5 Best Solar Panel Installers in Sydney to Put Your Roof to Work
I’ve bluntly asked some of Sydney’s top electricians how to cut my power bills. Their answer keeps pointing me towards the sunny bit of my roof.
Of course, a few panels won’t help much if the system’s a poor fit. I’d want an installer who checks my usage and roof before pitching a package.
So I’ve rounded up the best solar panel installers in Sydney. These teams can help you work out what belongs on your roof and what might actually save you money.
How much does solar panel installation cost in Sydney?
A fully installed residential solar system in Sydney typically costs $4,500–$11,500 after the federal STC rebate. That works out to roughly $1,000 per kilowatt.
A 3kW–5kW system costs around $3,000–$5,500. The common 6.6kW system costs $4,500–$8,000. Budget 6.6kW systems cost $4,000–$5,000, while premium options cost $7,500 or more.
A 10kW system costs about $7,500–$11,500. A larger 13.2kW system costs $9,500–$13,500.
A double-storey home or terracotta tile roof can add $300–$600. A switchboard upgrade adds around $800–$2,000. A 10kWh–13.5kWh battery adds roughly $9,000–$11,000.
1. EcoSun Power
Address: 20/1 Maitland Pl, Norwest
Contact: 1300 669 551 | [email protected]
Hours: Monday-Friday, 9 AM – 5 PM | Saturday, 10 AM – 2 PM
I’m all for putting Sydney sunshine to work, but I wouldn’t want a solar system picked from a shelf. EcoSun Power looks at your electricity use, roof space and shading before discussing what size might suit your home.
I like that they’ll factor in future plans, whether you’re eyeing a battery or expecting an EV in the driveway. You can start with a recent power bill, so you don’t need to know your kilowatts from your kettle just yet.
They handle residential solar, battery storage and commercial installations across Sydney. That range could be handy if you’re upgrading an existing setup or weighing up a larger project.
The catch is that you’ll need to share details about your property and power use before getting a tailored quote.
That’s sensible for system design, though it adds a step when you’re comparing installers in a hurry.
Smooth Installation and Helpful Guidance
We recently had our solar system installed by Ecosun Power, and the experience was excellent from start to finish. The team was kind, professional, and very helpful throughout the entire process. The installation was completed perfectly, and they took the time to clearly explain how the system works and how to get the most out of it.

Helpful Advice Without the Hard Sell
Sam and team did a wonderful job. Sam was so helpful and provided me with the best solution needed. He was constantly in touch from the day I contacted him, guided me through the finance process and through to installation. He knows exactly what is needed and doesn’t force you into buying something; instead, he gives you various options to choose from. I would definitely recommend him to anyone who wants a solar/ battery.

2. Solar Galaxy
Address: Level 57, MLC Centre, 19-29 Martin Place
Contact: 1300 339 596 | [email protected]
Hours: Monday-Friday, 9 AM – 7 PM | Saturday, 9 AM – 3:30 PM
I’d be wary of anyone choosing my solar panels before asking when I actually use power. Solar Galaxy starts with household energy needs and recommends a system with the years ahead in mind.
They work with different panel and inverter brands, which gives you more to weigh up than a single manufacturer’s range. I like having options when the gear will be sitting on my roof for years.
They handle residential solar, batteries and commercial projects, so there’s room to plan beyond a basic rooftop setup.
Their residential workmanship warranty can run for up to 10 years, provided you meet its inspection and maintenance conditions. The extended residential workmanship warranty requires follow-up care, though, so check those conditions before signing.
Do note that installations are carried out by contractors, which may not suit you if you’d prefer an in-house crew.
Professional Installation and Clear Explanations
Excellent job, friendly staff members, especially Adam. We recently had our solar system installed and are very happy with the entire experience. The team was professional, punctual, and completed the installation to a high standard. Specifically, Adam explained everything clearly and made the process smooth from start to finish. The system is working great. Highly recommend their service to anyone considering solar installation. 👍👍

Professional, knowledgeable, and genuinely customer-focused exactly the kind of service you want for such an important investment.

