How to decide on a battery to your solar energy system

Using a solar battery is one of the best ways to store the energy produced by your solar power system. If your system is producing more energy than you need to power your home, you can store that energy in a solar battery for later use. Once you have decided to install a solar battery, you need to know how to choose a battery for your solar power system. This article covers the basic factors that you need to consider when choosing a solar battery.

Factors to Consider for Solar Power Batteries

Battery capacity

The capacity of a battery indicates how much electricity the solar battery can store at one time. Capacity is measured in kilowatt hours (kWh) and multiple batteries can be used at the same time for greater capacity.

Battery power

Performance and capacity go hand in hand. While the capacity of a battery indicates how much energy it can store at one time, the performance of a battery indicates how much of this energy it can use at one time. The performance of a battery determines how much electricity it can provide for your home in a given period of time.

Depth of discharge

Depth of Discharge is the capacity of a battery that you are using. To extend the life of a battery, a battery should not be completely discharged, so it is important to consider the depth of discharge of your solar battery. Buying a battery with a higher depth of discharge will allow you to make better use of the capacity of your battery before you need to charge it.

Round trip efficiency

The round trip efficiency of a battery is the amount of energy that can be used of the total energy to charge it. Batteries with higher round trip efficiency are generally more economical.


Once you've considered these characteristics of a potential battery, be sure to check out the warranty. A battery warranty gives you an idea of ​​how many years or cycles the battery should last before it needs to be replaced. A warranty also tells you how much you can expect a battery's performance to deteriorate over time.
