Is It Worth To Have Tesla Powerwall For Australian Houses

More Australians have solar panels installed in their homes. And as feed-in-tariffs continue to fall across the country, more Australians are turning to batteries to store their excess solar energy.  

Like all the other battery storage systems, Tesla is becoming a household name in Australia. However, is the Tesla Powerwall worth it for Australian houses in 2023? 

A residential battery can double your use of self-generated energy. So installing a Tesla Powerwall in your home will double your benefits. Also, it is better for the environment.  

However, how quickly it works depends on the amount of energy you put in. So, there are several factors to consider if the Tesla Powerwall is worthwhile for you in 2023 

If you’re an Australian looking for a home solar battery, you’re probably thinking about the Tesla Powerwall. It’s arguably the most popular home battery on the market now. In this article, we’ll review why the Powerwall is Australia’s favourite home battery.

But First, What Is Tesla Powerwall?

Tesla Energy’s Tesla Powerwall is a rechargeable lithium-ion battery. It is a home energy storage product. The Powerwall stores electricity for solar self-consumption and electricity load shifting at different times of the day.  

The Powerwall is a rechargeable home battery system designed to increase energy independence at your home. It means continuous backup, a lower carbon footprint for your home, and lower electricity bills.  

Powerwall is an intelligent system that can be tailored to your specific energy requirements. This battery can charge from solar, ensuring that energy is always available on demand. 

It also works as a backup power. The Powerwall was released in 2015 in limited quantities.  Now Tesla offers larger battery storage devices – the Powerpack is designed for business use, and the Megapack is designed for grid use.

History Of Tesla Powerwall

Tesla Motors began experimenting with using batteries for energy storage as it developed batteries for its electric car business. Tesla started installing prototype battery packs at the locations of a few industrial customers in 2012. 

The company later announced in November 2013 that it would construct a lithium-ion battery manufacturing facility in Giga Nevada.  

On April 30, 2015, the company announced that it would use its battery technology to create the Powerwall, a home energy storage system. And customers could use the device to store electricity for solar self-consumption, time-of-use load-shifting, and backup power. 

The device was initially announced to have a power output of 2 kW continuous and a 3.3 kW peak. But CEO Elon Musk later stated that the Powerwall would be more than doubled to 5 kW and 7 kW peak, with no price increase. 

How Does Powerwall Work?

Powerwall allows you to store energy for later use and works with solar to provide essential security and financial benefits. Each Powerwall system includes energy monitoring, metering, and smart controls.  

The owner can customise and control all of these via the Tesla app. Over time, the system learns and adapts to your energy consumption. And then it receives over-the-air updates to add new features and improve existing ones. 

Powerwall and Powerwall+ are two types of Powerwall 

Powerwall is a rechargeable home battery system that can be used with solar panels. A Powerwall system can consist of up to ten Powerwalls. It can be a mix of Powerwall+ and traditional Powerwalls.  

A Powerwall+ includes additional solar integration features that provide cleaner installations with less equipment. 

Integrated energy metering can assist you in accurately monitoring your solar production and home energy consumption for precise, real-time insight into your home energy.  

Powerwall+ can intelligently power heavy equipment, and direct solar integration improves solar recharging during power outages. It results in a better off-grid experience.  

Here are some examples of Powerwall integration-  

Solar And Tesla Powerwall

Solar and Tesla Powerwall

Integrating Powerwall with solar is the best way to maximise the value of your system. It provides you with solar power at any time of day or night.  

Powerwall+ provides a complete, integrated solution, providing whole-home backup with solar. On the other hand, Powerwall can be integrated with existing solar systems. 

Because the Powerwall is an AC-coupled system, it is compatible with standard inverters used in home energy systems. At least one Powerwall is required for each 7.6 kW AC of solar included in the backup circuit to ensure reliable operation during power outages. 

Generators And Powerwalls

Powerwall can be added to a system which already includes a backup generator and an external Automatic Transfer Switch (ATS) or Manual Transfer Switch (MTS). 

The Powerwall is usually installed between the utility meter and the transfer switch. And it can charge from solar while the grid is up and running. Although, the Powerwall and generator are not directly integrated. So, the Powerwall does not charge from the generator. 

Powerwall responds immediately in the event of an outage and provides backup power before the generator can detect the outage. The generator is activated only when the Powerwall’s charge is low or when electrical loads exceed the Powerwall’s maximum output. 

When grid power is restored, the generator will be turned off, and the Powerwall will be able to charge from solar once more. If a Powerwall is installed with an MTS, the switch must be manually operated to power the home with the generator.

Electric Vehicle Charging & Powerwall

Powerwall can deliver stored solar energy to your electric vehicle through your home’s electrical panel. However, there is no direct link between Powerwall and charging equipment. 

Although rechargeable electricity storage technologies have been under development for decades, the potential for residential solar storage has only recently become apparent. 

The Tesla Powerwall was not the first solar battery, but it received the most attention. 

The Tesla Powerwall 2, is widely regarded as some of the market’s go-to solar batteries.  

