Without battery storage, any excess power produced by your solar system during the day is exported to the power grid. After dark, the panels stop making power and the home or business uses electricity from the grid.
â
However, with a solar battery storage system installed, any unused solar power generated through the day is stored in the battery for later use.
Solar panels convert sunlight into Direct Current (DC) electricity. Solar panels are installed on your roof and positioned to receive maximum sunlight. Good quality solar panels can last 25 years or more.
The inverter converts DC electricity from the panels into Alternating Current (AC) electricity, which we use in our home appliances, store in a battery or export to the grid.
Store excess electricity in your battery for use in the evening. If the battery is full, the excess electricity is fed back to the grid. A battery can also provide electricity to your home in a black out.
A smart meter is used by your electricity retailer to measure the flow of electricity in and out of your home. It sends this information back to your retailer remotely, without your meter needing to be manually read.
The grid is the network of poles and wires that carry electricity. As well as buying electricity, you can export excess electricity into the grid and get paid a feed in tariff from your electricity retailer.
The benefits of storing your own clean, free electricity are many, including the ability to:
NRG Solar can help you add a battery to any solar power system. If you have a âbattery readyâ system, it means your existing inverter can easily handle the addition of battery storage.
â
For âbattery capableâ systems, it means that a battery inverter is usually required. Some battery systems, such as Tesla Powerwall, come with an inbuilt inverter. Even older systems may be made battery capable.
âWeâll take you through a thorough discovery of your home, energy use and future goals, then provide a clear picture of your costs and savings. Â
â
Importantly, we would also take into account the effect on any existing warranties, the size of your existing system, your current feed-in tariff and other considerations.
At NRG Solar, we design and install energy storage solutions for a range of scenarios. From homeowners who want to save money and live more sustainably, to business customers who want to reduce their maximum power demand or have blackout protection.
The payback period will vary from system to system based on the system size and usage. But itâs common to see payback periods as short as four years. After that, you are enjoying free electricity for years to come. For some customers, the payback period is even shorter.
This is not only because battery storage can help to reduce the payback period on your solar panels and inverter. Itâs also because your battery system, coupled with the NRG battery monitoring app, helps to drive lifestyle changes and positive power use behaviours.
Customers using the NRG battery monitoring app save even more because they can see their system in operation and the effect of their energy use. But donât worryâyou donât have to be a solar technician!
A common misconception is that batteries will get more powerful and become cheaper over the next few years. This was certainly true five or six years ago, but unfortunately no longer the case. In fact, the last three price changes in South Australia saw the cost of battery systems go up each time.
Battery manufacturers, such as Tesla and BYD, already supply millions of batteries a year. Therefore, their investment in cost reductions through manufacturing automation and supply chain improvement has already been done. Plus, demand for their products is rising year-on-year.
Aside from savings, there are many other compelling reasons that a solar battery makes sense:
Some people choose to get a solar battery for energy security. For example, they may have medical devices, appliances or work equipment they rely on.
An increasing number of people install solar batteries for conscientious reasons. They want to reduce their environmental impact or enjoy lifeâs creature comforts without feeling guilty about carbon emissions.
Around 80-90% of all new solar power systems we install include battery storage. The growing expectation among homeowners, especially with luxury homes, is that the property is energy friendly.
Continuous electricity price rises can be infuriating. Yet another great reason to take power production into your own hands.
At NRG Solar, we know thereâs no âone-size-fits-allâ when it comes to battery storage. Every household has different energy needs, goals, and budgets. Thatâs why we work with you to design a customised solar + battery solution that delivers the best outcome for your home or business.
We offer a carefully selected range of premium battery brands â including Tesla Powerwall, BYD Battery Box, FranklinWH, Sungrow, Enphase and Sigen â all trusted names in the renewable energy space. Each brings its own strengths, from whole-home backup and smart energy control to scalable storage and robust warranties.
What they all have in common is proven performance, safety, and reliability. And when you choose NRG Solar, you can be confident your system has been designed and installed by Adelaideâs trusted solar and battery experts.
We are one of the only national recipients of the Tesla Premium Certified Installer status. Very few solar companies in Australia are recognised by Tesla at their highest level.
â
The right battery for your home or business depends on your setup and goals. Some batteries are better suited to single-phase vs three-phase power, some are ideal for new builds, while others can be retrofitted to existing solar systems.
An NRG Solar consultant will take the time to understand your requirements and walk you through how the different systems work â so you can feel confident youâre choosing the solution thatâs the best fit for your home and lifestyle.
The Australian Standard for solar energy storage installation is called AS/NZ 5139 2019. It was introduced in 2019 as an important consumer protection against fire and other associated risks.
â
At NRG Solar, we are enthusiastic about formal safety standards. Thatâs because we are also solar repair specialists. Over the years, weâve fixed thousands of orphaned systems installed by other companies. The workmanship we witness is often lazy, unskilled or straight out dangerousâthe type of negligence that could result in injuries or fatalities from fire or electrocucion.
