.......a
cleaner, sustainable alternative
For
many years people have been searching for a cleaner, more sustainable
alternative to the present form of electricity offered. What do
they know, that most of us don´t?
The fuels used to generate the majority of our electricity are
coal dug out of the ground, gas taken from off shore deposits
or water from dams to create hydro electricity. All of these methods
of generation have significant impact on our land, our society,
and are hardly sustainable in the long term. It´s worth
noting that for every 1000 watts per hour (kwh) of electricity
generated through the use of brown coal, we produce approximately
1.4kg of greenhouse gases. An average home may use between 10
and 20 kWh of electricity per day. Think about how many homes
there are in your suburb or city, and you will begin to see the
environmental cost of these types of electricity is significant.
Australia´s emissions of greenhouse gases are amongst the
highest per person of any country in the world, a quarter of the
countries CO2 emissions come from the generation of electricity
from coal.
Not only is coal and gas-driven electricity production environmentally
damaging, these products are in finite supply. We cannot be sure
how long they will last at the rate they are currently consumed.
Another issue with the electricity supply that reaches a large
majority of the population is that the electricity grid is often
unreliable or has insufficient capacity.
But there is one energy source we can rely on long-term - the
sun.
Now,
thanks to Solar Energy Australia, technology has advanced significantly
enough to allow us to utilise the sun´s power to help enhance
the traditional method of power generation.

Solar
Energy Australia can now offer you a Solar Grid Feeding System.
A Solar Grid Feeding system is simple yet elegant, it can blend
into almost any building and its performance is seamless. Solar
Panels convert sunlight into DC electricity, this DC electricity
is then fed into a Solar Energy Australia Grid Feeding Inverter,
which feeds this power onto the electricity grid via your home.
(The diagram illustrates this process).
Most
electricity retailers are pleased to accept clean, sustainable power
from your Solar Grid feeding system, ask your electricity supplier
about their Green Power policy.
Metering
Two methods of electricity metering are usually acceptable; nett
metering, where only one electricity meter is required, (usually
the older moving disc type). This meter will run backwards if your
solar grid feeding system is producing more power than your building
is using, effectively selling power to the electricity retailer
for the same price at which you buy it. At night when the sun goes
down or in times of overcast weather, your meter will run normally
as you draw power from the electricity grid.
Two way metering requires the installation of a second meter or
an electronic meter, which can read power going in both directions.
You can then negotiate with your electricity retailer the price
that they will pay you for your electricity.
Investments
for the future
A solar grid feeding system will add significant value to your home,
once your initial capital investment is made, there is minimal maintenance
required. As the cost of mains electricity increases, your investment
will also increase in value, year after year after year. There is
no doubt, that in years to come, a building which is energy efficient
and therefore cheaper to run will attract more interest from potential
buyers than an old fashioned inefficient building with no Solar
Grid Feed System.
But
its not just a financial investment, but an investment in a cleaner
environment. Depending on your climate, a typical 1500 watt system
can produce 5-8kwh per day, saving around 3.5 tonnes of greenhouse
gasses per year, and still have room to expand.
Experiences
Solar Energy Australia are not new to Solar Grid Feeding systems,
our grid feeding inverters were amongst the first available in the
world and have been installed in many countries, and are in use
in some very high profile sights in Australia including:
- 200kw installed at the Singleton Solar Farm north of Sydney
- 70kw installed at the Sydney Superdome
- 60kw installed on schools throughout NSW as part of SEDA´s
PV in schools program
- numerous homes throughout Australia.
