Battery storage system capacity should be appropriate to meet residential consumption demand. Basicly, the storage system should be large enough to supply a household with solar power all through the night. A battery capacity of 100Ah to 200Ah at 51.2v is usually sufficient for an average four-person home consuming around 3000 kilowatt-hours (kWh) …

Solar panels for households typically come in the standard dimensions of 1.70m x 1.00m, that''s around 1.7m2 for every panel installed. However, the wattage output (W) of the panels will likely vary between 360W and 415W for a more efficient module. As a guide, you''ll need 14 x 360W panels, or 12 x 415W panels for a 5kW system, the modules ...

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.
