Fantastic team

I recently had a 10 kW Sigenergy inverter with 18.04 kW of Aiko panels and a 32 kWh battery installed by Koala Solar, and I couldn’t be happier with the experience.

From the very beginning, Sean was my main contact and he has been excellent. I sent him multiple emails with lots of detailed questions, and he always got back to me with accurate answers. If he wasn’t sure, he would follow up with the right people and come back with the correct information. I wouldn’t say every answer was instant — sometimes I had to follow up — but given how busy the rebate period has been, that was completely understandable. Compared to many other top-tier installers in WA who never even responded to my enquiries, Koala Solar’s communication was outstanding.

Other staff members including Bri and Kristy were also very helpful and professional. My solar journey had a stop-start moment when the WA government backflipped on their election promise about rebates. I initially booked and even had an install date, but I cancelled once things became uncertain. I expected resistance or pushback, but Koala Solar made it very easy. They simply said “when you’re ready, give us a call back” — no pressure, no hassle. Once everything was clarified, I re-engaged with them and was able to pick up right where I left off.

The installation team led by Callum arrived promptly on the day of install. They worked efficiently, answered all my questions, set up the app, and explained everything clearly. They left the site neat and tidy, which I really appreciated.

Overall, I am extremely happy with both the system performance and Koala Solar’s professionalism. At no point did I have to pay a deposit, and the entire process was smooth and transparent. I would strongly recommend Koala Solar to anyone in Perth who wants a high-quality solar and battery installation.

Great bunch of guys

Great company to deal with, clear from the beginning and great after install support. 100% recommend.
Battery rating: 5/5

Really happy with Koala Solar. Would recommend to family and friends.

How was the sales/quoting process? - Really simple. A call back and a great 15 minute conversation that brought me up to speed on all of the conditions and rebates and eligibility requirements etc. After getting some dubious quotes from some pop-up companies, look at their "suspicious" 5 star ratings, we did our research and looked for a reputable company that had been established a significant time and we happened to find Koala Solar.
After rebates, $10,000 all up for 9.8 kw panels across two roof slopes, 16 kwh battery and 5 kw inverted all Sigen.

How did the installation go? Polite? Tidy? Punctual?
Great. I initially had Sep 19th booked in for install, received a phonecall yesterday afternoon (1st Sep) saying they had a cancellation and wanted to know if I wanted it installed tomorrow morning!! (2nd Sep). They arrived at 6:30 and were done by 10:30. Really impressed with the blokes. Stu is the owner of the company and was present with 3 other tradies; one an apprentice, love that they are training up more guys!!! All the guys were polite and friendly and professional. Everything was cleaned up and I was left to play with the mySigen app and see all the power I was generating.


How was the customer service? e.g. did they help organise the grid connection after the install, or show you how to use the charger? Yep. Stu and Jarrod stayed back and got me to download the app and log in. They ran me through a few things; battery, charging to battery, drawing from battery, etc etc. The app is pretty good.

Five stars in all areas.

We have just had a SigEnergy battery system installed and have been engaging with various members of the team for a few months now and they have all been so friendly, knowledgeable and helpful. I've spoken to the office staff, the sales staff and the installers.

The product is also top notch, nothing you can fault with this business.

Best Solar Company!

Right from the start Koala Solar were very attentive to my enquiry and not pushy for a deal! Everyone is so friendly and the service is amazing, very knowledgeable. Always keeping in touch at all the significant steps and answering all my questions. Very competitive pricing for very good quality products. We shopped around a lot and the products were the highest tier for the lowest price. I would highly recommend Koala Solar to anyone!

Thankyou for installing our solar.

A great decision to go with koala

Dealing with Koala Solar was aver simple process. The various solar options and costs involved were simply explained as were the potential savings for each option. The installation team were very friendly and efficient. All rubbish was removed and the premise was left in a clean state. After installation, the lead hand explained how the system operation and help me install the Sigen App on my phone. Excellent job guys.

Professional team and well priced system

This is the second time we used Koala Solar to install a system for us. The original 6.6Kw system with %Kw Fronius inverter still worked flawlessly but it was over 6 years old and we wanted to upgrade to a larger system with batteries so Koala Solar was the obvious choice for us. The quote received from them for a 18Kw solar, 48Kw battery and gateway box was better then expected with the other installer referred by Finn from Solar Quotes giving us a quote that was about $10k higher for a smaller 14Kw solar,40Kw battery and no gateway system. The people from Koala came at 7am as promised and the 5 guys removed the old system, did a neat installation of the new system and left the place as clean as they found it taking away all the rubbish, old panels , rails and bolts. Including commissioning of system, showing us the features of the system and how to operate the system it was all done in under 8 hours even with a couple of quick showers during the morning.

