Are Solar Batteries Worth It In 2023?

Are Solar Batteries Worth It In 2023

Back in 2010, Australia saw a surge in solar battery installations all around the country. Since then, about 3 million homes have enjoyed the perks of rooftop solar, including lower electricity bills than those with just a grid connection.   

To paint a clearer picture, it is estimated that in NSW, per kilowatt of energy generated by solar panels saves you about $400 annually. You have a standard 6.6kW solar system on your rooftop, and your savings for the said year will be about $2640, which is $660 in a quarter!    

There is a way in which you could get even more out of your solar panel system; what might that be? Adding a solar battery system is the answer.  

However, batteries for solar systems are by no means a small investment, so the question remains: are solar batteries worth it in 2023 as a homeowner? We will find out soon enough. But first, let’s get to know some basics about solar batteries. 

Types of Solar Batteries

Solar batteries, also called solar energy storage systems, play a crucial role in solar power setups by storing surplus energy generated during sunny periods for later use, such as during nights or overcast days.  

These batteries come in various types, each with distinct characteristics and advantages.  

Lead-acid batteries, including Flooded Lead-Acid (FLA) and Valve-Regulated Lead-Acid (VRLA) options, offer durability and cost-effectiveness, with VRLA batteries like Absorbent Glass Mat (AGM) and Gel batteries being maintenance-free.  

Lithium-ion batteries, such as Lithium Iron Phosphate (LiFePO4), Lithium Nickel Cobalt Manganese Oxide (NMC), and Lithium Nickel Cobalt Aluminium Oxide (NCA), provide high energy density, extended lifespan, and enhanced safety.  

Flow Batteries, represented by Vanadium Flow Batteries, offer a liquid electrolyte and are known for their extended cycle life and scalable capacity.  

Saltwater Batteries, specifically Sodium-Ion Batteries, are environmentally friendly and potentially cost-effective. Nickel-iron or Edison batteries are durable but have lower energy density. Hybrid Batteries combine different technologies for optimised performance.  

Choosing the correct solar battery involves cost, space, maintenance, and intended application, while ongoing advancements in battery technology may introduce newer options. 

Reasons Why You Should Get Solar Batteries

Solar battery prices are not low, but the payback period goes down with the price hike of energy in Australia every day, and due to the current economic environment, I can only see energy prices rise.  

According to the Australian Energy Market Operator (AEMO), the wholesale cost of power in the National Electricity Market (NEM) jumped by 141 per cent in the first three months of 2022 compared to the same quarter last year.  

That said, storing the surplus of energy generated by your solar panels sounds like a sound investment, doesn’t it?   

Here are some more reasons-    

End of Net Metering in Australia

Net metering is a system that allows you to send the excess power generated by your solar panels to the grid and get a portion of the exact amount back on demand.  

People were utilising the grid practically as a storage facility when the net metering system was still in place, but that luxury is no longer available.  

Net metering was available until April 2020 in the Northern Territory; however, the benefit is no longer at one’s disposal for solar systems constructed after that date.  

Essentially, with the end of net metering, you no longer have the freedom to get a one-to-one net metering service (a kW received per kW given).   

That doesn’t mean you don’t have other means to store the energy in the grid; you do; however, that is not as beneficial as net metering and not certainly as profitable as having your solar battery.   

Solar panels can generate a different amount of energy all day, as the sun doesn’t shine as bright from sunrise to sunset.  

The maximum amount of electricity generated by the solar panels is between 12 and 3 pm. An average Australian household only consumes a little electricity during that time since they are the majority at work.    

Studies have shown that, with the surge of electric prices off the grid, it needs to make more financial sense to store the excess energy in the grid; instead, having your solar battery and using it on demand will be much more profitable in 2023.   

Electricity Prices are Higher at Night

As a storage unit does require significant investment, you decided to export the surplus of electricity to the grid.  

But, keeping in mind that an average household requires more energy at night than in the day, you will be paying more to buy back that amount of electricity you exported at night.   

So, it’s evident that storing the surplus in a solar battery makes more sense than repurchasing it at a higher price point.   

Grid Outages

There are occasions in which people suffer from grid outages. It can be during a scheduled check-up of the grid, a devastating storm, or just about any other reason. It’s more common than you would think. In those cases, a solar battery can be your resolve.   

We are positive you would prefer to avoid coming home to a fridge full of rotten food. To have an uninterrupted supply of energy that you have all the control over, having a battery storage unit makes perfect sense.   

