ABOUT
SOLAR SECURE
Solar Secure was founded with the mission to
spread solar across the rooftops of Australia
while providing an exceptional customer
experience. We have dedicated team of solar
experts and professionals across Australia.

Australia is deploying renewables at a much
faster rate than the rest of the world, even
though it has a colourful wind energy segment,
the distributed solar has the flying colours.
With an average peak sunlight hour of about 5-6
hours per day, Australia is a Sun-kissed
country. Also, top ten countries in the globe
with high GDP per capita, homeownership and
single dwelling buildings, low economic
disparity make rooftop solar just the right fit
for this country. Another major reasons that
people would be willing to adopt solar rooftop
will be low council and government approvals
which also helps in keeping the prices down
which is about AUD 1 (about 70 USD cents) per
watt in Australia.

Australia installed 107.56 MW of rooftop
capacity sprawling across the entire continent
in August 2020, thus re-amrming its stance on
renewable energy. Australia has always been very
welcoming to the changing times and with this
understanding brought in various schemes for the
population to readily handle the times as well.

The policy to source two percent of the
electricity demands of the country was in place
since 2001 which was increased to 20 in 2009.
The major reform came in January 2011, when the
policy was split into two parts

LGCs
Large Scale Generation Certificates are created
and can be claimed for systems more than a 100kW
of solar systems in Australia. They are created
for every MWh of electricity your system
generates and can be traded in the market
against the ongoing price of the LGC. The
average price of LGC stands to be around 48. To
be able to create LGCs, your system should be
accredited as per the REE act. LGCs are created
on a year on year basis.

STCs
Small scale technology certificates are for
residential solar and small businesses below
100kW of solar system in Australia. They are
issued based on how much electricity a solar
powered system will generate until 2030. One MWh
of electricity converts to one STC. For example
If your system can create 100MWh of electricity
until 2030, then based on the trading price of
STCs which varies, and can maximum go up to
40. Some areas in Australia also provide rebate
in the form of Feed-in Tariffs, where the excess
energy can be sold to the government. Feed-in
Tariffs are usually around 7-12 cents/kWh
depending on your electricity retailer.

DEEMING PERIOD
Deeming period corresponds to STCs which decline
every year from January 2017. For example, if
you install a system in 2020, your deeming period
is 11 years.

NOW, IS THAT THE ONLY REQUIREMENT TO
AVAIL DISCOUNT USING STCs ?
Government decides solar rebate using STCs
depending upon the location of the system.
Location plays an important role in electricity
generation using solar powered systems. The
amount of sunlight falling on the solar panel
varies as per the location of the solar powered
systems. Also, if the area is more prone to dust
it may have an adverse impact on the
generation. Hence, Australia is divided into
four zones as per the postcodes.

• Each Zone has its multiplier which is used to
  calculate the STC value. STCs are calculated
  based on the following parameters
• Geographic location (zone)
• Installation date deeming period
• System size in kW

as per the below formula
Number of STCs created Postcode Zone Rating X
Deeming Period Years X System Size in kW

Suppose you live in Sydney and have installed a
solar panel system of 5kW in Jan 2021. Now,
Sydney falls in Zone 3, so the number of STCs you
are eligible for would be 1.382 X 10 X 5 69
STCs
Now, considering the price per STC is 38. Total
Rebate that can be availed on the solar panel
system is 38 X 69 2622
