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.
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?
Several key factors influence the battery size you require: Assess your overall electricity usage by examining your utility bills. Understanding daily usage helps you estimate the appropriate battery capacity. Evaluate how much energy your solar panels generate.
For a solar photovoltaic (PV) system of 5 kW with a daily energy consumption of 5-10 kWh, a 4 kWh battery is recommended to maximize returns, while a 35 kWh battery is advised for those looking to maximize energy independence.
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. Then, divide by thirty to get a rough estimation of your daily energy use, and you’ll be able to work out what size battery is best for you.
As a rule of thumb, 10 kWh of battery storage paired with a solar system sized to 100% of the home’s annual electricity consumption can power essential electricity systems for three days. You can get a sense of how much battery capacity you need by establishing goals, calculating your load size, and multiplying it by your desired days of autonomy.
