Solar PV (Photovoltaic) panels on the roofs of businesses and home use energy from sun ray s to generate electricity quietly and cleanly. This conversion of this sunlight into electricity is done inside these PV cells by semiconductor crystals that are specially fabricated.

Solar panels don’t always generate electricity because the sun doesn’t shine all day. However, electricity generation happens all day, but peak generation happens during sunlight hours and hot summers when it is needed the most. This increase in power is driven mostly by air conditioning.

Another advantage of small-scale solar systems is that electricity is generated at the point where people live and work, this is the point of demand and the advantage of this is that you don’t have to transfer the electricity over a longer distance. This is common if you use solar to generate electricity at the point of supply, transferring electricity also requires expensive infrastructure to minimize energy loss.

Australia is undoubtedly one of the sunniest countries in the world. This combined with the stable policy for the environment and related things increase the potential for solar energy. This need will only continue to increase over the coming years.

Solar Generation in Australia

As of December 2019, personal solar systems up to 100kW that generate electricity at the point of demand made up 22.3 percent of the total clean energy produced in Australia. When compared to the country’s total energy production, this sector amounted to 5.3 percent.

Solar Growth in Australia

Up until now around 2.5 million homeowners enjoy the power of solar energy, through small scale rooftop solar systems.

In 2019 alone there was around 290,000 rooftop small scale installation, which was the highest number of installations after 2012. This is the 3rd highest peak in the country when it comes to solar installations. However, what is significant is the increase in the size of the solar system up to 7.62KW from the previous years. This means that the installed capacity for 2019 was 2.2GW which is around 35 percent higher than the 2018 average.

For the highest number of installations of solar panels Victoria, Western Australia and Queensland held the top three places.

Below is a quick table that summarizes the top solar areas in Australia as for December 2019

State Area Installations (in thousands) Capacity (in KW thousands)
ACT Macgregor 3.1 12
NSW Dubbo 7.3 28.7
NT Casuarina 2.5 14.7
QLD Bundaberg 14 57.1
SA Morphett Vale 5.9 20.3
TAS Launceston 3.1 13.2
VIC Hoppers Crossing 9.7 42.1
WA Mandurah 13.4 44.5

Medium-Scale Solar

After small scale systems, the next type of system was the medium-scale solar system which also had a record year in 2019. Systems between 100kW and 5MW fall into this medium category. The total capacity installed in that year was 162MW.

In the medium scale sector, there is a total of around 403MW already installed which is a whopping 700 percent increase over the past five years.

This rapid growth is due to the point of demand system on schools, hospitals and commercial buildings that switching over to green energy.

Solar energy is one of the easiest and quietest type of clean energy. The requirement will only grow and we won’t be seeing a decline in the future.
