Understanding solar energy savings and how they work

Solar panels convert sunlight into electricity, which can then be used to power your home. During peak sunlight, your solar system generates more electricity than you might need. Without solar battery storage, this excess energy is typically fed back into the grid, and you may receive a small feed-in tariff.

However, this excess energy is stored for later use with a solar battery system, maximising your solar energy savings.

How solar energy helps reduce electricity bills

1. Generating free power from the sun

Solar panels generate electricity from sunlight, allowing households to power their homes with free, renewable energy. During daylight hours, solar panels can significantly reduce reliance on grid electricity, leading to substantial solar energy savings.

2. Net metering and feed-in tariffs

If a solar system produces more energy than needed, excess electricity can be fed back into the grid in exchange for credits through Australia’s feed-in tariff programs. This further reduces electricity costs and improves overall savings.

3. Reducing peak hour dependence

Electricity rates are typically higher during peak demand hours. With a well-designed solar system, households can use solar energy daily and store excess energy for later use, minimising reliance on expensive grid electricity.

Solar battery storage allows businesses and homeowners to store unused solar energy generated during the day and use it at night or during cloudy periods. This ensures a continuous power supply and enhances solar energy savings.

2. Lowering peak demand charges

For households on time-of-use tariffs, battery storage helps avoid drawing power from the grid during peak pricing periods. Instead, stored solar energy is used, leading to significant cost reductions.

3. Providing backup power during outages

Battery storage systems also serve as a backup power source during blackouts. This added reliability ensures uninterrupted power supply while reducing long-term reliance on grid electricity.

Solar battery storage cost benefits: Is it worth the investment?

One of the most common concerns for businesses and homeowners is the upfront cost of solar battery systems. While the initial investment can be substantial, the solar battery storage cost benefits often outweigh the expenses in the long run.

Decreasing battery prices

The cost of solar batteries has steadily decreased due to technological advancements and increased market competition. Government incentives and rebates further enhance affordability.

Long-term savings

With rising electricity prices, battery storage helps businesses and homeowners lock in lower energy costs by storing and utilising their energy. Over time, these savings offset the initial investment, making it a cost-effective solution.

Australia is one of the sunniest places on Earth, making it an ideal location for harnessing solar energy. Solar power offers several benefits:

Reduced electricity bills: Solar panels generate electricity from sunlight, reducing your reliance on grid electricity and lowering your electricity bills.

Environmentally friendly: Solar power is a clean and renewable energy source, helping reduce your carbon footprint and contributing to a more sustainable future.

Government incentives: The Australian government provides various incentives, such as Small-scale Technology Certificates (STCs) and feed-in tariffs, to encourage solar adoption.

Energy independence: Solar power allows you to generate electricity, reducing dependence on the grid and safeguarding against power outages.

The role of solar batteries

While solar panels generate electricity daily, excess energy is often returned to the grid or wasted. Solar batteries, also known as energy storage systems, store this surplus energy during the night or when the sun isn’t shining. They play a crucial role in maximising the benefits of solar power.

Determining whether a home solar battery is right for you

Assess your energy usage: Begin by evaluating your household’s energy consumption. Analyse your electricity bills to understand your energy consumption patterns and identify peak usage times.

Solar panel efficiency: Consider the efficiency and output of your existing solar panels. If you have older or less efficient panels, upgrading to newer ones could significantly impact your energy production.

Energy storage needs: Determine the excess energy your solar panels generate and whether it can meet your energy needs during cloudy days or at night. The larger your surplus energy, the more valuable a solar battery will be.

Battery cost: Solar batteries come with an upfront cost, varying depending on capacity and brand. Compare the cost of batteries against potential savings over the long term.

Feed-in tariffs: Check your local utility’s feed-in tariff rates. If the rate is low, it may be more cost-effective to store excess energy in a battery and use it when needed rather than selling it back to the grid.

Government incentives: Be aware of any current government incentives, grants, or subsidies that may help offset the cost of purchasing a solar battery.

Battery lifespan: Consider the expected lifespan of the solar battery. High-quality batteries can last for many years, ensuring a better return on your investment.

Installation and maintenance: Factor in the installation and maintenance costs. Ensure you have a reliable installer with a good track record.