As with all things involving electricity, the safe installation of solar batteries cannot be overstated. Thatâs why NRGâs team of installers are certified solar electricians. Plus they receive ongoing training in the latest compliance standards and technologies.
â
The NRG Solar promise is that there are no compromises on safety or qualityâand no surprisesâalong the way. You know itâs going to be done right. Youâre going to get a turnkey solution with smooth project management from start to finish.
There are of course averages, but we like to remind people that how much power you need to charge a solar battery has less to do with the number of panels on your roof, and more to do with how much surplus power your panels generate.
For some households, systems as small as 4 kW will generate enough surplus electricity through the day to be stored in a battery, while other households would need a bigger system and more panels.
The reality is that every householdâs energy use is different. This is why there is not one size of system to suit every home or business.Â
The key is to talk with an NRG Solar battery expert who can assess your energy needs and design a tailored system for your situation.
Before diving into how long a solar battery can last, letâs first look at how much electricity the average Adelaide home uses.
â
The daily average electricity usage for South Australia is 19 to 20 kWh during summer and winter, and 15 to 16 kWh in the milder months of autumn and spring. Most of that power is used in the peak hours between 5 pm and 10 pm.
â
The key time for drawing on stored energy is of course after the sun has set. This is when your rooftop panels are no longer making electricity. After dark, the average South Australian home uses around 8 kWh of electricity in the milder months and 9 kWh in summer/winter.
Now, consider those numbers against a 13.5 kWh solar battery. Assuming the battery is fully charged during the day, it will have plenty of clean, green power to keep the average home running all night!
If you were ever worried about suddenly running out of power overnight, you donât need to be. NRG Solar solutions come with a monitoring app that shows your battery reserve and usage in real-time.
â
Not only does the NRG app keep you updated about your energy reserves, it provides powerful insights into how much electricity your household uses. Most NRG Solar customers fall in love with the app and say it has a positive effect on their power use behaviour.
The Summers family in Adelaideâs Aberfoyle Park has Tesla Powerwall attached to a 7.4 kW rooftop solar system. In the evenings, they have two adults and two children at home, using the usual array of lights and appliances.
â
Jane Summers says, âI love that I can see how much power weâre using with the monitoring app. I can see when we have a surplus of solar generation and when is the best time to operate, say, the dishwasher or washing machine. Itâs definitely had a positive impact on our behaviour.â
â
Tesla Powerwall is charged to its 13.5 kWh capacity by the end of the day. On the average night, they draw around 8-10kWh of stored power. All of that is clean, green solar energy.
â
Jane says, âBefore we added the battery our power bills were manageable thanks to rooftop solar. But adding the Powerwall has increased our self-sufficiency to around 95 percent. Itâs a nice feeling to know that the grid only has to supply 5 percent of our power needs.â
â
Find out how energy independent you could become by talking with an NRG Solar consultant.
We often get asked which is better: on or off-grid solar? In fact, very few homes are truly off-grid, meaning they rely solely on self-generated power and energy storage. A true off-grid scenario is more likely to occur in remote locations where network power isnât available and almost always includes a backup petrol or diesel generator.
â
For remote customers, we would be pleased to help design an off-grid solar solution for your home or business.
When most people refer to âgoing off the gridâ theyâre talking about a desire to become more energy independent. Their property will remain connected to the retail power network, but the aim is to replace electricity from the grid with as much solar power as possible.
â
This is certainly the most cost effective way to simultaneously reduce your retail electricity bills and minimise your carbon footprint.
In fact, with solar combined with battery storage, on average we help NRG Solar customers to achieve a whopping 96% power self-sufficiency.
â
In many instances, our customers totally eliminate their power bills.

As well as power bill reductions, energy securityâor blackout protectionâis one of the leading reasons Adelaide home and business owners choose to install solar battery storage.
â
In blackout conditions, they can be assured that essential appliances, machinery, lights, telephone, security systems, internet, or other critical circuits continue working.
For blackout conditions, your battery system can be programmed to run limited circuits. The idea is to avoid large loads from power-hungry appliances, such as ovens and ducted air-conditioners, in favour of keeping lights, refrigerators, TV and internet functioning as usual.
â
In an extended blackout, some battery systems allow the solar panels to recharge the battery while simultaneously drawing electricity to power essential circuits.
â
Working with an NRG Solar consultant is the best way to design a blackout protection system that meets your needs.
The first rule of getting a solar battery quote is to approach it as an investment. That means talking with a trusted, reputable solar expert.
â
The second rule is to get familiar with solar battery language. There are some important differences between battery systems.
â
The third rule is to never buy a battery based on price alone. But first...
When it comes to solar and batteries, a quote is only as good as the process behind it.
At NRG Solar, every project starts with a thorough phone-based discovery of your home, energy use, and future goals. This ensures we design a system thatâs tailored to you â not just a generic price from an aerial photo.
