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:
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.

Goliath Electrical to me was by far the best company if you are looking to install a solar system. I was really impressed with Tom's service. He is professional, patience and very prompt in reply and answering to the many questions I have regarding solar system. He is also very knowledgeable and was therefore able to recommend the best system based on my needs. I am also very happy with the installation which is done by Dave and his team for their thoughtful recommendation to position the panels to ensure best functionality and look. After installation, they took the time to explain how to read the inverter, meter, set my mobile and everything in between to ensure the system works and I was able to see on my mobile phone the energy output. It's amazing really. I would recommend Goliath Electrical anytime to my friends and family who are looking to install solar system. Show additional information
Having worked in the solar industry I was a fussier than normal customer. I also have a roof with shading and orientation issues so they were able to ensure I had a system design that was best suited for my site. I have no hesitation to recommend Tom and the crew at Goliath to install your solar system. Show additional information
We were recommended to Goliath by a mutual friend and we were not disappointed. Tom from Goliath was extremely attentive and not at all pushy. He gave us the options available but did not push the higher priced solar system. He was always contactable and would get back to us immediately if we had questions. Being close to Christmas we didn't expect to have our installation but he was able to fit us in. The installers were excellent also. We made an additional request to move our aerial and both Tom and his installer Thaelan did not see this as a problem which was a relief so we're very happy customers. We were very conscious about not having the solar panels be seen from the front of the house and they more than achieved this. If anyone wants solar we would not hesitate to recommend Goliath and Tom. Show additional information
Everything with this mob was first class and well done. Tom, the salesman, was very helpful and knowledgeable and was always contactable with any questions I had. He was the only sales guy who came out & climbed up onto the roof to have a look and measure. The guys who installed the system, led by Thaelan, were very professional and got the job done quickly in the 37c heat. The system seems to be functioning very well - very happy.

Hi Greg,

Really appreciate the kind feedback and so glad to hear you're happy with the system installed! Glad we also managed to keep the panels away from street view as per request. All the best with the new system from the Goliath Electrical Install Team!

My solar experience of the full selling and installation process with Goliath Electrical was faultless.
Not the cheapest but good value with quality components and proffessional from start to finish.
The installation was a two storey site and in my view tricky to access but they worked safely and efficiently without incident.
I have recommended them and will continue to recommend Goliath.

I received a call back from Tom within 30 minutes of requesting a quote. From this moment every aspect of our system, from recommended system to install, to installation itself was handled professionally and smoothly. Tom visited our house to see for himself the site and do a pre measure up. Tom clearly explained his recommendation with no pressure and promptly responded to my additional questions over the following few days while I considered alternatives. I was interested in installing the largest system possible on my roof, and could have gone slightly larger, with a higher capacity inverter, but Tom thought that the gains from the added capacity were not enough to warrant the added expense. (If this was a test of integrity - and it wasn't - Tom would have passed it with flying colours!) In the end we went with his recommendation and now after a month of the system in operation are very pleased that we did - the system is performing very nicely.

Tom did all the paperwork & contacts with the authorities and our electricity supplier and saved us the trouble of doing it ourselves. It all happened in an efficient manner.

On installation day, Dave and his team turned up on time and cheerily went about their work in a pleasant & friendly manner even though it was the second system installed that day. Dave happily answered other questions I had as the installation took place. They were finished in no time and cleaned up before they left.

To sum up, every aspect of the process was handled professionally. I have no hesitation in recommending Goliath Electrical as installers of PV systems.

We had a 6.6kw of Canadian solar panels and a Fronius inverter Golliath electrical were an absolute pleasure to do business with, fantastic customer service and a great job. Show additional information
I installed a 6.6kw East/West system with a 5kw Fronius Primo Inverter in the Adelaide Hills. After a full day of sunshine yesterday the system clipped at max for only a couple of hours with a total yield of 41kwh– a great result. I am very happy with the system and the install. Great customer service and seemingly a down-to-earth and genuine company. The install was problematic in that there was too much drizzle to safely install the system on the install day, but the boys ran cabling and were able to reschedule the job and came out on the Saturday to finish it off. I would definitely recommend Goliath Electrical to others looking to do a solar install– nothing was too hard for these guys. Show additional information

Goliath Electrical were great. They didn't try to hard sell anything but really talked through the options ad gave me plenty of time to think things through and decide what i really needed. They were genuinely interested in my needs and expectations and gave me excellent advice during the on-site inspection. Gave me a very fair quote which i checked against other suppliers and offered excellent components/brands. The installation was excellent - they took a lot of trouble to ensure they didn't damage the tile roof when installing the array and spent quite a bit of time checking from inside the ceiling cavity and the outside roof after installation to ensure there would be no problems - even spent extra time to silicon as a precaution any possible problem areas. I was really happy with their entire approach - very professional and tuned-in. Thanks Goliath Electrical!!