Calculating potential savings

To determine whether a home solar battery will result in cost savings, you can perform a simple financial analysis. Calculate the following:

Battery cost: Calculate the upfront cost of the battery system, including installation.

Energy savings: Estimate the amount of energy you can store and use from the battery each day.

Electricity savings: Determine the reduction in your electricity bill due to using stored energy instead of drawing from the grid.

Payback period: Calculate how long it will take for the energy savings to offset the initial investment.

Return on Investment (ROI): Assess the overall return on your investment by comparing energy savings to the total cost of the system.

If your payback period is within 5-7 years, then a home battery is likely a good financial investment for you. However, if your payback period is longer than 7 years, then a battery may not be the right investment for you at this time.

Here are some additional factors to consider when deciding whether or not to purchase a home battery

Your electricity tariff: If you are on a time-of-use tariff, you can save more money with a home battery by using stored solar energy during peak periods when electricity prices are highest.
Government subsidies: The Australian government offers several subsidies for home batteries, which can help to reduce the upfront cost of the system.
VPP participation: If you participate in a virtual power plant (VPP), you can earn money by allowing your battery to be used to provide electricity to the grid at times of peak demand.
Blackout protection: Home batteries can provide backup power during a blackout. This can be a valuable feature if you live in an area that experiences frequent power outages.
Environmental benefits: Home batteries can help to reduce your reliance on fossil fuels and your carbon footprint.
Future plans: If you are considering switching to an electric vehicle in the future, a home battery can help you power your car and save money on fuel costs.
The cost of the battery: Home batteries can range in price from several thousand dollars to tens of thousands of dollars. The cost will vary depending on the size and capacity of the battery, as well as the brand and model.
The warranty on the battery: Most home batteries come with a warranty of 10-15 years. However, it’s important to read the warranty carefully to understand what is and is not covered.
The maintenance requirements of the battery: Most home batteries require very little maintenance. However, it’s important to have the battery inspected by a qualified technician regularly.

Overall, whether or not a home battery can save you money will depend on your circumstances. However, if you have a high electricity bill, a solar panel system, and a time-of-use tariff, then a home battery could be a worthwhile investment.

In Australia, installing a home solar battery should be based on a comprehensive analysis of your energy usage, panel efficiency, battery costs, government incentives, and potential savings. While solar batteries can result in significant cost savings over time, it’s essential to carefully evaluate your specific circumstances to determine whether they are a worthwhile investment for your family. With the right approach and conditions, home solar batteries can provide a sustainable and economically viable energy solution for Australian households in 2023 and beyond.

Why solar storage solutions matter for Australia

Australia’s solar boom has created both opportunities and challenges. One significant challenge is managing the energy generated by solar systems when demand doesn’t align with production. Solar panels generate the most power during the daytime when the sun is shining, but energy use often peaks in the evening after the sun has set. This mismatch between energy generation and demand is where solar storage solutions, particularly solar batteries, come into play.

Some benefits of solar battery storage

Batteries capture excess solar power generated during sunny periods and store it for later use, offering homeowners and businesses a range of benefits:

Balancing the grid: Solar batteries in Australia can store excess solar energy generated during the day and release it at night or when needed, helping to balance the grid and reduce reliance on fossil fuels.
Reducing costs: Solar batteries can help reduce the need to upgrade infrastructure to cope with peak demand, saving consumers and businesses money.
Increasing reliability: Solar batteries can provide backup power during outages, improving the electricity supply’s reliability.
Enabling renewable energy: Solar batteries can enable renewable energy sources such as solar and wind power by storing their output and releasing it when needed.
Reduced greenhouse gas emissions: The battery will help to reduce reliance on fossil fuels for electricity generation. This will help the state meet its emissions reduction targets and contribute to the fight against climate change.
Job creation and economic benefits: The construction and operation of the battery will create jobs and boost the local economy.
Participation in Virtual Power Plants (VPPs): Virtual Power Plants (VPPs) are gaining traction in Australia. They allow households with solar batteries to aggregate their stored power and feed it back to the grid during high-demand periods. Participants in a VPP can earn incentives by selling excess power back to the grid, which benefits the broader community by enhancing grid stability.

The Future of Solar Batteries: When Will They Be Affordable in Australia?

