Australia is committed to its Renewable Energy Target (RET) of 20% by 2020. An abundance of sunshine is a unique natural advantage that Australia enjoys. This abundance of sunshine can be harvested and used as a renewable energy source such as solar photovoltaic. More than 10% of Australian homes are currently being powered by solar energy. This number grows on a daily basis because solar power has become an important alternative to purchasing conventional electricity from the grid. Solar energy, at this point, may not completely remove our reliance on the grid, but it can greatly replace a large amount of the energy we have purchased from the grid in the past.
