In recent years, Australia’s energy costs have escalated significantly. Also, with growing environmental concerns, many Australian homeowners and businesses are now exploring solar battery storage as a reliable solution.  

But is investing in solar battery storage truly economically viable? 

From potential energy savings to long-term economic and environmental benefits, the answer to this burning question depends on several factors. 

So, let’s find out whether these advanced solar battery technologies can pave the way for a brighter, greener, and more economically stable future! 

Powering Your Home with Solar: The Role of Battery Storage

Before delving into the details, let’s answer a simple fundamental question: what is solar battery storage? 

Well, a solar battery storage system can store the excess electricity generated by the solar panels during peak daylight hours. People can use this stored energy anytime during cloudy days or stormy nights when the solar output is low.    

With solar batteries, you don’t have to rely on grids. Also, it helps you to enjoy the full advantage of electricity generated by your solar panel.   

How Solar Batteries Convert Sunlight into Stored Energy?

Solar batteries work in a pretty simple way. After proper installation with a new or existing solar panel, the battery undergoes a few easy steps to convert sunlight into stored energy. 

  1. When sunlight hits the solar panel’s surface, photons are trapped inside. The energy is then directly converted into DC electric form through photovoltaic cells. 
  2. After ensuring the proper voltage, this controlled DC electricity is stored inside the solar batteries for later use.  
  3. When sunlight is unavailable or in case of power outages, these solar batteries send DC electricity to an inverter.  
  4. The inverters finally convert DC electricity into AC to power your home and ensure a constant, reliable power supply.  

Explore Types of Solar Batteries

According to the latest data, Australia is known as the world’s largest lithium producer, a crucial battery component. 

The country’s extensive lithium deposits and established mining industry make it the leading supplier around the world. 

Curious to learn more about solar batteries in Australia 

Let’s start with the primary battery types: Lithium-ion and Lead Acid batteries 

Lithium-ion and lead-acid batteries are two more common names in the solar battery realm due to their high energy density, better efficiency, and longer lifespan.  

Lithium-ion:  

Around 60 to 70% of new residential solar energy storage in Australia uses Lithium-ion batteries. They are compact, require less space, have a 15-year lifespan, and require little maintenance.   

However, the major drawbacks include its higher upfront costs and high temperatures, which can also reduce the battery’s efficiency to a certain level.  

Lead acid:  

Lead-acid batteries, which date back to the 1800s, are the oldest battery types. They are the most reliable and affordable battery storage option for people with limited budgets. 

Even though lead-acid batteries can withstand high temperatures, their shorter lifespan, low depth of discharge (DoD), and bulky size make them less attractive options for residential setups.    

However, flow batteries and Sodium Nickel Chloride are the other two battery types used in solar battery production. 

Flow batteries:  

Flow batteries can be a good option for large homes or commercial buildings. Their lifespan ranges between 5 to 15 years, and perform efficiently even with low voltage.  

It has a high-temperature tolerance and can discharge fully without impacting battery health. However, solar installers usually avoid this type of battery as it’s large and heavy and requires expert maintenance.   

Sodium nickel chloride: 

Sodium nickel chloride batteries use salt and nickel to generate power, but these batteries are still not widely available in Australia. They have high power density and an average lifespan of 15 years. 

Solar Battery: Are They worth investing?

Solar batteries can be a game changer if a solar panel is installed on your rooftop. It will take your solar experience to a new horizon by saving you money on electricity bills when the price rises. 

A smart solar panel system can help you build an eco-friendlier home with a reliable and constant power source. It can also help you stay stress-free during unexpected power issues due to grid failure or adverse weather conditions.  

Moreover, installing a smart meter allows you to sell excess stored energy to the grid and earn money. So, merging solar and battery systems can create economic opportunities and several environmental benefits. 

So, don’t you think solar batteries can be a smart move for your wallet? I’m pretty sure it is!
