Know Your Solar System – How Does Solar Energy Work

Knowing the basics of how the solar system works will always work in your favor during the installation process and decision-making as a whole. The solar system is a package that consists of solar panels, solar inverters, and sometimes solar batteries as well.
Silicon, one of the most prevalent elements on earth, is used to make PV systems. Different silicon kinds and alignments are used to create various types of solar panels – Monocrystalline and polycrystalline solar panels. The monocrystalline solar panel, which is produced using silicon ingots rather than silicon pieces assembled into a panel like the polycrystalline ones, is the most widely used and better form of solar panel.
A solar inverter is then attached to the solar panels, converting the DC (Direct Current) power produced by the panels into AC (Alternating Current), a type of energy that can be used in your home.
solar for beginners
Your daily activities require the generated electricity, while the excess power is returned to the utility grid. In exchange for your contribution to the grid’s energy, you receive power credits that you may utilize at any time of day. A grid-tied system can always acquire electricity from the grid, just like it always did, if you don’t have enough credits or generated electricity to power your home.
The difference is that today, as opposed to in the past, you pay far less for the electricity you borrow from the grid. It’s a whole other ball game for those who have solar batteries. In that case, you can ditch the grid entirely and live on your solar system completely. Of course, in that case, you will need to have an equally excellent solar system that is not going to be cheap. But hey, you are never going to have to pay a single dime for your power bill while living a carbon-free life.

What is the Basic Cost of Solar?

The initial cost of solar depends on so many external variables if you are looking for a figure in total. But, if you are looking for prices of the panels only, $3000 is a good starting price for a quality solar panel; however, as we said before, it depends on a lot more.
For example, a bigger house requires more power, thus more solar panels to provide for the needs. A bigger family with more members to cater to will also have a greater demand for power. What about the future? Are you going to expand your family? Do you have any changes planned for the future? Let’s say in 5 years; your life can change for the better and drastically. Would the system that you are choosing right now be able to keep up with you then? Solar panels generally have a lifespan of 25 to 30 years. That is a long time, and to get the most out of your system, you have to take these little things into consideration.
As industry experts, we know the challenges of installing solar and how to work through those as we have been doing this for a good ten years. If you would like to know how you can enjoy the benefits of solar minus the hurdles, claim a free consultation session with us today.

Can I Add a Battery to My Solar System

Can I Add a Battery to My Solar System
With a vast majority of the population opting to go solar to retaliate against the increasing power bills and grabbing the opportunity of declining solar battery prices, it’s safe to say we are heading in the right direction. Many of us already have rooftop solar, and in an attempt to get the most out of the solar system, adding a solar battery should be on top of our priority list. Kudos to you, as you are already thinking about it, judging from the fact you are here in the first place.
So, the topic of discussion is, can I add a battery to my solar system if I wish to? The short and simple answer to that is yes, yes, you can. However, there are some things that you need to double-check before you think about it. Although solar battery prices are indeed falling, they can’t just be labeled as something cheap, not yet.
Before we jump to that, it’s essential to know the basics of how solar battery works.
adding solar battery with panels

How Solar Battery Works?

There are two types of solar battery storage systems to consider when on the topic. One is AC coupled, and the other is DC coupled solar battery.
In an AC-coupled system, solar panels produce DC power, which is then converted into AC electricity via a solar inverter. Your house appliances may then get this AC power, or it may go to another inverter, which will convert it back to DC so that it may be stored in a battery system. Any power that is stored in a battery system for AC-coupled systems must be reversed three times before it can be used back in the house.
On the other hand-
A DC-coupled system means that there is no inversion of solar power from DC to AC and back before the electricity is stored in the battery. Instead, DC solar electricity flows from solar panels to a charge controller that immediately feeds into a battery system. Any solar-generated electricity will only undergo one inversion (from DC to AC), either when it travels from batteries to your home’s electrical system or out to the power grid. With a DC-coupled system, your house is inevitably dependent on the battery for its primary source of energy if not connected to the grid.
Besides that, built-wise, there once again are several types of batteries available in the market. For instance, nickel-cadmium batteries, flow batteries, lithium-ion batteries, and lead-acid batteries. Because of their low cost, lead acid batteries are by far the most common option among all of these battery kinds. However, they need regular maintenance and are vulnerable to damage if not handled carefully. Lithium-ion batteries, on the other hand, are also growing in popularity lately.
Now that you are familiar with the basics of solar batteries, here is a list of things to check before you can add a battery to your solar system-

