How does a solar battery work?

A solar battery is to be used in conjunction with your solar panels / solar system.


When you don’t have a battery
, you are limited to consuming solar power during daylight hours when the sun is shining. This can limit the return on your solar investment.


Considering most homes don’t use all their electricity during the day the solar system will export any excess electricity to the grid and the electricity retailer will provide a credit for each kilowatt hour exported.


When you do have a solar battery
, you can store excess solar power and utilise this when the sun goes down.


When a solar and a battery system is combined
, in most cases, the solar will provide the home with electricity and the excess that isn’t used by the home will charge up the battery.


Once the battery is fully charged any additional electricity will be sent to the grid and you will usually earn a small credit for doing so.


Once the home is using more electricity than what is being generated by the solar, which is usually at night, the battery will discharge the stored power into the home.

What are the benefits of installing a solar battery?

The benefits of a solar battery are vast. In no particular order, this includes:


1. You will obtain autonomy and rely less on power companies

Installing a solar battery at your home will increase your home’s autonomy and you will rely less on electricity providers. You will be able to generate, store and consume all your own electricity making you much less reliant on the grid.


2. You will save money

Having a battery can save you money. While the returns on solar are much stronger, batteries are becoming much more lucrative with state rebates. A solar battery will enable you to use your stored electricity when you need it.

If you are on a Time of Use Tariff the PEAK charge is when a lot of homes use their electricity. This is commonly between 2pm-8pm Monday to Friday. The cost of electricity during this PEAK period can be around 50c/kW depending on which state you are in. Using a battery in PEAK periods will significantly reduce your overall cost of electricity.


3. You will be protected from blackouts (and brownouts)

Good solar batteries will come with blackout protection. This functionality will allow the home to use stored battery power when the grid goes down.

You will be smiling with the lights on (and cold milk in the fridge!) while your neighbours are sitting in the dark.

One of our customers recently found out their entire neighbourhood had been without power for nearly 12 hours, unbeknownst to them as their battery kicked in.

Black out protection is also great for those who have certain appliances which need electricity, such as pumps on a toilet for a rural property.


4. You will be less impacted by the rising cost of living

A solar battery combined with a solar system will allow you to secure your home against the aggressive price increases of electricity from the grid. Electricity prices continue to rise, year in and year out, making the investment in a battery a safe way to protect yourself against these price rises.


5. You will be able to be in full control of your energy

Certain electricity providers allow you to sell your stored energy back to the grid when demand is needed. This can be quite profitable due to the supply vs demand economics in play when the grid is unable to meet consumer demand.

With a solar battery, you get full control. You can manage the solar battery via your own mobile app and participate in virtual power plants (or VPP for short).

A VPP is network of decentralised generation and storage units, which are solar and battery systems across the country connected in one big virtual battery. When the price of electricity on the wholesale market goes UP, the batteries will discharge together and earn the Virtual Power Plant operator revenue, which can be shared with the owner of the battery.

Each Virtual Power Plant is different, but the concepts are very much the same. Having a battery combined with your solar system will allow you to take part in these new programs.

Don't just take our word for it.

Green.com.au has helped thousands of Aussies switch to solar and battery power. Here’s what some of our happy customers have to say.

I have a solar system with another company. Which is working well. 7.48 Kw, 17 panels, works well with the batteries. May 1st I bought a 10.1 Kwh battery from green.com.au. All the staff were great, friendly, polite and they know what they are talking about. All paperwork was done by Green - connection to the grid. I didn't have to lift a finger. The guys know exactly what is required. Nothing is a issue. I'm so happy to have dealt with them. Before I knew it the battery was in my driveway. Simon and company did a great job. I've had no power bills for 9 months - that's zero. Great feeling. Anyone who is interested in a system, get in touch with green.com.au, You will not look back. Love ya work guys.

I have been very happy with the service and installation of my 26kWh Alpha ESS battery from green.com.au. This is to go with existing Enphase panels that I have had for over 5 years. The quoting process was quite straight forward. I was given options of different batteries and different capacities. The installation by Marcus and his team was excellent. Their workmanship and approach was very professional. They did a great job of explaining the system, how it works and setting up the app so I can monitor progress and my savings.

Green have been extremely efficient, intelligent and supportive with the quoting and installation of my Sungrow solar batteries. Efficient with the quoting , Government grants and delivery/ installation. Intelligent with the placement, wiring and structuring of the equipment and supportive during the complete process.