In some cases, a site check is also required. This is to confirm installation details like your meter box, cable runs, blackout circuits, and safe access. These steps arenât just important for performance â theyâre essential for compliance and for keeping your warranties valid.
By combining detailed discovery with on-site checks where needed, we can give you a fixed-price, no-surprises quote and an installation that runs smoothly from start to finish.
When it comes to comparing solar battery brands and systems, there are a number of important differences. We would be pleased to sit down with you and explain how the different systems work and what to look for.
â
But for the sake of education, we would like to briefly explain here the difference between battery capacity and discharge capacity.
â
Battery capacity is how much energy can be stored in the battery. Itâs usually expressed in kilowatt-hours (kWh).
â
Discharge capacity describes how much stored energy is usable.
â
For example, a 10 kWh battery with 90% discharge capacity, will provide 9 kWh of usable energy. By comparison, Tesla Powerwall has 100% discharge capacity.
â
That extra usable capacity can have a big impact on your power savings over time and dramatically reduce your payback period.
It often doesnât take long for a cheap battery to become an expensive one. This is because the money you save upfront may be quickly eclipsed by money you lose down the track.
â
An undersized battery, for example, is easy to get overworked which means it will wear out more quickly. Focus instead on comparing features, performance and support:

Thereâs lots of reasons why you could be left with scratching your head at what went wrong. From companies who have gone out of business, through to installations that were just never met quality or safety standards.
NRG installed 4 Enphase batteries; I already had 4, and wanted to expand. Michael Summers was my main contact, and was friendly, efficient and got me a fantastic deal! The installer was a chap called Jarrad, and I was impressed at their professionalism during the installation.
Upshot is: if you are after solar and/or batteries, speak to NRG for a quality job at a good price!
My experience with NRG Solar was fantastic. From the excellent quote they gave me for my home battery system, to replies to all my queries, no matter how insignificant.
I spoke and dealt with a number of staff at NRG and, without fail, they were friendly and knowledgeable. Â Everything happened at the times and dates they said it would .
The actual installation went smoothly. The technicians were there on time  and  the system was explained to me before they left . It has worked well since then.
Had a great experience with NRG Solar. They installed Tesla Powerwall and the guys right from the beginning with Michael and Ellen, right down to the sparkies Alex and Jarrad, were brilliant.
Investing in a battery is about more than just storing power - itâs also about maximising the savings and benefits available to you. Â By combining rebates, finance, and VPP participation, you can often bring your upfront costs down significantly - and accelerate your path to zero power bills.
At NRG Solar, weâll guide you through the options to make your investment work harder.
When you connect your battery to a VPP like Amber SmartShift, you unlock extra savings and can claim a REPS (Retailer Energy Productivity Scheme) rebate from the SA Government.
- REPS rebates range from $780â$1,500 for most households (capped at 28kWh of battery capacity). Concession holders can get a higher rebate rate.
- Amber also provides a savings calculator so you can see the potential return on investment before you commit.
- Thereâs no long-term lock-in â you can trial Amber for a quarter and see how the algorithm optimises your battery before deciding if itâs right for you.
To make solar and battery storage even more affordable, NRG Solar has partnered with Solaris Finance to offer a market-leading 6.29% Green Loan (vaiable).
- Loan terms: 2â10 years, with no early pay out fees.
- Fees: $395 establishment (added to the loan) + $10/month account fee.
- You can finance the full system price or pay a deposit and finance the balance.
- A signed order is required to apply.
There are a number of lenders who offer green loans to finance your solar and battery needs. Green loans often have lower interest rates as an incentive for consumers to make these âgreenâ purchases. Commbank green loans are available for Commonwealth Bank customers who have an eligible Commbank home loan or investment home loan.
Payments you receive for solar power you feed into the grid is based on the Feed-in Tariff or FiT.
FiT is also known in South Australia as Voluntary Retailer Contributions. Feed-in tariffs are deemed âvoluntaryâ in SA because energy retailers here are not obliged to buy exported solar power. But the good news is that most do.
â
The current solar FiT rate in SA ranges from around 2 to 10 cents per kilowatt-hour (kWh). Compare this with the cost of buying electricity from the grid at 35 to 81 cents per kWh. You can quickly see why storing and using your own surplus solar power has big financial benefits!
In recent years, feed-in tariffs have been in decline or in some cases, have been phased out altogether by energy retailers. We consider the feed-in tariff a ânice to haveâ because we know that the big savings with solar are in selfâconsumption. This is the power you generate with your panels and use throughout the day â what you donât see on your power bill.  Â
Consumption monitoring, which is available with quality, modern solar, helps you understand how much energy youâre producing and using. The way to save more is to increase your daytime consumption while the sun is shining.  If  you are producing more power than you can use, it makes sense to consider storing it and using it at night instead of buying it back it at a much higher rate.  If you already have solar, and your power bills are still high ,it could be time review your existing system. Is it time to upgrade to a more efficient system or add battery storage?
Your NRG Solar consultant would be pleased to show you how to maximise your solar investment.