Existing Solar Inverter Compatibility

As discussed above, there are two types of solar battery storage systems which work in two different ways. Just like the batteries, there are different types of inverters that do the energy conversion of solar-generated DC electricity differently.
Your existing solar inverter can be a hybrid inverter or a standard inverter. In case you have a standard inverter, you are going to have to go through a bit more trouble. I will explain everything; bear with me.
DC VS AC coupled solar battery
You see, a standard inverter is only capable of converting DC to AC for the house to use. So, when you have a standard inverter, there are about two ways you can go by. The first option is to get rid of this system and add a charge controller, which can regulate the solar energy into going to the battery first, and tie it with a battery inverter that will supply electricity to your house. Needless to say, this is quite the expensive route to take as charge controllers that are able to take such a huge load are not cheap.
The second route to take, in case you have a standard inverter, is to opt for an AC-coupled system. This way, your system remains the same; it just gets an addition of a hybrid inverter with batteries. In this scenario, when the grid is down, the hybrid inverter steps up to keep the entire thing up and going. Without the hybrid inverter, your solar system will shut down if the grid goes down, but with the addition of the hybrid inverter, the sine waves produced by it trigger the standard inverter to keep on generating electricity, which then gets stored in the battery bank. Also used in the house.
Then comes the situation where you have a hybrid inverter. In this case, adding the battery bank will be a breeze as this one is equipped to convert both ways. Thus, saving you the hassle of getting to figure out the whole thing once again.
However, there still remains the question of how much load the inverter is able to handle and so many other things. For all these calculations and figuring out, I believe it’s best to just leave things to the professionals.

Budget

With a minimum value, you can get yourself a working battery or an amazing one. You have to figure out what your needs are and take into consideration your area, your future demands, etc.; with the calculation of everything, you have to map out a budget for the solar battery. There are many companies, including us, who can sort you out a financial plan; also, there are government rebates to help you become energy independent.

Should I Get Solar Battery for My Solar Panel?

should i get solar batteries for my solar panel
One out of four households in Australia has rooftop solar panels in today’s date. Can you guess why people accepted this change with open arms? To get away from the rising electric bills, of course. Also, with the prevalence of solar rebates at the federal and state level altogether, it made perfect sense for you and I to go solar. Because who wouldn’t like the opportunity to save money while saving nature at the same time, right?
Apart from all those good things, do you know what can make this investment even more fruitful? Adding a solar battery storage system to the whole deal. “But aren’t solar batteries expensive?” this is exactly what you might be thinking to yourself. Well, that is not incorrect, but aren’t cars expensive? What about a house? But we still invest in those assets, don’t we? Just like that, getting a solar battery is also an investment that goes a long way if you make the right calls at the right time.
It sounds a bit confusing with just that much information so let me help you out by answering your question, ‘should I get solar battery for my solar panel’ a bit elaborately.

Your Household Electricity Needs

The first step to figuring out if you should go for a solar battery is to know how much electricity you use on a regular day. Calculating that is simple; all you have to do is take a look at your electric bill copy. There you can find a breakdown of your average use in Kilowatts.
solar battery
For an average household of two people, the total consumption of electricity quarterly can be around 950kWh to 1000kWh, with 10kWh to 15kWh daily peak usage. This comes down significantly with the addition of solar panels on the roof and totally disappears with the addition of solar batteries. Since the batteries store electricity for you to use at your convenience, you will be using what you generate through the panels, scratching the grid altogether, and paying zero electric bills.
There is so much more to figure out in this scenario, but with the right assessment and experts working on your property, it’s totally plausible.

How Much Electricity Do My Panels Generate?

Assuming you already have rooftop solar panels, how much electricity they generate is a huge factor to consider. With a smaller solar system that barely fulfills your needs during the day, adding a battery will not be the brightest idea. A battery should be added to such PV systems that are capable of yielding a significant amount of energy.
However, there is an exception to the scenario.
If your area is prone to blackouts, or you get charged a stupidly high rate for energy bills, getting solar batteries in such cases is the optimum thing to do.
Also, if there is room for expansion of your solar array in case you have a smaller system, it’s a smart move if you do so. Because in the end, solar panels are the best way to generate electricity rather than depending on the grid.

When Do I Need Electricity the Most?

Let’s say you do have a smaller solar panel system. As we know, solar panels are able to generate the most electricity during peak hours, which are around 10 am to 3 pm. If you are not around the house at that time, which most people usually aren’t because of work or school, the entire amount of energy generated by even that small system of yours will be exported to the grid. Earning you Feed-it-tariff credits in the process, if applicable, but the credit you get in return is quite insignificant judging today’s market.
What can you do in this case? Get solar batteries so you can store the electricity produced by your panels in the peak solar hours. This way, you will have electricity stored in the batteries to use when the price of grid energy is high. Essentially using free energy when grid users are paying high prices.

