In this blog, we will explain lithium-ion solar cells, understand their costs, and discuss their advantages and disadvantages.

What is a lithium-ion solar cell?
Lithium solar batteries are a rechargeable energy storage solution that can be paired with solar systems to store excess solar energy. Lithium-ion batteries are commonly used in rechargeable electronics, such as mobile phones and electric vehicles (EV).

In 2015, the popular electric car manufacturer Tesla launched their new lithium-ion solar battery Powerwall 1, which was inspired by the technology used in its electric cars.

The launch of Powerwall 1 has triggered a lot of discussions and research on energy storage and the development of cost-effective solar cells. This has also promoted Tesla to become one of the top battery manufacturers in the United States. Powerwall paved the way for the future of lithium-ion solar cells-establishing battery energy storage pricing, promoting investment in the energy storage field, and bringing hope to battery technology. Ordinary residential customers can afford it.

Before the development of Tesla Powerwall, most solar storage systems consisted of lead-acid batteries. However, there are many lithium-ion solar cells on the market now, so every homeowner can find a choice that suits him.

However, despite the hype about this new technology, the industry and analysts have forgotten to ask a simple question. Are lithium-ion solar cells the best battery for solar panel systems?
How much does a lithium-ion solar battery cost?
Most homeowners are most concerned about the cost of energy storage systems. The total cost of installing a lithium battery energy storage system may range from US$7,000 to more than US$30,000.

Prices may vary, depending on:

What manufacturer do you choose
Features of the battery
How much battery do you need
Installation fee
The cost of installing lithium-ion batteries is much higher than the cost of installing lead-acid batteries. The installation cost of lead-acid batteries ranges from US$5,000 to a maximum of US$15,000, which is much lower than the installation cost of lithium-ion solar cells.

So why do people continue to choose lithium-ion batteries? The higher price tag brings many additional benefits that lead-acid batteries cannot get, which proves to be more costly for some people.
When is the best choice for lithium-ion solar cells?
Lithium-ion solar cells are the best solar storage system for daily residential use because they take up very little space while still storing a lot of energy. In addition, their high DoD means you can use more stored energy.

The battery life is longer, so it does not need to be replaced as often as lead-acid batteries. In addition, their higher efficiency means that you can use more energy generated and stored by solar panels-giving you value for money.

However, in some cases, other types of batteries (such as lead-acid batteries) may be more suitable for you. This is especially true if you only use solar batteries as backup power storage. Since you don’t run out of backup battery power on a regular basis, reducing DoD and life is not important, so there is no need to spend extra money on these features.

Lead-acid batteries are also popular in off-grid solar system projects that are not often used-such as holiday cottages. But for daily use, spending more money on lithium-ion solar cells may be your best choice.

Whether it is used for off-grid backup batteries or grid-connected solar systems, energy storage can help you run entirely on clean energy.
