How much do home batteries cost?
Although most people install storage for the resilience benefit, as opposed to the financial benefits, that doesn’t mean storage costs are insignificant. In fact, depending upon the size of your solar and storage install, batteries can increase the cost of the overall installation significantly, sometimes even doubling the cost of a solar panel installation. As you consider whether or not to install energy storage, it’s important to consider the costs of batteries, as well as the two primary factors that influence those costs.

Key takeaways about solar battery pricing
- The current market price for most solar batteries ranges from 8,500 to 10,000 (not including installation). The price including full installation fees can increase to 10,000 to 20,000
- There are a number of equipment-related factors including battery quality, number, and chemistry, as well as having an inverter.
- Installation-related costs are also significant including the type of installation and if you need a critical load panel.
- Finding an installer is also a crucial part of total battery cost. The best way to compare your options with installers is on the EnergySage Marketplace today.
How much do popular solar batteries cost?
A typical home battery will usually cost between 10,000 and 20,000 fully installed on EnergySage, but that number can vary widely based on several factors. read on below for an outline of what influences home battery cost. As far as some of the more popular solar batteries available, here’s what you can expect in terms of starting pricing (for models we don’t have standalone pricing for, we’ve included estimated total costs including installation):
| Tesla Powerwall | 8,500 |
| Generac PWRcell | 9,999 |
| sonnen eco | 10,000 |
| LG Chem RESU | 9,500. 13,000 with installation |
| Panasonic Evervolt | 15,000. 20,000 with installation |
Factors that influence energy storage cost
There are a few key factors that determine how much your energy storage system will cost: the equipment you install, the electrical work required for your installation, and even where you find your installer.
Perhaps the biggest factor in the cost of a battery installation is the equipment itself: what battery are you installing and how many of them do you need; what chemistry does it use to store energy and does it have its own inverter? While equipment costs typically account for 50-60% of the cost of an energy storage system, the installation itself–i.e., the amount of electrical work required and where you find your installer–also plays a large role in the overall cost of the system.
Factor 1: the quality of your batteries
Similar to solar costs, the first thing to consider with the batteries you’re installing is the quality of the product you select. While all storage products on the market today meet rigorous safety testing requirements, there can still be variations in the overall quality of the energy storage systems and you’re likely to pay more for higher quality products.
Factor 2: the number of batteries you need
Each storage installation is unique and everyone’s storage needs are different. For the most part, storage system sizing is less flexible than with solar panel systems. It’s easy to add or subtract a single solar panel from a system design to finely tune the capacity of the install; however, with most solutions on the market, it’s difficult to finely tune the size of battery you install. As a result, the cost of storage will vary significantly depending on the kilowatt-hours of energy you need to store and, thus, the number of batteries you install.
Factor 3: the chemistry of your battery
There are a few different types of batteries available for home and business owners on the market today, though the most common ones typically use some form of lithium ion chemistry to store electricity. The two most common types of lithium ion batteries are nickel manganese cobalt (NMC) and lithium iron phosphate (LFP). Each chemistry has different characteristics–NMC batteries tend to be more power dense while LFP batteries tend to last longer–which also means they come at different costs. On EnergySage, LFP batteries are often 30-50% more expensive than NMC batteries.
Factor 4: does your battery have its own inverter?
Batteries store direct current (DC) electricity, but your home or business uses alternating current (AC) electricity, so you’ll need an inverter to convert the electricity that’s stored in your battery to usable AC electricity. Some batteries come with their own hybrid solar-plus-storage or storage-specific inverter. But if yours doesn’t, you’ll need to also purchase an inverter–or already have one–that can convert your stored energy into AC electricity, adding a cost to the overall system.
Factor 5: retrofit vs. new solar and storage
Energy storage installations require a significant amount of electrical work, and a not insignificant amount of time from your installer. As a result, if you install storage concurrently with solar, you’ll see some time efficiencies and cost savings by having all of the electrical work done at the same time and by not requiring your installer to make additional trips.
Factor 6: critical load panels
Most storage solutions on the market today aren’t large enough to cover every load in your home, meaning you’ll have to pull certain circuits onto a critical load panel. A critical load panel is like a secondary electrical panel where you put all of your essential circuits that you want to remain energized in the event of an outage. While the critical load panel itself isn’t particularly expensive, the electrical work required to install one can add up quickly.
