Formula Sun Solar Reviews

We follow up with all reviewers after 12 months to see how their system is going since it was installed. These are all the reviewers who have responded to our 1 year follow up:
We are very happy with Phil Mercer and would recommend him Show additional information
Not only did we receive a great price upfront, but Phil was super easy to deal with. Not pushy like some of the others we encountered. Gave us loads of information, then time to digest it. Installation was great. Show additional information
Addition to previous review. Estiaan and Juan were top guys and proper tradesmen felt at ease throughout.

Thank you Sam. Show additional information
A great experience from start to finish, Phil was easy to deal with and had all the knowledge regarding the product.
His installation team at our property were 2 lads from South Africa who were very professional and knew their stuff, excellent workmanship and the site was cleaner when they left than when they arrived I think.
They even repaired a tile or 2 that I had broken on a previous visit I had made up on the roof.
We would not hesitate at all in passing on our 5 star experience with Formula Sun to friends and Family .

Prompt & efficient service from initial quote to final install. Show additional information
The whole team from the Phil and Walt in the office to the installers were all fantastic, very helpful polite and knowledgeable. Happy to answer any questions I had and replied promptly. Highly recommend them. Show additional information
On the day of installing Phils team suggested a far better location for the inverter than I thought would be best, and they replaced several old broken tiles I didn't know were broken. They also took the time to update and set up my old smart phone as a monitoring device. All the electical work was done professionally and tidied up some previous poor work far less than the best quotes I had. Show additional information
We enjoyed terrific personalised customer service from beginning to end. Phil, Walt and team were really helpful throughout and clearly value excellent customer service. We went with Formula Sun on the basis of a recommendation from a friend. The installers were friendly, punctual and efficient. The only minor detail that could be improved would be to include a thorough clean up after installation. But this is is a really minor quibble and I wouldn't hesitate to recommend Formula Sun to others. Show additional information

Formula Sun stood out from the others, nice to speak to someone who is not a salesman and who obviously knows their stuff.
They didn't try to up sell and quoted all the different brands. I was then able to speak to them again and had all my questions answered. I then had time to decide on the best system for us.
The install team were amazing and worked hard all day to get it done, Job well done.

Formula are good to deal with and initial paper work and panel placement was excellent.
John the instaler managed to get all the panels facing North so no shading a win for us.
Purchased 5 KW Fronius Symo inverter together with Longi 300 watt solar panels which was Formula Sun's recommendation.
Our first choice was LG panels but could not justify the price.

Installation was trouble free and all rubbish removed on completion.
285 watt panels were delivered first not 300 watt as quoted and invoiced.
The comment was they were probably out of stock and supplied 285 watt in lieu.

Were not impressed so Phil checked with the wholesaler and evidently they were picked incorrectly at their store.
300 watt panels were subsequently couriered so all worked out okay.
A case of buyer beware as i have no doubt if we did not check them the 285 watt would have been installed.

The system is performing as per conversations with Formula Sun averaging 39 to 41.9 KW per day for the last 8 days

We do have a system in place that picks up on potential warehouse picking errors, whereby we scan the panel serial numbers and our app automatically pre-checks with the client specifications loaded for the job. So this error would have been picked up and rectified prior to panel installation. It's unfortunately impossible to do this at the warehouse in the mornings as the jobs are pre-packed so well to avoid transport damage and simply forklifted onto the trailer.
Embarrassing in this case as the client picked up the problem before our system did, not our intention, just a case of human error.

Great to deal with, no BS just great price for good quality gear and installed very soon after agreeing to go ahead.

I found the installer through Solar Quotes but was not one of the 3 initial quotes through Solar Quotes.
Found Solar Quotes extremely useful for information, reviews, etc.

One quoted and we went with them but the service they offered was rubbish - didn't answer emails etc. Formula Sun were great.

This was a very tricky job, fully customised double storey Modern Architectural home with beautiful folded aluminium roof pressing, and then logical and discreet inverter position in attached garage... yet switchboard positioned under the stairs inside the house (I mean come on?).

So i'm not really surprised that my initial quotation was more than the others, but I'm also not very surprised that it may have been difficult to find confident installers for this job. But we are Fremantle specialists and we do like to work on the challenging ones. All good solutions in the end and great to add solar to an impressive eco friendly design.

Phil and his team were very friendly and professional. From the first enquiry to installation and beyond their service was impeccable.
The system is top rate and the installers did a great job.
Would definitely recommend them to anyone wanting to get a solar system installed.

I went with Formula Sun Solar as they were recommended by my son-in law and son, who were both impressed with their systems and the installation team.
I was just as impressed.

Phil the proprietor explained how everything would progress from start to finish and it did. The installers were just as good, answering all my questions on the day.

We have a few minor sags in our roof but all the panels sit flat on my roof. So well done! All the work was done very professionally and neatly.

After the install I got an email to say... We are only a phone call away if you have any questions or require help.

Bottom line: Excellent Service, Installation, Product, and After Sales Care.

