They define two main cases: one which allows the feed in of PV power into the grid (1), and one where it is forbidden (2). While the optimal storage size for a defined household from the years 2013–2022 for case (1) varies between 3.5–6.5 kWh, the same scenario for case (2) suggests battery sizes between 3–8 kWh.

To determine the size of your off-grid system''s battery bank you want to take the Daily amp hour requirement (85.34Ah/day) and multiply this by the total number of autonomous days that you want your system to have. Please note that the more autonomous days you want to have, the larger the battery bank is going to become.

The Basic Formula. The basic formula for calculating the capacity of a battery is to multiply the voltage by the current and then by the time. The formula is as follows: Capacity = Voltage × Current × Time. Where: Capacity is the battery''s capacity in ampere-hours (Ah). Voltage is the battery''s voltage in volts (V).

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.
