In Australia, solar energy is undergoing a massive transformation as it is gradually moving to a phase where massive solar farms are up and running. The climate of Australia offers extremely high potential for solar energy harvesting in the form of intense sunshine and vast resources.
The graph below shows the total capacity of small scale solar PV installation from 2010 to 2019.
In the country, a record of 1.96 million residential rooftop solar systems and 78,000 commercial and industrial rooftop solar systems already existed by the end of the year 2018, which amounts to a total of 2.04 million rooftop solar PV systems.
It is such great news that as early as in 2018, over 200,000 solar PV systems were installed. The country of Australia ranks top in residential uptake of solar power.
The national average of free-standing households with an active solar PV system is 20%. By 2020 Australia has over 10.7 GW of rooftop solar in 2.4 million systems.
Solar power in Australia- statistics
Statistics show that solar power usage in Australia is growing at an immense rate.
As of June 2020, Australia has over 2.4 million solar PV installations with a combined capacity of 18,583 MW.

Australia is among the top ten solar companies in the world by rank and capacity. The country has an installed PV capacity of 12,959 MW by June 2019.
As per the 2019 Energy Transition Index by the World Economic Forum, the country ranked 43rd in the list of 115 countries. This report primarily focussed on the rates at which the energy performance of the countries improve and their readiness to embrace sustainable energy.

The 2018 report indicated that one in every five houses in Australia have solar power to cut down the cost of electricity. If this rate continues at a steady pace, soon by 2025, the country will reach 50% renewable capacity.
Studies done by the Australian Energy Market Operator indicated that rooftop solar would produce 85% more power than the 2017-18 financial year.
Another report by Green Energy Markets stated that in the first three months of 2019, a record number of rooftop solar panels had been installed in commercial and residential buildings.
This is an increase of 46% during the same period the previous year. At the beginning of 2019, 87 large-scale renewable energy projects are underway, and high utility batteries are installed all over the country.
Studies have shown that customers will save nearly $600 million on their electricity bills over the next twelve-year.
What are solar farms?
These are large scale solar installations which are used to collect the energy of the sun.

The most common methods are mainly by using PV(Photovoltaic) panels or using a similar method. A solar farm or sometimes referred to as a photovoltaic power station is a large decentralized array of solar panels providing electricity to the power grid.
From the perspective of a broader definition, solar farms could also include other ground-mounted arrays of solar panels capable of generating power for many households.
This concept of a solar farm can be associated with a utility-scale solar or community solar.
Are you wondering how a solar farm is different from commercial solar power systems or rooftop solar?
Solar farms operate as power plants, similar to that of a hydroelectric power plant or natural gas power plant to generate electric power for the consumers. But the extent of power produced may vary depending on the number of panels used.
A solar farm feeds energy into the electricity grid just like a fossil or nuclear power plant does, except that there is no pollution of any kind and uses very little water.
In a solar farm, solar panels are installed on short towers over an area as huge as 100 acres. Although most of the existing solar farms are owned and operated by independent power producers, the number of projects owned by communities is also increasing.
The present-day solar technology requires approximately 2.5 acres of solar panels in high-intensity sun areas to produce a megawatt of electric power.
The space requirement is five acres in moderate sun locations. A megawatt or one million watts of energy is sufficient to power 650 residential homes for a day.

Government incentives and subsidies
The great success for solar panel installations in Australia can be attributed to several support schemes by the state and the federal government. Currently, for Australian households, three main support schemes are available. They are from:
- State government
- Federal governments and
- Electricity retailers
An overview of what’s available state-by-state is shown in the chart below:
Source: Energy matters
All small businesses and Australian households can get subsidies for solar panels from the federal government, called Small-scale Technology Certificates. The subsidy value depends on the location, but overall it brings a cost reduction of about 30%.
This is highly varied depending on the state where you live. If you live in WA, Queensland, the Northern Territory, state government incentives are not available.
On the other hand, if you are from Victoria, NSW, South Australia or the ACT, there are several state government rebates and incentives for solar and/or home batteries.
Australian Federal Government Solar Incentive
Small-scale Renewable Energy Scheme from the federal government was put in place to achieve the Renewable Energy Target of Australia. This scheme uses a mechanism known as Small-scale Technology Certificates (STCs), which reduce the upfront cost of solar PV installation.
STC can help to reduce the overall cost by 30%. This is available for anyone in Australia for systems up to 100KW.
Few points to consider:
- STCs are available to anyone who is living anywhere in Australia for installations up to 100kW.
- You do not have to apply for Small-scale Technology Certificates. They are typically applied as a point of sale discount by your solar retailer.
- Currently is no upper limit to the number of properties you can get STCs
3. Feed-in tariffs
Several states in Australia have set up schemes to promote the uptake of solar PV generation. The main idea is to promote the selling of electricity generated in the household PV systems to the grid.
In March 2009, the capital territory of Australia started a gross feed-in tariff.
- For PV systems, up to 10 kW, the payment was 50.05 cents /kWh.
- For systems that are from 10 kW to 30 kW, the payment was 40.04 /kWh.
- The payment was revised downward once before an overall capacity was reached and the scheme closed.
- Payments are made every quarter depending on the amount of energy generated.
The country of Australia is on a fast track to tap its untapped potential of solar power. With so many companies to roll out the latest and most innovative technology, the country is on a fast pace to growth.
Extensive research done in Australian universities is also helping to bring in smart technology to achieve the full potential of the sun. Along with it, several subsidies provided by the Federal and State government will help to catalyze the current growth.