Price of Solar Battery

Recent decreases in solar battery prices are the result of major technological advancements and the availability of resources. Naturally, that doesn’t imply they are suddenly inexpensive, but the decrease is astonishing. A kWh of solar battery storage used to cost anywhere between $3000 and $3600 only for the battery, without including installation. For each kWh of solar battery storage, you can now anticipate paying between $1200 and $1400. It will only get better from here on out—and that’s a price reduction of about 52%.

How Long Do Solar Batteries Last?

A quality solar battery system should back you up for the upcoming 15 years to come after purchasing. But there are also batteries available in the market which last 8 to 10 years, but they cost lesser in comparison. To tell you the truth, if you are planning to invest in solar batteries, there is no need to settle for less; as I already told you, it’s an investment. An investment that can provide you with free energy for as long as it last, obviously, if you pair it up with a quality solar system.
Additionally, by switching to green energy, you not only save a ton of money but also drastically lower your carbon footprint and inspire others to do the same. It’s a crucial measure to protect the next generation from the dramatic and catastrophic effects of global warming.

Power Generator VS Solar Battery Storage | Which is Right for You?

Power Generator VS Solar Battery Storage
If you live in an area that faces frequent power outages having a backup power source always can give you peace of mind. To keep running your power outlets, you need backup options in the form of power generators, solar batteries, etc.; however, there always remains confusion about whether you should go for a diesel-powered generator or solar battery storage unit.
There are some advantages as well as disadvantages of both options. Depending on your household and expectations from your backup power, you must make the call on which one is right for you. In order to make the decision, you need all the right information, and here is a brief discussion on the topic-
But first, let’s get to know how power generators and solar batteries work.

Power Generators

A diesel/power generator, usually referred to as a Genset, is a piece of machinery made up of an electric generator/alternator and a diesel engine. Together, these two components transform diesel fuel into electrical energy. Most standby diesel generators provide reinforcements. If your power system fails during a storm or the busiest time of the day, they are designed to turn on and supply you with electricity.
Two types of generators are available, one is permanent, and the other is portable. The core difference between the two is mainly their capacity. Also, their maintenance and price point are contrasting for obvious reasons.
power generator
There are also other non-renewable fuel-run generators in the market, such as propane, natural gas, gasoline, etc. As these power generators run on fossil fuels, they will work if there is fuel to power them. However, they also have their limitations and only can serve you so many hours as your specific model of the generator can push too. Overuse of such machines can be dangerous for you and the machine itself.

Solar Batteries

Solar batteries are energy storage systems that are designed to store the surplus amount of energy that is generated by your solar panel system. Your rooftop solar continuously generates power as long as the sun is shining. You consume solar-generated electricity as the day passes by to do stuff around the house all day, but a quality solar system can generate more electricity than you can use in a day. Where does that excess energy go, then? It either gets exported back to the utility grid, or you can store it in a solar battery.
Solar batteries are smart pieces of technology that not only understand when and how much to store after your household needs are met but also, in the case of an off the grid solar system, can sense when to trigger the power generator to work in case of sunlight unavailability. Furthermore, solar batteries also remain in constant communication with the solar inverter to understand when to store energy. The entire process of running and using solar batteries is seamless and hassle-free. And the best part is, you don’t have to interfere; it does everything necessary by itself, unlike power generators.
As the batteries rely on non-renewable sources like solar, there is essentially no cost of running for them. You don’t need anything else but a plentiful supply of sunshine for the batteries to be full, of course, using solar panels.

Difference Between a Solar Battery and Power Generator

Here are some core differences between both-

Reliability- power supply and quality

Generators often provide lower-quality energy that is vulnerable to power surges and other problems that can harm electronic devices like computers. They frequently require manual startup, indicating that their power source is not continuous (unless you have an automatic switch installed on a permanent generator.) Home batteries can be configured to offer a smooth backup power source that starts up in milliseconds after an electrical loss. Also, less vulnerable to surges and disruptions are home batteries.

Labour and maintenance

Solar batteries can charge themselves; on the other hand, you must refuel your generator once or twice, even thrice a day, if needed. Additionally, households using generators must store conditioning chemicals, all of which must be maintained outside and might be hazardous.

