What is a Solar PV system?
Photovoltaic (often abbreviated as “PV”) is a scientific term used in the solar power industry to describe
the process and effect that the sun’s rays have with your solar panels to create electricity.
Your solar panels are made of individual cells with negatively-charged and positively-charged wafers.
When light hits the cells, it energizes electrons from the negatively-charged wafers that flow as an electrical current
through the conductor to the positively-charged wafers. This current can then be used to power loads that are connected
to this conductor.
What is the difference between Monocrystalline and Polycrystalline solar panels?
Monocrystalline vs Polycrystalline (or ‘multicrystalline’) solar panels. Although monocrystalline
panels had the initial advantage of being seen as the superior technology in the Australian market, as time goes on and
both technologies improve, it becomes increasingly apparent that the the quality and reliability of the manufacturer is
far more important than which of the two technologies is chosen.
Typically Monocrystalline solar cell is a dark black colour, and the corners of cells are usually
missing as a result of the production process and the physical nature of monocrystalline silicon.
Polycrystalline, on the other hand, is identifieable by its signature light or dark blue colour,
but not uniformly so: some patches are lighter than others. The differences in appearance come about as a result of the

How much does a solar system cost?
The price of solar systems has dropped dramatically over the past few years, making it an increasingly attractive option
for homes and businesses.
The upfront cost of your solar PV system is affected by a number of different factors, including:
As a very rough guide, the total cost of getting a home solar system up and running is
between $2500 (for a small 1.5 kW system) and $11,500 (for a top-of-the-line 5 kW system).
For businesses, the approximate cost of installing solar ranges from around $15,000
(for a 10kW system) to more than $200,000 (for a high-capacity 100 kW system).
How much money will I save with Solar Panels?
The amount of money your household will save on power bills by going solar
is affected by a number of factors, including:
Businesses have a couple of other things to take into account, including the
tax implications of any revenue received from feed-in tariffs.
Are German manufactured panels and inverters better than ones manufactured
No, many world-class panels and inverters are now manufactured in Asia, just like
components and technology for other industries. As technology gets better around the world, any tech giants
of today source their manufacturing from all parts of Asia. Many of the parts for Apple products are
sourced from different parts of Asia.
How can I check if my panels and inverter are approved by the
Clean Energy Council?
The Clean energy council keeps a list of approved solar modules and inverters
and it can be accessed at
What does the inverter do?
An inverter converts the DC electricity generated by your solar panels into
AC electricity that can be used in your home and fed back into the electricity grid.
What is a solar feed-in-tariff?
A feed-in-tariff is the amount your electricity retailer pays you for any
electricity your solar PV system generates that you don’t use, and is instead fed back into
