Our client’s journey to a clean, green energy future started with an electric car.
Tony installed solar PV to provide the power needed to charge the car, heat water, cover the house load and export back to the grid.
But when he added batteries, pay-back changed dramatically. Now Tony estimates the pay-back time has reduced from around 8 to 5 years.
Not only can the batteries store excess power, for use in the evenings, they can also store imported power overnight. On the Intelligent Octopus Go tariff electricity costs 7.5p/kWh over a 6-hour window, while exporting during the day is 15p/kWh.