But does the Tesla Powerwall live up to its hype? Solar Emporium’s solar experts have examined the entire Tesla Powerwall range, including specifications, prices, and capabilities.  It will eventually help you determine whether it’s worth installing in your home. 

But let’s get to know the benefits first.

Reduced electricity bills

The ability to reduce electricity bills is the primary benefit of owning a Tesla Powerwall. The Powerwall collects and stores solar energy generated by your solar panels during the day, which it then uses to power your home at night.  

You can significantly reduce your dependence on the grid with the Powerwall. It means you’ll buy less electricity from your energy provider. As a result, your monthly electricity bills will be reduced. 

Enhanced energy independence

Installing a Tesla Powerwall can help you become more energy independent. You’ll be less reliant on the grid for energy. And it will eventually give you more control over your energy supply.  

This is especially useful during power outages or when grid power is unstable. The Powerwall keeps your home powered up at all times, even during emergencies. 

Carbon footprint reduction

Tesla Powerwall is a green solution that can help you reduce your carbon footprint. It collects and stores excess solar energy during the day, which can then be used to power your home at night.  

This reduces the energy you consume from the grid, which is generated using fossil fuels. You can contribute to a cleaner, greener environment using solar energy stored in the Powerwall. 

Increased property value

Adding a Tesla Powerwall to your home can increase its value. Homes with solar battery storage systems are becoming increasingly popular as more Australians become aware of the benefits of renewable energy.  

Installing a Tesla Powerwall can make your home more appealing to potential buyers if you decide to sell your property anytime soon. 

Monitoring and management of energy

The Tesla Powerwall comes with an app. And you can remotely track your energy consumption and production in real time.  

You can see how much energy your solar panels generate and how much your home consumes. This information assists you in making informed decisions about how and when to use energy in your home.  

You can also set up alerts to notify you about the Powerwall’s battery percentage and power outages.

Continuous Backup

Solar energy will provide you with continuous power if an outage occurs. Powerwall can communicate with the National Weather Service and prioritise charging in any case of severe weather.  

You will receive notifications from the Tesla app if the status of your Powerwall changes due to weather. 

Powerwall has several essential features for Australian conditions. In addition, it has cutting-edge technology backed by a 10-year warranty. 

Tesla Powerwall can also support some other aspects of energy-efficient living- 

  • Power reserve 
  • Control Based on Time 
  • Off-grid living 

Price For The Powerwall

The Powerwall’s price was raised for the first time in late 2018, to AU$10,000. Surprisingly, there were two more price increases in 2020, bringing the price to around AU$ 11,000.  

Several price fluctuations occurred in 2021, but the price increased dramatically in 2022, with three consecutive price increases. The first modest price increase of $950 was announced in March.  

The second in May, and the most recent in October. It raised the cost of a Powerwall system to 16,000 Australian dollars.  

The Powerwall was one of the most affordable AC-coupled battery systems when it was first released. However, it became one of the more expensive options available. 

But following years of price increases, 2023 has seen two reductions. That brought the price down to under $13,000 in Australia. 

So with different solar and storage rebates, many Australians are moving toward Tesla Powerwall again 

Tesla Powerwall Warranty for Customers in Australia

Solar batteries are covered by a time and throughput warranty. The time warranty covers many years during which faults can be claimed.  

Whereas the throughput warranty specifies the number of kWhs discharged or cycles completed before the warranty expires. 

The Tesla Powerwall 2 has a ten-year warranty against defects, with the usual exclusions such as improper use or installation. The warranty also includes a maximum degradation to 70% of the throughput capacity of 13.2kWh at the end of the ten years.  

It means if your battery can only discharge 9.2 kWh or less after ten years, you may be eligible for a warranty claim.

Tesla Creating Trends For Renewable Technology

From electric cars to integrated renewable energy solutions, Tesla is doing it all. The company is known for producing innovative, high-performing, sustainable, and trendy products.  

Tesla made electric cars cool and desirable. And now it’s doing the same for home batteries. 

The first-generation Powerwall hit the market in 2015. It surprised the energy storage market. The first high-voltage battery for home use, the unique DC-coupled lithium storage had a modest 6.4kWh capacity.  

The Powerwall 2 second generation was released in 2016, with more than double the storage capacity and an integrated battery inverter-charger. Giving it significantly more power and flexibility. 

In Australia, the home battery market is gaining traction, and data shows that the majority of homeowners are opting for a Tesla Powerwall. 

A 400% increase in battery installation occurred by the end of 2021. And the majority chose Tesla Powerwall. With our affordable solar packages, you can make your dream of owning a Tesla Powewall into reality.

What Are The Best Solar Batteries?

Solar batteries for home energy storage typically comprise one of three chemical compositions: lead-acid, lithium-ion, or flow batteries. In most cases, lithium-ion batteries are the most cost-effective option for a solar panel system. However, other battery types may be available.

How To Evaluate Solar Storage Options

Considering solar energy storage system options, you’ll encounter many complicated product specifications. It may create more questions about the best equipment to match your solar battery.  