Backup hours – runtime

If your generator has fuel, it will run itself. However, the possibility of the machine getting overworked and turning useless is also high. Solar batteries, on the other hand, can run without you worrying about them breaking down, but if your solar panels fail to yield enough energy to charge the batteries, that can be troublesome. Although, it is a rare case, especially for quality solar panel system designed by the experts.

Carbon emission

As the generator solely relies on non-renewables like gas, diesel, propane, etc., it’s inevitable for the generators to not emit harmful GHG gases. In contrast, solar batteries run on renewables which means zero carbon emissions.

Cost of running

In the case of solar batteries, there is only an upfront and a one-time cost of purchasing and installing the unit. After that, you can expect to sit back, relax and enjoy the amazing perks of solar batteries. There might be occasional maintenance expenses which are rare when the unit reaches old age. Batteries run on free energy generated by the panels, and the source is our mighty sun.
The scenario is completely different for power generators. With the ongoing political tension and issues between major nations, prices of fossil fuels have skyrocketed. After you pay to purchase the generator, there will always be a recurring expense of buying fuel. So, it’s safe to assume generators cost more to run. Learn more about the price hike here.
In conclusion, if you are looking forward to an investment from which you can reap benefits for years to come and be carbon neutral, solar batteries are the way to go. Although purchasing generators is cheaper, the hassle that comes with them, not to mention the cost of running them, does not seem appealing to most.

Do Solar Batteries Work in A Blackout

Do solar batteries work in a blackout
Solar panels are an amazing addition to any household in becoming energy independent.
Adding a home solar battery to your system can potentially make you invincible when it comes to blackouts.
Do solar batteries work in a blackout? Yes!
However, your solar batteries won’t function unless you have blackout protection. And there are other attributes that may or may not allow your solar system to function during such an event.
This might sound a bit complicated, so let me explain your options to stay connected to a power source even during a blackout.

How Do Solar Batteries Work?

Solar batteries are storage units of backup power on which you can rely in the event of a power outage or at night when the solar panels can’t produce electricity. Whether it is a grid-connected system or an off grid system, you can have solar batteries added to both of them. However, when offered a high Feed-in-tariff (pretty rare nowadays), solar owners tend to gravitate towards exporting power to the grid instead of storing it in the battery, losing power autonomy in the process.
solar batteries
A typical solar storage system usually stores the surplus of energy generated by the solar panels. The surplus being whatever energy is left after your average household needs are met. Solar panels can generate more than what you need if the system works at its peak potential, you have an oversized system, or simply because you are a light energy consumer and for many other reasons.
The point of having solar batteries is to keep you connected at all times. There are several types of solar batteries available in the market for you to choose from. For instance, there are nickel-cadmium batteries, flow batteries, lithium-ion batteries, and lead-acid batteries. Because of their low cost, lead acid batteries are by far the most common option among all of these battery kinds. However, they need regular maintenance and are susceptible to damage if not treated properly. Lithium-ion batteries, on the other hand, are also growing in popularity lately.

Blackout Protection Mode- Home Solar Batteries

In order for solar batteries to continue working and provide you with energy, you have to have blackout protection mode. No, not every solar battery comes with a blackout protection mode; there are specific batteries that either have it or they don’t. For this, you have to have a chat with your solar battery installers.
Let’s imagine ourselves in one of these situations to get to understand the concept a tad better.
Suppose you are connected to the grid, and suddenly your area experiences a blackout. The first thing that will happen is your solar panels will stop working, meaning the solar panels will stop feeding energy to the solar inverter, thus having no power in the outlets. This is true if you have a grid-connected system without solar batteries or batteries without blackout protection mode.
blackout backup with batteries
It happens for the sake of the safety of the people working to fix the issue that caused the blackout in the first place. If the grid-connected solar panels keep on generating energy, then the possibility remains that the surplus will be exported back to the grid, being fatal for the workers.
In such a scenario, your solar batteries will get the signal of the blackout within seconds. Depending on the type of battery and how it works, the time delay may vary. As mentioned before, to trigger the blackout mode, your batteries need to have a blackout protection mode. Only then the stored energy will flow back to the house.

For How Long Can You Depend on Solar Batteries During a Blackout?

