The origins of solar energy
The use of solar energy dates back to ancient civilisations that harnessed sunlight for warmth and agriculture. However, the modern foundation of solar technology was laid in the 19th century:
- In 1839, French scientist Edmond Becquerel discovered the photovoltaic (PV) effect, where certain materials generate electricity when exposed to sunlight.
- In the 1950s, researchers at Bell Labs in the United States developed the first silicon solar cell, achieving an efficiency of about 6%.
- By the 1970s, solar panels began commercial production, leading to widespread adoption in various sectors.
Early adoption of solar power in Australia
Australia recognised the potential of solar energy early on, given its abundant sunshine. The first major implementations of solar technology included:
- Solar water heaters were installed in the 1950s, particularly in remote areas.
- The use of solar panels in off-grid rural communities and regions in the 1970s, reducing reliance on diesel generators.
- Government funding for solar research in the 1980s, laying the groundwork for future advancements.
Key milestones in solar energy development in Australia
The milestones in solar energy in Australia mark significant advancements in technology and policy. Some key moments include:
- 1980s – The Australian government began funding research into solar photovoltaics (PV), fostering innovation in solar technology.
- 1990s – CSIRO and Australian universities developed improved PV cell efficiency, positioning Australia as a leader in solar research.
- 1992 – First solar power plant: Australia’s first commercial solar power station was established in White Cliffs, New South Wales, producing energy for a remote community.
- 2000s – The Renewable Energy Target (RET) scheme was introduced, incentivising solar installations for homes and businesses. The introduction of financial incentives, including the Solar Homes and Communities Plan, rapidly increased residential solar installations.
- 2010s – The cost of solar panels dropped significantly, making rooftop solar more affordable.
- 2020s – Advanced solar battery storage and smart grid technology have made solar power a reliable, year-round energy source.

The evolution of solar technology in Australia
Significant improvements in efficiency, affordability, and storage capacity have marked the evolution of solar technology. Key advancements include:
- Increased panel efficiency: Modern solar panels reach efficiency levels above 22%, compared to 15% a decade ago.
- Introduction of bifacial panels: These panels generate electricity from both sides, increasing energy production.
- Integration with battery storage: The rise of home battery systems, such as the Tesla Powerwall, allows households to store excess energy for later use.
- Smart solar technology: AI-driven energy management systems optimise solar production and consumption.
Government policies and incentives driving solar growth
The late 20th and early 21st centuries witnessed a surge in solar energy adoption, driven by government incentives and falling technology costs.
Australia’s government has played a vital role in supporting the solar industry through various initiatives:
- Small-scale Renewable Energy Scheme (SRES): Small-scale Renewable Energy Scheme (SRES) provides financial incentives for residential solar panel installations.
- Feed-in Tariffs (FiTs): Homeowners with solar panels can return excess energy to the grid through feed-in tariffs.
- Large-scale Renewable Energy Target (LRET): Encourages the development of solar farms and utility-scale projects.
- State-based incentives: Various state governments offer additional rebates and incentives to encourage solar adoption. For more information, visit our Australian Solar & Renewable Energy Rebates and Incentives page.
The present and future of solar energy in Australia
- Today, Australia boasts over 3 million solar-powered homes, making it a global leader in solar adoption per capita.
- The cost of solar panels has dropped over the past decade, making it more accessible to businesses and households.
- Advanced battery storage solutions promise greater efficiency and sustainability.