To evaluate your solar battery options, you should first understand its capacity to store energy and power ratings. Then it would be best to compare the depth of discharge (DoD), efficiency, and warranty. 

Calculating the Size of Your Solar Battery System

Properly sizing your battery is critical. But consumers and solar installers may frequently overlook it. Batteries in PV systems are often undersized due to cost or underestimation of system loads.  

Understanding the customer’s energy requirements and correctly designing a plan that best meets their objectives is very important. Solar battery manufacturers’ online system sizing calculators can help simplify determining battery capacity for load requirements. 

How long will a solar battery last?

The lifespan of a solar battery varies from 5 to 15 years, depending on the type. Lithium batteries have a lifespan of up to ten years. Lead-acid batteries have a lifespan of 3–5 years. 

How Many Hours Of Energy Can A Solar Battery Provide?

Several factors determine this. These factors will help determine how long you can power your home. 

 The most significant factors to consider are:  

  • Number of appliances running in your house 
  • Your battery’s total capacity 

Considerations When Purchasing Solar Batteries

solar plus storage

Various factors should be considered when calculating the total cost of installing a solar battery to your solar energy system.  

Price: A solar battery with a low upfront cost may sacrifice quality and battery life; you may offer a lower upfront cost for a significantly higher future cost. But the need for frequent battery replacements may increase the cost over time.  

That is why, when deciding, it is critical to consider all factors other than price. 

Capacity: Battery capacity is significant because it represents the energy the battery can store. 

Voltage: The voltage of the solar battery bank should be considered to ensure that it meets the requirements of the solar system. Your solar energy system will include a solar inverter. Depending on the voltage of your solar battery bank, you may need to purchase a different inverter.  

The inverter specifications determine the voltage of the solar battery. Ideally, it should be installed on a system that converts DC-to-AC energy so that the voltage of loads in a DC energy system.  

Cycles: The cycles of a solar battery are the most crucial factor to consider. The battery cycle indicates how many discharge/charge cycles it can provide before capacity drops to a specified rated capacity percentage.  

Solar batteries with the same power, energy content, and weight may exist. However, the battery’s design, material, and quality will influence how many times it will cycle appropriately over its lifetime.  

Maintaining Solar Batteries

Let’s assume the installation process is done. But your work isn’t done yet. You still need to maintain a few things to have a properly running battery to power your house. Here are a few things you can keep on checking:  
  • If it’s kept in a protected space or not  
  • How is the backup process 
  • How much backup is the battery providing for your appliances  
  • Is the monitoring app or device working well or not  
  • Is the battery providing enough off-peak power  
  • Are the transformers working correctly or not

What Type of Batteries To Use With Solar Panels

What Type Of Batteries To Use With Solar Panels

Solar energy systems typically comprise solar batteries and panels, mounting tools, and an overall performance monitoring system. Solar energy systems 

Most houses are connected to the grid. These systems are more commonly used for backup among homeowners. Many people, however, are looking for a replacement for their utility supply. One common reason people switch to solar is to avoid high energy costs. 

So what type of batteries to use with solar panels to avoid high energy bills?  

Various type of solar batteries are used as a backup for critical loads when the grid fails. You can choose from multiple types of solar batteries to use for your system. These solar batteries are designed to provide auxiliary power to the grid. 

As we all know, four different types of solar batteries exist in the solar industry.  

  • Lead Acid Batteries  
  • Lithium-ion Batteries  
  • Nickel-cadmium (Ni-Cd) Batteries 
  • Flow Batteries 

Lithium-ion and lead acid batteries are the most used of these four batteries. For a detailed review of all these batteries, check out our last blog about 4 different types of solar batteries. 

Lead Acid Batteries

For many years, lead-acid batteries have been a reliable energy supply for off-grid areas. They are typically deep-cycle and low-cost. Lead-acid batteries are known for their high power and discharge current but low energy density. They can take up to 14 hours to charge fully. 

Because of their highly toxic nature, these batteries should be thrown away properly. Otherwise, it can threaten the environment. 

The flooded lead battery is dependable but must be watered and ventilated to function correctly. The VRLA comes in two varieties: gel and absorbed glass mat (AGM), which have valves for off-gassing regulation. These are appropriate for cold and warm temperatures. Although VRLA batteries provide enough installation flexibility, their temperature sensitivity may pose a challenge to people looking for a permanent alternative to their grid supply. 

Li-on batteries for bet efficiency

Lithium-ion Batteries

Lithium-ion batteries are becoming a more popular choice for solar systems worldwide. The development of this type of battery is heavily influenced by its application in the electric vehicle industry. Its prism shape allows ventilation which is beneficial in solar systems. 

Lithium-ion batteries have a distinct voltage range and charging response. A voltage regulator charge controller is used to charge them. Despite low self-discharge, lithium-ion batteries do not benefit from long-term charging. 

This type of solar battery requires little to no maintenance and has a high energy capacity and a long lifespan. Lithium batteries are evidently more expensive than lead-acid batteries. They may also need a protection circuit to regulate the current and voltage. 

