The document provides information about how solar panels work, including: 1) Solar panels convert sunlight into electricity through photovoltaic cells, with no moving parts. 2) Inverters are needed to convert the DC electricity from solar panels into AC electricity used in homes. 3) Solar panels generate electricity when demand is highest during the daytime and in hot weather.

1. How does solar work?

2. Solar Photovoltaic (PV) panels are generally fitted on the roof in a northerly direction and at an
angle to maximize the amount of sunlight that hits the panels.
Solar PV panels on the roofs of homes and businesses generate clean electricity by converting
the energy in sunlight. This conversion takes place within modules of specially fabricated
materials that make up the solar panels. It is a relatively simple process that requires no moving
parts. In most cases solar panels are connected to the mains power supply through a device
called an inverter.
Solar panels are different to solar hot water systems, which are also mounted on household rooftops but use the heat from the sun to provide hot water for household uses.
The technology to convert sunlight into electricity was developed in the 19th century, but it was
only in the second half of the 20th century that development accelerated behind the need to
provide reliable supplies of electricity in remote locations – from satellites in space to outback
Australia.
Solar panels have been installed on the rooftops of houses and other buildings in Australia since
the 1970s. Currently there are more than 100,000 solar panel systems safely and reliably
delivering clean electricity across Australia.

3. How does the inverter work?
Most suburban homes in Australia are connected to the electricity grid, which uses alternating
current electricity (AC). But the electricity generated by solar panels is direct current (DC). That
means grid-connected (GC) solar PV systems need an inverter to transform the DC electricity into
AC electricity suitable for ordinary household needs. Houses with solar systems use solar power
first before sourcing electricity from the grid.
Solar photovoltaic – how it works
Solar Photovoltaic (PV) panels on the roofs of homes and businesses capture the sun's energy to
generate electricity cleanly and quietly. Light energy is converted directly into electricity by
transferring sunlight photon energy into electrical energy. This conversion takes place within cells
of specially fabricated semiconductor crystals.
While it might be true that solar cannot generate electricity all the time, it does generate
electricity when it is needed most – during the day and on hot sunny days when electricity
demand is at its peak driven by air-conditioners.
Importantly, electricity is generated at the point of demand - where people live and work which
means there is no need to transfer the energy long distances across expensive infrastructure.

4. Greenhouse gas savings
Solar power is a zero-emission electricity source. One-megawatt hour of solar-derived electricity
avoids approximately one tone of CO2.
In Australia
Solar PV power is installed on almost 200,000 rooftops across Australia. At the end of September
2010 we had over 300 megawatts of solar PV capacity installed nationwide - an increase of
almost 10 times in less than two years.
The majority of solar PV installations are grid-connected systems. However solar PV also has a
long history of supplying reliable 'off grid' power to remote and regional Australian communities.
With the right federal policy in place providing incentives for take-up, we can ensure continued
growth of Australia's solar PV industry. The Clean Energy Council is actively advocating for a gross
metering feed in tariff that will be set high enough and for long enough to encourage increased
take-up of the technology nationwide.
Potential
As one of the sunniest continents in the world, there is massive potential for solar PV to make a
significant contribution to electricity generation in Australia. Couple this unrivalled resource with
a multitude of open spaces, and there is no reason why Australia cannot have large scale
installations generating many megawatts of electricity for sale into the grid.

7. Q-CELLS AUSTRALIA
WHY Q-CELLS AUSTRALIA? Local Support. German Engineering. Guaranteed Quality.
Q.CELLS Australia is a vibrant company that strives to continuously provide not only the best
modules, but also the best service to our customers. We do go the extra mile and consider
ourselves a partner rather than a mere module supplier. We are here to help you choose the
right system for you. If you are after something a bit different, we are here to work it out for you
– regardless of system size or geographic location.
We monitor over 30 testing sites throughout Australia, including two of our systems at the
Desert Knowledge Center in Alice Springs.
Q.CELLS was founded in 1999 in Thalheim, Germany. Within a few years we evolved into one of
the biggest solar cells producers globally. Instead of only supplying some of the best panel
producers with our high quality solar cells, we then decided to use our know-how and expertise
and to start producing solar panels ourselves. We know that only high quality modules
integrated with superior technologies can form the basis for reliable energy output.
