Goliath Electrical 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:

Tom from Goliath Electrical was great, explained what i needed to know specifically micro-inverters vs power optimisers and standard install. Signed up both my sister and I. Gave a good price and communicated well through out the whole process. Would highly recommend them. Show additional information
The whole process from start to finish took about 12 months however, as a result, we ended up with a better financial outcome and a slightly larger system. Installation wait time was less than a week, installers were punctual and extremely polite. Show additional information

Fantastic experience. Tom was all over it - from the time we requested a quote through to post installation follow ups. Tom was very knowledgeable, and answered all my many questions thoroughly, and with an unbiased view. Installation itself was well ahead of schedule, and we had our solar up and running within a couple of weeks of progressing the quote. Installation was very professional and the crew cleaned up the site to expectations. We were aware we were not getting the cheapest system, but ultimately very happy with the value for money for the system and service we received.

Overall I couldn't speak more highly of Goliath and the experience we had.

All went smoothly and am very happy with the result. Glad I went for a system that generates more than we need, as real-world use shows we are not getting the full 5kW system (there's an article about that on the SQ website about that) - so keep that in mind before placing your order.

Overall, I'm just impressed that I can leave for work one day, come home and I'm on solar power.

The installation from Goliath was really well done and was a happy with the level of information/salesmanship shown by Tom.
Not too pushy, but enough to keep the ball rolling. I appreciate he has a job to do and I wasn't put under pressure to sign on the line.

Goliath Electrical were extremely professional and efficient from the first contact to the last. Tom explained everything clearly and provided several options for our consideration, along with all the technical detail we desired. The installation was flawless, and the installation team were on time, polite, professional and ensured the site was clean and tidy at completion. Tom followed up after installation to ensure everything was to our satisfaction, and maintained contact until our meter was changed by the electricity provider. I would recommend Goliath Electrical to anyone looking to have a solar system installed. Outstanding service at every level. Show additional information
Fantastic company!! Tom was friendly and helpful throughout the whole process, didn’t have to do anything as he handled it all. They were the only company to get on my roof out of the 4 quotes to measure and inspect. Installation guys were helpful and cleaned up after themselves. Highly recommend to anyone looking to install solar. Show additional information
Tom Morgan is an excellent rep of your company. He thoroughly explored issues related to installing above bull-nose veranda,(eventually not proceeded with), inspected first hand options available on flat part of the roof (unlike a previous quote) and followed through with all aspects of the installation Show additional information
Thank you. We received 3 quotes within a week of our enquiry. We were to be able to get a new system installed within 2 weeks of receiving our quotes so we could start using less power from the grid sooner rather than later. We found the information on the solarquotes website very useful. We are very happy with our system which is a 5 kW fronius inverter and 23 canadian solar panels. On sunny days we have generated 40kWh even in March. We have also been able to tailor our power usage more by using our fronius smart meter which gives a real time power production readout.
Thanks for the useful website

I don't think you will see them advertised. Word of mouth is all they need, because the price, quality and workmanship to us was second to none. WE had 5 quotes Goliath was the first. We came back to them. If you wan't solar go with Goliath Electrical. Well done guys and thanks and thanks Tom. Show additional information
Get your 3 or so Quotes but make sure that Goliath Electrical is on that list (for the South Australians of course). The service, installation and entire experience has been a pleasure.

Hi Nick,

Really appreciate the kind words and appreciate the business. Great to hear the positive feedback and we are just happy as a team we managed to get such a great looking panel design for yourself. Let's hope AGL come through with the goods on time! All the best with the new system from the Goliath Electrical Install Team!

Cheers again

I was referred to the team at Goliath Solar by a family member who had a %kw system installed just under a year ago. I sent an enquiry via their website after doing some research and received an almost instant call back from Tom Morgan, Head of Solar and Storage Division. Tom took the time to explain everything I needed to know about the system including warranty details, panel and inverter types and the procedures surrounding the installation and approval of solar panels. I locked in my panels that day!

Tom took care of all the appropriate paperwork, completing and forwarding it to my provider on my behalf. It was a completely stress-free experience.

After receiving confirmation of my meter change from my provider I contacted Tom and provided the date (7 days ahead). Tom was completely obliging in having the team out on the same day to install the system at the same time. Turns out there was another opening and the system was installed a day early.

On install day, the team arrived right on time at 7:30am as booked and were very polite and friendly. Thaelen and his crew worked tirelessly all day, cleaning up after themselves as they went, working to the highest standards. Thaelen even went to the extra effort to run conduit down the internals of my Hebel exterior wall for aesthetic purposes (and also keeps the missus happy) as opposed to running on the exterior wall. It may have taken an extra 45 minutes work to feed it down and fish it out of the wall but customer service like this exemplified the Goliath experience, going above and beyond to make my investment operate and appear faultless.

I cannot speak highly enough of the team at Goliath. Their customer service is exemplary, their workmanship was second to none and above all, their price was fantastic. Highly recommend these guys as the best installers in SA!

Had an issue with both the meter board and SA Power networks for upgrading the meter. Both of these issues were resolved today (same day) through Dave and Tom from Goliath's efforts. Huge THANKYOU to the installation team - panels look great and installed as per plan - cleaned up their mess before they left too!
Highly recommend - a thoroughly professional outfit!

I was referred to Goliath Energy by a family member and from the first conversation with Tom, was convinced that these guys knew what they were doing. Not being all that knowledgeable about Solar (I knew nothing), Tom answered all my questions and gave me great clarity about what I was getting into.