If you’re going to have electricians pulling circuits during a storage install anyways, why not go the next step and install a Smart electrical panel to get the most out of your storage system? A number of manufacturers now offer Smart electrical panels that provide circuit-level monitoring and controls, leading to increased flexibility with how you use your solar and storage installation.
Smart electrical panels are certainly more expensive than a critical loads panel; however, the flexibility they provide in your ability to get the most out of your storage installation make them a no-brainer in most cases. Why would you decide today which appliances and circuits you want to back up for the next ten years when a Smart electric panel allows you to update those preferences in real time?
Factor 7: where you find your installer
There’s no one-size-fits-all storage solution. With that in mind, it’s important to get multiple quotes to compare the same way you’d compare for other major purchases: solar, cars, home appliances, a new HVAC system, you name it.
When you find your solar plus storage installer through EnergySage’s online quote comparison platform, you’ll pay less for solar and storage. Sign up for an account today to see how much EnergySage can save you!

Western Power may restrict inverter capacity in certain network locations to no more than 8 kW output capacity.
As solar panels rarely reach peak rated power, certain solar inverter manufacturers state that their inverters can be overloaded by up to 50%.
However, the Clean Energy Regulator has had their say on this topic and capped oversizing to 33%.
Therefore, 8 kW Inverter capacity x 1.33 = 10.64 kW of solar panels. However, certain module/inverter design limitations may influence a reduced overall capacity.
This depends on you. A 10 kW solar energy system with an 8 kW inverter will generate an annual average 45 units (kWh) per day.
However, each dwelling and energy consumption profile is unique, as unique as your finger print.
Sales support can provide detailed bill reduction estimates based on your past energy usage patterns. By using advanced software, the more past power bills you provide the more accurate your bill reduction estimate is likely to be.
Yes. However, as with all 10 kW solar systems, battery choices are limited. For example, if the only battery you want to install in the future is a Tesla Powerwall (AC coupled), then selecting any standard inverter will work.
Although, should your preference be a BYD or Sungrow SBR (DC coupled), a compatible solution would require a specific hybrid solar and battery inverter.

kW Solar System And Information
If you’re thinking of buying a 10kW solar system in 2023, then you probably have a good-sized roof and significant electricity bill! Or perhaps you have an electric car or are looking ahead to an EV purchase.
A 10kW solar system is about as big as residential systems get, practically speaking. Below is photo of an older 10kW system. There was no space left to waste on this installation! However, note this photo was taken some years ago.
Solar panels installed for 10kW systems in 2023 are significantly more efficient and pack more power into a smaller overall footprint, so not as much roof space is required as it once was. Here’s an example – still 10kW but around half the number of panels; although they are a bit larger in terms of physical dimensions:
24 x 415 Watt panels on 2 roof faces in this 2022 10kW installation.
How many solar panels will you need for 10kW?
To make up a 10kW solar system you need 24 solar panels, assuming you use 415W panels – that will give you 9.96kW.
Each panel will be about 1.8m x 1.1m, so you’ll need at least 46m2 of roof space.
To provide an idea of how much space that is, this picture may help.
How much electricity will a 10kW solar system generate?
A 10kW solar system will generate approximately 40kWh per day on average – that works out to be 14,600 kilowatt-hours a year. It’s a lot of electricity and enough to run 2-3 average Australian households; or one really inefficient household!
To put it in perspective, 40kWh per day will power:
Approx 2x ducted air conditioning systems on a hot (or cold) day.
4 small pool pumps for 10 hours per day.
40 x 5 star energy rated fridges with the freezer on top or below (not side-by-side; those suckers use a lot more energy).
How much will a 10kW solar system save on electricity bills?
The amount you’ll save on electricity bills with a 10kW system will depend on how much you get paid for exported electricity (solar feed in tariffs) and how much you self consume.
Feed in tariffs in Australia pay anywhere from 3c to 20c, depending on the state and retailer. Let’s work on 8c per kWh for exported electricity. Most people pay about 30c per kWh to buy electricity from the grid. So let’s consider 3 scenarios to see how the payback works:
1) Use all the solar electricity in your (huge) home or business: You would save approximately 4500 in the first year. But 100% self-consumption for a household is unlikely; there will be times when your 10kW system is exporting to the grid.
2) Export half the electricity: You would save about 2700 in the first year.
3) Export all the electricity: You would save about 1000 in the first year.
Moral of the story: The more solar you self consume, the faster your payback.
How much does a 10kW solar power system cost in 2023?
