I am very happy with our solar system
We had great service from this company and it only took 2 weeks. From a nice easy to read quote without dozens of attachments like the others, to turning up on time and leaving everything neat. Way more solar than we need right now but thinking of an electric car in the future.Panel rating: 5/5

I am happy with this companies service, we puchased 6.6kW as advised and it has exeeded expectations, very professional.13 August 2024
Really good service
We had a good experience with this company, we went for TW panels and Fronius inverter. Pre-installation was fast and Phil kept us informed of the process. The two guys turned up as arranged and really seemed to know what they were doing, set up the wifi and cleaned up. I even went up on the roof for a look and all seemed very neat.Panel rating: 5/5

Professional instal
A friend recommended FS and we had a good experience. The quote was good but similar to others. Install only took around 2 weeks. System is making around 20 units per day in mid winter so as predicted in quote.We have had some storms and no leaks so far.
All in all a good experience and I will be recommending to others.

Installation of Formula Sun Solar System
I went with 18 x Longi 370 watt Panels. I changed from Goodwe to SMA which they were happy to do and we had a smart meter thrown in....Had them installed on 4/1/21The installers were also great and were happy to rejig the configuration of panel layout. Left with everything tidy and Brett was very helpful with setting up smart meter - Yes it was working when installed
Pania from Formula sun organised the new Western Power meter and chased it up after discovering that
Synergy did not process a Work Order for Western Power to change meter out, which resulted in a delay
I am having problems getting the SMA smart meter to work on my mobile & computer. Formula sun have sent a technician but still not fixed. He was supposed to come again this week but COVID shut down has put a halt on this.
pania has been following up on it with me
8 months later we asked Gerard: "Are you happy with the performance of your system so far?"
Yes, it performing at were I though it would, and we are also becoming more awareof ways to reduce more consumption, ie turning unused tv's off at switch, and changing cloth washing
times etc
Foot note: Would have liked a courtesy call maybe from Formula Sun, which would help their goodwill even more

Good
Very helpful, explained things factually and objectively, well priced. The people I spoke with weren't annoying salesman trying hard to push a sale, they were just knowledgable and factual. Shared lots of details of different solar systems and why they use the brands that they do. Great company and would recommend.Panel rating: 5/5

System OK but problems with inverter took a while to resolve
Installation went OK and was generating power from day 1 but there was a problem connecting the inverter to my Wifi to provide data reporting. This took several visits and probably about 12-15 hours on site to resolve and turned out to be a faulty Huawei wifi dongle – system connected fine once this was swapped but was almost 3 months later.Inverter rating: 3/5

Please be aware that Phil from Formula Sun Solar had a huge heart attack and has been off work for around 18 months. In the meantime his staff have been running the company during his convalescence. This has gone well up until very recently. Phil has contacted each of these customers and resolved the issues, which were only warranty documents and approvals, the installations and workmanship was first class.Phil is now back running the company and easing back into work, all the installations are as ever done by Power Breeze Pty Ltd.
It should be noted that Formula Sun has been with Solarquotes for over 7 years and always had the highest customer rating in the Perth area.

Stressful - awful experience.
We had virtually the same experience as the review on this site by Sarah. Formula Sun did not complete the necessary paperwork for Synergy and Western Power, although I did send numerous follow up emails and messages to Formula Sun. Thus the system was not registered..Formula Sun emailed me numerous times advising that the registration was completed. When following up further I got plenty of promises that they would ring me back. I did not get any return calls.
I was aware the Synergy had not changed the meter and thus in desperation finally contacted them directly. They advised me that the Distributed Energy Buyback Scheme (DEBS) application had not been completed by Formula Sun. Synergy were excellent and helped me fill out the application. I then contacted Western Power who informed me that the form should have been completed PRIOR to installation. Western Power were fantastic and helped me a lot, so after a delay of 7 weeks the new meter was installed.
Whilst the installation was good the whole saga was extremely stressful and upsetting at times. I would not recommend this company at all as the pre and post installation customer service has been appalling to say the least.

Quick installation
Hard to know the quality of the install without going on the roof. Office line was helpful in answering questions on what to select. It was done only a couple of days after agreeing to proceed which was great. Wasn’t much time spent by the installers in terms of explaining the system but will call formula sun once get full billing period covered by the solar.10 February 2021

All went smoothly
Dealt with Pharnia who was helpful throughout. I had a good idea what I wanted and discussed this; I found her input and guidance useful. Pharnia organised the grid connection and again that process went smoothly.The actual installation went well and I was pleased with the two guys who completed the work. I felt there was a care factor and they took pride in what they did.
Everything has worked satisfactorily since the installation and I would have no hesitation in recommending Formula Sun

Efficient Installation
Quoting process was handled online. Formula Sun provided all the details for my review and answered all my questions.The installation was completed efficiently on the scheduled date in approximately 4-5 hours.
Unfortunately the grid connection was not timed to coincide with the solar installation and I had to wait another 4 weeks due to the Xmas break. Considering the life of the system, it was a minor inconvenience.