April L — Mon, 02 Oct 2023 07:10:44 +0000

Abundant sunlight and an emphasis on renewable energy make Australia a hotspot for solar power adoption. One in three homes across the nation have rooftop solar panels, harnessing the sun’s energy to power homes and reduce electricity bills.

As the world shifts toward a greener future, another technology has begun to capture many Aussies: solar batteries. These energy storage systems promise to revolutionise how we use solar energy, allowing households to store excess power for use during the night or during grid outages.

But there’s one lingering question on the minds of many: When will solar batteries become affordable in Australia?

Cost trends of solar batteries in Australia

The average price of home solar batteries is between $1,000 to $13,000 per kWh of capacity installed. However, the price varies depending on the brand, size and location.

In the early stages of solar battery technology, the cost was undeniably high. They were primarily the domain of early adopters and those with a solid commitment to reducing their carbon footprint. These early systems were expensive to purchase and install, which limited their accessibility to many homeowners and businesses.

The good news is that the landscape has changed significantly in recent years with the cost of solar batteries steadily decreasing. Advances in battery technology have led to higher energy density, longer lifespan, and improved efficiency that help make solar batteries more cost-effective.

The demand for solar batteries also continues to grow, hence more manufacturers and suppliers have entered the market. As a result, it increased the competition that drives down prices, which makes solar batteries more affordable for consumers.

A solar panel owner can benefit more from solar battery ownership as the net benefit has increased from 0.15-0.20 $kWh in 2020 to an average of 0.24 $kWh in 2021. The trend is expected to continue as solar feed-in tariffs (FiTs) and export charges are introduced.

Insights on when prices will drop

Sunwiz has released its annual Australian Battery Market Report, which showed significant growth in residential battery energy storage systems (BESS). In 2021, Australia added 47,1000 installations, which brings the country’s cumulative total to 180,000 ESSEs since 2015.

Nearly all Australian states are added to this number except for South Australia (SA), which has approximately 7 per cent of the nation’s total 26 million residents as of September 2022.

This accounts for a surge in renewable energy that is causing a considerable drop in average prices with $83 per megawatt hours (MWh) in the first three months of 2023, according to Australia’s National Electricity Market (NEM).

This makes Australia one of the most attractive markets in the world for BESS technology, which paves the path for diverse revenue streams that drive the viability of BESS.

To gain better insights into when the prices of solar batteries will drop in the country, there are various factors to consider that influence the cost of solar batteries.

Advancements in technology

Manufacturers of solar batteries are continually researching and developing new materials and designs to boost the efficiency and lifespan of energy storage. As advancements in technology become more widespread, the cost of producing solar batteries is expected to decrease.

Manufacturing scale

As the demand for solar batteries increases in the country and globally, manufacturers can produce batteries in larger quantities, leading to lower production costs per unit. This is one of the trends that are already evident as more companies enter the market and expand their production capabilities.

Market competition

With the growing interest in solar batteries, it attracts numerous players to the industry, which leads to intense competition. To gain a competitive edge, manufacturers and suppliers are under pressure to offer more cost-effective solutions.

Government policies and incentives

A lot of states and territories offer financial incentives, rebates, and FiTs to encourage the adoption of renewable energy technologies. As these policies persist and evolve, they can significantly reduce the upfront costs of installing solar batteries.

Energy storage research

Research institutions and universities in Australia, and across the world, actively study energy storage technologies. Their findings can lead to breakthroughs that make solar batteries more cost-effective.

Consumer demand

As more Aussies recognise the benefits of solar batteries, demand is likely to increase further. Higher demand can stimulate innovation, drive competition, and lead to cost reductions as manufacturers strive to meet the needs of the market.

Whilst the cost of solar batteries has been steadily increasing in recent years, predicting an exact timeline for when they will become highly affordable is challenging. However, the consensus among experts is that prices will continue to drop over the coming years, making solar batteries increasingly accessible to a broader range of consumers.

Therefore, individuals who want to pursue solar batteries should keep a close eye on market developments, government incentives, and technological advancements.

Emerging technologies in the field of solar batteries

One of the emerging technologies today in energy storage is the use of machine learning and artificial intelligence. These technologies can improve the performance of solar batteries by optimising, managing, and forecasting.