There are two things that can happen in a situation like this.
First, your solar batteries will only be usable till the point they run dry. This is simple; whatever much energy is left in the batteries, you will get only that much to work through. As the panels have already stopped working for safety purposes, there is no more energy to store for later. Point to be noted; this also depends on the blackout protection mode provided with your batteries. Depending on the battery manufacturer, your blackout protection mode will be able to handle a different amount of load. Some can handle up to 7kW, while other batteries can go only to 2.5kW.
In a different scenario, you can go for days with a quality solar system paired with a top-notch battery in case there is a blackout. For this to happen, your batteries need to have the functionality to let the solar panels keep working in such events. Of course, without exporting any energy back to the grid.
It goes without saying that with an off the grid system, a blackout has no effect on your life. As going off the grid means being energy independent and self-sufficient. It’s the ultimate protection from power outages, blackouts, and outrageous electricity bills at the end of the quarter.

Should I Get a Solar Battery Storage System

should i get a solar battery storage system
Frequent power outages, unreliable grid connection, low feed-in-tariff, and high electric bills, can you relate to these frustrating issues? If yes, then without a doubt, a solar battery storage system is the solution to your problems. Besides, if you have an outstanding solar panel system yielding a ton of energy, the surplus of which you are exporting to the grid in exchange for a low FiT, you can surely go for a solar battery.
In short, to answer your question, should I get a solar battery storage system the answer is yes, for the most part. However, in certain circumstances, it’s also not necessary to go for a battery; all of those, along with the pros and cons of solar batteries, are discussed below.

What Am I Missing Out on Without Solar Batteries?

To tell you the truth, you are missing out on the best bit of having solar panels. Renewable sources of energy like solar, hydro, and wind makes us feel empowered with their ability to exterminate our carbon footprint, not to mention the low electricity bill. Along with those good things, we also have the opportunity to sustain on our own, at least for power which is a massive deal. But without batteries, it’s next to impossible to become energy independent.
solar battery storage system
Without a Battery storage system, you are missing out on-

Free Power Backup on Demand

Solar batteries store the excess amount of energy generated by your solar panels to be used at a later time. But in case of irregular cases like your solar panels struggling to generate enough energy, you can use the battery at will. Also, when you conserve excess solar energy, you can use it at night when the electricity prices are higher because of high demand.

Being Self Dependent

You have gone through the trouble of installing solar panels on your rooftop. The goal is to generate as much energy as possible through this source to not stay dependent on the grid. When your panels are able to satisfy your needs and do more, it gives you the perfect opportunity to ditch the grid for good. Making you self-sustained and worry-free.

What Size Battery Do I Need?

I believe you recognize by now how solar batteries can be amazing at serving us with more power independency. So, that brings us to the question of how big of a battery would suffice your needs. The answer to this question solely depends on you and your family’s needs. There is no one-size battery that will make financial or functional sense for everyone.
Nevertheless, if you have an average family of four with no exceptional power demands, you may get by with a 10kWh to 12kWh battery bank as a ready-to-roll backup system. I repeat, this is just an estimation with no knowledge of your power needs; selecting a battery is highly subjective to the household in question.
With that being said, you can get a good idea of how much power you use on average by analyzing your electric bill copy. Also, keeping track of what appliances you use the most and what requires the most power will help you. I would suggest leaving that to the professionals as the chances of getting the wrong numbers are high with a do-it-yourself approach, and solar batteries are just too expensive to make an error.
solar battery price

How Much Do Solar Batteries Cost?

Previously, you would have to pay between $3000 and $3600 for the battery alone, plus the cost of installation, for every kWh of solar battery storage. Currently, you may anticipate paying between $1200 and $1400 for each kWh of solar battery storage. That is a price reduction of approximately 52%, and things will only get better from here.
Does that imply solar batteries are cheap now? Not really, but the cost is well justified by the pros of having a battery storage system.
Also, while paying for solar batteries, you have to counter in many other factors like the type of battery, your solar panel system configurations and compatibility, brand, and installation partner. These will influence the price range for the most part. Learn more about the cost of solar batteries here.

The Pros and Cons of Solar Battery at a Glance

I won’t blame you if you feel a little overwhelmed about making a decision because I understand it’s a tough one. So, here is a list of pros and cons of having a solar battery to help you in the decision-making process-

Pros

  • Solar batteries help you become self-sustaining
  • You don’t have to care about power outages anymore
  • In the event of any natural disaster, you will still have a power source
  • Battery prices are dropping significantly as we speak
  • During peak hours, grid electricity prices increase due to high demand; you can avoid paying a high price and use your battery. It’s essentially free energy as solar generates energy from the sun.
  • Reduced carbon footprint as the battery stores energy from a renewable source.

Cons

  • Batteries can be expensive, and that is the only weakness I can point out. Nonetheless, any investment comes at a price, and it depends on you whether or not that investment makes sense for you.
In conclusion, if you should get a solar battery storage system depends on your energy usage pattern, your living condition, your area etc. But as a general query, getting solar batteries to tie with your solar panel system is the best approach in your energy independence journey.

