Solar credits Wikipedia
Solar credits are an initiative of the Australian Federal Government used as a multiplier to increase the number of Small-scale Technology Certificates (STC's) able to be created for eligible solar panel, wind and hydro energy systems.
Solar credits apply to Small Generation Units and create multiple Small-scale Technology Certificates for the eligible part of their capacity. This applies to the first 1.5 kilowatts (kW) for eligible mains connected systems. Off-grid systems may be eligible for Solar Credits for the first 20 kW if an annual capacity limit is not reached.
