planning and can involve higher upfront costs compared to conventional solar farms.
- Crop and livestock compatibility: Not all crops and livestock are suitable for integration with solar panels. Research is crucial to identify compatible combinations and optimise farming practices.
- Solar panel height and spacing: Determining the optimal height and spacing of solar panels is essential to ensure sufficient sunlight for crops and enable effective operation of agricultural machinery.
- Grid connection and energy storage: Integrating distributed agrivoltaic energy generation into the existing grid infrastructure requires upgrades and may necessitate energy storage solutions.
- Policy and regulatory frameworks: Clear and supportive policies and regulations are needed to encourage the adoption of agrivoltaics in Australia and streamline permitting processes.
Real-world cases in Australia
- Wool and pasture gains: Wool production rose by ~15% in some grazing under solar arrangements. – source: The Guardian – Farmers who graze sheep under solar panels say it …
- Government Planner’s Handbook: NSW EnergyCo’s new guide helps developers integrate farming with solar design in agrivoltaics projects in Australia.
- Research & workshops: Macquarie University and others are exploring agrivoltaics in Australia as a key to net-zero goals.
- Sheep grazing solar farms: At the University of Queensland (UQ) Gatton Solar Farm, grazing sheep under solar panels lowered mowing costs and promoted pasture health.
What’s next for agrivoltaics in Australia?
Agrivoltaics is gaining momentum in Australia, with pilot projects and research initiatives underway across the country. These projects are exploring various combinations of crops (such as vegetables, fruits, and grains) and livestock (like sheep) with different solar panel configurations. Research institutions and agricultural organisations are actively investigating the agronomic and economic viability of farming under solar panels in diverse Australian climates.
The future of agrivoltaics in Australia looks promising. As technology advances and costs decrease, we can expect wider adoption of this integrated land-use approach. Government support, industry collaboration, and continued research will be crucial in unlocking the full potential of solar-powered farming to contribute to a more sustainable and resilient future for Australia.
