100% would recommend!
Koala Solar has been magic. The quote was easy to get, customer service was really friendly and engaging without being pushy. Communication during the lead up to installation was clear and personable. The install team was great - really friendly and approachable yet professional. They came on time, worked quickly and efficiently and cleaned up at the end. I would 100% recommend Koala Solar for your solar panels!24 May 2026

Completed Early, clean and efficient
Koala installed our original solar system and, with the great experience that was, it was natural we would look for a quote from them. Adam checked our old system, listened to what we wanted to do and designed a system to suit. An installation date was agreed and the installers arrived on time. The installation was carried out very efficiently and they cleaned up after the installation really well. All waste materials were removed from site.Due to the configuration of the system, there were a couple of issues with connecting them but the installers figured out a way to get it done and left me with a Sigenergy system that has worked efficiently from day 1.
Highly recommend Koala not just for the install but their pre-and post sales service.

Trouble free install and great service
Koala Solar was recommended on a social media group, and pricing was competitive compared to other quotes we received. The team was helpful with quotes and questions we had, and was able to bring forward install by a few weeks which was great. Install on the day went smoothly,. highly recommend18 May 2026

Great service - professional installation - Koala Solar!
I can't fault the experience with Koala. I was looking at a couple of providers at the same time for different solar only and solar + battery solutions following the purchase of an EV. The sales/quoting team at Koala were great - very helpful with finding what suited my needs and great knowledge of the products used. I found other companies to be pushy and trying to upsize the system beyond what I needed for extra cash.The admin side of things was also handled very smoothly. All communication was prompt and relevant rebate paperwork was completed for me ahead of time.
I did have to wait a while for the installation but I expect this is to do with the popularity of the business. Quoted in December 25 and installed in April 26.
The installation team were friendly, professional, polite and cleaned up after themselves. All aspects of the installation from racking, wiring, placement of assets was done to a very high standard and I would use them again if I moved house.
I was shown exactly how to download and use the Sigenergy app. All questions I had were answered and the system starting working exactly how described!
Would 100% recommend Koala solar to anyone!

Quality install & value for money.
Koala Solar where fantastic to deal with from choosing a system & booking installation date. The orientation of the photovoltaic panels & new inverter positioning due to future block subdivision where all addressed. Installation went extremely well & where on time . All staff where polite & worked efficiently. All old photovoltaic panels & inverter where taken away, wall holes sealed & work site was left clean. Stewart was extremely helpful with setting up the fontus inverter app , he stayed back & made sure I was completely satisfied. Thank you to all the team at Koala Solar !Inverter rating: 5/5

8kw JA Solar Panel's and a 16kw Sigenergy battery with Gateway
Awesome company to work with. Very upfront with pricing each individual item instead of as a package deal like some other quotes I had.From the initial quoting process with Sean through to the scheduling with Kristie and Shyniah and the install team was very professional and they always kept me in the loop.

Smooth process from quote to installation
We were recommended to use Koala Solar by a colleague who had heard good feedback from other sources and we approached them for a quote a few months ago. We received a quote very promptly and after a few queries and changes, we decided on an option to suit us.Koala Solar explained what to expect during the application process and kept us fully informed of any paperwork that was needing to be completed and followed up throughout the whole process.
Once the quote was accepted, an installation date was nominated for a few months ahead and on the installation day the Koala Solar crew of 4 turned up on time and were straight into getting the job done. Each one had their specific tasks and ensured that the work was completed promptly and efficiently, with the entire installation process being completed in just half a day. The guys cleaned up thoroughly and didn't leave anything for us to clean up.
The guys went through the software install process and made sure that we understood how the system would work, answering any questions before they left.
We are very pleased with the new installation and are happy to recommend Koala Solar for future work.

Battery Install Done Well
Received a competitive quote to add batteries to our existing PV system in early in January 2026. Tweaked the quote a couple of times to add an extra module and increase the inverter size. All revisions quickly acknowledged and updated.Koala Solar already very busy so job booked in for late April. Received several emails from Western Power advising our application was being processed in the months preceeding install day and all was good to go when the team rocked up to install the batteries.
They took note of my description of the house construction, water pipe runs and preferred location for equipment and did their best to accommodate my wishes. Didn't all go to plan but perseverance paid off and we now have a neat, functional battery system with 3phase backup and an EV charger.
All rubbish disappeared into the back of their van so job site left spotless. A quick tutorial on the app was given and we were provided with advice on how to get better acquainted with the system.
Happy with the process and outcome.

