There are several potential cost savings – firstly, the PowerBank allows you to store your excess solar energy without having to outlay significant costs to have your own home battery (approximately $10,000 to $15,000 for similar sizes). Secondly, the conversion to a ‘time of use’ tariff. In addition to being able to recall your stored solar energy during peak periods, you will also gain access to ‘off-peak”’ pricing between 9pm and 7am each day. Energy during this period is only 15.1c per unit compared to the standard 28.8c per unit (A1 tariff).
Based on the results from the Powerbank trial in Mandurah, customers had a collective saving of approximately $11,000*.
