Formula Sun Solar Reviews

After tormenting who to go with I decided on Formula Sun because of their competitive price for the quality of the system fitted. Phil was very informative as I relayed many questions to him and his business partner Estiaan did a very neat and excellent job of fitting the panels to the roof and connecting the wiring to the inverter and meter box etc. After one week the power use savings are amazing so it is all working well. I highly recommend potential buyers of a solar power system include this company for consideration when going through the process of deciding who might be best for them. Show additional information
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. Show additional information
A great local (Hilton/Fremantle) solar company!
Phil and Estiaan did a great job with our solar system from initial visit to finished job. Phil took the time to compare and contrast panels and inverters with me as I had a lot of questions. Eventually we ended up choosing a 6.6kW system; x22 Longi Solar [LR6-60PB] 300W panels (with sleek black frame to match our roof) and GoodWe GW5000L-DT three phase inverter (in fire engine red). Timeframe was exactly 3 weeks from sending deposit to job completion. Estiaan arrived on time on the day of install and went about his work very conscientiously, which resulted in a neat and tidy job, both on the roof and on the inverter. The Goodwe app is also a really good way to keep an eye on what the system is making each day. Would happily recommend Formula Sun to anyone. Thanks Phil and Estiaan!

Very happy to recommend Phil Mercer and his team from Formula Solar. The whole experience was great. 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.

Formula Sun was a Great company to deal with, offered plenty of information and answers to all of my questions, and I had many.
Very happy with the price and product so far.
Installers were on time, friendly, efficient and helpful.
Easy to deal with Phil, no high pressure sales, I asked the questions , he gave me the answers, and he left me to make up my mind.
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
Which company to choose is the biggest hurdle. I chose Formula Sun as they were a local owner operated company that had been going for a long time in our area. All of the quotes I received seemed to be quite professional and competent but Phil from Formula Sun certainly was the least pushy and goes into the most detail in his written quotes.

Lead times were only 3 weeks and we were informed when Synergy and Western Power had approved the system. Phil called us the day before installation as a reminder.

When it came to installation day, Estiaan, Phil's partner and his apprentice completed the job with no fuss. What Formula Sun say in their marketing about no subbies and an owner operated business are true and for me represents the best option.

All up a highly professional local service and the system is performing very close to projections outlined in the quote.

Hope this helps

The installers arrived promptly, worked very efficiently and left the site clean and tidy on completion. On completion of fitting detailed instructions were given and then they kindly installed a very helpful app on my phone to enable us to view the solar progress daily. Money very well spent. We would thoroughly recommend them. Show additional information
I was so pleased I’m having them install the same system at a rental property. Show additional information
Excellent value (I got multiple quotes and a few could match, but nobody beat it.) Very knowledgeable and communicative vendor who takes pride in their systems and service. Happy to discuss technical and financial aspects in detail (e.g. I didn't know an inverter is limited to 5kW to be eligible for REBs from Synergy, or that you can oversize your panels relative to the inverter, which has a number of other benefits.) Excellent warranties and a good awareness of durability issues with roof mounting systems (I'm a corrosion engineer so I was pleased to see this detail.) Very good experience - it would have been hard to do better! Show additional information
Phil was very honest and not so pushy, the installers were good and friendly. Very happy, thanks for you assistance.

Excellent tidy installation, to a high spec. I hardly knew they had installed it. Highly recommended. Show additional information
Im really happy with my solar system. I have only had it for a few weeks but the installation was quick and it seems to be working great. One of my friends had a system installed by Formula Sun so they recommended them to me. Phil was very helpful and I had a lot of questions but he was able to answer all of them. Compared to the other quotes I received I think I got a very good deal and am quite pleased with my system. Show additional information
The system has only been installed for less than a month; as yet I haven't received a power bill so the pudding has yet to be eaten. That said, so far everything seems to be working well, the installation went very smoothly and faster than I expected; so at this stage I am extremely happy with the hardware I chose and with the installation.

Phil was prompt, thorough, knowledgeable and personable. We decided to go with him primarily because he offered good quality products tailored to our needs at a reasonable price, and also because he has experience installing solar panels on old houses, like ours. Show additional information

I wanted solar to save money. Phil provided not only the biggest system, but was over $500 cheaper than everyone else. Panels and Inverter both have 10 year Parts and Labour so no worries there. I even get an email daily showing me how much power I made the day before - nothing could be more simpler. Show additional information
Top system. Phil had really good advice and I asked a lot of questions. I'm really impressed with the system. Even though we chose Chinese over expensive German brands the system is really performing fantastically and above expectations! The installation was really neat as well, internally routing all the cables and a very professional finish. Really happy I went with solar, should pay back in a bit under 3 years.

We can not recommend Phil and his crew highly enough.There was no high pressure sales techniques just good honest and friendly advice. Phil helped and gided us through the hole process no questions went unanswered. We did get quotes from other installers and some and some of those were way out there past mars we even thought one wanted to move in with us after 3 hours of power selling phoning his manager and telling us if we signed on the dotted line now he could do us a big favor and fit us in 6 weeks and we would have a 3 kw system for $7000 we didn't sign he left in a huff . With Phil and formula sun it was completely different no hassle all done on the phone great communication 3 weeks from start to finish and the fitters were brilliant in and out in a day neat tidy an excellent job.Good quality panels inverter and fixings and a very good warranty 5.5 kw system for under half the price quoted by others . We did get cheaper quotes but none had better reviews than formular sun if you are thinking of getting solar fitted give Phil a ring. Are electric use is now 78 cents a day down from $3.50 a day and we generate more than enough to cover it. We could not be happier and can not recommend Phil and his company highly enough Nick and Mandy sainsbury loving the sun :)) thanks Phil. Show additional information
I choose Formula Sun because they were local (Fremantle) but also offered great service. Phil explained that he would have to measure our roof before accepting the order as it was an old roof and there was not much room, we thought that was a good touch as nobody else mentioned this. As it turned out he had to drop a panel from the original layout sent through and move the tv antenna, was good to have all this sorted before the order was placed.
Everything else went fine, trouble free and we have not had any problems for over 4 years now.

5KW system SMA and Solar world was installed 20 December 2013, and has been running perfectly for almost 4 years to date. Its produced 30MWh, average 22 kwh/day.
A couple of the isolators were recalled after installation. Formula Sun notified me of the recalled items and replaced them promptly free of charge.
Good service with this provider, no hesitations in recommending to anyone.