Right from the very first phone call with Brad to the final install with Shakeb it all went effortlessly. Green kept me informed all the time with regard to install time and whether there were any changes. After initially giving me an installation date I was quite surprised when they called me and offered me an earlier date as I knew how busy they were. Showed up on time the day of installation and the guys worked tirelessly the whole time without stopping till the job was done. Treated myself and my home with great respect regularly letting me know how it was all going. Very impressed. When they came for the final inspection, they answered any questions I had and showed me how it all worked. I would definitely recommend Green to anybody. Thanks for the great service.

Jono, Dave and the Green Team or should I say the dream team did an amazing job. From quotation to the job finishing it took very little time with the installation only taking 1 and a half days. The technician Alex was very professional, clean and respectful and looked after the property. He installed the panels beautifully and even spent time to set up the app with me so that I can track how much solar energy I’m using. If you need solar installed at your home, Green is highly recommended!!
Tin Jung Shea
I recently had a solar panel and battery system installed at my home in Dubbo through Green.com.au, and I couldn’t be happier with the whole experience. From the very beginning, the team was professional, knowledgeable, and easy to deal with. They helped me choose the right system for my household’s needs without any pressure, and explained everything clearly. The pricing was competitive, and I appreciated how transparent they were throughout the process. Installation went smoothly—the crew arrived on time, were polite and tidy, and had everything up and running in no time. Living in Dubbo, having a reliable solar and battery setup makes a real difference, especially during the hotter months. Since the system went live, I’ve already seen a big drop in my power bills and love knowing I'm more energy-independent. If you’re thinking about getting solar in regional NSW, I’d definitely recommend Green.com.au. Great service, great system, and a great investment

Want to extend my sincere thanks to Ryan Towle and his incredible team for their outstanding support in helping me get my solar panel system and loan approval finalised so quickly. From the very beginning, they were professional, responsive, and highly organised. Ryan kept me informed at every stage and made the entire process smooth and stress-free. The turnaround time was impressive, and the level of care and communication throughout was exceptional. Thank you again for doing such an amazing job!
Trung Nguyen
Recently had the privilege of working alongside Jono and his incredible team at Green.com.au. They helped install solar on my parents place and we are thrilled with the service - from the quote all the way to the installation, the process was seamless and easy. Would 10/10 recommend to anyone considering getting Solar. Thanks again Jono and team.
Lachlan
My dealings with Green have been extremely positive. I was a bit lost from all the information online and Green took the time to explain and work out what’s best for me. It’s nice to deal with a company that actually cares. Thank you Green, highly recommended!
Sophie C
I recently had solar panels installed by Green.com.au and I couldn’t be more impressed with their service from start to finish. The entire team was professional, knowledgeable, and transparent throughout the process. They took the time to explain all my options clearly, answered every question I had, and never made me feel pressured. The installation itself was smooth and on schedule, and the crew was respectful of my property, leaving everything clean and tidy once the job was done. What really stood out was their post-installation support. They walked me through how to monitor my system, helped with all the paperwork for rebates and incentives, and checked in afterward to make sure everything was working properly. I’ve already started seeing savings on my energy bill, and I feel great knowing I’ve made a more sustainable choice. I highly recommend Green.Com.AU to anyone considering solar. Green truly made the transition easy and stress-free.

Every step in the process has been handled professionally and smoothly - from Quoting, Sales contract , scheduling to installation. 2 glitches occurred outside Green control - NSW Government dropped their Grant and Battery supply was slowed due to high demand. Both issues were handled very well and I was kept informed on progress and rescheduling. Since installation follow up questions have been fully answered, enabling a good understanding of the new system. I strongly recommend Green.
Bob
Excellent and responsive communications at all stages. Very helpful staff and the result was a battery system at a good price that is working exceptionally well.
Kerry Jorgensen
Would recommend green.com.au after a great experience. We toyed for years as to whether to go solar panels and eventually did. Abby Carbines at Green.com.au was great. Patient and full of all the information we needed to finally get us across the line. The customer service was great and install process was awesome. The panels also visually look so much nicer than our neighbours if roof aesthetics matter to you. Our bills with Red Energy have definitely been reduced by half since installing solar panels, but we're still working out how best to maximise it all.
Byron W
Australian owned company using local trades people. Great communication through the whole process. Great product.
David Scott
I needed some help with the app on my phone and they were very friendly and helpful. Over all I was very happy. The cost was less than I had expected and everything was delivered and done when they said it would be, except the inspection, which was done much earlier, which meant it was up and running the next day. The installers were very friendly and helpful. Over all I am totally happy with the results.

First class communication, easy to deal with, good price, great installers, all in all a great experience. And a great feeling when I see how much lower our electricity bills are!