Lithium-ion batteries can provide more cycles than lead-acid batteries. It makes them ideal for providing additional services to the grid. Lithium-ion batteries’ high charge and discharge efficiencies make them an excellent choice for solar systems.  

These batteries also lose less capacity when unused. That is very beneficial in solar installations where energy is only used occasionally. 

In Comparison, Which Battery Is Better?

Capacity

The capacity of a solar battery simply describes its ability to store electrical power. Because of their heavier weight, lithium batteries have a higher degree than all other types of lead-acid batteries.  

To power a 5.1kW, you’ll need about 8 lead-acid batteries, whereas two lithium-ion solar batteries will suffice.  

Because lithium batteries have a higher energy density. They can be installed in difficult places because they can also fit more capacity into less space. Both nickel-cadmium and sodium nickel chloride have a broad capacity range.  

DoD (Depth Of Discharge)

The DoD of a solar battery is the usable portion of its capacity, and a DoD of at least 40% is recommended for optimal battery usage. Lead batteries have a DoD of 50%, whereas nickel-cadmium batteries have a DoD of 15%. 

Exceeding this limit before recharging reduces battery life. In contrast, lithium-ion and sodium nickel chloride solar batteries have an 80% DoD, implying a higher usable capacity. 

Warranty Of Solar Batteries

When deciding which solar battery to use in your system, consider its battery life as the best indicator of its ability to retain capacity. One charge cycle is the chargeback up from a discharge and is the primary determinant of battery lifespan.  

In addition, the number of cycles your solar battery will go through will be determined by the frequency with which it is used. This characteristic varies even for the same type of solar battery and is influenced by the battery’s depth of discharge.  

A warranty is always a good indicator of dependability in any brand or product, including solar batteries. 

Effectiveness

The round-up efficiency is the difference between the available energy and the amount of energy used to charge a solar battery 

The higher a battery’s round-trip efficiency with the DoD, the better. Regarding 95% efficiency, lithium-ion solar batteries win because they have the most conversion rate from solar power.  

This means that depending on the configuration of your system, you may need to install fewer solar panels and batteries. 

Charge Rate

Another factor to consider when purchasing a solar battery is the charge rate. It indicates how quickly a battery will be recharged when connected to a charger. It is expressed in fractions like C/4 function capacity.  

With a charge rate of C/5, lead-acid solar batteries can take up to twice as long to charge as lithium-ion solar batteries, especially during peak hours.  

Lithium-ion batteries and flooded lead-acid are ideal for full-time, off-grid power at various levels of use. If you need a battery for a vacation home or somewhere you won’t spend much time during the year, a sealed lead-acid battery is your best bet. 

It has a low self-discharge rate and requires no maintenance. 

You must consider power outages when purchasing a battery solely for backup purposes. It will help determine how frequently you’ll need your grid supply throughout the year.  

A low-maintenance battery, such as a sealed lead-acid solar battery, will be more beneficial if only used a few times.  

However, after examining other comparisons, lithium-ion batteries are the correct choice. These batteries have better capacity, DoD, warranty, and charge rate.   

Considering these parameters, you can accurately plan and install your solar system. You can choose which type of solar battery is best for you based on your intended system use.  

What Is A Solar Charge Controller?

The solar charge controller is a device that connects your solar panels and batteries. The controller ensures that your batteries are not “overcharged.” Overcharging your batteries causes them to overheat and catch fire. 

A controller also determines how to properly charge your batteries by varying the flow of amps and voltage rate based on the battery manufacturer’s recommended specifications. 

The market is flooded with low-cost solar charge controllers. There are better places to cut corners. Spend a little more money on a high-quality solar charge controller. 

All batteries are replaced at some point. Therefore, you need to decide wisely on the storage system. You’ll need to spend more time researching if you buy expensive batteries. It will help manage them more to get the most out of them.

What Are The 4 Different Types Of Solar Batteries?

What Are The 4 Different Types Of Solar Batteries

Before getting a solar battery, you need to know the different types of solar batteries and their specifications. There are 4 different types of solar batteries available for you.  

Let’s get a background of solar batteries first!  

In summary, solar batteries store excess energy produced by solar panels. When energy output is low, you may use the excess energy to power your home. For example, you can use the sun’s energy on cloudy and rainy days or even after sunset.  

Using solar plus storage depends on various reasons like climate and topography to culture and way of life. Most people in Australia work during the day. Therefore, automatically they consume less energy during the daytime.  

But that’s when solar panels collect most sunlight to convert it to electricity. And that’s what demands the development of storage technology.  

Differences Between Solar Batteries and Regular Batteries

Solar batteries are specifically built to store and release renewable energy on demand. They are made with different materials than ordinary batteries to handle the slower charge/discharge rates associated with dependable solar energy sources. 

Traditional batteries have limited energy stored in a single cell, making speedy charging difficult. Solar batteries, on the other hand, have two or more cells and may provide electricity for a much longer period. 

Solar batteries can also be lead-acid, nickel-cadmium, or lithium-ion. Instead of a standard battery, a solar system will provide more energy over time and not leak heavy metals into the environment after completing its life cycle. 

