The size of the solar battery you need will depend on the size of your home — specifically, how many bedrooms it has. To work out what size battery you’ll need, you can start by calculating your electricity usage. Look at either your smart meter or your monthly energy bill, which will tell you how much you use on average.
Solar battery sizing refers to the process of determining the appropriate storage capacity needed to meet your energy storage requirements and usage patterns. A well-sized battery allows you to store excess solar energy generated during the day for use at night or during power outages, ensuring a reliable and continuous power supply.
10 kW solar system with a battery — The ideal size solar battery for a 10 kWp solar panel system is 20–21 kW, as it’ll be able to make sure the battery is properly charged throughout the day. Which solar products are you interested in? What size battery do I need to go off-grid?
If you have a small panel system producing minimal power, a smaller battery would suffice. On the other hand, if your solar panels generate significant power, you’ll need a larger battery to keep the excess energy. The energy needs of every household vary depending on the number of occupants and their usage habits.
The power of a solar battery is usually measured in kilowatt-hours (kWh), which indicates how much energy it can store. Generally, in the market, you’ll find solar batteries ranging from 1 kWh to 16 kWh. But remember, a bigger battery doesn’t always mean better – your specific needs should dictate the size of your battery.
Finally, the design and configuration of your solar energy system, including the number and type of solar panels and the inverter capacity, also impact the battery size required. A well-designed system ensures that the battery can store and supply energy efficiently.

Batteries
Household batteries have a typical capacity of 4 kWh to 14 kWh; Commercial batteries can have capacity up to 100 kWh or more; Because batteries cannot be completely discharged (or emptied), the usable capacity is less than the actual capacity. For lithium-ion batteries, the difference between usable and actual capacity is small (5% to 10%).
