5 Best Solar Panel Installers in Sydney to Give Your Power Bill a Break
Every time my power bill lands, I look at my sun-drenched roof a little differently. I’m seriously considering getting solar panel contractors to put it to work.
But a new home, a warehouse and a battery upgrade won’t need the same setup. I want a team that asks how I use power before telling me what to buy.
So I’ve rounded up the best solar panel installers in Sydney to help narrow the search. Here’s where I’d start looking for sensible designs, solid gear and support after installation.
How much does solar panel installation cost in Sydney?
A fully installed residential solar system in Sydney typically costs $4,500–$11,500 after rebates. The price depends on the system size and your home’s energy needs.
A 3kW–5kW system costs around $3,000–$5,500. It may suit a smaller home with low power use.
A 6.6kW system costs about $4,500–$8,000. It’s a common option for a 3–4-bedroom home.
A 10kW system costs roughly $7,500–$11,500. It may suit a larger household or one charging an EV.
A 13.2kW system costs around $9,500–$13,500. It’s an option for high energy use, including homes with three-phase power.
1. EcoSun Power
Address: 20/1 Maitland Pl, Norwest NSW 2153
Contact: 1300 669 551 | [email protected]
Hours: Monday-Friday, 9 AM – 5 PM | Saturday, 10 AM – 2 PM
I’d be suspicious of a solar quote that arrives before anyone asks what’s happening under my roof. EcoSun Power starts with your power use, roof space and shade, then talks through a system that fits.
Got an EV or battery on the horizon? They’ll factor that into the plan, so you’re thinking beyond next month’s bill! If you’ve already got panels, they can check whether your existing setup is compatible with a battery.
They work with homes, warehouses and other suitable business sites, where operating hours can change the whole solar equation.
The small hitch is that you’ll need to share details about your property and power use for a tailored quote. That adds a step when you’re comparing installers, but it gives them something useful to base the recommendation on.
Smooth Installation and Clear 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 and Flexible Solar Options
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. Isolux Solar
Address: Suite 601, Level 6, 159–175 Church St, Parramatta
Contact: 1300 552 452 | [email protected]
Hours: Monday-Friday, 9 AM – 5 PM
If I’m putting panels on my roof, I’d like to know who’s fitting them and what cover comes with the job. Isolux Solar’s systems are installed by licensed, SAA-accredited electricians, with a Parramatta office to contact about the project.
Its packages include a choice of system sizes for homes, and it handles commercial solar too.
The advertised cover separates a 25-year panel performance warranty from the panel manufacturer’s warranty, with 10-year workmanship cover available.
I’d give its $0-deposit, interest-free finance option a look if paying everything upfront would sting. I’d still check the full repayment terms and exact equipment in my quote before picking a package.
The catch is that its office is open only from 9 AM to 5 PM on weekdays. If those are your working hours too, you’ll need to find a gap to call.
Professional Solar and Battery Installation
Isolux installed our solar panels in 2023. We were extremely impressed with the communication, the professionalism of the team, and the workmanship of the installers – a benchmark for the industry overall. This week, Isolux installed a new battery system, which has been integrated with the existing solar, and it is working beautifully. Gary, the sales rep, was fantastic and kept us informed during the whole process. Abdul and his team have done an excellent job with the installation. Highly recommend Isolux.

Quick, Tidy, and Well-Communicated Service
I couldn’t be happier with my decision to go solar panel and battery with Isolux. From the initial consultation with Kunal, who was patient and answered all my questions without any pressure, to the installation team, everyone was professional and a pleasure to work with. The installation was surprisingly quick and tidy. The crew arrived on time, worked efficiently, and cleaned up completely afterwards. They were also very neat and paid attention to the details. Sam in the customer service team was a legend and provided all the key updates in a timely manner – love the service, Kunal & team!! Highly recommended!!