It's no accident that Goliath are among the highest rated companies on this website.

Let's start with Tom. Tom is the reason I decided to go with Goliath. His friendly, no BS approach to sales (and he is a salesman) is a breath of fresh air, in any industry. I had questions answered that I didn't know I had. The entire process, both from his end, and those of other agencies, was clearly laid out. A site visit, and indicative layout were part of the service. Tom contacted me via various methods at every stage of the process. Well done Tom!

The installers were punctual, friendly, knowledgeable, and they cleaned up after they left. They double checked with me regarding the location of panel array, and inverter. They configured the system fully, and explained operation of it to me before they left. Good job boys!

I would have no hesitation in recommending Goliath Electrical for the supply and installation of your solar system.

Goliath Electrical were prompt in following up the quote request and were extremely helpful in tailoring a system to my needs (addition to an existing system), particularly discussing system performance expectations related to my roof aspect. Always followed up as promised, punctual, friendly and efficient. Service was first class, would definitely recommend. Show additional information
Having spoken with many sales people during this process I was most impressed by Tom's no BS approach. Did not treat me like a fool and gave what I thought was very good advice. Installation was completed in a timely fashion and system was up and running immediately. Would not hesitate to recommend Goliath Electrical to anyone considering a solar installation.

From the first phone call, this has been the best customer experience I have had in many years.

Tom was incredibly helpful, explored loads of options and at no time tried to "oversell". He arranged SA Power networks, sorted dates etc. Installation was a top job - great blokes who paid real attention to detail and neatness.

Everything has worked exactly as I had hoped. I would absolutely not hesitate to recommend Goliath Electrical. Thanks a ton.

The guys at Goliath managed to get the whole system installed in half a day on the day we had arranged on initial agreement. It's all they do. They are experts and can advise you in a practical and economical sense. Now we have an awesome set up. Thanks Tom & Dave! Show additional information
Goliath Electrical recently installed a 4kW solar system at my house. I found them:
- Professional
- Very helpful in answering my many questions
- Realistic in the output I would get from the solar system
- Responded quickly to my phone calls
- Prompt in fixing a problem (which turned out not to be their issue but a supply problem)
- Provide a good quality installation
- Friendly and courteous
I would not hesitate to recommend Goliath Electrical to anyone.

Hi Jon,

Thanks again for choosing Goliath Electrical and the positive feedback. Also really appreciate your patience with the network issue with over voltage supply and happy to help resolve the issue.

Many thanks from the Goliath Electrical Install Team

The transparency of the whole process from sorting on your website, what mattered, payback period with calculations to back it up, who & what brands were reputable etc. was the clincher for me. Previously I didn't understand how it worked especially with a big air-conditioner and I had stories of 20+ years payback. Goliath were very careful in every aspect and finished a day ahead of original plans Show additional information

After receiving quotes from 4 different companies, I decided to go with Goliath Electrical.
They were not the cheapest but after doing a great deal of research online, the system they offered was certainly what I was looking for.
They also provided the best customer service with prompt quoting and answering of questions
After receiving the quote, Tom made a time to visit my home and discuss the system and explain fully what would be involved.
Up to the installation, Tom made sure he was in touch regularly and installation appears to have been done very professionally.
I feel very confident that should an issue arise I can contact Tom and he will happily advise and answer any queries.

Tom from Goliath was an excellent introduction to the company. Nothing was too hard and no time was wasted producing their quote then modifying it as our system evolved. The installation takes place in a week but I am confident we will get a quality install and follow up customer service if we require it. Quality system, quality guys, realistic price = happy customer Show additional information
Tom from Goliath has been great right from the beginning. He explained every step and told us all costs , leaving nothing out.

Happy to recommend Goliath Electrical, friendly, great to deal with, they arrived when they said they would....highly recommend Show additional information
Tom from Goliath came out to see the site and advised us on the best system to suit our needs. When we decided to proceed with the installation of the solar system he explained to us that the system would be installed on the same day that SA Power networks were fitting the new meter, He came again on a later date to set up our wifi and he said that he would be able to monitor the system remotely. The fellows that came out to do the install were very courteous and after they had finished they made sure that the site was left clean & tidy. All in all it was a pleasant experience and we would not hesitate to recommend them to any person looking to install solar power. As a matter of fact our son is going to have solar power on his new house and he has already been in contact with Goliath Electrical.