Great Service
After having a negative experience with another Solar installation company I turned to Koala Solar. The customer service was excellent, the girls in the office made the paperwork process seamless and the installation was very efficient and tidy. There was one fastener that wasn’t down fully and the guys came back and fixed it promptly. A great company that delivers excellent service and quality.07 April 2026

Great buying and installation experience.
The process with Koala Solar was great from start to finish. Effortless sales and quoting experience and kept me in the loop throughout the whole process. Their pricing was fair and transparent and they came out with a better deal than some others wanted for smaller systems of the same brand/models - and they could install it sooner than some of the others.Arrived exactly at the time/date in a punctual manner and their team was immediately at work setting up the system in an efficient, tidy and professional manner. Everything went up in less than half a day as there was a team of guys all working on a different job so there werent any delays. The guys were great, kept me informed through the day and I would strongly recommend them to anyone looking for a new system.

Fantastic Customer Service and Seamless Installation
We had been looking and reviewing the solar and battery installation for some 12 months and had spoken with many companies along the way. Some very good and some not so good. It was all becoming very complexed and confusing and whilst we thought we had final decided on an installer, we spoke with a family member who had just finished having their solar system installed on their two storey home.They detailed what interaction they had with the team at Koala Solar and the support and advice they had received. So we decided that we would talk to one more installer, and that was Koala Solar. We are so glad we did, not only were they able to work with us through the number of questions we had, they were patience and very supportive of our requirements. The team at Koala Solar went through the options and system available and provided strong documentation is support of the proposed system. Their Team was not pushy or dismissal of our questions and thoughts around the best system for us.
We finally decided on a great system with top 5 rated products, that came in cheaper then the bigger installer that we had contacted.
On install date, the team were professional and well presented. They walked us through the whole system and we are more than happy with the system.
Well done Koala Solar, and I would strongly recommend them to all who ask.

Smooth and sound from start to finish
I had a great experience with Koala Solar—the team was professional, knowledgeable, and made the whole process smooth from start to finish. The installation was quick and the technician’s carefully went through and showed us the ins and outs of the install.27 February 2026
Fantastic job
This is the second time I have commissioned Koala Solar to install a solar panel system to my home. They are exceptionally efficient and organised from the quoting stage, right through to the installation. The office staff are courteous and very helpful and the installers were just so efficient and knowledgeable that it was installed in no time. Was shown the website and installed the app so I can see what is happening with the energy use. Such a credit to their employer. Can highly recommended Koala Solar for anyone in Perth WA looking to find a credible, honest and reliable Company to install their solar panels. Well done, once again. SandraInverter rating: 5/5

Quality Installer
Koala Solar is a very professional, quality installer. The sales process was thorough and all grid connection and rebate applications were completed well in advance of installation. The install crew were very polite, on time and tidy, clearing the site upon completion.Koala Solar have become very busy and in great demand, so the handover process was a bit rushed. However, Customer Service was available to answer any additional questions. Therefore, I would be very happy to recommend Koala Solar.

Review
We had a previous system installed by Koala Solar at our previous address. We were happy with their product and customer service then so it really was a no brainer to go with a reliable company.Once again we were very impressed with the customer service from start to finish. The two guys who installed the panels and inverter were very efficient, made no mess and explained how the system works and helped set up the app for monitoring the system.

Exactly how I wanted it.
Quote I requested was complex but Koala managed my expectations very well.Koala was courteous and informative, came a did a pre install and listened to my concerns and tailor made the Tesla PW 3 so it showed no conduits and a floating switch just like the glossy brochures.
Delivery was a bit of a wait which is understandable considering the government incentives were being offered at the time. Yet delivery day was met and install was completed on the very day.
All the paperwork required for connection was handled with minimal required interaction which was a bonus.
And a very pleasing outcome as well as I received my first full usage account from Synergy since install and is well onto the way of a very fast payback.

Honest price and honest service. Hi 5!
I recently had a 12kW system and 32kWh Sigenergy battery storage installed by Koala Solar, and I couldn't be happier with the experience. I did a lot of my own research beforehand and knew exactly which hardware I wanted. After finding Koala Solar on the manufacturer’s preferred installer list, I reached out via their online form.Compared to other companies I dealt with, Koala was a breath of fresh air. I had other sales reps being incredibly pushy, trying to steer me toward different equipment, or providing quotes that were wildly unrealistic, where some were even $10,000 more expensive for a similar setup.
Koala was the total opposite. They were prompt, honest, and very competitive with their pricing. Even as I evolved my installation plan and requested amendments to the quote, they were responsive and patient. There was a bit of a lead time for the install, but that is clearly a result of their popularity and the current rebate demand. It was well worth the wait.
The installation was completed yesterday by the owner, Stu, and his team. They were on time, professional, and all-round lovely fellas. It was reassuring to see that the entire crew were qualified electricians, which gave me a lot of confidence that it wasn't some fly-by-night operation.
The system is performing brilliantly. Watching the harvest and storage levels today has been great. My only regret is not going even bigger on the battery! If your budget allows, I’d suggest getting as much storage as you can while the rebates are still active. I would highly recommend Stu and the Koala Solar team to any friends or family looking for a quality install.

