As Australia receives some of the most sunshine globally, more than 20% of Australian homes are now powered by the sun, and this number continues to grow. Renewable energy solar options significantly reduce your household electricity bills, often by up to 80%, and offer an alternative to buying our power from the grid. Once a solar system is installed on your roof, it will continue to generate free electricity from the sun year after year. With the introduction of batteries, it is possible to gain almost complete energy independence from the grid.