Tom provided me with a firm quote within an hour of our first phone call and I had the system installed in less than a month from the quote - now just waiting on my retailer to swap out the meter.

The installers turned up right on time, and represented the company impeccably. They were prompt, unobtrusive, efficient and personable - they even cleaned out the gutter which I hadn't touched in 8 years!

Perfect service and a great product. I wouldn't hesitate to recommend to anyone.

One was better on price but salesman was arrogant.

Goliath insisted on home inspection prior to quoting and listens to my requirements better, offering a solution that met my needs well.

You should not use the adjective FANTASTIC-after all it does mean something that is a fantasy and I hope our solar system exists, .Would be better to use real words like VERY GOOD OR EXCELLENT. If you had used real words , the report may well have been higher.
The Goliath people were very good and who could ever forget Tom with his twinkle toes, ballet type shoes and extended tape measure almost dancing across the roof tiles.

Prompt, single contact service from Tom of Goliath. Concise, commonsense explanations and action for all technical, installation, ongoing operational requirements, STCs, warranties, grid meter adjustments with local power supplier and simple paperless invoicing and payment matters. No oversizing/overselling. Only one of 3 quoters that took time to climb up and inspect roof prior to quote. Installers turned up on time in the morning, installed system then patiently helped us install the inverter remote monitoring app on our computer and were finished after cleaning up properly early afternoon. Tom has followed up with remote monitoring to assure that system producing as specified. Took a genuine interest in the system working properly and reckon they will be there to help if we have any problems or need service or upgrades in the future. Highly recommended.

From our first chat on the phone Tom was knowledgeable and answered all my questions regarding how the process would work with system sizing and some of the finer details of the installation.
The price was competitive with all the options laid out clear to understand.
Tom came out for a look at my house and advised reasons for certain details like panel orientation.
Tom communicated well leading up to the installation date.
The installers were on time, courteous and did a great job, explaining any differences between what was agreed with Tom and why.
They sealed up penetrations and tidied up at the end. They were helpful in setting up solar web too.
A great experience and I wouldn’t hesitate to recommend Goliath Electrical.

What a professional outfit Goliath Electrical are, from the first time I spoke to Tom (sales) I knew that he really knew his stuff in the solar industry. I have been an electrical engineer in the buildings industry for 15 years whereby part of my role is to specify solar systems for government projects as well as inspect electrical installations for compliance, quality and workmanship, therefore I threw some pretty hard hitting questions at Tom and he answered them all with clear precise answers. When Sam and his team arrived to do the installation, he ran through everything before starting (again I grilled them with questions!). The boys installed everything perfectly and neatly. They even cleaned up after themselves. I was also surprised about the quality of electrical accessories being used for the install, they used all products that I see daily on large scale commercial projects. I simply cannot fault these guys. Show additional information
Absolutely excellent service, quality and support.
I have and will continue to recommend Goliath Electrical as a top installer of solar in SA.
Keep up the good work guys.

I have no hesitation in giving Goliath Electrical a 5 star rating. Very professional company with friendly staff and I was kept up to date at every stage. All paperwork was handled quickly and efficiently. The first contact person is Tom who knows his product very well and can answer any queries in a very friendly manner that puts you at ease. The installation went like clockwork with the crew knowing exactly what needed to be done. The only holdup is the time it takes for the relevant energy company to undertake the necessary meter box work so the system can start working. This is not the fault of Goliath Electrical as this work was requested at the very start of the whole process.

Thank you Tom and the team at Goliath Electrical - job extremely well done!!

The name of the installer chosen was from a list on your website . Read all the reviews . Asked all the questions . It came down to a toss up between Goliath and another . Both were very impressive . Chose Goliath for the best price installing the EXACT same system.
Very happy with all aspects of Goliath's installation . Communication was excellent .System is performing very well .

One did not contact me at all.
The other provided a good price but did not seem to be a hands on type of company .

Tom was very easy to deal with. He stayed in touch via email and phone, returned calls and ensured that I was happy at all times, he didn’t mind going over things several times and answered all of my questions. On the day of the installation Thaelan and Auden were very organised and extremely courteous. Overall a very easy experience and I would thoroughly recommend Goliath Electrical.

From the first phone call I knew Goliath Electrical was the company to go with for our solar installation on our new terrace build. I work in retail so know how important proper service and advice is to a customer, and Tom was very friendly and extremely knowledgeable and helpful from the get-go. The Solar Quotes website initially helped narrow our choice down and had plenty of great information, so when I began talking with Tom it was easy to understand what we required and a best solution for price also. Our system has been running since install four days ago and I'm very impressed with the Fronius inverter and Canadian Solar 280W panels and what it's pumping out! But what was so impressive with Goliath was their problem solving abilities (especially on installation day due to a major cabling issue!) and constant communication throughout the whole process as our build went along. If you want the best service and advice, don't look past Goliath! You guys are an asset to the Adelaide Solar Industry! Show additional information

When you look up customer service in a dictionary, you'll find it just says "Goliath Electrical". I can't rate these guys highly enough! From the time I submitted my request to the Solar Quotes website Tom and the team at Goliath have provided fantastic service and product. Our installation went smoothly, and the results are amazing.

From the time Tom Morgan called me, gave an initial quote then made a site visit, and the follow through prior to and after installation the service was first rate.

The installation team did their job well and cleaned afterwards.
