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.

energy storage device defined in [3]. It is defined as follows: "a generic storage device [is] any device with the ability to trans-form and store energy, and reverse the process by injecting the stored energy back into the system [while] a ideal storage device assumes certain simplifications in its technical and economic operation."