3. Solar Harbour
Address: 27/5 Inglewood Place Norwest
Contact: 1300 252 090 | [email protected]
Hours: Monday-Friday, 9 AM – 6 PM
If your solar wish list now includes an EV charger, Solar Harbour gives you plenty to explore. I like that its panel range offers choices for different roofs and budgets, rather than one setup for everyone.
There’s help with batteries and meter upgrades too, although meter work may cost extra.
For businesses, Solar Harbour designs commercial systems and handles grid connection applications, which could save you some paperwork.
The warranty caught my eye if I might sell my place down the track. Its 10-year installation and workmanship cover can transfer to the next owner, provided I notify Solar Harbour in writing.
My one pause is the payment schedule: a 10% deposit is due within two days of signing. That’s a quick turnaround, so I’d read the quote and cooling-off terms before committing.
Stress-Free Solar and Battery Installation
We recently had our solar panels and battery installed by Solar Harbour, and we couldn’t be happier with the experience. The entire team was highly experienced, professional, and friendly from start to finish. The sales team made the whole process simple and stress-free, explaining everything clearly and helping us choose the best solution for our home. The installation was completed efficiently and to a high standard. We are very happy with the service and would definitely recommend Solar Harbour to anyone looking for a reliable and professional solar company. Thank you for making the whole experience so easy!

4. Natural Solar
Address: 17/390 Eastern Valley Way, Roseville
Contact: 1300 060 928 | [email protected]
Hours: Monday-Friday, 8 AM – 5:30 PM
If I were building a new home, I’d want to plan the solar setup before the roof goes on. Natural Solar’s work with housing developments makes it a team I’d speak to early about panels and battery storage.
I like that its range covers panels, batteries and EV chargers, so you can think beyond today’s power bill.
There are several panel brands to compare too, giving you options for your roof and budget.
Its commercial experience goes beyond a glossy brochure. Natural Solar installed a ten-battery system for a Domino’s store in Sydney’s west, showing it can tackle bigger energy needs.
The catch is its Monday-to-Friday office hours. If your workday runs on the same timetable, you’ll need to squeeze in an enquiry before knock-off.
Successful Tesla Powerwall Installation
I recently had a Tesla Powerwall installed alongside my existing solar panel system, and I couldn’t be happier with the entire experience. From the initial consultation to the final setup, the installation team. Thanks again.

Quality Installation and Strong After-Sales Support
Natural Solar provided quality products at competitive prices to install our solar panels and inverter. There was minimal delay between finalising design and commencing installation. The team on site were efficient and knowledgeable and kept us advised of progress and any changes required to the original design (minor). In addition, the after-sales technical help in ensuring that we can monitor the system activity has been exceptional. Have no trouble recommending this firm for solar panel installation at your home.

5. Sydney Wide Solar
Areas served: Greater Sydney & surrounding regions
Contact: 1300 309 980 | [email protected]
Hours: Monday-Friday, 8 AM – 6 PM | Saturday, 9 AM – 4 PM
If I’m putting solar on the roof, I want more than a cheery goodbye when the installers pack up. Sydney Wide Solar’s 15-year workmanship warranty covers its installation work, including roof penetrations and weatherproofing.
I like that it offers 24/7 system monitoring and technical support for when your power bill starts behaving oddly.
Its solar, battery and EV charger services could make a bigger home upgrade feel less like herding tradies.
Businesses get more than a panel count too. Sydney Wide Solar includes financial modelling, projected returns and grid connection work in its commercial solar process, helping you weigh up a sizeable investment.
However, the payment schedule is the part I’d check before signing. You pay 10% at signing and another 40% when the equipment arrives, with the remaining 50% due after completion and commissioning.
Fast Installation and Great Value
Emil, Luke and the team went above and beyond to make our solar installation experience a great one. They were the best value for money of the three quotes we got, and also the best to deal with because they’re really genuinely lovely people, but also because they install the system themselves. Once we agreed to the quote, it was installed in under a week. I’m really confident going forward that if I have any issues, they’ll be there to help.
