Solar Battery – Price, Types, Technology & A Complete Guide

A solar battery is an energy storage device that can be paired with an off-grid and hybrid solar system. It is also known as a solar panel battery, solar power battery, or solar battery storage. Solar batteries are designed to connect with a solar charger controller or solar inverter to provide power backup.

These next generation batteries will change the way you use solar power. You can use a solar battery to store the extra power generated by your solar panels throughout the day and use it later as needed.

Installing a solar battery at your home allows you to use more solar power at home while using less grid power. Once your battery is fully charged, your solar system will transmit power to the grid. If your grid electricity goes out frequently and you need backup power, solar storage options are worth considering.

Solar batteries are available in a variety of sizes and capacities on the market. So it is worthwhile to spend 10 minutes reading the complete information provided below in order to select the best one for your home.

#2. 2 Types of Solar Battery

When it comes to the different types of solar batteries, there are primarily two types. For decades, these batteries have been used in the solar industry. Take a look at these batteries if you are thinking about installing a solar system or adding batteries to an existing solar system.

Tall Tubular Solar Battery (Lead Acid)

Lithium-ion Solar Battery (LiFePO4)

Let’s take a deeper look at these 2 types of solar batteries.

#3. Tall Tubular Solar Battery

A lead-acid tall tubular battery is the most successful, oldest, and reliable solar battery technology. It is an improved version of standard batteries that can be used with solar panels at home.

These solar batteries are C-10 rated batteries, specially designed to meet the needs of all solar applications.

A lead-acid tall tubular battery requires to top-up with water every 3 to 6 months and can store more power than any other battery.

Solar tubular batteries are deep cycle solar batteries that have been thoroughly tested and can be used in off-grid solar systems, hybrid solar systems, and solar home lighting systems.

Pros & Cons of Tall Tubular Solar Battery

  • Advantages
  • High-efficiency batteries
  • More than 1500 life cycles
  • 5 to 7 years long working life
  • Cost-effective solar product
  • Easy to maintain, install, and access.
  • No need of heavy maintenance
  • Very low repair/maintenance cost
  • Disadvantages
  • Tall tubular batteries are heavy
  • You need to refill these batteries timely
  • More space is required compared to lithium-ion batteries

#4. Lithium-ion Solar Battery

Lithium-ion is another popular type of solar battery, well known for its high current rating, and long cycle life. The most significant advantage of lithium-ion batteries is their extremely long life-cycle (up to 5000 cycles) and high charge and discharge capabilities, which allows you to harvest more energy from your solar panel.

The lithium iron phosphate (LiFePO4) battery is the best type of lithium-ion battery for your solar power application. LiFePO4 batteries are completely safe, non-flammable, stable for 15 to 20 years, and require no maintenance.

It also has good electrical performance and a low resistance. For these reasons, lithium-ion batteries are an excellent choice for a wide range of solar applications, including all-in-one solar street lights and solar-powered vehicles.

  • More than 5000 life cycles
  • Higher energy density
  • More efficient than Lead-Acid batteries
  • Do not require maintenance
  • Eco-friendly solar batteries
  • Disadvantages
  • Comparatively more expensive

#5. Solar V/s Normal Battery

Solar battery is a good substitute for the normal battery because it is not only an environmentally friendly option, but it also has the potential to last longer than traditional batteries.

  • A normal battery stores power in chemical reactions, which can degrade over time and with use.
  • Solar batteries store power by converting sunlight into electricity, which means they are not subject to the same limitations as a normal battery.

#6. Features of Solar Battery

The popularity of solar batteries has been increasing for the last few years as a way to fulfill the world’s growing clean energy demand. These batteries have been specifically designed for used in high-performance solar system. Let’s take a closer look at these features.

  • Excellent Efficiency

    The overall success of a solar system depends on storage efficiency. Therefore, solar batteries have an excellent efficiency level. A solar battery maximizes the use of your solar panel system and increases your energy independence.

  • Superior Life Cycle

    The expected life of a solar battery is very long. Furthermore, depending on the type of solar battery, they have an extremely long life cycle. Lead-acid tall tubular batteries have a life cycle of 1500 cycles, whereas lithium-ion batteries have a life cycle of up to 5000 cycles.

  • High Round Trip Efficiency

    Solar batteries have high round trip efficiency. This means that the power loss during transmission will be very less and you will be able to use most of the stored electricity.

  • Tuff Futuristic Design

    Solar batteries are made of highly-quality materials and have a very premium appearance. They are robust and suitable for off-grid and hybrid solar systems. You can install them anywhere in your home.

  • Water Level Indicators

    One of the unique features of solar batteries is that they include water level indicators. Water level indicators will tell you how much water is left in your battery and when it is time to recharge it.

  • Ultra-Low Maintenance

    Solar batteries require very little maintenance. These batteries require to be top-up with water every 3 to 6 months. There is no additional repairing or maintenance cost for these batteries.

5 Tips To Choose Best Solar Battery For Home

If you are looking for a solar battery for your home then the first thing you need to learn is how to choose the best one. Below are some important points that you should consider while choosing the best solar battery for your home.

Do you know the best capacity solar battery?

The capacity/rating of a solar battery indicates how much power the battery can provide. Usually, the capacity of a battery is measured in Ah (ampere-hour). The higher the energy capacity the more electricity is available for use and the longer you can run appliances on battery life. For domestic purposes, we suggest you go for a 150Ah capacity battery.

Will your solar brand be with you for a long time?

The brand of a solar battery is one of the factors that affect most people psychologically. Many solar brands make many promises to you while selling their solar product, but they do not listen to you after the product malfunctions. So be careful and only go for trusted brands like UTL Solar, Luminous Solar, Exide Solar, etc.

Did you ever hear about “Round-Trip Efficiency”?

You may not hear the term “Round-Trip Efficiency“ but it plays an important role to decide whether a solar battery is best for your home or not. Any battery’s round trip efficiency represents the percentage of stored electricity that can eventually be used. And the rest of the power is lost during transmission. So always choose a solar battery with at least 80% round-trip efficiency.

Know about the battery’s depth of discharge.

The depth of discharge of a solar battery shows what percentage or capacity can be discharged from a fully charged battery. For example, if you have 5kWh solar system and battery with a maximum DoD of 80%, you should not utilize more than 4kWh power without recharging the battery again. So it’s obvious, you should go for a higher DoD battery.

Have you compared the working life and warranty of solar batteries?

Estimated years of operation, expected throughput, and expected cycles are three metrics, used to calculate battery life. Throughput tells you how much electricity you will get through your battery over its lifetime. On the other hand, cycles tell you how many times you can charge and discharge a battery. Always go for a battery with high throughput, more expected cycles, and a longer warranty.