Hybrid energy storage systems are also emerging. This type of system mixes various technologies, such as thermal storage and batteries.

The potential for off-grid solar systems to revolutionise the affordability of solar batteries

Off-grid solar systems deliver an independent and self-sustaining source of electricity for homes. They consist of solar panels, batteries and inverters that allow homeowners to generate and store energy without relying on the grid. This autonomy from the grid is a game-changer for affordability.

Excess energy is stored in batteries for later use with off-grid systems that maximise self-consumption, ensuring that homeowners use as much of the energy generated by their solar panels as possible.

In many parts of the country, solar panels owners benefit from FiTs. However, they are typically lower than retail electricity rates. With off-grid systems, will let residents reduce their reliance on FiTs by using stored energy during peak demand times when grid electricity is most expensive.

Off-grid systems also prioritise battery storage, and as the demand for solar batteries increases, economies of scale come into play. As more homes adopt off-grid systems, the production of solar batteries is likely to increase, leading to lower costs per unit.

Whilst off-grid systems may need a higher upfront investment compared to grid-tied systems, their long-term affordability benefits are appealing. This revolution in energy indolence offers a promising path for households in Australia to embrace renewable energy and reduce reliance on costly grid electricity.

It’s evident that the future holds great promise for the affordability of solar batteries in Australia. As advancements continue, we can anticipate further drops in costs, enhanced efficiency and increased accessibility for homeowners and businesses alike.

Tesla Powerwall 3: What We Know and When it Will Be Available in Australia

Nicole S — Sun, 10 Sep 2023 22:00:00 +0000

The renewable energy industry is abuzz with news that the Tesla Powerwall 3 is not only in the works but has been installed on a few properties in the USA!

Little has been known about the Powerwall 3, the next generation of the Tesla Powerwall battery series. Industry insiders have been scrambling for details for months, but news of the recent installs has confirmed many rumours and put to rest wild theories and expectations.

What do we know about the Tesla Powerwall 3?

The Tesla Powerwall 2 has been a top seller since its inception in 2016. Featuring 13.5kWh of storage capacity, the home battery has been a favourite for its features and name. The Tesla Powerwall 3 is expected to be much the same as its predecessor, though with improvements to its maximum power output. The company’s CEO, Elon Musk, re-shared on X (formerly Twitter) the recent installations on 3 homes. He also confirmed that the Powerwall 3 will be optimised for ‘ease of installation and high power’.

PW3 is optimized for ease of installation & high power, which means that a single Powerwall can serve as an uninterruptible power supply for most homes.

This is a big deal for ensuring that the lights stay on and you can power all your devices in the event of a power outage.

— Elon Musk (@elonmusk) September 8, 2023

Shared on the Tesla Motor Club were some details from the installation, including photos taken of the unit itself and the specifications.

It can also be assumed, though not confirmed, that the battery will also serve as an inverter. If confirmed, this would be incredible news for homes looking to purchase a new solar system. A separate inverter would not be necessary, which would cut down on the overall cost of the system (battery + solar). We assume that this will be the case as the pictured installation of the Powerwall 3 shows that the unit includes a rapid shutdown for PV, which is a feature designed for inverters and not batteries.

What we don’t know:

While the recent news has given us some insight into what we can expect from the Powerwall 3, there are still many details that we are uncertain about:

Whether the pictured Powerwall 3 will be available in Australia or there will be a variant
When the Powerwall 3 will be available for Australians
Whether the battery will have inverter integration
The cost of the system
Warranty period

For the time being, we will need to look across to the USA for news on the Tesla Powerwall 3. However, the recent discounts offered by Tesla for the Powerwall 2 would indicate that the production of the unit will be tapered for the release of the Powerwall 3. Like all things Tesla, we can expect an upcoming unveiling that will deliver all the information we need.

Solar Battery Storage Buying Guide: How to Make the Right Decision

Beth P — Mon, 04 Sep 2023 00:00:00 +0000

In an era marked by the increasing demand for clean and sustainable energy solutions, solar power has emerged as a frontrunner in revolutionising how we generate electricity. As the adoption of solar panels becomes more mainstream, the importance of efficient energy storage solutions, like solar batteries, cannot be understated. Solar batteries play a crucial role in harnessing the sun’s power, storing excess energy, and ensuring a consistent power supply. This comprehensive guide aims to navigate the complexities of solar battery selection tailored to your unique needs.