Yes, of course, you could opt for a backup generator, but they are noisy, and it defeats the purpose of having installed solar on your rooftop in the first place. It runs on diesel, a non-renewable energy source contributing to carbon emissions.    

Are Solar Batteries Worth It?

home battery storage

It makes sense for a large energy user to opt for solar batteries. They are worth the price, and here is why-   

Solar battery cost is significantly coming down as we speak. For instance, back in 2020, a 6kw solar battery cost about $10,000, which now is about $7,700  

It is the only way to go for those who live off the grid   

Without the benefit of Fit, having one’s storage system saves on power bills even more   

Complete control over your energy consumption   

Power backup for days in the event of a power outage, and with the addition of solar panels, you can forget the grid.     

Solar Battery Storage Price in Australia: How Much Do Solar Batteries Cost?

It’s tough to figure out solar battery prices because it depends on many variables. For example, it will depend on your power needs, whether you have any power-hungry appliances, household size, geographic location, etc.  

Depending on these variables, you can determine how much of a storage unit you require. Thus, That’s how the cost of solar batteries is estimated.   

But to give you a rough idea, the price of a kWh of residential solar battery storage can hover over the $1000 mark.  

These include the cost of installation and GST. Remember that the battery brand and all the other factors mentioned matter in the end, and prices vary depending on those factors.    

10kw Solar Battery Price

As of October 2023 in Sydney, NSW, the current cost of a 10kW solar battery paired with a 6.6kW solar panel system is $12,888. This price includes two 5.1 kWh modules integrated with a 6.6 kW solar system. The potential payback time for this system can be less than 4 years.  

The Tesla Powerwall, which has a storage capacity of 13.5 kWh, costs approximately $1,150 per kilowatt-hour.  

When considering the broader market, solar batteries without the solar component typically fall from $900 to $1,200 per kilowatt-hour. The specific pricing varies based on the brand and model. 

6kw Solar Battery Cost

The solar battery storage cost is how much you pay for each unit of electricity it can store, and it’s usually measured in dollars per kilowatt hour ($/kWh).  

Typically, these batteries cost between $900 and $2,000 per kilowatt-hour. If you want a solar setup with a 10.2-kilowatt-hour battery and a 6.64-kilowatt solar system, it might cost you around $12,888. 

If you just want the battery alone, without the solar system, a solar battery alone can cost $990 per kilowatt-hour. It includes a particular device called a hybrid inverter that connects the battery to the solar system. 

For a specific type of battery called the Tesla Powerwall, which has a 13.5 kilowatt-hour capacity and comes with its inverter, the price is $1200 per kilowatt-hour. 

Another type of battery, the Sungrow 9.6 kilowatt-hour solar battery, is priced at $1227 per kilowatt-hour. This cost includes a 5-kilowatt hybrid inverter. 

If you’re looking at a solar panel system with a 6-kilowatt capacity, and it includes a battery with a capacity of 16.6 kilowatt-hours, the total cost for installing this combined system can range from about $19,935 to an average of $25,235.  

The exact price depends on the type and quality of your chosen system. For more details, check out how much a 6kW solar battery costs in Australia.

They are set up to adopt small-scale renewable energy systems, like solar panel systems, small-scale wind systems, small-scale hydro systems, solar water heaters, and air source heat pumps.  

This initiative benefits Australia’s individuals and small businesses by generating Small-scale Technology Certificates (STCs) 

Established in 2011 to contribute to Australia’s Renewable Energy Target, the scheme has played a pivotal role in promoting the use of renewable energy. 

The success of Small-Scale Technology Certificates (STCs) in boosting the demand for solar installations among households and small businesses is noteworthy.  

Accessible to all Australians, STCs present a valuable incentive. They are applicable for solar panel installations up to 100 kW. 

Each STC holds a monetary value that can be credited to the installer or traded on the open market for a point-of-sale solar rebate. The maximum number of certificates per solar system is determined by the system’s location, installation date, and electricity consumption measured in megawatt hours (MWh).  

This includes electricity generated by a small-scale solar panel, wind, or hydro system over one or five years or a maximum deeming period and electricity displaced by a solar water heater or heat pump over a maximum deeming period. 

The Renewable Energy Target speeds up the creation of tradable STCs, providing a financial incentive for increased electricity production from renewable sources.  

These certificates are issued and distributed through the REC Registry, an online trading platform managed by the Clean Energy Regulator. 

