Solar power is the future of energy. The cost of installing solar panels has reduced significantly over time as the manufacturers of equipment have increased in scale. With now over 3 million solar systems installed in Australia, solar panels are now an affordable investment for most homes. The Australian government also offers an upfront rebate for new solar panel installations along with some state based rebates for solar panels and batteries. The Solar Price Index has tracked the price over residential solar power in Australia since 2012. If you’re looking to save money on your electricity bill, then solar energy isn’t expensive — it’s necessary.
