Why solar works differently here

Solar power built for South Australia

South Australia has more rooftop solar per household than almost anywhere in the world. That is great for the grid, but it changes what a good system looks like. Midday exports earn very little, so a system sized to export as much as possible rarely pays back as fast as one sized to your own usage.

We're not a one-size-fits-all installer. As SAA-accredited designers and installers, we look at your roof, your power bills and your SA Power Networks connection options, then build a system that keeps more of your solar working for you, with or without a battery.

Where we install

Solar installation across South Australia

We service the corridor running north from Adelaide into the Barossa. Choose your area for local details and pricing.

Northern Adelaide

Gawler

One of SA's fastest-growing towns, with new estates in Gawler East and Evanston built for solar from day one. Older homes in town are prime candidates for a battery added to existing panels.

Also covering: Evanston, Hewett, Willaston, Gawler South

Solar installation in Gawler → Adelaide Plains

Two Wells

Larger rural blocks, sheds and pumps on the Adelaide Plains. Some rural properties here sit on single-wire (SWER) lines, which changes how much you can export.

Also covering: Lewiston, Dublin, Mallala

Solar installation in Two Wells → Northern Adelaide Plains

Virginia

The heart of the Northern Adelaide Plains growing district. Glasshouses, cool rooms and irrigation make daytime solar a natural fit for growers.

Also covering: Angle Vale, Waterloo Corner, Buckland Park

Solar installation in Virginia → Southern Barossa

Williamstown

A hills town at the southern edge of the Barossa, where a cooler climate means longer winter heating loads for a well-sized system to cover.

Also covering: Lyndoch, Mount Crawford, Kersbrook

Solar installation in Williamstown → Barossa

Barossa Valley

Wineries, cellar doors and processing sheds with heavy daytime refrigeration. Those daytime loads line up closely with solar output.

Also covering: Tanunda, Nuriootpa, Angaston

What we do

Solar services for South Australian homes and businesses

Every system is designed around your roof, your bills and your network connection.

Residential Solar Panels

Panels and inverters sized to your roof and your actual usage, not the biggest system that fits. With SA's low feed-in rates, a right-sized system pays back faster and keeps more of your solar in your home.

Explore residential solar →

Solar Battery Storage

Store cheap midday solar and use it through the evening peak, when grid power costs the most. We fit flexible-export-ready inverters that meet SA requirements, now or as a future upgrade.

Explore battery storage →

Commercial Solar

Rooftop systems for sheds, warehouses, wineries and growers. Our delivered commercial jobs run from 66 kW to 100 kW, and eligible business systems up to 1 MW can now claim the upfront STC discount.

Know before you buy

How SA's network shapes your system

Three things every South Australian solar quote should account for.

Flexible Exports

SA Power Networks offers Flexible Exports to every new or upgrading solar customer. Your export limit moves with network conditions, so your inverter must be compatible and online.

Rural SWER lines

On single-wire earth return lines, common on rural blocks, the lower export limit is 0 kW rather than 1.5 kW. We confirm your site's options before quoting.

Low feed-in rates

Some SA plans pay little or nothing for midday exports. Designing for self-consumption, and adding a battery where it stacks up, is usually the faster payback.

Frequently Asked Questions

Do you install solar outside metropolitan Adelaide?

Yes. We install across Gawler, Two Wells, Virginia, Williamstown and the Barossa Valley, plus the surrounding towns, for both homes and businesses.

Can I still export solar in South Australia?

Yes, within the limits SA Power Networks sets for your address. Flexible Exports lets compatible, internet-connected systems export more when the network has capacity. On rural single-wire (SWER) lines the lower limit is 0 kW, so we check your site before quoting.

Is a solar battery worth it in South Australia?

Often, because feed-in rates are low and evening grid power is expensive. A battery stores your midday solar for the evening peak. We model your actual usage before recommending one.

Do you install commercial solar systems over 100 kW?

Yes. From 1 October 2026, eligible business systems above 100 kW and up to 1 MW can claim the upfront STC discount, with a fixed five-year deeming period.

Are you accredited?

Yes. Our designers and installers are SAA-accredited, so your system meets the standards required for rebate eligibility and safe operation.

Kirrana Bell

We recently had a GoodWe battery system installed by Energy Systems Australia, and we’re really happy with the result. There were a few delays because of high product demand and changes to the solar installation regulations at the time, but the team did their best to work around this and even came to our home on the weekend to complete the installation. A big thank you to James, who led the installation team. He and the team were hardworking, professional and genuinely dedicated to getting the job done properly. Chris and Peter were also always easy to reach whenever I had questions. They took the time to explain everything, offered helpful advice and really put my mind at ease throughout the whole process. I also loved that they arranged for our old solar panels to be taken away—it saved us a lot of hassle. Thank you to the whole team. We truly appreciate all your hard work and would happily recommend Energy Systems Australia!

John Riley

I was recommended by a family member to energy systems Australia, from the first time I spoke to them i new I was talking to someone that new there stuff. He spent time explaining every question I had ,and that put me at ease. Come install day and the two young lads where so respectful and just genuine blokes, they where so clean in ever thing they did answered all my questions on the day.i would highly recommend this company to anyone looking for a home battery and solar.

Leah & Tim Clifton

From the first engagement with the sales staff they guided us through the process and understanding how to achieve the best return without compromising the quality of the system components. I would definitely be recommending Ian and Kyle to my friends and family.

Hiedie S

Chris and Meyer have been fantastic through the whole process. Prices were very competitive. Communication was excellent. Would highly recommend.

Paul from Ripley

I recently had a home battery system installed by Energy Systems Australia and couldn’t be happier with the experience. From my first contact through to installation, the entire process was smooth, professional, and well organised. The installation was completed on time and exactly as quoted, with no surprises. I’d especially like to thank Zac, who was outstanding throughout. He was never pushy, always available to answer questions, and took the time to help me understand everything in a way that made sense. As an aged pensioner making a significant, once-in-a-lifetime purchase, that level of patience and care made a big difference. The installation team were also excellent — polite, professional, and clearly took pride in their work. They also honoured everything they promised, including payment terms, which gave me a lot of confidence. I’d have no hesitation recommending Energy Systems Australia and will definitely be going back to them when I look at expanding my solar system in the future.

charlie cachia

Great experience dealing with the staff from Energy Systems Australia from start to finish, when I had questions they were always happy to answer them and always returned my phone calls and emails, the system has been running for a month now and works perfectly, I would highly recommend Energy Systems Australia to anyone that is looking for Panels and Batteries, thanks to Chris and all the staff

Tony Iommazzo

Great work, friendly and professional..

ben barnes

I would strongly recommend that anyone considering this company proceeds with caution and ensures all compliance requirements are confirmed upfront, as the gap between sales promises and delivery has been significant in my experience.

Tom Ely

Did a very neat and efficient instal. There was few delays getting the installer organised.