STCs are calculated within the Small-scale Renewable Energy Scheme based on the solar system’s location, installation date, and the duration over which they are generated.  

The scheme is gradually being phased out, with the value of STCs decreasing annually on the 1st of January until 2030, when the scheme is set to conclude on December 31.

Differences Between Solar Batteries And Solar Inverters

Differences Between Solar Batteries And Solar Inverters

Two essential components of a solar panel system are solar batteries and solar inverters. The world is increasingly turning towards renewable energy sources. Therefore, understanding the differences between these two elements is essential.  

There are different roles for solar batteries and solar inverters. There are also significant differences between solar batteries and solar inverters. Today, we will explore their functionalities, significance, and how they contribute to the efficiency of solar panel systems.  

What is a Solar Battery?

A solar battery is an additional component integrated into your solar energy setup. It is designed to store extra electricity produced by your solar panels.  

Its purpose is to store this excess energy for later use. Solar Batteries mainly store energy when your solar panels are not actively generating electricity. Night, cloudy days, or power outages are the simple examples.  

A solar battery helps you utilise more of the solar energy you generate. Without a solar storage system, any extra electricity generated by your solar panels gets directed to the grid.  

It gets distributed to others instead of maximising the use of the electricity your panels initially produce.  

What is a Solar Inverter?

A solar inverter is also a crucial component in a solar energy system. Its primary function is to transform direct current (DC) electricity into alternating current (AC) electricity from solar panels.  

How it works

In electricity, DC maintains a constant voltage in a single direction. At the same time, AC involves the flow of electricity in both directions within the circuit, as the voltage alternates between positive and negative. Inverters belong to the category of power electronics, a class of devices responsible for controlling the flow of electrical power. 

Essentially, an inverter converts from DC to AC by rapidly waving the DC input’s direction. This process results in the transformation of a DC input into an AC output.  

Moreover, by utilising filters and additional electronic mechanisms, the inverter can generate a clean, recurring sine wave that varies in voltage. This sine wave represents the pattern of voltage over time.  

And it is essential for the grid’s use without causing harm to electrical equipment. Electrical devices are designed to function within specific frequencies and voltages.  

The sine wave pattern produced by the inverter ensures compatibility with these requirements, safeguarding the grid and connected equipment. 

Differences Between Solar Battery and Solar Inverter

Both types function as energy storage units. The primary contrast is in their charging methods and connection sources. 

Solar batteries differ from inverters and undergo multiple recharging cycles directly linked to solar panels to receive and store power.  

Their lifespan typically ranges between 5 and 15 years. It depends upon maintenance.  

In essence, solar batteries are tailored for multiple recharges and directly acquire power from linked solar panels.  

In contrast, inverters rely on chemical reactions within the unit for their power source.  

Primary Differences Between Solar Battery and Inverter

solar inverter
  • A solar storage system primarily stores power, whereas the inverter converts AC power into DC. 
  • During a power outage, a solar battery promptly shifts from the primary power source to back up battery power, while the inverter may have an unavoidable delay. 
  • A solar battery system offers standby electrical power while the inverter supplies electronic backup power. 
  • Battery system variations include off-line, online, and line interruption types, while inverters come in standby and grid-connected styles. 
  • The solar battery system connects directly to home appliances, whereas the inverter connects to the storage battery and then to the home appliance circuit. 
  • Solar batteries tend to be more expensive than inverters. 
  • Battery storage and inverter vary in providing backup power.  
  • Solar storage systems usually do not have minimal voltage change. Inverters may have voltage variations. 

Solar Battery vs Normal Battery

A solar battery and a regular battery differ significantly.  

A regular battery is typically called a deep-cycle battery. It represents a rechargeable battery extensively used in various applications, such as backup power. 

These batteries store electricity and are rechargeable through multiple sources like generators or the grid. Typically composed of lead-acid, flooded-type, or sealed-type batteries, they cater to diverse functionalities. 

On the contrary, a solar battery is purpose-built to store surplus electricity generated by a solar energy system.  

This stored energy becomes accessible to homeowners when solar panels are inactive. Solar batteries go through numerous charge and discharge cycles.  

Primarily, they are composed of lithium-ion or flow batteries. One of the significant differences between both battery types is that one specialises in solar energy systems. 

A solar and a regular battery represent distinct choices for powering a solar energy system, with the former being purpose-built for storing excess solar-generated electricity.  

