Solar batteries are a cost-efficient investment for energy storage. It is impossible to store energy generated by your solar system without a battery bank. If it is connected to the grid, there will be no backup power if the utility grid suffers an outage. In terms of off-grid, your system will not be working at all. It’s important to have batteries to keep your system running. There are many factors that need to be considered when choosing the best lithium batteries for your solar panels, such as power, efficiency, costs, and battery capacity. Let’s help you make the right choice by reviewing how solar batteries work.
It is recommended to store excess solar energy instead of letting it go back to the power grid if you have a solar battery installed as a part of your solar panel system. If more electricity is produced than needed by your panels, your battery can be recharged by this energy. You can draw from the stored energy in case there is no electricity produced by your solar panels. The electricity will be drawn from the grid when the battery is low, and it will be sent back to the grid when the battery is full. Electrical grid can also use energy from solar storage inverter which converts direct current (DC) electricity, which is what a solar panel generates, to alternating current (AC) electricity
It is essential to compare lithium batteries for solar panel storage based on the depth of discharge (DoD), capacity, battery life & warranty, and round-trip efficiency when you consider solar battery options. 48 volt batteries are mostly been used in solar systems. However, it’s also important to consider what batteries work best with your system’s requirements. Now let’s break down each factor:
1. Depth of discharge (DoD): The amount of battery that’s used is indicated as the depth of discharge. You will get more usage from the battery's capacity if the DoD is higher. Generally, the depth of discharge should be more than 40%.
2. Capacity: The total amount of electricity stored in a solar battery is called capacity. It is measured in kilowatt-hours (kWh).
3. Battery life & warranty: It is inevitable that battery performance will decline over time, However, there is no need to worry if you have a warranty that guarantees good performance and maintains a certain capacity.
4. Round-trip efficiency: The difference between the available amount of energy and the amount of energy to charge it is defined as round-trip efficiency. Generally, a high round-trip efficiency is more economical, and it’s recommended to have a round-trip efficiency of around 80%.
