Discover how to choose the right battery size for your solar energy system in this comprehensive guide. Explore key factors like battery capacity, depth of discharge, and voltage, as well as the differences between lead-acid and lithium-ion batteries.
Your first step in figuring out “what size solar battery do I need” is to estimate your home's daily power consumption, measured in kWh. Look at your electricity bill to find out your household's monthly consumption. Divide this number by the days in the month to get a daily average.
Suppose you consume 30 kWh daily. If you choose a lithium-ion battery with a usable capacity of 10 kWh and a DoD of 90%, you'll need at least three batteries to meet your daily needs. By understanding these components, you'll be equipped to choose the right size battery for your solar energy system, ensuring seamless and efficient operation.
The most common voltages for solar batteries are 12V, 24V, and 48V. Picking a battery voltage (aka system voltage) has lots of downstream effects on the size of your charge controller, solar array, and wiring. Give this step the time it deserves. 1. Watch this video from Explorist Life.
To size your solar battery system effectively, follow these steps: Calculate Daily Energy Needs: Review your electricity bill or use an energy calculator. Assess Peak Usage: Identify periods when your energy demand is highest.
By analysing how much energy you use and when you use it, you can select a battery that can store enough energy to meet your needs, ensuring that your solar energy system operates efficiently and effectively. The desired level of energy independence is another crucial factor.
For example, if you have a 10 kWh backup battery you may also be able to use it for solar self-consumption (with the understanding that you won't get much or any backup power if the grid goes down shortly after your battery has been discharged). So, let's say your primary goal is to power critical systems during grid outages.
For a 20kW system, you typically need 60-80 panels, depending on the wattage of each panel.

According to the Battery University, a 2000 mAh alkaline AA battery contains approximately 10. 4 watt-hours, translating to roughly 39,000 to 51,840 joules of energy.
One mAh battery can deliver a continuous current of one milliampere for one hour. For example, if you have a smartphone with 2000mAh. Once fully charged, the battery can hold 2000mA. If the phone draws around 200mA per hour, it should be able to run for 10 hours.
A higher value indicates a greater ability to hold energy. For example, a battery with a capacity of 10,000 mAh can typically power a device that draws 1,000 mA for approximately 10 hours. The choice of capacity depends largely on the intended usage and the power needs of the device.
Capacity requirements: Each device has specific battery capacity needs measured in milliamp hours (mAh) or watt-hours (Wh). A smartphone may have a battery capacity of around 3000-4000 mAh, while tablets can range from 5000 to 10000 mAh. In contrast, a laptop might require a battery with a capacity exceeding 30000 mAh for a full day of usage.
Standard smartphone, tablet, and portable batteries hold 5,000 mAh of power. This rating suggests the battery delivers 5,000 milliamperes of current for one hour before recharging. A 5,000mAh battery powers a typical smartphone for a day of moderate use, including browsing the web, checking emails, and watching videos.
2,000mAh Battery: This capacity is typically found in older smartphones or small devices. For a smartphone with moderate use (calls, texts, light browsing), a 2,000 mAh battery might last 6-8 hours. For heavier use, such as gaming or video streaming, it may last 3-4 hours.
That said, a battery rated at 40,000 mAh can power a device that withdraws 400 milliamps for 10 hours. Now that you know what is mAh, let us understand the importance of mAh and how it differs from charge capacity in the following sections. mAh is the most critical factor you'll need to consider when choosing any battery-powered device.