Solar Battery Types

different types of solar batteries

Four primary types of batteries are used to store electricity from solar power systems. The following section summarizes commercially available technologies and information on each type. 

Lithium-ion Batteries

Maintenance of Lithium-ion batteries is relatively easy. These batteries have higher energy density than other batteries. That’s how they can store more energy in a smaller space. Li-ion batteries also have a longer life cycle. Most of the batteries are guaranteed at least ten years.  

However, one of the most significant downsides of lithium-ion batteries is their higher cost than other energy storage technologies.  

Furthermore, because of their chemistry, lithium-ion storage systems are more likely to catch fire due to a phenomenon known as thermal runaway.  

Although, if properly fitted, the chances of your battery catching fire are almost zero.  

Lithium-ion batteries are ideal for residential solar installations because they can store more energy in a smaller space and allow you to utilise more of the stored energy. 

Nickel-cadmium (Ni-Cd) Batteries

Nickel-cadmium (Ni-Cd) batteries are less popular than lead acid or lithium-ion batteries.   

These batteries first came into the market in the late 1800s. After the remodelling in the 1980s, they considerably boosted the energy they could store. Ni-Cd batteries are the most popular in the aircraft industry.  

The fundamental advantage of Ni-Cd batteries is their long life. They are also capable of operating at high temperatures. Furthermore, they are almost maintenance-free and do not require complex battery management systems. 

But Ni-Cd batteries are exceedingly poisonous because of cadmium. Consequently, cadmium use is prohibited in various countries. They are also vulnerable to the memory effect, which reduces their ability to keep a charge.  

But because of their endurance, Ni-Cd batteries are useful for large-scale applications such as utility solar energy storage.  

Flow Batteries

Flow batteries are a new technology in the energy storage industry. They contain a water-based electrolyte liquid between the battery’s two chambers or tanks.  

When charged, chemical reactions occur, allowing the energy to be stored. These batteries are becoming increasingly popular. 

Because of their larger size, they are more expensive than other batteries. The cost and size make it difficult for household use. 

One of the best features of flow batteries is their 100% depth of discharge. This means you can use all the energy in the battery without damaging its mechanism.  

Unfortunately, these are far more expensive than other types of batteries. They also have an insufficient storage capacity compared to other battery systems.  

Flow batteries serve better in large-scale systems. Because of how they work, they must be huge enough to hold any significant quantity of energy.  

Lead Acid Batteries

Lead acid batteries are the most tested and reliable technology in the solar battery industry. These deep-cycle batteries date back to the 1800s. And they’ve been able to stay because of their dependability.  

These batteries have been classified as flooded batteries and sealed batteries. Lead acid batteries are the least expensive energy storage, making them the most cost-effective. They are also trustworthy because of the long industry journey.  

To function correctly, flooded lead acid batteries require ventilation and maintenance. That increases the likelihood of the battery leaking. Also, their low depth of discharge (DoD) results in more frequent charging.  

They have a lifespan between 5 and 10 years because of their modest depth of discharge. Lead-acid batteries are ideal for off-grid solar systems and backup storage for a power outage. 

How to Choose the Best Solar Battery Type for You

The two main distinctions are the battery’s chemistry and whether it is AC or DC-coupled. Which battery is best depends on when you plan to install it, how frequently you plan to use it, and how much space you have. 

A lithium-ion battery is usually the best option for a residential solar installation. They can store more energy in less space, discharge most stored energy, and have high efficiency.  

Furthermore, because these are the most popular, many solar businesses can precisely and safely install a Li-ion solar battery.  

If you are on a tight budget, lead-acid batteries may be the ideal alternative. They have been used for decades and are cheap.

The type and size of the battery selected determine the cost of a solar battery or battery system. Lead-acid batteries have a lower initial price to the consumer than lithium-ion batteries.  

However, investing in a lithium-ion battery may save money in the long run, depending on how the batteries are used.  

Check out Solar Emporium’s lucrative solar storage packages! 

Depending on size and power, a single lead-acid battery can cost between $200 and $800. Although to keep a household fully powered, it may require multiple lead-acid batteries.  

On the other hand, a household lithium-ion solar battery system with installation costs between $7,000 and $14,000. 

Nickel-cadmium and flow battery prices vary depending on the size and scale of the installation. Because of the expense, durability, size, and stability in extreme temperatures, they are sometimes utilised in residential houses. But these are better suited for commercial and industrial environments.

Number Of Solar Panels And Batteries Needed For Aussie Homes

Number Of Solar Panels And Batteries Needed For Aussie Homes

When it comes to solar, there is no one solution. It is exactly like shopping for other necessary products that you need. Every person has different solar needs depending on many factors.  

So what is the number of solar panels and batteries needed for Aussie homes? To understand everything go through this Aussie batteries and solar review. 

For example, a 5kW solar system typically comes with 15-20 solar panels. It is usually sufficient for an average Australian home. Still, putting as many solar panels on your roof never hurts.  