How Much are Solar Batteries | Cost of Battery

how much are solar batteries
Adopting renewable energy sources like solar, wind, hydro, etc., as the primary energy feeder for a household is the best possible way to become carbon-free. However, if you want to completely eliminate your dependency on the grid and receive zero electric bills at the month’s end, solar batteries are the way to go.
Solar batteries are amazing; there is no room for doubt. Although, the pros of having a battery attached to your solar system is a clear win. Still, the question remains, how much are solar batteries? Here’s a brief discussion.

Price Range of Solar Batteries

Prices of solar batteries have dropped down recently due to significant improvements in technology and the availability of resources. Of course, that doesn’t mean they are cheap now, but the drop is astounding. Previously for each kWh of solar battery storage, you would have to pay somewhere around $3000 to $3600 for battery only plus the installation cost. Now, you can expect to pay about $1200 to $1400 for each kWh storage of solar battery. That’s almost a 52% price drop, and it will only get better from here onwards.
solar battery price
To make more sense out of those numbers, imagine a typical family of four. With no extraordinary power usage on average, they would require about 38kW to 40kW to live comfortably. Assuming they are not connected to the grid and have solar as their sole energy source, the majority of that power need will be satisfied with direct solar power. They will only require extra when the sun doesn’t shine, and that can be compensated with solar batteries. That power need can be assumed to be around 12kWh to 15kWh. Note that I am being generous with numbers here; you might not even need this much for a family of four.
Assuming that the family is in need of a 12kWh battery depending on power, that will cost them around 12kWh*$1200= $14,400 to have solar batteries tied with the solar system. Yes, by no means is that a small number, but you have to consider its advantages. Also, don’t forget it is an investment to yield benefits for the upcoming ten years at a minimum with zero electric bills. Now that sounds like a fantastic deal, doesn’t it?

What Influences Solar Battery Cost?

Type of Battery
Many types of solar batteries are available for grabs in the Australian market as we speak. Different battery types come with different pros and cons. However, there are two most popular types used for solar energy storage, which are-
  • Lead-acid battery
  • Lithium-ion battery
Lead acid batteries are cheaper in comparison and are the most popular type of solar battery at the moment. However, they are not the most efficient option out there, as they require regular maintenance. On the other hand, Li-ion batteries are seemingly better alternatives to lead-acid ones as they require little to no maintenance, charge faster, offers a greater DOD (Depth of Discharge), and so much more. But it’s to be noted that li-ion batteries cost more than lead acid batteries.
Installation
Cost is also dependent on installation as that is also a factor that adds more to the initial number. A certified and insured solar installer should oversee the installation of solar batteries, which is non-negotiable in order to achieve power independency. Making modifications to your current solar power system yourself can jeopardize the battery, and the system, so a do-it-yourself approach is discouraged by solar emporium unless you are an approved installer yourself, of course.
With the installation process comes labor cost, and this is also a factor that varies from person to person, depending on the installation site and the work time.
solar battery cost
Size
Of course, the size of the battery hugely impacts the cost. If you want more hours of battery backup, the battery will be more expensive, and vice versa.
Brand
Certain brands are expected to cost more because of the superior quality offered by them, along with the faith that comes with those brand names. For example, a Tesla powerwall will definitely cost you more than any other battery brand for its brand value, and outstanding quality claimed by the company. Other renowned brands also follow the same agenda.
Inverter Type
If you already have a solar system installed on your rooftop, you definitely also have an inverter. Depending on the type of inverter, the cost of the battery may increase as a whole. If you do not have a battery-ready hybrid inverter, your cost of having a battery will significantly go up as you are going to have to get a brand-new inverter with the system.
But that is not the only way around, you may get away with additional wiring and small changes around the solar system, but that is strongly subjective to your inverter type.
So, those are the factors that influence the cost of the battery. Please note that along with these factors, the numbers may fluctuate depending on your needs and your house. To be precise in this journey, and save money in the long run, it’s easier and best to consult with an expert in the field. Also, if you want to claim government rebates, all of your components and installation partners need to be CEC (Clean Energy Council) approved.

How Long Do Home Batteries Last

How long do home batteries last
Home solar batteries are the only way for anyone to become completely energy independent. In a circumstance where you are connected to the grid, you don’t have the authority to dictate your power usage and may lose access to it due to issues that are out of your control. A solar battery grants you complete control of your power usage, making you self-reliant.
And, of course, home solar batteries are an absolute necessity for an off the grid household.
With that comes the question, how long do home batteries last? Do solar batteries last as long as solar panels? Let’s find out.