3. Opera Solar Energy
Address: 6 Kanadah Avenue, Baulkham Hills
Contact: 1300271430 | [email protected]
Hours: Monday-Friday, 9 AM – 6 PM | Saturday, 9 AM – 2 PM
I’m happy to leave solar schematics to the people who can read them without squinting. Opera Solar Energy offers engineering and PV design advice to help match a system to your home’s energy needs.
You can compare Gold, Diamond and Platinum packages, then adjust the equipment to suit your plans.
I like that they offer one point of contact through the project, especially when panels, batteries and installers all need coordinating.
Their services continue after installation, with technical support and solar maintenance available. That’s handy if you’d rather call the company that planned your system when something needs attention later.
However, there’s a catch if you already have an electrician you trust for repairs. You’ll need Opera Solar’s written consent before they work on the system to keep its workmanship warranty intact.
Patient Planning and Strong After-Sales Support
After contact with several companies, Opera Solar Energy showed great attitude and professionalism. Andy was always happy to answer my many queries and was available even after hours. He was patient even when I asked for quotes for different systems during the planning process. Allan and Brian were also great during the installation process. There was a small hiccup, but Andy helped us to resolve it, so I can safely say their after-sales support is fantastic!

We recently had solar panels and a battery installed by Opera Solar. Andy took the time to explain everything and was always quick to respond when I had questions. Nick and the installation team did a great job on the day. Everything went smoothly and was finished on time. The system has been running well so far, and we’re really happy with it. Would highly recommend them.

4. Green Reliance
Address: Suite 15/60 Station St E, Parramatta
Contact: 1300 650 863 | [email protected]
Hours: Monday-Friday, 9 AM – 5 PM
A sunny roof’s one thing; knowing what to put on it is another. Green Reliance has worked in solar since 2010 and says it’s installed more than 40,000 panels, so it’s seen plenty of rooftops.
I like that they consider whether solar suits a property before recommending a system. They match local installers to the job’s complexity and can help with pre-installation approvals, which takes some of the paperwork off your plate.
For households watching the upfront cost, they advertise payment plans lasting up to 10 years, including a zero-upfront option. I’d check the interest rate and total repayments before choosing one, though, since the monthly figure never tells the whole story.
The scheduling snag is that the office closes on weekends. If Saturday is your only chance to talk through a quote, you’ll need to fit that conversation into a weekday instead.
Thorough Explanations and Friendly Service
We recently purchased solar panels from Green Reliance Solar. I have been referred by other family members who have had solar installed from this company. Thanks to Loveen Bansal for explaining and making the whole process seamless. I have been dealing with him, and he went out of his way to explain everything. Anthony and Maxi, the installers, were very professional and friendly. They explained to me in detail what they would do and kept me updated throughout the whole installation process. A big thanks to the whole team for amazing service and knowledge. Sonia

5. Solar World Power
Address: Level 8, 25 Restwell St, Bankstown
Contact: 1300 131989 | [email protected]
Hours: Monday-Friday, 9 AM – 5 PM
I’m keen on solar savings, but I still want to know what’s going on my roof. Solar World Power offers residential systems from 5kW to 20kW and has panel and inverter options from brands such as Trina and Fronius.
Its 6.6kW package starts at $4,450, which gives me a useful figure to take into a quote discussion. I’d still check the exact hardware and final installation price before deciding whether it suits my budget.
The company offers 30kW systems for larger projects and has an in-house installation team.
I like that it provides after-sales support and system checks, so there’s someone to call once the panels are up.
Warranty claims do require some homework, including your sales paperwork and details of the fault. Some claims need photos or video too, and an unnecessary callout can cost from $150.
Smooth and Stress-Free Installation
We had a great experience with Solar World. The team was professional, knowledgeable and very helpful throughout the whole process. They explained everything clearly, answered all our questions and made the installation process smooth and stress-free. Very happy with the service and quality of work. Highly recommended!
