Trial aims to help support more solar
Solar customers in South Australia and Victoria will soon be able to feed more energy into the grid thanks to a new project announced today by the Australian Renewable Energy Agency (ARENA). ARENA has announced $2.09 million in funding to a consortium led by SA Power Networks to trial a new approach to integrating rooftop solar with the grid, using smart inverters. Distributors SA Power Networks and Victorian-based AusNet Services have partnered with industry-leading inverter manufacturers, Fronius, SMA, and SolarEdge, and energy management software company SwitchDin to develop the technical capability needed to offer customers flexible rather than fixed export limits for solar. The $4.84 million project will develop and test end-to-end technical capability to enable flexible export limits for solar PV systems. The capability will be built into Australian products from market-leading inverter manufacturers and will be enabled in many other inverter brands through SwitchDin’s Droplet gateway device. Through a 12 month field trial involving about 600 customers in South Australia and Victoria, the project will test the viability of this kind of connection arrangement, and refine and develop the associated technologies and customer connection service to the point where it could be offered as a standard service to all customers installing solar. Australians are currently installing new PV systems at a rate of more than 200,000 per annum across the NEM. These systems provide many benefits but also present challenges for distribution networks in maintaining safety, quality and security of supply. Distribution networks such as South Australia’s are reaching the limit of their capacity to host rooftop solar in some areas without major investment in network upgrades. Alternatively, they may have to impose zero or very low export limits for new solar connections in congested areas. “We want more solar, not less,” said Paul Roberts, […]