Solar Inverter vs Regular Inverter

When you’re thinking about buying an inverter for your home or business, you might wonder about the differences between a solar inverter and a regular inverter.  

But it’s more complicated to answer because many things are different. For example, how they work and the battery they use. It’s vital to understand these differences well before you decide which one to buy.  

Regular Inverter Functions

The regular inverter utilises switching mechanisms to control circuits, transforming direct current (DC) to alternating current (AC). This conversion process is a fundamental objective shared by both types of inverters. 

A typical power inverter draws DC power from batteries and transforms it into AC power utilised by various appliances.  

Typically linked to the home’s power system, the inverter and its battery are part of this setup. When grid power is available, the batteries are charged; in the absence of grid power, the inverter usually switches to battery mode, allowing the use of essential appliances. 

Solar Inverter Operations

In contrast, a solar inverter encompasses components such as solar panels, a charge controller, switching circuits, batteries, and the inverter itself.  

It includes connecting appropriately rated batteries and solar panels—the inverter’s battery charges from solar panels when sufficient sunlight is available. The solar panel within a solar inverter generates variable DC, which the inverter converts into AC. 

Using a solar inverter aids in reducing electricity bills and is a viable option for both residential and commercial spaces.

Integration Between Solar Panels, Batteries, and Inverters

solar power systems

You might be wondering about solar panels. However, many questions about the necessity of an inverter and a solar battery may arise. 

Solar panels are the fundamental part of harnessing the sun’s energy. Essentially, solar panels function by collecting sunshine and transforming it into electricity. The process is straightforward. 

To capture the sun’s energy, solar panels have a negatively charged side and a positively charged side. When sunlight hits the panel, it energises the electrons within, enabling them to move from the opposing side to the positive side. 

However, this electricity is in its “raw” form, known as DC (direct current), whereas most household appliances operate on AC (alternating current) electricity. That’s where an inverter becomes essential.

Solar Inverter Integration

Solar inverters are crucial in transforming electricity to be accessible and secure. If solar panels represent the fuel tank, then solar inverters serve as the driving force. 

While generating DC electricity is essential, its usability hinges on converting solar inverters into vital AC. This conversion is important for making electricity practical for everyday use. 

These inverters significantly impact the system’s performance. Solar inverter goes beyond mere efficiency. These devices influence the quality and safety of the generated electricity. 

Traditionally, most systems incorporate a single solar inverter linked to the solar panels. However, technological advancements have led to the emergence of micro-inverters.  

These smaller inverters attach directly to individual solar panels, enabling personal monitoring and optimisation. 

This innovation not only boosts the power output for homes but also offers a significant advantage. If one panel malfunctions, the others continue to function independently.  

Solar Battery Integration

solar battery

Solar batteries serve as repositories for the surplus energy in a solar panel system. While solar panels and inverters shape the core components of a PV system, adding a battery is still optional. 

The primary work of a residential solar system revolves around creating energy during blackouts or saving money. 

When you need a lot of energy, you might use regular power lines, which can be expensive. If you make more energy than you require, it returns to the system, and you get credits for it on your future bills. 

A solar battery is like the batteries in your gadgets or cars. It stores extra electricity made by your solar panels. This stored power helps when the weather is cloudy, so you have electricity when needed. Instead of sending extra power back to the system, the battery keeps it for you. 

You don’t have to get a solar battery, but it’s a good idea. It can cut your electricity bills by another 75%, besides what you save from making your energy. 

If you’re getting a solar system, it’s smart to include a battery from the start. This makes the whole system work better and saves you more money.

So, if you need clarification on why your Powerwall batteries don’t reach 100% charge daily, start monitoring your energy production and consumption.

Powerwall Battery Charging

The charging behaviour of your battery is contingent upon the selected features. Typically, users employ one of two configurations:

Powerwall First: In this setup, your Powerwall and batteries will get priority for charging, with any surplus energy allocated to utilise your solar panels.

Solar Panels First: Consequently, this configuration prioritises charging your solar panels first, with any extra energy redirected to charge your Powerwall battery.

The resumption of the Powerwall function typically occurs automatically. Although occasionally, you may need to reset the circuit breakers.

Grid vs. Solar Energy

Depending on your settings, the Powerwall may charge using surplus solar energy after meeting household energy needs, or the opposite may occur.

Access to grid energy is limited to specific situations:

Activated Storm Watch Feature: The Powerwall automatically draws power from the grid in preparation for anticipated outages if Storm Watch is enabled.