How a solar battery works

Solar batteries, also known as solar energy storage systems or solar battery storage, are devices designed to store excess energy generated by solar panels during periods of high sunlight. This stored energy can be utilised during cloudy days, nighttime, or when energy consumption exceeds the solar panel’s immediate output. Solar batteries bridge the gap between energy generation and consumption, enabling homeowners and businesses to optimise their solar investments.

Solar panels generate electricity during the day.
The solar inverter converts the electricity into DC (direct current).
The DC electricity is then stored in the solar battery.
At night, or when the solar panels are not generating enough electricity, the battery can provide AC (alternating current) electricity to your home.
The battery inverter converts the DC electricity from the battery into AC electricity that your appliances can use.

AC versus DC coupling

AC coupling and DC coupling are two different ways of connecting solar panels to batteries. In an AC-coupled system, the solar panels are connected to an inverter, which converts the DC power from the panels to AC power that the home or business can use. The inverter also charges the batteries. The solar panels are connected directly to the batteries in a DC-coupled system. A charge controller is used to regulate the flow of power between the panels and the batteries.

AC-coupled systems are generally easier to install than DC-coupled systems. They are also more common in Australia, as they are compatible with the grid-tied solar system. However, AC-coupled systems are less efficient than DC-coupled systems, as they lose some power during the conversion from DC to AC.

DC-coupled systems are more efficient than AC-coupled ones but are more complex to install. They are incompatible with the grid-tied solar system, so they are only suitable for off-grid systems.

So why install a solar battery storage?

Consider a household consuming 20 kWh of electricity per day. With a 10 kWh solar battery, the household can store excess solar energy generated during the day for consumption at night or during power outages. This can significantly reduce reliance on the grid, potentially slashing electricity bills by up to 80%.

Businesses can also reap substantial benefits from solar batteries. A commercial establishment with a 50 kWh battery can store excess solar energy to power operations during peak demand hours, reducing reliance on expensive grid electricity. This can lead to significant cost savings, improved energy efficiency, and enhanced environmental sustainability.

Here are some benefits of using solar batteries in Australia:

Save money on electricity bills

Solar batteries can help you save money on your electricity bills by storing excess solar energy during the day and using it at night or during peak demand times.

Reduce your reliance on the grid

Solar batteries can help you reduce your reliance on the grid by storing solar energy that you can use when the grid is unavailable or when electricity prices are high.

Increase your energy independence

Flow battery

This type of battery uses liquid electrolytes to store energy. They have a long lifespan and can be used for solar and wind power applications, but they are also the most expensive type of battery.

Nickel-cadmium battery

This type of battery uses liquid electrolytes to store energy. They have a long lifespan and can be used for solar and wind power applications, but they are also the most expensive type of battery.

Sodium nickel chloride battery

The newer battery type is still under development. They have the potential to be more efficient and less expensive than lithium-ion batteries, but they are not yet widely available.

What is a virtual power plant and what does it have to do with a solar battery?

A virtual power plant (VPP) is a network of distributed energy resources, such as homes with solar and battery systems, that are centrally managed to provide electricity to the grid. VPPs can help improve the grid’s stability, reduce reliance on fossil fuels, and provide financial benefits to participants.

In Australia, several VPPs are already operating, including the AGL Virtual Power Plant, the EnergyAustralia PowerResponse VPP, and the Solar Victoria VPP Pilot Program. These VPPs are helping to make Australia’s energy system more reliable, sustainable, and affordable.

If you are considering installing a solar battery in Australia, consider joining a VPP. This can help you maximise your battery’s benefits, such as reducing your electricity bills and helping stabilise the grid.

Here are some benefits of participating in a VPP in Australia:

Reduce your electricity bills: By participating in a VPP, you can use your battery to store solar energy during the day and discharge it back into the grid at night, when electricity prices are higher. This can help you to reduce your electricity bills.
Help stabilise the grid: VPPs can help stabilise the grid by providing backup power during peak demand or outages. This helps ensure that everyone has access to reliable electricity.
Earn income: Some VPPs offer participants the opportunity to earn income by providing their battery storage to the grid. This can offset the cost of your battery.