Seamless install, excellent communication, and high-quality workmanship
Koala Solar provided excellent service from quoting through to commissioning. The salesperson gave clear, practical technical advice over the phone and by email, and the admin/scheduling team were responsive and flexible in accommodating changes.I previously had to cancel an installation I’d signed for and was not penalised. Nearly a year later I was able to restart the process and move forward with an updated system, which I appreciated. Before finalising the decision, a co-owner/supervisor visited the site to assess the house and confirm the installation plan.
On the day, the installation was carried out by the same supervisor and their team. The work was completed neatly and efficiently, commissioning was smooth, and the finish was clean and well-presented. All rubbish was removed and the team made a clear effort to make the installation look tidy and professional.

Very happy with Koala Solar.
I found Koala Solar very helpful. They were happy to answer my questions when I rang them. They were very knowledgeable about the government rebates and helped me through the process if I had questions. They arrive on scheduled date and time, and did a professional job on the install. It was no problem to install the components and battery where I prefered them, and they were the cheapest quote. They arrange for the grid and meter upgrade and connection.I have had the system now for 3 months, and it has work as designed and without fault. The size of system that Koala recommended was spot on for our family usage, and we are exporting to the grid everyday.
Great job Koala Solar.

Problem free, from quote to instalation.
This was the third time we have worked with Koala Solar. They Installed our solar system, our heat pump hot water system and recently they installed our Solar battery. I am happy to give this company 5 stars from the initial contact requesting a quote, to the day of installation. They arrived at the time they had indicated, and their technicians were knowledgeable, friendly and polite. I found this company to be professional and reliable at all times, and would have no problems in recommending Koala Solar to anyone who is considering any work of this nature.13 January 2026

7.6 kW solar system with 16.12 kWh battery storage
The process for getting our quote was straight forward, we simply contacted Koala Solar, met on-site with their representative, discussed options, the process for state & federal rebates, financing considerations, and what size system would best address our needs. We received our quote shortly afterwards and engaged there services. Koala Solar came highly recommended from other family members that have used their services and we would highly recommend them too.The overall installation went very well and was much quicker than we anticipated. The crew was very punctual and great to work with at our home. The overall installation was completed in just under 4 hours, which included an excellent start-up experience. Our property was very tidy when they left.
We look forward to working with them again when we take the next step to adding an EV charging station.

Highly Efficient Team
The Koala team is highly efficient. The 14.25kW solar system with 24kWh battery was installed in less than 5 hours. Amazing work!Very straight forward quoting process, after all relevant information was provided to Sean, a formal quote with all analysis was provided. So, it was a matter of fine tuning with various options available and made a decision. Altogether I received 3 quotes from Perth's top installers, all with similar specification. Koala was chosen as their quote was the most competitive.
The Koala team turned up at 7am as agreed, worked their way through and had everything wrapped up by 11:30am. Site was left clean and tidy , phone app was setup and demonstrated. How good could that be !
Three cheers to the Koala team for their efficient work.

Fronius Reserva 18.9 Kwh install
Installed in Nov 25 a Fronius Reserva 18.9 Kwh battery on top of a 2023 Fronius 5 Kw GEN 24 with 6.6 Kw of Trina panels. Both of these installs were done expertly by Koala Solar. Whilst not necessarily the cheapest option, their team of installers and office staff are second to none and I have no hesitation in recommending them to others. There was also a Fronius Wattpilot 22 Kw charger installed by another firm in 2024, due to lower quote than Koala's - in retrospect this was an error, as it would have been much better to have the whole system installed by one company.Panel rating: 4/5

Koala solar install
Just had our solar panels installed by Koala solar and they have been helpful in terms of queries and communication throughout. We were abit unsure on which company to go with or the brand at the beginning but going with Koala solar definitely helped eased our concerns. They were punctual on the day of installation and the guy showed us how the app works and gave advise on how to utilise the solar. So far, it’s been a great experience with Koala Solar. I would highly recommend going with Koala solar after all it’s something that sticks to the house for a long time.16 December 2025
Job well done
From the outset a very professional approach. Any queries I had in the sales/quoting period were handled well indeed. Ongoing communication was excellent.On installation day, the friendly crew arrived within the specified time frame and immediately set to work.
3 1/2 hours later the job was done and help was overfed and accepted in setting up the app and pc and interpreting the system power flowchart.
After job clean up was good.
