Australia has the highest uptake of solar globally, with 20% of homes with rooftop solar PV. As at 31 October 2018 more than 1.97 million rooftop solar power systems have been installed across Australia. The process of converting sunlight into electricity using PV systems produces zero greenhouse gas emissions.
Solar PV is intended to be an investment that, once paid for, will save its owner money by generating free electricity during daylight hours. A system without batteries typically has a payback period of 3 to 5 years. Adding batteries extends the payback period by another year or two! Excess electricity can be directed into the grid, delivering a feed-in payment, or it can be stored in a rechargeable battery for later use. Batteries can also provide back-up power in the event of blackouts. solar PV and battery system offers the potential of off-grid energy self-sufficiency. It’s also a major step in the transition away from fossil fuels.