Thank you Caroline, and it's true, as we stick to a small sized business you can email or call me at anytime and I will be fully conversant with your job. I think this does offer superior service than the giant retailers can achieve. Show additional information
Easy, efficient and good to deal with. Only criticism is having them show up to deal with a few loose ends without phoning ahead as we requested. Turned out ok since we were home, but if we hadn't been the work would not have been completed to our liking. Show additional information

I got a review from just about every solar bloke i could find, i had the good bad and the ugly quote on my place, Fromula sun solar shone through for us, we picked a local company with amazing reviews both on facebook and google. Phill listened and let me have the combination of inverter and panels i wanted. The installation was second to none. Im a Refrigeration Tech myself so i know a good install when i see one. The boys were quick polite and didn't leave an ounce of rubbish. Phill advised me that the neighbours tree needed to go as it would affect our panels, now im pleased to say as we wait for the tree to be cut down our panels are reaching their design output each day of full sun and we cant wait to see how it does once the tree is gone! We went with the Goodwe inverter after originally wanting fronius, Im glad we did same warranty same specs and with the option to buy extended warranty even further then the fronius would go made my mind up. Thanks team. 5 star Show additional information

A great company to deal with. No pushy sales tactics. Phil patiently and quickly answered all of my many questions before I made a commitment to buy. Very friendly team of 3 installers that turned up on time and got the job done efficiently, and left our property clean and tidy, just as they found it. A great system, and the Goodwe inverter we chose is producing more power than predicted, and has been very productive even on the cloudiest of days. One very happy customer!

Great to deal with..Gave me a quote, organised a day and came and fitted the system. Gave me a run down and set up the wifi so i can keep track on my phone..very professional..recommend Show additional information
I am 100% satisfied with every aspect of my dealings with Formula Sun. Firstly, I was given all the information I needed to make an informed choice of panels and inverter and further literature to read to assist with the decision making. The prices were better than other suppliers and I think the choice I made was the right one, offering top level components at a competitive price. I requested support and advice about the components from Solar Quotes and was very clear about what I was committing to purchase. I was not subjected to a hard sell campaign and that was a major factor in me choosing Formula Sun. The installation was delayed due to stormy weather but when the installation did occur, Phil Mercer met me on site to confirm that I was happy with the location of the components and to make sure any concerns I had could be addressed before the job started. The installation team was pleasant, clean and knowledgeable. They completed the work in a day and left the site spotless. It was great to see that everything was working before they left and my solar array and inverter is working well. I have received good follow up with maintenance information but I know that Phil at Formula Sun is only a call away. He has a matter of fact approach and I would not hesitate to approach him with questions or concerns. It was refreshing to deal with someone who wasn't using scare tactics and smoke and mirrors just to get a sale. I believe I have purchased an honest product from an honest company.

Being a smaller operation, the actual proprietors were directly involved with us for both quoting and installing and that felt heartening. I have already recommended your service to several other people in the past few weeks. Show additional information

I decided to go with this supplier because I believed they offered up to date equipment not superseded, they also gave a comprehensive description of what would be done, when and what would be used.
The installation was completed in a day and the premises where left in a tidy and clean condition
A totally efficient transition from grid power to solar/grid without a hitch

We obtained three quotes as we always do with any large purchase. Phil at Formula Sun was not the cheapest quote, but with this type of purchase we did not want a cheap job. Phil was quick to reply to all phone calls, emails and texts and provided excellent service before, during and after the installation. Nothing was too much trouble for him. Even when we had to re-schedule installation as the home was not ready on time, that was no issue at all. Installation was smooth and professional. Extremely happy with the entire process and would not hesitate recommending Formula Sun to anyone considering this type of purchase.

Thank you Sue,

There's a simple reason it all runs so smoothly, unlike a lot of solar companies we simply have not gotten too big and let things get out of control. I have the same partner doing the installs and I'm always the one giving the right bespoke quote for the right house. Quality solar, not sales spin or sausage factory installs.

Thanks you Ross, glad to hear you are happy. Show additional information
We are really happy we chose Formula Sun to install our solar PV system. Phil was very patient explaining things to us and when listening to our concerns. He wasn't at all pushy, but followed up later. He was also very accommodating when we had to change the install date.
The installation team were on time and they worked continuously throughout the day. Estiaan knew exactly what needed to be done but also took our preferences into account. The panels on the roof and the inverter on the wall are all perfectly placed.
We can't fault the company and service in any way and highly recommend Formula Sun to anyone wanting to install a solar PV system.

Choosing Formula Sun was a no brainer, after extensively investigating with a number of solar installers, I chose Formula Sun as not only did they provide an extensive quote with heaps of detail at a very competitive price, Phil left me to make the decision, there was no pushy salesman tactics, no follow up calls, just the right information provided and left with me to make the decision. Having said that, when I had questions that I wanted answered Phil was more than happy to spend the time helping me understand the benefits of the system and customising the options to ensure the most suitable system.

The full process from start to finish was simple! Phil organised everything with Western Power and Synergy, on the day, the team arrived installed the system (less than 1 day), ran through everything that I needed to know and ensured that everything was working.

After sales support is also fantastic, any questions/quieres that I have had about the system have been answered with no hesitation or frustration and extremely promptly.

I will not hesitate in recommending Formula Sun to anyone.

I would certainly recommend Formula Sun to anybody.

Phil and the team at Formula Sun did a fantastic job with our solar system. It is a difficult roof to work with and they did it with ease, the team was friendly and had the system installed in less than a day. Can't fault the price, service, warranty and the whole process was made so easy. I would recommend Formula Sun to anyone looking at solar. We now spend most of our time watching the app to see how much power we are producing :) Show additional information
Much better experience than dealing with a bigger company with salespeople. Nice to actually deal with the guys doing the installation! Show additional information
