To find the change in annual net energy exported to the grid after BESS is installed, we, first, calculate net energy exported for a given PV system capacity without a BESS (i.e. E net0). Second, with the optimal BESS capacity, net energy exported to the grid is recorded (i.e. E netB ).
Calculate the capacity of the BESS: To calculate the capacity of the BESS, simply multiply the rated energy of the battery by the DOD: Capacity (kWh) = Rated Energy (kWh) * Depth of Discharge (%) For example, if the battery has a rated energy of 100 kWh and a DOD of 80%: Capacity (kWh) = 100 kWh * 0.80 = 80 kWh.

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.
Whilst applications of Household Energy Storage (HES) have been widely investigated and deployed, in recent years communities have been identified as a key scale for energy systems, particularly for energy storage. Community Energy Storage (CES) is therefore a promising alternative deployment model to assist the roll-out of DERs.