However, the size of your solar system is determined by electricity usage, how much (unshaded) roof space you have, your budget, and a few other objectives. 

Getting solar panels is only worthwhile if you install enough to cover your electricity requirement. Similarly, you want to save money on a manageable solar system. 

How do you determine the number of solar panels and batteries you’ll need to power your home? 

How Much Power Do You Consume?

The goal is to match your household’s electricity consumption with solar energy. If not, then it may exceed a bit. Ideally, your solar system should produce enough electricity to meet your needs.  

Thinking ahead is critical. Ask yourself the hard questions. Will your family grow in the coming years? Are you considering purchasing an electric vehicle?  

How Much Roof Space Do You Have?

We can only fit as many solar panels as possible in the space on your roof. Solar panels are typically 1.7m × 1m in size. 

It is critical to consider shading when calculating the size of your roof. Tree or power lines can cast shade on a portion of your roof. In that case, we’ll need to adjust your solar system or avoid these areas entirely.

How Much Money Do You Want To Spend?

The larger the solar system, the higher the cost. As a result, the size of your solar system will be determined by your budget.  

Like any other product, budget solar panels are less expensive than tier 1 panels. However, it is never worth sacrificing quality for lower-cost solar panels.  

A solar system is a 25-year or more long-term investment. Purchasing quality solar panels that will last for a long time should not be negotiable. 

Find more information about the payback period for a solar system here. 

What is Your Primary Goal in Installing Solar Panels?

Solar energy abstract concept vector illustration.

Some people purchase solar panels primarily to save money. Others are motivated by the wish to become more energy independent or by environmental concerns.  

Your motivation for going solar may influence the number of panels you require. For example, invest in a more extensive solar system to be self-sufficient. And you’ll also need a battery to use solar power all day and night.

Compare Panel Efficiency and Types

Solar PV is classified into monocrystalline, polycrystalline, and thin film. Each has a different efficiency rating as well as a different price point. You need to consider which solar panel system has high efficiency. 

Monocrystalline cells are the most efficient because they are made from large silicon crystals. They are also more expensive. 

Polycrystalline cells are made using silicone moulds. Therefore, it is less expensive. But also slightly less effective than monocrystalline cells.  

Thin film panels are inexpensive but much less efficient than other types. 

Before purchasing a solar power system, inquire with your installer about the solar panels’ life cycle and efficiency. Check the warranty to ensure a plan that will last many years. 

Understand Your Battery Storage Options

Solar PV systems generate the most amount of energy during the day. Consider solar battery storage if you spend most of your day at work. Solar batteries enable you to store energy generated during the day when the sun isn’t shining. 

The battery capacity is measured in kilowatt-hours (kWh). If 60% of your energy consumption occurs at night, you may want a battery to store that amount. 

However, solar battery storage can be costly, so consider a feed-in tariff system to get the money back.  

Lifestyle changes can help reduce your nighttime energy usage. For inspiration, check out our guide on how to get the most out of solar. 

How Many Batteries Will You Require?

This is an interesting question. Solar batteries for homes actually depend on your goals for your solar batteries. Most people set out to reduce their grid electricity imports to zero.  

As you’ll see, most households have big energy storage goals with more expenses. But how many solar panels run a house? “What size solar battery do I need” is a natural question you ask yourself.  

Let’s go over how much energy storage an average Australian household will require. 

The average Australian home consumes approximately 16kWh of electricity per day. Please read this if you need clarification on the difference between a kW and a kWh – it is critical). 

Most Australians work 9 to 5 jobs and are not at home during the day. They will probably only use about 30% of their electricity when the sun shines.  

That means they must buy the remaining 70% from the grid. How many solar batteries will be required to cover that 70%? 

Solar Battery System Sizing

Regarding system sizing, battery sizes are measured in kilowatt-hours, or kWh. 

As mentioned before, an average home consumes 16kWh of energy. And 30% of the energy is consumed in the daytime and 70% at night. That mounts up to approximately 5kWh consumed during the day and 11kWh consumed at night. 

Based on simple maths, the average Australian would require approximately 11kWh of solar battery storage to offset all their night usage. 

As of February 2023, the Tesla Powerwall 2 has a capacity of 13.5kWh, costing around $16,600 fully installed.  

Remember that you do not need batteries to offset your nighttime electricity consumption. If you run the numbers, the first kWh of energy storage has the best payback because it works the hardest. As of the next kWh, the payback becomes longer.  

However, the most important consideration when sizing and comparing solar batteries is that it is only possible when you thoroughly understand your energy usage profile. First, you’ll need a good energy monitor in your home with accurate data. 

Then, a good installer will use their software to show you the optimal number of batteries and solar panels for your situation and the payback period. After that, instead of leaping into the unknown, you’ll go into your solar battery investment with your eyes wide open.

