Evolution of Energy in Australia Through Rooftop Solar Panels

In 2003, a lone set of solar panels graced a Centenary suburbs rooftop, silently absorbing Queensland's sun. By 2004, a second set appeared in Indooroopilly downstream. In the following years, both areas saw modest annual solar panel growth.

In 2009, Indooroopilly installs 51 new solar panels, but further upstream, over a hundred new installations appear. Solar growth in both areas persists, with the Centenary suburbs doubling their pace, as seen on aerial imagery.

By 2022, only parks and industrial areas remain without solar panels. They've become a common sight on rooftops in both neighborhoods, fueling various household appliances.


The Evolution of Renewable Energy

Australia undergoes a significant technological shift. In the last two decades, over 90% of energy was from fossil fuels, but renewables now constitute 32% of energy generation.

The electricity sector is the primary source of fossil fuel emissions, crucial for climate change mitigation and achieving net-zero emissions.

To meet the 2030 federal target, Australia must more than double its renewable electricity production, with the scale and speed of this transformation posing challenges.

The National Electricity Market (NEM) aims to reach 100% renewables by 2050, necessitating five times more rooftop solar, nine times more large-scale wind and solar, and expanded energy storage through batteries and pumped hydro.

Coal power will be phased out by 2043, while gas "peaking plants" will remain temporarily, with the hope of eventually transitioning to renewable fuels like green hydrogen. Additionally, over 10,000 kilometers of new transmission lines must be built in southeastern Australia.


Rooftop potential

Australian rooftops play a crucial role in the energy transition.

Small-scale solar offers a direct, cost-effective way for individuals to contribute, benefiting from decreasing solar costs and fluctuating energy prices.

Solar adoption varies, with metropolitan areas having numerous installations but lower rates per dwelling or household, indicating distribution disparities.


Adoption of Solar Panels Throughout Australia

Differences in small-scale rooftop installation rates across postcode areas reveal varying levels of adoption, particularly in metropolitan centers.

According to Associate Professor Anna Bruce of UNSW's Energy Institute, rooftop solar gained momentum in Australia around 2012. A combination of global solar price reductions, government incentives, and rising electricity costs made it an appealing investment.

Australia's abundant solar resource and high rates of home ownership created ideal conditions for solar to become widely popular and highly competitive.

A decade on, the solar boom persists, with vast untapped potential.

Solar adoption is highest in regions with significant home ownership and individual dwellings.

Areas with many apartments and medium to high-density housing show lower rates of solar uptake.

Changing the Energy Landscape

Rooftop solar has reshaped the Australian energy landscape in several ways:

Reduced Costs: With decreasing solar panel costs, households and businesses realise that investing in solar tech not only promotes a cleaner environment but also provides cost-effective stability amid fluctuating fossil fuel energy prices.

Regional Variances: Rooftop solar adoption varies across Australia. Cities have more installations, but fewer per household, highlighting disparities. Areas with higher homeownership and standalone houses embrace solar, while regions with apartments have slower adoption.

Moving Ahead

Australia's dedication to renewable energy is on the rise, with thousands of rooftop solar panels meeting daily energy demands. To reach the 2030 goal of doubling renewable electricity and phase out coal power by 2043, the country must expand its solar capacity and transition to green hydrogen and other renewable fuels.

Australia's energy transition is ongoing, with infrastructure projects, investments, and initiatives driving a sustainable, renewable future. Rooftop solar remains pivotal, reducing emissions and advancing the nation's net-zero emissions objective.