Absence of Solar Power: In cases where solar power is entirely unavailable in your area, permission may be granted for your Powerwall to tap into grid energy.

Powerwall’s Storm Watch feature

Storm Watch is a feature that helps you get ready for power outages. Storm Watch is a feature that prepares you for power outages. It prioritises charging your home and solar devices from the grid. This allows you to save your solar energy and Powerwall battery for when you truly require it.

How Do I Turn It Off?

The Storm Watch feature is activated by default. To turn it off, go to the home screen, choose ‘customize,’ find ‘Storm Watch,’ and move the toggle switch to ‘off.’

Why Powerwall Not Covering Outages?

If your Powerwall fails to function during outages or experiences frequent failures in such situations, several potential causes may be at play:

Battery Consumption: Your Powerwall battery may have been completely discharged, and insufficient solar energy is available for recharging. This can occur during extended outages, especially if users must be aware of their energy consumption versus production.

Amperage Overload: Each Powerwall has a maximum amperage capacity, representing the electricity it can supply to devices. Overloading your Powerwall with too many appliances can prevent them from handling outages effectively.

Electrical Flickering: If your lights and appliances frequently turn on and off, it may result from momentary electrical surges. These surges can prevent the Powerwall from initialising, causing the flickering issue. Reducing the amperage load can resolve this.

Long Power Outages: Unfortunately, during long outages with no access to both grid and solar power, your Powerwall battery. In such cases, you may need to wait for power to be restored or consider alternative power sources like a generator.

When anticipating long blackout outages, it’s advisable to prioritise energy-intensive activities to conserve Powerwall capacity when the grid goes down.

Victorian Government’s Interest-Free Solar Battery Loans

Victorian Governments Interest Free Solar Battery Loans

The Victorian State Government has announced an innovative battery loan program for its $1.3 billion Solar Homes Program. This program aims to encourage residents to switch to renewable energy sources.  

Under this initiative, Australian homeowners can access interest-free solar battery loans to install battery systems alongside solar panels. These loans will reduce upfront installation costs and enable solar storage to maximise energy output. 

Minister for Energy and Resources, Lily D’Ambrosio, introduced an $8,800 interest-free battery loan. It will empower households to harness the full potential of their solar panels and save thousands of dollars on energy bills over the battery’s lifetime.  

The ultimate goal of this program is to bring down energy expenses for Victorians. And it will contribute to the state’s commitment to achieving net-zero emissions by 2045. 

Using the battery loan scheme, homeowners with existing solar panels can significantly increase their self-generated energy consumption. Consequently, this will double its current capacity.  

Additionally, new customers can take advantage of the loan alongside the pre-existing $1,400 rebate and the $1,400 interest-free loan for solar photovoltaic (PV) technology. Ultimately it will save eligible households $11,600 on upfront installation expenses when installing solar and battery systems simultaneously. 

After applying for the solar PV rebate and federal government small-scale technology certificates (STCs), the out-of-pocket installation costs for a solar and battery system can start at approximately $10,300.  

For those interested in a standalone battery, prices range from about $8,000 for a 6kW/h battery to around $17,000 for an 11kW/h battery. 

Minister Lily D’Ambrosio highlighted the significance of interest-free batteries in facilitating the transition to cheaper renewable energy. The initiative aligns with the state’s ambitious renewable energy target of 95% by 2035, promoting adopting reliable and affordable green energy solutions. 

With the Solar Homes Program’s efforts, carbon emissions in Victoria have already been reduced by 1.7 million tonnes.

Here Are Some Points To Consider:

  • The homeowner will still need to come up with $5,400 upfront, even after factoring in the $1,400 solar rebate and the $10,200 loan. 
  • It’s important to remember that the battery’s capacity will degrade over time. So adding another 3 months to the payback period would compensate for this degradation. 
  • The calculations are based on a fixed tariff of 27c per kWh. For those on a time-of-use tariff, the payback for the battery maybe even better.

A Quick And Approximate Analysis

Utilising the Solar and Battery Calculator assumes a $17,000 system consisting of 6.6kW solar panels and a 9.8 kWh solar battery 

Allocating $6,000 to solar panels and $11,000 to the battery for a homeowner in Melbourne with a pre-solar bill of $2,500 per year. The results indicate average savings of $142 per month in the first year. 

If the loans come without any finance costs, the combined savings would take approximately 6 years to cover the $10,200 loan.