Home Solar Battery Lifespan

On average solar batteries have a lifespan of 5 to 20 years. Although that depends on many external factors like the type of battery, full cycle usage, dependability, warranty and more. But you can expect your home solar battery if installed correctly and in good condition to serve you for at least 5 to 20 years.
home solar batteries
Within the lifespan of the battery, there are two stages of that in which the battery backup capacity is divided. Which are-
Useful Life of Battery- A solar battery has a limited number of uses before reaching the end of its “useful life.” When a battery falls short of meeting around 60% of its nominal storage capacity, it is generally considered to have reached the end of its usable life. At lower percentages, the battery could still be able to work, but it probably won’t supply enough charge to fulfil your needs.
Warranty Period for the Battery- Your solar battery’s warranty specifies how long it will be operating properly under typical circumstances. The warranty length can range from 10 to 20 years, depending on the brand and model of solar battery you buy, with the majority being set at 10 years from the date of installation. A solar battery’s warranty typically ends when it fulfills one of three criteria.
  • Expiration of the warranty
  • Reached capacity (throughput)
  • Number of allocated cycles reached

Factors that Effect Solar Battery Lifespan

Battery type- There are many battery types available for solar energy storage. For example, Lead-acid batteries, lithium-ion batteries, flow batteries, nickel-cadmium batteries etc. Among all these battery types, lead acid batteries are by far the most popular choice because of their economical price point; however, they require regular maintenance and are prone to damage if not handled with care. On the other hand, lithium-ion batteries are also becoming popular recently.
Because Li-ion batteries 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
Despite the performance difference, lead acid batteries are still the most popular choice at the moment. But in future, the scenario might be in favor of the Li-ion batteries as there are many car manufacturing companies adopting to this change for the better. And the solar industry is also gravitating toward the shift because of the increased benefits.
Maintenance- It’s important to check up on your home solar batteries once in a while to make sure they are operating at their peak performance. Some type of batteries requires less assistance than others.
Full cycle number– When your home solar battery is fully charged once and drained entirely is considered one entire cycle. How many times one has repeated this cycle is a determining factor of how long will the battery last. Depending on whether you live on or off the grid, the number of cycles a day will drastically change.
Heavy usage Vs light usage- How many cycles you get from your battery will depend on your usage, and that can affect the battery life, as previously mentioned. So, if you decide to run a few appliances and light up your house using the battery, you expect to run through fewer full cycles per day. On the other hand, if you are a heavy user and run power-hungry appliances on the battery, you will run through more cycles, and your battery lifespan may decrease.
home battery lifespan
Home batteries are getting adapted by more and more people as the days go by. As they are capable of storing the surplus of energy generated by the completely green source, e.g., solar arrays, hydropower and wind. In order to become completely energy independent and to remove your carbon footprint, becoming self-sufficient with a home battery is the way to go.

What is a Solar Inverter | Solar Inverter 101

what is a solar inverter
If you are looking forward to getting your own solar PV system, I’m sure you know by now that a solar system consists of at least two crucial pieces of mechanism. The first is the solar panel itself, and the second is a solar inverter. Solar panels are essentially silicon plates that can generate electricity if exposed to sunlight. (Read more on that- here)
So, what is a solar inverter? Simply put, solar inverters make it possible for us to use the solar power generated by the panels. Otherwise, solar panels only can provide us with DC (Direct Current) electricity which is not consumable by regular appliances. What solar inverters do is convert that DC electricity into AC (Alternating Current) electricity, which is a usable form of energy.
In-essence it converts DC to AC by rapidly shifting the direction of a DC input. A DC input becomes an AC output as a result. Filters and other electronics can also be used to provide a voltage that fluctuates as a clean, repeating sine wave and can be fed into the power grid.

A Little History of Solar Inverters

Solar inverters were around back in the 19th century, and it wasn’t popularized until the 20th century. Most of its major modifications and improvements were introduced later on. But if we were to credit someone for gifting this incredible technological piece of wonder to mankind, that would be Nikola Tesla. He was a famous scientist back in the day and still is a legend in scientific history.
Previously, rotational motors were used to alternate between connecting the DC source forward and backward. Today, transistors are used to construct electrical switches, which are solid-state devices with no moving components. Thus, a smoother operation with cooperatively less hassle.
If you have a home solar system, your inverter most likely serves multiple purposes. It can monitor the system and provide a portal for connection with computer networks (WIFI, ethernet) in addition to converting solar energy into AC electricity. If the system allows, solar-plus battery storage systems rely on modern inverters to run without any grid backup during outages.