Fantastic job
Easy to deal with If system is as good as Tristan and Aaron were on the install it will be great! Great service all the way around13 January 2021
Very Professional
The company provided a quote very quickly after request. Customer service is great. Were able to answer all my questions over the telephone. Offered a number of dates for installation. Price was very competitive with other quotes. Installation was fantastic, the tradesmen were very professional, arrived on time, neat tidy work and answered all my questions. Grid connection has still not occurred although advised by Formula Sun they have contacted Western Power twice. I trust they will continue to follow up this until resolved. I recommend this company.Panel rating: 5/5

Happy but not!
The whole process was prompt and detailed by email (using Google earth and Nearmap - no site visit ) but I did order a Fronius inverter and was expecting installation of to be in the garage. I asked do they need to inspect before as I perceived access would not be straight forward but was told not necessary.Unfortunately when it came to installation they couldn't get cable access from garage to the switch board so they inverter had to be mounted externally on a side wall with some surface conduiting and they installed a Goodwe inverter.
The installers were very good and did a great job in minimising surface conduit and job was very neat and they installed a shade structure over the inverter.
Overall the system is working as expected and the inverter would have been external using other companies.
Would recommend Formula Sun to others but get a site visit by the installer before signing off.

Professional install
Sales / quoting was prompt and polite.Install was arranged quickly.
Installation went without a hitch. The panels are positioned so they are not visible from the front of our house as requested.
The inverter unit was positioned well also.
No mess was left behind.
Customer service was great. A very smooth process. We are very happy and highly recommend Formula Sun.

Fits the Bill
Wasn't seemless but these things rarely are. Only weird thing is a Formula Sun use a mans buisiness email (assume the owner) yet never actually dealt with him in any way, always dealt with a lovely helpful lady that coordinated the job just fine. All in all happy with the system for the price and I added an extra job for the installer that was catered for with no fuss. Install was nice and neat, happy with the result.

Original Review on 16-03-2020:
Installation faultless
Following the prompts from Solarquotes I got contacts, plus a few others from my own research. I narrowed down my choice of inverter and panels from the reviews, and other sources, and finally chose Formula Sun to do the job, even though my contact with them did not go well. The final decision was made based on them being able to supply the hardware and the rave reviews for their installers. I was not disappointed. They arrived on time, made adjustments to the plan as the panels ( 19 of them split between east and west facing roof surfaces) were different sizes on the plan! Todd and partner expertly adjusted the plan and made them all fit. They worked quickly (in 40c + temps) and finished on time.8 months later we asked Janet: "Are you happy with the performance of your system so far?"
The system has not disappointed at all, and I look forward to the time when I can install a battery to complete the system.27 October 2020
Informative and simple
The team contacted me straight away. My roof is shaded. I was told exactly how many solar panels I would need. no sales pitches to buy bigger or better. How the panels would work was explained to in clear and concise terms.Installers were polite and explained exactly want they were doing to my roof.
Overall the experience was painless and the team were friendly and honest. Well done

From start to finish A++
Having asked for quotes through this website, this company were the only ones to send a fact sheet and a quote without the hassle of a site visit and a pushy salesperson which is the one thing I dreaded happening.After being happy with the original quote I expressed some resignations that perhaps my roof being a smaller than average size, may not fit the original quote. Pania arranged the installers they use to site visit and he expertly gave me his opinion and a different panel design was offered with slightly smaller panels.
Due to this the quote was revised slightly cheaper and after some time to persuade my wife that solar was the way forward and cost effective I was able to give the go ahead.
The install date was swift(withing the week), Pania and Phil organised the changeover of the meter with Synergy/Western Power, and the day of install the meter was changed over and the 2 gents installing did a stellar install and I couldn't be happier with my install
For reference JA solar panels(due to delivery delays my original Risen panels were unavailable) and a Goodwe inverter.
The installers got my inverter onto my wifi inverter, the app downloaded, and I am now obsessed with looking at the KWs my panels are generating every day since!
I would have absolutely no hesitation recommending Formula sun for this install and the products so far so good!
Thanks again guys

