The rate of uptake of rooftop solar and battery technologies has been rapid but mixed according to location and product type. This presentation explores the key drivers for growth in adoption. They include technology costs, electricity prices and tariff structures, subsidies and a wide range of non-financial factors which vary depending on the customer type. Consumer technology adoption curves are relevant for categorising and predicting consumer adoption behaviour. As the strength of the various drivers change over time, we can draw several conclusions about the expected rate of adoption going forward.
