What Types of Solar Batteries are Available in Australia? 

There are several solar battery types that you can purchase and install in your home. The right one depends on your solar battery setup, its requirements and specifications, and your requirements and preferences.

Lead acid solar batteries are classics and are generally dependable. However, their old technology is now surpassed by newer, better, high-tech, cheaper solar battery types.

Lithium-ion solar batteries are popular units for both household and commercial use. First used in the electric car industry, these batteries are designed to prioritise power or energy density.

Flow batteries act and function like fuel cells. Their advantages include independent scaling of power, longer cycles and calendar life, and lower cost. However, they also suffer from inferior cycle energy efficiency compared to lithium-ion batteries.

Sodium nickel chloride batteries, sometimes called molten salt batteries, offer high energy and power density. They are expensive and usually impractical for standard residential and commercial use. However, they’re widely used for special electric vehicles, industrial power backup systems, and military applications.

Let’s find out more about these battery types and how these solar batteries work

Lead-Acid Solar Batteries 

A lead-acid solar battery is one of the most common rechargeable batteries. It uses lead and sulfuric acid chemical reactions to produce electricity, charge, and discharge. 

A lead peroxide plate and sponge lead plate are immersed in dilute sulfuric acid; this creates a controlled chemical reaction that allows the battery to generate electricity. The process is reversed to recharge the battery.

Lead-acid batteries are typically used in vehicles, but specialised lead-acid batteries designed for solar power are also available. You usually need a bank of these batteries, ideally set up in a cool, climate-controlled shed; high temperatures can decrease their lifespan and efficiency.

Although somewhat overshadowed by new lithium-ion batteries, lead acid batteries are still in demand because they’re affordable and are a tried and tested technology. They’re popular for people who wish to live off-grid or have limited-to-no-grid access.

Lithium-ion Solar Batteries 

In a lithium-ion solar battery, lithium ions stored in cells move from the negative electrode to the positive electrode via an electrolyte to charge the battery. The flow is reversed when the battery is charged. 

An intercalated lithium-ion compound is used for the positive electrode and graphite for the positive electrode.

Many installers prefer lithium-ion batteries due to their low self-discharge, better energy density, and absence of memory effect. However, they can be hazardous, considering they have flammable electrolytes. Care must be exercised because improper usage or damage can cause the battery to explode or catch fire.

Flow Solar Batteries 

A flow battery is a form of electrochemical cell. Two chemical components are dissolved in liquids which are then pumped through the cell, passing through a membrane. As both liquids circulate, chemical energy transfers through the membrane, together with an electric current generated through an external circuit.

Solid electroactive materials give the battery several advantages over its counterparts. For example, a flow battery’s power can be scaled independently through the size of the battery stack. It may last longer and has longer cycles.

However, flow batteries have lower cycle energy efficiency than lithium-ion batteries, so need to be operated at high current densities to reduce power costs.

Sodium Nickel Chloride Solar Batteries 

A sodium nickel chloride battery utilises sodium chloride as its cathode and sodium as its anode. It operates on the principle of electrochemical reactions entailing the flow of sodium ions between the positive and negative electrodes. 

The electrodes are isolated via a beta-alumina electrolyte; this electrolyte conducts sodium particles but not electrons.

Operating at a temperature range of 270°C to 350°C, sodium nickel chloride batteries are considered a high-temperature energy storage gadget. As such, they’re often used for military applications, as balancers for wind turbines and solar panels, and other industrial-scale applications.

How Do I Choose the Right Solar Battery Storage for my Home? 

Choosing the right solar battery storage system for your home requires you to consider the amount of energy your household uses, the current solar panel system you have and the solar professional you work with. 

What is the best solar battery for your home? This list will give you insight into the considerations for selecting the right battery for you. Of course, a professional installer can iron out the details that will help you choose.

Battery Capacity 

Calculate your home’s peak power requirements using amp hours; this is important in choosing the right battery with enough storage for your needs. For example, a battery rated for 100 amp hours can produce 1 amp of electricity for 100 hours. 

Lifespan and Charge/ Discharge Cycles

Your battery’s longevity depends on its charge and discharge cycles. In general, the more charge/discharge cycles your battery has, the longer it lasts. Two factors should be evaluated in this aspect:

Flooded vs Sealed Batteries 

Flooded batteries – such as lead-acid batteries in off-grid solar systems – utilise liquid media that contains electrolytes to activate an electrochemical reaction.

Sealed batteries – such as lithium-ion solar batteries – are rechargeable batteries that do not contain liquids or hold a minimum amount of liquid to enable the flow of electrolytes. They are often sealed in a casing and are maintenance-free.

Peak Power Output 

The peak power output, often determined by kilowatt peak (kWp), refers to the highest level of power the battery can produce at its optimal performance. The higher the kWp rating, the more efficient the battery is.

Round-Trip Efficiency 

A solar battery’s round-trip efficiency refers to the percentage of electric energy stored in the unit, which can be retrieved when needed. Less energy is lost in storage if the round-trip efficiency rating is higher.

Brand and Warranty 

Battery manufacturers boast of the capabilities, features, and advantages of their solar battery lines, offered warranties, and their after-sales service. These should also be considered when choosing the right battery for you.

Note that these are just general considerations. You need a professional battery installer to help with solar battery comparisons and choices.

Related Questions

What Is the Lifespan of a Solar Battery?

Home solar battery brands can last around 5 and 15 years, although your solar system can last up to 20 or 30 years. But the lifespan of a solar battery depends on the number of its charge and discharge cycles. That means you will replace your batteries at least once to match your solar system’s lifespan.

What Voltage Should My Solar Battery Be? 

It varies, depending on the requirements and specifications of your existing solar system. Solar batteries are available in 6V, 12V, 24V and 48 volts. Use this reference as a general rule of thumb.