How Long do Lithium Solar Batteries Last

how long do lithium solar batteries last
Solar batteries are the most valuable and rewarding addition to your solar setup. Among many kinds of solar batteries available in the market, like lead-acid and flow batteries, Lithium-ion batteries are considered to be the superior choice. The return on investment in Li-ion batteries is promising, which is why many solar battery companies and EV companies are gravitating towards it.
Now the question is, how long do lithium solar batteries last? Generally, Li-ion batteries are capable of providing you with sufficient backup for 5 to 15 years, depending on the brand, build, and how you have been treating the battery. So, it’s safe to assume once you invest in high-quality solar batteries, you can expect them to be by your side for a minimum of 10 to 12 years on average.
If you are wondering about battery backup in case of a power outage or a blackout of several days, then there are many attributes to take into account in this instance. How big the battery is and what you plan to run using the battery is what will shape the figure in hours of battery backup.

Brief Discussion on How Li-ion Batteries Work

For your ease of understanding, let us discuss the battery on a cellular level in its simplest form. So, in its simplest form, Li-ion battery, the anode (negative side) is made out of graphite, and the cathode (positive side) is made of lithium metal oxide, which is the essence of this battery. Both the anode and cathode are submerged in an electrolyte which in this case is lithium salt. Also, there is a separator in between, which helps in the exchange of electrons.
how long do solar batteries last
While the entire system is up and running, positive ions of lithium flow through the electrolyte to the negative side of the system to the anode to form a bond with the carbon of that side. While this is happening, an electron gets released in the cathode side as a reaction to what’s happening as a whole. So, the lithium metal oxide is now a lithium-ion, metal oxide, and a stray electron. This is what happens at the cellular level when you are charging the lithium cell.
Now let’s see what happens when you discharge electricity from it, AKA using the battery. At this stage, the electron flows in the opposite direction, which is basically what electricity is. A load is connected at this point of discharge, and the flow of electrons keeps the battery working.
Li-ion batteries are generally considered better despite being a tad more expensive than others because they are-
  • Smaller in size
  • Easy to maintain
  • Has a greater DOD (Depth of Discharge)
  • Offers more generic cycles to go through
  • Has a longer lifespan
  • Capable of fast charging

How Long Do Lithium Battery Last in a Blackout – Solar Battery Backup

On average, every Australian household that opts for a solar battery goes for no less than a 10kW battery backup option, which can provide your family with sufficient electricity for an entire day during a power outage. Here is a breakdown of the exact kilowatt-hour usage of a lithium solar battery if used strategically throughout a 24 hours span. Click here.
But if you opt for a battery even bigger, you can go for longer without a grid connection. Off grid homes are the epitome of an example of how a battery backup, along with solar panels, works in synchronization to run a household without any utility grid connection. The battery is charging as you use it or not to form a seamless flow of electricity in such cases.

Factors that Influence Solar Battery Lifespan – Dod

solar battery lifespan
Every battery on the market has a Dod (Depth of Discharge) percentage that the manufacturer advises. Dod is the maximum amount of solar battery that can be used before it has to be recharged. The more Dod, the longer you can go without charging the battery. If your 10kW solar battery, for instance, has a 95% Dod, you may consume around 9.5kW of the electricity before plugging it back in.
You can use the entire battery at once, but you must follow the manufacturer’s instructions to keep it in excellent condition and extend its lifespan. Otherwise, this costly investment won’t provide the greatest results possible.
More and more individuals are converting to home batteries as technology improves because they are capable of storing excess energy that is produced by fully green sources like solar panels, hydropower, and wind. Being self-sufficient with a home battery is the best approach to eliminating your carbon footprint and becoming totally energy-independent.

How Long will a 10kw Battery Last – Household Energy Basics

How long will a 10kw battery last
Imagine going a day or two without using any power sources; even an hour without electricity feels like a lifetime! That is dreadful! Well to be honest with the rising power prices and increasing political tension between the multiple nations it’s a risky take to not opt for a 10kW battery backup as soon as you can. Likewise, with the availability of government refunds it is simpler now, but there is no assurance for it to be accessible tomorrow! On that subject, how big a battery should you opt for? How long will a 10kW battery last? These are all legitimate questions, therefore we attempted to summarize them for you in this article.

How Many Hours of Backup Can I Get During Power Outage?

An average household uses up to 750W to a 1000W of electricity during a blackout or power outage situation; assuming they are only using what is necessary to keep things up and going. In that case a 10kW AKA 10,000W battery has the ability to back you up for 10 to 12 hours at a stretch. If you don’t draw power constantly then count an hour or two extra in that time crunch.
However, there is something extremely crucial to understand in this conversation. You will be spending a good amount of money purchasing a 10kW battery, so I assume you would expect that to last at least the max guarantee years. To achieve so, you are going to have to abide by some the manufacturers guidelines to keep your battery alive and well for a long time.
how long will 10kw battery last
All the batteries in the market come with a Dod (Depth of Discharge) percentage which is recommended by the manufacturer. Dod refers to what percentage of the solar battery you can use up before recharging it again. The greater the Dod the more of the battery you can use before recharging. For example, if your 10kW solar battery has 95% Dod, that means you can use about 9.5kW of the power before plugging it back in.
You can use up the whole battery at a go, but in order to keep it in good shape and increased longevity you have to abide by the manufacturer’s rules. Otherwise, this expensive of an investment will not be delivering the best it can. Remember, frequently charging and discharging the solar battery will significantly shorten its lifespan.

