Source: Clean Energy Council approved products lists, data as at 23 Sept 2026. Approval means a product meets the standards needed to be installed with government small-scale technology certificates (STCs). It isn't a recommendation, and Energy Quotes doesn't rank products. Check the manufacturer's datasheet and ask your installer before you buy.