You should get about 3,960 in STCs (AKA the solar rebate). So expect to pay about 8,500 – 13,000 out of costs for a good quality 10kW solar system in 2023, professionally installed by a reputable installer.
That’s quite a price range – the reason is the cost of a 10kW solar system will depend on the type of components used. At the upper end of the price range it will be top of the line panels, inverter and racking installed by a particularly fussy installer. At the lower end, you should still get good quality components (but do your research). Be wary of systems below the bottom end of this price range – there can be a high cost associated with cheap solar in terms of problems down the track.
How long before a 10kW solar power system pays for itself?
Payback will depend on feed-in tariff and self-consumption, but it’s reasonable to expect a 10kW solar system (assuming it’s suitable for your situation) will have paid for itself in around 5-6 years. After that the electricity is free apart from a small maintenance cost – expect to pay a few hundred dollars every 5 years for an inspection – and a replacement inverter every 12 – 15 years.

Common questions about 10kw solar systems
Switching to solar is a serious matter and lots of concerning points pop up along the way. Here are some of the questions that we’ve received from our readers and customers.
How much power does a 10kw solar system produce per day?
The production of your system can be heavily influenced by external factors like weather, shading and positioning of your panels. Besides, different regions get different amounts of sunlight per day. For instance, a system in San Francisco gives you more energy than the same installation would in New York. You can get an approximate number for how much does a 10kw solar system produce daily by multiplying the capacity in kW by the number of peak sun hours in your area. For instance, the average number of peak sun hours in California throughout the year is 5.6. Thus a 10 kW system makes around 10 kW × 5.6 hours = 56 kW per day. Keep in mind that in summer panels produce around 50% more energy than in winter.
How many panels are in a 10kw solar system?
The number of PV modules in your system may vary depending on their wattage and size. For instance, you can build a 10 kW installation with thirty four-thirty five 300W panels or you get by with twenty 500W panels, if they are available. Generally, panels that are 300W to 380W in power capacity have 60/120 cells. These are smaller and they are more popular in residential rooftop installations. Panels that are over 400W in capacity have 72/144 cells or more. They are larger and harder to fit on a roof, that’s why they are more popular in ground-based installations.
An interesting option to consider are bifacial panels: they provide up to 33% more production from a single panel with an active rear side. The bifacial gain depends on reflectivity of a surface and it’s important to install these panels correctly.
How much does a 10kw solar system cost?
You have to take a lot of things into account when you try to estimate the expenses that your system requires. The panels that you’ll choose, the type of inverter, additional equipment, like controllers and batteries, type of installation, solar incentives that are available to you — all this impacts the final 10kw solar system kit price. Let’s briefly go over the most important points.
Solar panels greatly vary in price, efficiency, temperature behavior and warranties that they come with. The cheapest PV modules come from China. North American brands, like Canadian Solar, Silfab and Mission Solar, offer more expensive products but of a higher quality. The most advanced panels come from brands like REC, Panasonic, LG, but going for them may significantly increase your 10kw solar system cost.
Inverter is the most fragile and complex part of a solar system so it’s better to pick a good one from the start. You can choose a standard string inverter for your 10 kw solar kit or you can pick microinverters instead. They are more efficient and their monitoring capabilities are more precise, but they cost more as well. You need an off-grid inverter for an off-grid configuration or a hybrid inverter for a hybrid system, which is typically more advanced and expensive.
The way you’ll want your panel system to be constructed also matters. Ground-based installations are typically cheaper to install than rooftop ones. Grid-tie 10kw solar kit is the cheapest option: all you need are panels and inverter. Hybrid systems are slightly more expensive because they require a hybrid inverter which may or may not have a built-in energy storage. Hybrid systems sometimes pay off quicker because a battery allows you to avoid peak electricity rates of your utility. An off-grid 10kw solar system with batteries is often the most expensive option. Batteries are pricey by themselves and you need a larger energy capacity than with a hybrid system to ensure the energy autonomy of your house. Generally, you want your energy storage in a 10kw off grid solar system kit to have enough capacity to power your home for at least one day without the support of the panels. 10 kW of solar power is enough to support a large house by itself without commercial electricity.
How do you install a 10 kw solar system?
Solar systems, especially of that scale, generally need a permit from local authorities to be installed. In some states it’s a requirement that a system should be constructed by a certified contractor. Thus you should be prepared to hire one. Here are some tips on choosing the installer:
- The best way to choose an installer for your 10kw solar system kit is to have your friends recommend you someone. If it’s not an option, local authorities sometimes provide lists of contractors that operate in your area and have a good reputation.