A Realistic Example – A Days Consumption

For instance, you are experiencing a blackout. You have a 10kW battery with 95% Dod, that means the optimum kW of energy for you to use now is 9.5kW. In this case, let us look at an example of how and where you can use this power.
  • Medium radiator (heating source) uses 1200W and hour meaning 1200*4=4800W 4hrs a day
  • Three 11W LED lights is 33W an hour and 33*12= 396W for the night time
  • A 400L refrigerator uses 68W an hour which is 68*24= 1632W a day
  • A large flat screen TV uses 100W and hour which is 100*3= 300W for a movie and more
  • A vacuum cleaner uses 1200W an hour and I guess that suffices
  • A warm wash cycle in the washing machine uses about 900W of electricity
  • Miscellaneous use let’s say its 500W for power points to charge your phone
In total that comes to 9728W or 9.7kW approximately watts day being very generous in terms of electricity use. Pretty sure vacuuming during a power shortage situation will probably not be your top priority but we still included that in the calculation to paint a realistic day in most of ours lives.
So, How long will a 10kW battery last? You can see a 10kW battery is more than enough to run your household smoothly for a day if you fully charge it once.

How Long Do Solar Batteries Last | Solar Battery Lifespan

How Long Do Solar Batteries Last
Due to the advancements of recent government rebates and many energy-saving projects, adapting to the renewable energy lifestyle is becoming the new normal. In that train of thought comes the idea of getting solar batteries. Solar batteries are the single most awesome addition to your rooftop solar that can double the benefits of having solar overnight!
Now that I have made it clear that getting solar batteries is something you should be considering, there are other attributes of a battery that you should know. Not all solar batteries will serve you equally, and even getting solar batteries now will not make sense for every household. So, before making the commitment getting to know about them should be your no.1 priority.

How Solar Batteries Work

When the sunlight hits the silicone-made solar panels, they start making electricity from direct sunlight and pass that through a solar inverter to transform the generated electricity into a usable form. Strictly technically speaking, there is no true end or pause of the electricity generation of PV panels until they hit their expiry date, which is like 25 years and 30 for some brands.
solar battery australia
Without solar batteries, the additional electricity generated by the panels will be exported to the grid, against which you will get Feed-in-tariff. Fit rates are generally not very charming. In that case, solar batteries are added to the solar system. They store that surplus of power for you to use when the peak demand hours charge a lot to import power from the grid. Saves you a lot of money in comparison to what you will make through Fit.
Getting batteries also aligns with the government’s recently developed Peak Demand Reduction Scheme (PDRS), to be inaugurated on 1st November. PDRS focuses on reducing energy usage at the peak hours of the day by incentivizing the installation of efficient gadgets and more. You can do your part by using energy-efficient gadgets and relying on battery units as opposed to the utility grid for a change. This change saves you money and saves mother nature in the long run, too; it’s a win-win situation for everyone.

How Long Do Solar Batteries Last

After purchase, a high-quality solar battery system should provide you with support for the next 15 years. However, there are batteries on the market that have an 8-to-10-year lifespan but are less expensive. To be honest, there is no reason to settle if you are considering investing in solar batteries in the first place. Because it is an investment, if you combine it with a high-quality solar system, clearly, it can give you free energy for as long as it lasts.
There are also many types of solar batteries which serve you at different capacities and run for a different number of years. The most popular types of solar batteries are lithium-ion batteries and led acid batteries.

Lithium-Ion Battery

lithium-ion battery technology is preferred by battery companies because of its greater DoD (Depth of Discharge), dependability, capacity to store more energy for a longer period of time, and smaller size. However, lithium-ion batteries are more costly than lead-acid batteries owing to their advantages.

Lead-Acid Battery

Since they have been available for so long, lead-acid batteries—which employ the same technology as the majority of automobile batteries—have been extensively used as in-home energy storage units for off the grid power choices. Although they are still available on the market at reasonable costs, their popularity is dwindling because of their poor DoD and short lifetime.

Solar Battery Cost- Would This Break My Bank?

Each kWh of solar battery storage used to cost between $3000 and $3600 for the battery alone, without including installation fees. For each kWh of solar battery storage, you may currently expect to pay between $1200 and $1400. Prices have dropped by almost 52%, and things can only get better from here.
Does this mean solar batteries are now affordable? Not really, but the benefits of having a battery backup system more than outweigh the expense.
However, just like any other category, there are also luxury brands of solar batteries. But in this aspect, these brands tend to provide and outdo the competitors in many cases which come, you guessed it, at a price. For example, Tesla batteries. Tesla’s solar battery cost can easily defeat others in the category in terms of being expensive.
Additionally, there are several key factors to consider to make when purchasing solar batteries, including the battery’s kind, compatibility with your solar panel system, brand, and installation company.
Most of them will have an impact on the price range.