Fantastic Solar experience!
From start to finish these guys were excellent. I was really pleased with the knowledge of the guys in the office and they answered all the questions I had and gave me great confidence in there ability to provide a great service, they made sure that their technician called me when I had a question regarding install that the office staff could not answer. The team they sent for installation were excellent, very polite, friendly and a pleasure to have in our home. I can’t recommend these guys enough, I have already sent them two more customers who have also been very happy with their work.01 October 2020
From quick quote to amazing installer experience
From the moment we spoke to Formula Sun we realised they were a local business and not those Facebook marketed resellers. From speaking to the owner and others who took the calls and emails we went from quote to install on a day of our choice in 2 weeks. It wasn’t easy for them, a 3 storey townhouse, rear house, steep driveway and required an all terrain cherry picker. Nothing was too much trouble. Today as described at 7:30am cherry picker delivered by 8:30 the team was on the roof installing a 6kw set of panels and doing the electrical on the ground floor. Clean and tidy worksite, no mess left behind, friendly team who took the time to demo the app and how the inverter worked, Before they left early afternoon we were generating over 3000 Watts. Great local business who really made us feel like they cared.Panel rating: 5/5

Great company, great service, excellent installation.
The engagement with Phil and the team was a pleasure. The team sent out did a fantastic job and I was very impressed with their workmanship and how they were able to meet our aesthetic requirements. Their solution was also excellent value for money.02 August 2020
Very happy with Formula Sun and my new solar system!
From start to finish with Formula sun was easy and informative. It was the only company out of the 3 through SolarQuotes that sent me a quote straight off the bat- the other 2 required me to ‘book’ a phone call (a bit hard when you drive for work.) Quote included different panels and inverters- all priced out.I had questions about shading and they came up with a solution (that neither other company did.) Were also happy to answer ALL the questions I threw at them.
Once I decided to go ahead I had an install within 10 days. They organised everything with the ‘Grid’ provider. The guys who came out were great- friendly, professional, on-time and knowledgeable. Talked me through some options regarding inverter placement. They tried for the most ideal option but to their disappointment (they took great pride in their work) it couldn’t be done due to the house.
They then tried to do the job as visually appealing as possible- but again issues with the house and had to call it a day. Came back 2 days later, finished the install promptly, patched some holes they didn’t end up using and still tried to make it look good (which it does.)
10/10 would recommend.

We recently had a solar system installed. We're happy with the performance of the system so far, and pleased with the quality of the work done by the installers.

Great value and system performance
Non-pushy quotation. Install was good, could have tidied up the roof a little better but not bad. Communication by email seemed a bit rushed but generally responsive.Great communication on the phone with the install team regarding position/layout of modules and inverter.

Quality installation and system
The quoting process was a desk based one, but they had all the details and got it right. The installation itself wasa bit bumpy with a few missed dates due to sickness, weather and other assorted issues that couldn't be helped. The work though was high quality. The customer service from the installers was very good and they came up with a range of installation options when they were not able to instal on time.8 months later we asked Doug: "Are you happy with the performance of your system so far?"
Yes it has. I would get more of the same from Formula Sun but the local WA elecricity supplier caps sizes to a 5 Kw array. I would like to place some more on the front and the western side of the house to get the full duration of the sun but the 5Kw size limits me. But more than happy with the instal and the product.10 May 2020

Hassle free, great installation.
Phil at Formula Sun was receptive to my questions and helpful in achieving hot water diversion in the most cost effective way for me. The process was low friction and we went from quote to result with hardly a thing to stress about. Great service :)8 months later we asked Ben: "Are you happy with the performance of your system so far?"
Absolutely! The ability to monitor the production vs consumption vs self-consumption has been very valuable in shifting our consumption habits to get the most out of the system.05 May 2020
Solar at Last!
The initial contact with Formula Sun was informative and helpfulThere was some miscommunication within the office re installation plans which caused me to reconsider my options.
I went ahead with using Formula Sun after further discussion. I was happy with final installation process.
The installers were polite, tidy, punctual and informative.
The engineer who set up the app once meter was altered was brilliant.
Would recommend Formula Sun.