Great Service and Friendly Team - Highly Recommend

I’ve used Koala Solar on two separate occasions and have been impressed both times, firstly in 2020 for a 6.6Kw system, Fronius Inverter and Jinko panels) and now for Frankin 13.6Kw battery.
The team is professional, friendly, and easy to get in touch with, making the whole process completely hassle-free from start to finish.
Their communication is clear, their work is reliable, they left the workspace clean and tidy, and everything is handled with great care. I wouldn’t hesitate to use them again and highly recommend their services to anyone looking for a smooth, stress-free experience with genuinely friendly staff."

Second Time Return Customer

The office administration team is outstanding—always quick to respond to my emails. The installation crew arrived punctually, discussed the ideal placement for the system with me, and carried out the installation smoothly. They left the area spotless and thoroughly explained how to set up the app and use the system. A fantastic local business that’s a pleasure to deal with—highly recommended!

Highly recommended battery installer

With the federal battery rebate kicking in, I came to Solarquotes to find a suitable battery installer.
Koala Solar had really high ratings and were also recommended by the actual battery company (FranklinWH) as one of their preferred installers. I chose FranklinWH as I already had an existing solar system and inverter that I didn't want to have to change or 'upgrade', and Koala Solar didn't try to upsell me anything like that either.
They provided a very detailed and competitive quote, and were also very clear in all communications, especially with the WA Govt messing around with their own rebates/back tracking on the amounts and what systems were applicable.
After agreeing to go ahead with Koala Solar, they found a slot for me very quickly.

Cory showed up right on time to install the system. He and his colleague were clean and efficient and got everything hooked up and working in just a few short hours. He took the time to explain the app and how everything worked together.

Would highly recommend them for any of your installation needs!

Impressive job from start to finish

Cannot recommend Koala Solar highly enough having been impressed with them through all parts of the process from initial contact and sales process, to the quote and system offered all the way to the actual installation. The installation was carried out on time with the team taking time to explain all parts of the system, and ensuring the site was left in perfect order.

Batteries to compliment our 10kW rooftop system

Koala Solar installed our rooftop solar system with Fronius inverter in 2023. In July 2025 we got them to install a 13.8kWhr BYD battery storage under the recently-introduced WA rebate system. Their quote was competitive and they kept us informed of progress with the WA and Federal Government rebates. The crew arrived on site on time, and the installation, set-up and testing was completed quickly and professionally. We are quite happy to recommend Koala Solar for their professional advice, customer service and workmanship.

Second time around

Second time we have used koala solar, with a second battery installed today and previously a battery and 15 kw of panels. Great service and installed quickly neatly and efficiently. More than happy with the install and the customer service from the team in the office. Would happily use again.

Great all-round service

We'd highly recommend Koala Solar. Both the sales and installation teams were professional, knowledgeable and honest. They really know their stuff, and are friendly and punctual. The team were extremely helpful, and provided a detailed explanation of our new battery.

5 Stars – Highly Recommend!

Had a fantastic experience with this solar power company! From start to finish, the team was punctual, professional, and incredibly efficient. They installed my 6.6kW system in just a few hours, and everything went off without a hitch.

The inverter was installed in my very cluttered garage, but the team not only managed the job with no complaints—they actually left the area cleaner than it was before they arrived! They cleaned up after themselves thoroughly and took all their rubbish with them. If it weren't for the shiny new panels on my roof, you wouldn't even know they'd been here.

Now I'm enjoying free power and couldn't be happier. Thanks so much, guys! Great work all around.

Fantastic installer

The quoting process was fantastic. Sean took the time to explain the options and quoted a system that would best suit our requirements.
Booking the installation was seamless and I was provided reminders leading up to the scheduled installation day.
The team that undertook the system installation were awesome. Their workmanship is excellent and they were very neat and tidy.
Overall I am extremely happy with Koala Solar.

Worth Waiting For

Worked hard on a rainy day to get the job done. Put up with my annoying questions and gave good handover advice. This was a word of mouth recommendation and I would also recommend using them. Stuart and team were very professional.

Great install experience!

