REC calculator
In addition to the generous cash rebates for purchasing entire systems, you can earn renewable energy credits (RECs) from the federal government by purchasing and installing solar hot water collectors. This calculator uses the information publicly available for download from www.rec-registry.gov.au
Enter your postcode and the brand of the solar hot water you intend to buy. The REC zone you live in will be displayed, along with a table showing all models of the selected brand. Read the highlighted column for your model and this is the number of RECs earned by your model.