Super Easy, Super Quick, Super happy
I requested a couple of quotes through solarquotes on a recent Friday, one being Formula Solar.First tick - Phil from Formula Solar responded that Saturday with a couple of options and layout of the best panel arrangement, a super quick turn around from the quote request. I waited for the second quote to come through for comparison sake and also reached out to synergy for a quote as well.
Second tick - After doing some thorough research I decided I would like to pick different panels and inverter to the ones suggested by Phil, I suggested the change to both companies that quoted, Formula Solar rapidly replied that they were happy to supply both the panels and inverter that I had chosen. The other company would not change the panels as they had a set brand.
Third tick - After a bit of backwards and forwards with quotes and the like, Formula Sun on Monday let me know they had a vacancy for an install on that Thursday - happy days. Formula Sun also listened to explanation of inverter location and upgraded the AC cable to accommodate.
Fourth Tick - the install was super easy, the installer arrived on time, listened to where I wanted the inverter, placing it in exactly the right spot and also listened to my slight change in panel layout location, happily going ahead with what I had requested. The installation was completed quickly and easily with no mess left behind, Its a great neat job too.
Fifth Tick - the after sales contact from Phil has been great as well - even recently asking for log in details to check the inverter is working correctly.
I have absolutely no hesitation on recommending these guys - even if you're like me and think "you only get what you pay for - the more expensive guys are obviously better" not in this instance, that's for sure!
Hint - if you are wanting to track your power in and out, get them to install a power meter - my inverter is a Fronius - so a Fronius Smart meter means I can see how much I am using and how much I am generating.
My days are now filed with constantly checking my solar gainz, turning appliances on and off to see the effect on power drain - it's been great to have something to do while taking a break from working from home due to COVID-19!

Don’t pay until you get everything
They were very quick to respond to the request for quote and the price was reasonable. The information I was quoted on was not what I got - more panels than I was told were being installed and the installer couldn’t explain why and a different (better quality) inverter because of supply problems. Installation was ok, but disappointed that they left some of the panels dirty with tile dust.Post installation has been terrible - I had to keep chasing for the login details for the Huawei and only got it by only paying half the bill. Then made the major mistake of paying before receiving warranties and manual, which he promised were being sent two weeks ago.

So Easy
Dealing with Formula Sun was easy and efficient. I went with Formula Sun based on their response to my inquiries, the discussion we had when Tom visited, the fact that they were pretty local and well established. They were not the lowest price, but I compared ratings and reviews of the other installers, and decided the premium was worth it from a risk/afterservice perspective. They have had a long association with Power Breeze who did the installation and the guys who came were really polite, efficient, easy to deal with and very tidy. The 6.6KW system, wiring and inverter is very neatly fitted and working as it should. Installed in a day and only a week after agreeing everything. Formula Sun also took care of Synergy and Western Power so no stress whatsoever on my side. I recommend them highly.Panel rating: 4/5

How can it be this easy!
Received a quote from Phil that was no b.s - just honest advice about panel locations, system size and brands. Once I gave the go ahead was able to squeeze me in straight away. The installers arrived and checked a few things with me re install locations then off the went. All done in a day and connected up ready to go. Only delay in the process was waiting for western power to upgrade my meter. All done now and producing about 40kwh per day over the past few days - plus we start feeding in from about 9am which is amazing. Haven’t seen a statement from Synergy yet, but I’m hopeful the days of +$500 Bills are long gone!Panel rating: 5/5

Excellent service, installation and competative price
We highly recommend Phil and the Formula Sun team in WA. They were recommended by word of mouth by our neighbours and we will now recommend them ourselves!Excellent service, installation and competitive quote for superior quality equipment, they organised the paper work and set up with Western Power. Installation within days by good installers who went the extra mile to do some complex wiring to set up the inverter as we requested. Tidy, polite, punctual.

Fantastic service
Formula Sun were fast responsive and able to explain things for us if we needed more clarification. We used optimisers to address a shade issue and have a system that is generating very well without any north facing panels.Formula Sun did all the leg work to organise the new digital meter and grid connection.
Installation occurred two weeks from first contact. Installers turned up on time on a 40 degree plus day. Very impressed!!!
I am tracking power generation with the WIFI, consumption and exports on the digital grid meter. We’re winning already!!

Good all round. Very knowledgeable and professionalInstallation via 3rd party also top guys.
9 months later we asked Ernest: "Are you happy with the performance of your system so far?"
Since installation (last day of April 2019) we have only had to pay one bill mainly due to the cost of the new meter. The last 2 bills we have had credits of $26.00 and $42.00on our last bill, we have produced more than 1 Megawatt of electricity for each of the last 5 month. Our FIT is only 7.8 cents Kwh, we buy at 28.8 cents Kwh and pay $54.00 aprox
fix charges.
Personized customer service
I had great service from this company and it only took 2 weeks. From a nice easy to read quote without dozens of attachments like the others, to turning up on time and leaving everything neat.Dealing direct with a smaller business with years of experience an hassle free service is a pleasure hard to find at times today.
Installers where mature experience tradies who actually worked hard ,an in on 39° day.
Recommend highly.