Very happy with the service provided by Koala solar. From the detailed quote and competitive price prepared by Adam to the regular updates and bookings details provided by Bri. During the installation the Koala team were very professional, courteous and efficient. The quality of workmanship was excellent plus they were very tidy onsite. After the install they showed me how to use the Fronius inverter app and gave me tips on electricity usage. So happy with the overall experience and have no hesitation in recommending Koala Solar to my friends and family.

Extremely professional fantastic service

We had koala solar out to discuss putting solar onto our house.
Very happy with their knowledge and professionalism, they were just fantastic.
They gave us a quote, and 2 weeks later we had it fitted.
Highly recommend these guys to anyone.
Thank you guys

Solid performance. Good clean installation.

Did exactly what they said they would do without fuss. Installers turned up on time and did what they said they would do quickly and efficiently without significant problems. Went to offer them coffee at smoko but they were almost finished.
Cannot comment on value for money or quality of system yet but seem to perform to specifications.
Lost a star on customer service because the Feronius app is very unstable. I keep having to reset it and the videos I was referred to did not explain resetting adequately. I had to improvise and rest every few days. Not Koala's fault but the system is the one Koala supply.
Koala's customer Service themselves were very good and very responsive. Bri, their front of office and co-ordinator is excellent and easy to talk to. They didn't make the videos but they do supply the inverter.

Great team & install again

Once again, I've used Koala for another solar install (13.8kw system), and it was a pleasure to deal with Corey and the hard working team.
They were very responsive from quote stage to completion, and completed the 3rd floor roof install efficiently, neatly and without any issues.
Definitely worth getting Koala Solar to look at your next install!

Fantastic!

Koala solar was easy to deal with, from the quote to the end install. They were not pushy in making you sign and answered all my questions.
My father recommended Koala solar and I can see why. Great service, friendly and value for money.

Competitive Pricing, and great after install support

Adam was really up front and informative. He answered all my questions, and tailored a quote that fit my requirements. The price was far better than some other reputable competitors for the exact same system. No upfront deposit requirement also felt safe.

Installation went flawlessly, The installer was freindly and disruption was kept to a minimum, the whole job took around 4.5-5 hours

After install support also was top notch. I emailed the company a couple of hours after install as I wanted to hook my system up to home assistant server, and they replied with the information i required within 20 mins.

Overall I am very happy with the install and the level of customer support. I am now looking to get a battery install and I will most definitely be going back to these guys.

Excellent customer service and workmanship!

The quote process was super quick and easy. They didnt try and sell me the most expensive package available and asked where i was comfortable price wise and we went from there. They managed to fit me in a lot earlier than we had scheduled which was perfect for me.
On instal day they showed up exactly when they said they would and both installers were great to deal with, they got stuck in straight away and told me what to expect throughout the day.
The tidied everything up when they left and actually left the garage cleaner than before they came. They also did a great job covering up a hole I had in the brickwork from an old air con system which I was really happy with!
Before they left they set me up on the Fronius app and made sure it worked so i could track usage.
Would recommend Koala every time!

Yay. Free power

The installers were on time, polite and able to answer all my questions. They explained the system and the app and waited until I was comfortable with it all. The installation went well and all looks good. Bring on the free power.

Fantastic service and communication.

From the first phone call, everyone we interacted with was attentive and respectful. The onsite visit allowed for us to ask questions, clarify our needs and determine the best configuration for what we wanted to achieve. There was no pressure during the process. The electronic quote system was clear and easy to use. The installers were punctual, organised, professional and polite. They communicated well and ensured we understood how the system operated and the app worked before they left. The installation was not invasive in any way. They were tidy and cleaned up after themselves.

6.6KW Solar System

Koala Solar came recommended to me by a friend and my experience with them has been flawless in every aspect from the initial advice on the most appropriate system for my home to the installation and advice on operation/monitoring of the system.

Koala have taken all the hassle out of the solar installation for me and I'm more than happy with the quality of my new system and quality of the installation. The installation was completed within a few hours and the team engaged with me throughout and answered any questions I had.

I will not hesitate to engage Koala again for any upgrade to my system in future.

Reliable and Good Customer Service

We were put in touch with Koala Solar through the recommendation of SolarQuotes. Adam came out to our place to give us a quote. We found him to be knowledgeable and reliable. The system he recommended for us fitted our needs and preferences. We had some questions subsequent to his visit, and he proved to be very responsive to all our questions and concerns. Although the wait to have the system installed took a little time, the staff at Solar kept us well informed all through the process. On the day of the installation, the technicians turned up on time and were extremely polite and friendly. We are happy with their service attitude.
