According to the Australian PV Institute (APVI), Australia is the leading solar per capita in the world, with one kW per person by the end of December 2022. The country had solar per capita of more than 800 W per person, with Germany in the second position with 650 W per person. According to a report, during December 2021, Australia had nearly 25.4 GW of installed solar capacity, with the overall solar installations doubling every three years in Australia. In 2021, Australia had installed more than 4.5 GW of rooftop solar capacity over 350,000 households and companies, providing 25,000 employment opportunities in sales and installations. As per the report, the solar industry witnessed several challenges due to the Covid-19 pandemic and lockdowns. Solar photovoltaic (PV) remains the most cost-effective and generating energy. It has become a popular investment with homes and businesses to control their energy bills and proceed towards a net-zero emissions economy. Last year, the aggregate system size installed in the small-scale solar category increased to 8.8 kW, costing $700-10,000 and having a return on investment of about 20%. In 2020, the average rooftop solar installation was 8 kW. Solar systems power more than three million houses and small businesses. It is complemented by large-scale solar installations and powering more households and businesses with clean and green energy. The Secretary of APVI, Renate Egan, said that solar power growth in Australia is 25% and likely to increase in solar per capita. According to a report by Australia's Clean Energy Regulator, during the second quarter (Q2) of 2021, the country installed around 729 MW of rooftop solar capacity, with an 8% growth, compared to 677 MW during the same period last year.