- Ask the company for contacts of their previous customers, call them and ask them about their experience. You can also contact the Better Business Bureau and check for complaints.
- When talking to different installers, ask them how many years of experience they have and how many systems they have installed. Check their professional licenses.
- Ideally, you want to get bids from at least three contractors before deciding between them. Bids typically include the total cost of installation, specifications of your 10 kilowatt solar system, such as estimated production, based on the positioning, angle and shading.
- Before signing a contract, make sure to fully examine it and ask questions. If you’ve agreed to something verbally, it should also be written down. Seek out legal advice help if you need to. The contract should contain start and end dates of construction, the list of equipment that is to be installed, payment schedule, itemized budget with a list of subcontractors, and warranties.

How many batteries required for 10kW solar system?
When it comes to designing a solar power system, it is important to consider the number of batteries required to store the energy generated by the solar panels. A 10kW solar system can generate a significant amount of energy, but it is essential to have the appropriate number of batteries to store this energy efficiently.
To determine how many batteries are required for a 10kW solar system, there are a few factors that need to be considered. Firstly, the location of the system and the amount of sunlight it receives will determine how much energy the solar panels can generate. The number of batteries required will also depend on the amount of energy that needs to be stored and the capacity of the batteries themselves.
Typically, a 10kW solar system will require a battery bank with a capacity of between 20-30 kilowatt-hours (kWh). This is because the system will need to be able to store enough energy to power the home or business during periods of low sunlight or at night when the solar panels are not generating any energy.
The number of batteries required to achieve this capacity will depend on the specific battery chosen, as well as the voltage and amperage of the system. As a general rule, most batteries used in solar power systems have a capacity of between 100-200 amp-hours (Ah). Therefore, a battery bank with a capacity of 20-30kWh would require between 100-150 batteries with a capacity of 200Ah each.
It is important to note that the number of batteries required for a 10kW solar system can vary depending on the specific system and energy requirements. It is always best to consult with a solar power system professional to determine the exact number of batteries required for your specific needs.
In conclusion, a 10kW solar system typically requires a battery bank with a capacity of 20-30kWh, which can require between 100-150 batteries with a capacity of 200Ah each. However, it is important to consult with a professional to determine the exact number of batteries required for your specific solar power system.

WHAT PEOPLE SAY ABOUT OUR WORK
Here’s what our customers across Australia have to say about our solar system installations.
Very professional guys ! installed solar panels in a very Smart way, with good utilisation of space and design. Thank you Amazing Solar !
Patrick has been very helpful from start till end. Definitely contact him and get the amazing services.
Anna was very accommodating to my requests when discussing about configuration options. She openly laid out the comparisons in quality and price between different panels and inverters which helped a lot in making decision. When comparing with other retailers, this company also provides a great value for money. However, when it comes to the more technical side of things (e.g. how would the panels be stringed together for maximum performance, how many optimisers will be needed if at all, and which panels will get it and why), it seems that there is a bit of gap and at times a bit wanting. Installation was very quick: it was done in a day and the installer did the job well with no fuss. They were even willing to do a quick investigation and fix for a wiring issue in my garage pro bono. When the inspector came, they confirmed that everything was installed correctly and there was no issues whatsoever, which is great to hear. However, it took quite a bit of following up from my part with Amazing Solar to actually get the installer scheduled in (was promised a call in 2 weeks time, but none came until I manually followed up). This is a bit of a let down and casted a bit of uncertainty, but thankfully Anna is always available over Whatsapp to be contacted.
I spoke to Patrick who explained all my questions and guide me to apply for my rebate. The installers (Suki) and his team are very professional, not only they installed the solar, they also help me to find the plumber to disconnect my hot water solar system on the same day. Very happy with the services from the team
I had a very good experience with Amazing Solar. Peter was very patient and explained all details about the product and rebates available. I procured quotes from 2 other providers, but Peter provided a very competitive quote. Installation was also very quick and professional. Highly recommended.
Thanks Henry for helping us through the solar process. Was easy to get the installation done at Wonthaggi. Even our follow up questions were answered quickly. Would recommend people to use Amazing Solar.
Thank you Amazing Solar team, especially Peter for a great help and your service for solar installation. Highly Recommend.
