The developments of battery storage technology together with photovoltaic (PV) roof-top systems might lead to far-reaching changes in the electricity demand structures and flexibility of households. The implications are supposed to affect the generation mix of utilities, distribution grid utilization, and electricity price.
In this scenario, a household with an annual export energy of about 2000 kWh would get a payback period of about 5 years with a 2 kWh storage system, 6–7 years with a 4 kWh storage system, and 6–10 years with a 6 kWh storage system. Payback period is generally higher for households with low export energy. Fig. 11.
