Solar Batteries

What Do You Need to Know About Solar Batteries?

Are you looking to buy a new solar system? Then, you can not overlook the importance of solar batteries. They are an integral part of the entire system and can make a huge difference in the overall efficiency and effectiveness.

Which types of solar batteries are available in the market? Let’s find out in this comprehensive guide!

Why Do You Need Solar Batteries?

Solar batteries store the energy consumed by solar panels. As a result, the system works effectively even without sunlight. Otherwise, your system will only power the connected household during the daytime. However, batteries make the framework more efficient by conserving power for when you need it.

A frequently asked question is, how do solar batteries work? In short, a solar battery hosts different chemical reactions that lead to energy conservation. It makes room for surplus electrical energy, allowing you to keep your house well-lit during the evening and night. Check how to measure a battery.

Types Of Solar Batteries

Generally, you will find two types of solar batteries, including the following:

  • Lithium batteries
  • Li-ion batteries

Many people confuse them because of their similar names. Although they might have some similarities, they differ drastically.  Let’s discuss both batteries in detail to provide a clearer picture:

1.   Lithium Batteries

Lithium is the lightest metal on earth. Hence, this battery utilizes this metal to create a rechargeable power option. It leverages metallic lithium as an anode material, using processes like intercalation and deintercalation. In simple words, this battery works with a positive electrode material and a negative one.

Lithium batteries cannot be charged and have a higher cost per unit. Additionally, they possess a higher charge per density, being more capable and durable. These batteries have become famous for their utilization in electric vehicles.

A lithium battery can produce between 1.5 to 3.7 V of electricity. Even though it is common among households, it is not the best option. It can cause environmental damage due to its highly reactive nature.

2.   Li-Ion Batteries

A lithium-ion, or li-ion, battery also uses lithium as its anode metal. However, its electrodes are made of carbon and lithium. As a result, they are even more lightweight than a lithium battery.

One significant plus point is that you can recharge and reuse them. These options are not available in a lithium battery. That’s because this type is used as a secondary cell. Generally, lithium-ion batteries are used in small-scale electronics, like cameras and mobile phones.

The prime benefit of a lithium-ion battery is its higher efficiency. However, its sophisticated structure and circuiting can be expensive. This battery has a more complex build than a traditional lithium battery. On the bright side, it is significantly more durable. You can recharge this battery dozens of times before it fails.

Difference between Lithium and Lithium-Ion Batteries

The first and foremost difference between the two is their construction. A lithium-ion battery has a secondary cell construction, while lithium batteries have a single-cell primary build. And that also leads to the most prominent difference. Lithium batteries are non-rechargeable. Alternatively, lithium-ion batteries are rechargeable and reusable.

The shelf life of lithium batteries is longer, going as long as 12 years. On the other hand, a lithium-ion battery will only survive a maximum of 3-year lifespan. But this factor can be reversed when both batteries are in use. In that case, a lithium battery will run out of its power quicker, whereas a li-ion battery can recharge hundreds of times.

Other Solar Batteries You Should Know

A lithium and li-ion battery is not the only option you have. You can also find some other types, including the following:

  • Lead-Acid: Commonly used in automotive, a lead-acid battery has lower energy density but offers a more cost-effective solution for home solar systems.
  • Nickel-Cadmium: A nickel-cadmium battery has industrial and commercial applications, operating at higher temperatures with increased durability.
  • Flow: Powered by chemical reactions, this battery contains electrolytes within its chambers to produce and store energy with a lower energy density.

How Much Do Solar Batteries Cost?

The costs of the solar battery can vary with its type. Generally, lithium-ion and lithium are the most preferred option in households. These batteries can cost anywhere between $7,000 to $14,000. The factors affecting their price include the system’s size, battery capability, and brand.


Now, you know the differences between lithium and lithium-ion batteries. Hopefully, you can now also make an informed decision on which type is more suitable for your needs. It is best to review your considerations, requirements, and budget limitations before choosing an option. Durable and capable solar batteries that don’t harm the environment should be your priority! you can order the best one’s from stg nations.