Solar battery rebates and VPPs – making batteries more affordable at a cost

The cost of solar battery storage systems in Australia has steadily declined in recent years, but they are still a significant investment for many homeowners. Solar battery rebates and virtual power plants (VPPs) can help to make batteries more affordable, but they also come with some costs.

Solar rebates are government or utility incentives for a financial discount on purchasing a solar battery system. VPPs are groups of homes and businesses that connect their solar batteries and other distributed energy resources to the grid. VPP participants can earn money by providing services to the grid, such as storing energy during peak demand or providing backup power during outages.

Solar rebates and VPPs can make batteries more affordable, but they also come with some costs. Rebates may be limited to certain types of solar batteries or homeowners meeting certain eligibility criteria. VPP participants may be required to pay a monthly fee or to make their batteries available for grid services at certain times. Learn more about Solar Battery System Rebates, Subsidies, & Incentives.

FAQs | Frequently Asked Questions

Are solar batteries worth it in Australia?

In Australia, several key factors influence solar batteries’ value proposition. Firstly, the rising cost of electricity has made the self-consumption of solar energy more attractive, increasing the potential savings from solar battery storage. Secondly, Australia’s high sunshine hours and generous feed-in tariffs for excess solar energy can reduce the payback period for battery investments.

Despite these advantages, the upfront cost of solar batteries remains a significant barrier for many households. Additionally, the effectiveness of battery storage depends on individual energy consumption patterns. Those with high evening energy usage are more likely to benefit from solar battery storage than those with lower evening consumption.

Besides financial considerations, solar batteries offer several non-monetary benefits, such as enhancing energy independence during power outages and reducing reliance on the grid. They also contribute to a more sustainable energy future by maximising the utilisation of renewable solar power.

Overall, the decision of whether solar batteries are worth it for Australian households depends on a range of factors, including individual circumstances, financial considerations, and energy consumption patterns. Carefully evaluating these factors can help homeowners determine if a solar battery system aligns with their needs and budget.

How to choose solar battery size?

Choosing the right solar battery size for your Australian home can be daunting. There are many factors to consider, such as your household’s energy consumption, budget, and future energy needs.

Household energy consumption: This is the most important factor when choosing a solar battery size. You can find your average daily energy consumption on your electricity bill. Once you know your average daily consumption, you can choose a battery that can store enough energy to power your home for at least one or two days.
Budget: Solar batteries can range in price from a few thousand dollars to tens of thousands. It is important to set a budget before you start shopping for batteries.
Future energy needs: If you plan on adding appliances or making other changes to your home that will increase your energy consumption, you will need to choose a large battery to meet your future needs.

As a general rule of thumb, a 10kWh battery is a good starting point for an average Australian household. However, you may need a larger battery with high energy consumption. Conversely, you can get away with a smaller battery with low energy consumption.

What size solar battery system do I need?

The size of the solar battery system you need in Australia will depend on a number of factors, including your average daily energy consumption, your desired level of self-sufficiency, and your budget.

Average daily energy consumption: The first step is determining your daily energy consumption. You can do this by checking your electricity bills or using an online energy calculator. The average Australian household consumes around 18kWh of energy per day.
Desired level of self-sufficiency: Once you know your average daily energy consumption, you can decide how much you want to rely on your solar battery system for your energy needs. If you want to be completely self-sufficient, you will need a larger battery system than if you are only interested in reducing your reliance on the grid.
Budget: Solar battery systems can range in price from a few thousand dollars to tens of thousands. It is important to factor in your budget when deciding on the size of your system.

Generally, a battery system with a storage capacity 10kWh to 15kWh is a good starting point for most Australian households. This will allow you to store enough energy to cover your needs during the night and on cloudy days.

Here is a table that shows the recommended battery size for different household sizes:

Household size	Average daily energy consumption	Recommended battery size
1-2 people	10-15kWh	10kWh
3-4 people	15-25kWh	15kWh
5 or more people	25-35kWh	20kWh

Of course, these are just general guidelines. The best way to determine the right size battery system for your needs is to consult a qualified solar installer.
