6 Reasons Why Lithium Ion Batteries are Good for Solar

lithium ion solar batteries

Lithium-ion batteries are available in a variety of configurations and have a wide range of applications. This means that some lithium-ion batteries on the market today are better suited to specific applications than others. The critical point is to select the battery that is most appropriate for the work at hand.

Solar panels have become increasingly popular due to factors such as soaring energy costs, the low maintenance cost of solar panels, and a one-time investment model. But one major concern for solar advocates is that the sun is not always shining and how to store energy when the sun is shining for later use. Luckily, new energy technologies have come up to answer this problem which will help homeowners to power their homes all day long. Lithium-ion solar batteries are one of the best ways to store solar energy. In this blog, we are going to discuss 5 reasons why lithium ion batteries are good for solar.

Higher Depth of Discharge (DoD)

The DoD of a battery is the amount of stored energy that has been consumed. In order to keep the battery healthy, most batteries come with a recommended DoD. Deep cycle batteries, such as solar lithium ion batteries, have DoDs of around 95%. Several lead-acid batteries only have a DoD of 50%. This implies you can take advantage of more of the energy stored in solar lithium-ion batteries without having to charge them as often.


The long life span of lithium ion batteries is high DoD and not having to charge often. Most lithium ion solar batteries are warrantied for a least 10 years, or 10,000 cycles, whichever comes first in terms of life expectancy. On the other hand, lead-acid batteries carry a 5-year warranty. Lithium-ion batteries’ improved longevity helps you recoup the money you’ve spent on them much faster.

Higher energy density

A battery’s energy density measures how much power it can store in relation to its actual physical size. Lead-acid batteries take up a lot of room, whereas lithium ion batteries can store more power without occupying as much space.

Charging is simple and fast

Solar lithium ion batteries that charge quickly mean reduced downtime for equipment that is tied to a charging station. Of course, in an active facility, the less time equipment has to stand motionless, the better. A device’s lithium-ion battery may be able to be charged while it is plugged in, further reducing downtime. There is no longer a need to design cleaning procedures around the need for a battery to fully charge in between uses, which means that training for staff members may be simplified as a result.

High Performance

The round-trip efficiency of lithium ion deep cycle batteries for solar is higher than that of other types of solar panels. The amount of useable energy you leave in your battery relative to the amount of energy it takes to maintain it is known as performance. The efficiency of lithium ion deep cycle solar batteries ranges from 90% to 95%.

Impact on the environment

In comparison to other nonrenewable fuel sources, lithium ion battery solar storage offers substantial environmental advantages. Electric vehicles have been steadily increasing, and we are seeing an immediate reduction in carbon emissions. In addition to saving money in the long run, reducing the number of gas-powered cleaning machines you use makes your service more environmentally friendly.

When to use a lithium ion solar battery?
As a result of their small size and high energy storage capacity, lithium ion solar batteries represent the ideal option for everyday household use of solar energy storage. Also, because of their high DoD, you’ll be able to use more of the saved energy. There is no need to replace it as frequently as with a lead acid battery. You receive greater value for your money because of their increased efficiency, which means you can use more of the energy your solar panels generate and store. However, lead acid batteries, for example, maybe better suited to your needs. This is especially true if your solar battery is only being used as a backup power source. Spending the extra money on features like lower DoD and longer lifespan is unnecessary because you won’t be draining a backup battery on a regular basis.
Do I need a special solar charge controller for a lithium-ion battery pack, (same voltage as a regular lead-acid battery)?
To ensure that your lithium batteries are not overcharged or discharged, a BMS is required. The BMS will regulate and cut the solar charger’s current as soon as it detects that your batteries have reached the proper voltage, ensuring that your lithium batteries are kept safe. Because DC is DC, you can use a lead acid battery solar charge controller for lithium batteries.
How do I charge a lithium ion battery with solar cells?
You don’t need to worry about it. A battery bank is used to store the electricity generated by solar panels. The battery bank in question is what generates the electricity that powers most of the average American home. You connect your lithium battery charger to a household electrical outlet that is indirectly powered by your solar system and then charge your batteries. What you do not do is hook up a solar panel directly to any battery charger.
