Perth solar testimonials

Jacquie, Mandurah

Quote was the easiest to understand, very straightforward and clear. The boys on the day were very competent and looked very experienced. Left no mess and system is working above quoted numbers. One of the few good trade experiences I have had lately.

I highly recommend Formula Sun for solar power supply and installation
Formula Sun's quote to supply and install solar power offered a range of panel and inverter brands of different qualities and costs. We chose the mid-level option at the lowest cost of four quotes received for comparable products. Thereafter we had to do nothing - the whole system was installed and operating within a week of getting the go ahead. I'm now thinking of getting them to install the same system on a rental property we own. I won't bother seeking competitive quotes.

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 electricity 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.

10/10 would recommend.

Efficient organization
Panels and electrical work completed in one day with a follow up the next day for a Western Power requirement.

Hi Phil,

You and your guys made the whole process easy and painless, for which we thank you.
Will be in touch if needs be, but I’m pr optimistic that that won’t be necessary.

Original Review on 08-10-2020:

Great experience getting solar from Phil Mercer and team.
On time, all well organised.
Fitting crew guys were quick efficient and tidy.
Thanks Formula sun.

8 months later we asked Steve: "Are you happy with the performance of your system so far?"

After nine months since instillation we are very happy with the system.
Saved heaps and love the sems portal app that keeps us informed day by day.

Phil installed the solar system on my house in December 2013. Since then it's performed as expected and has actually increased in production year on year. It's now 10 years old and producing more power than it did in its first year! It has now produced 80MWh.Phil informed of a safety recall of roof mounted isolators and promptly replaced them free of charge with no instigation from myself. I have no reservations in recomending Phil and his team.

Phil and the guys at Formula Sun were very professional, had prompt communication and the best price I found. Very clean install as well. Cheers guys.

Good system Great advice, saved us thousands, showed me the stats on the different inverters so we could make an informed decision. System performs great exactly as presented to us. Easy to understand quote. Quality installers.

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.

Tim, Caversham

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 Inverter rating: 5/5

Gareth, Heathridge

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