Types of Solar Inverter

There are many types of solar inverters performing one core task while differing in their ways of achieving the goal and some additional benefits. Here is a brief discussion on several types of solar inverters –

String Inverter

String inverters are the most popular and oldest form of solar inverter. It is a simple type of solar inverter that connects all the solar panels in a single string to the inverter. In this category, ‘N’ numbers of solar panels are linked together in a series, with a single string connected to a single string inverter.
They are the most affordable type of solar inverter. With a system so straightforward, it is extremely easy to install and maintain the entire system.
string inverter
However, they have a drawback. Since all the solar panels are linked to the inverter via the same chord, the entire PV system’s performance deteriorates if a single panel faces shading issues. Also, your options for future expansion are limited with string inverters unless you buy a whole another inverter. In this case, upsizing the system and going for a larger capacity inverter is the smartest move.
Nevertheless, string inverters are tried, tested, and trusted by the majority of Australians.

Microinverter

This is a comparatively new-gen inverter that overcomes the hindrance of string inverters. Microinverters are small inverters that are installed at the back of each solar panel. This removes the threat of the entire string suffering from shading issues for a single panel and lets each solar panel work individually.
Like the regular inverter, it also performs the core task of converting DC to AC for us to use. Rather than converting the entire solar system, a microinverter converts DC to AC for a single panel. This ensures maximum power generation and elevated efficiency for the entire system combined.
micro inverter
Please note that microinverters are comparatively expensive. Because of their high efficiency and complicated mechanism, they are priced higher than other types of solar inverters. However, if you are a homeowner who is looking for the best outcome without worrying about the budget, you can give microinverters some serious consideration.

Hybrid Inverter

This is an extremely popular type of inverter among solar enthusiasts. If you live in an area that is notorious for frequent power outages or the sun exposure isn’t quite as reliable in your exact solar space, this one would be an ideal choice.
Hybrid inverters do connect in a series like your regular string inverter, but it works smartly. To paint a clearer picture, let us suppose you are generating about 600 watts of energy from your solar array but your load, or your need for the time being, is about 1000 watts. Your regular inverter would seek power from the external battery bank, and if that doesn’t suffice, it will take in electricity straight from the grid. However, that isn’t the most efficient choice.
What a hybrid inverter does is it takes in all it can from the panels and the battery bank, which is within the inverter itself, and then it goes out to seek power from the grid. Nothing is wasted; you only take however much you need. This way, you are less dependent on the grid, thus reducing your overall power bill.

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 system

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.

Solar battery ROI

The return on investment (ROI) for solar batteries in Australia is influenced by various factors, such as the system’s initial cost, local electricity rates, solar generation capacity, and available government incentives or rebates.

Key considerations include the upfront expenses encompassing the battery, inverters, installation, and related components.

The cost of grid electricity in your area is pivotal, with higher rates potentially leading to faster returns, as stored solar energy use during peak periods saves on electricity bills.

Solar panel efficiency, battery performance, and lifespan also impact long-term returns. Government incentives, rebates, and electricity consumption patterns, especially during high-demand periods, contribute to overall ROI.

Monitoring technological advancements is crucial for assessing the economic viability of solar battery systems over time.

Seeking professional analysis and staying informed about industry trends and policy changes are advisable for making well-informed investment decisions in Australia.

Look for reliable brands and models with proven performance and longer lifespans. Ensure compatibility with your existing solar system, and check for government incentives or rebates. Compare the cost per kilowatt-hour and warranty terms.

Consider factors like installation requirements and whether the battery supports backup power. Seek professional advice to tailor your choice to specific needs and conditions.

State Rebates for Solar Batteries

State rebates for solar batteries vary across Australia. States like South Australia, Victoria, and Queensland offer specific incentives and rebates for solar batteries.

However, rebate programs and amounts can change, so it’s crucial to check the latest information from your state government or relevant authorities for the most up-to-date details on solar battery rebates.

Solar Battery FAQs

The size of the solar battery needed to power a house in Australia depends on various factors, including your energy consumption, the size of your solar panel system, and your specific energy needs.

On average, a medium-sized household might require a solar battery with a capacity ranging from 5 kWh to 20 kWh.

To determine the appropriate size, consider your daily electricity usage, the sunlight your location receives, and whether you want the battery to provide backup power during outages.

It’s advisable to consult with a solar energy professional to assess your specific requirements and design a system that meets your energy goals.
