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 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!!

Had quotes from several companies from your website. Had actually decided to go with another company but they didn’t get back to us. Goliath came highly recommended. Rang them and it was all sorted that afternoon. Show additional information

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.

From the initial enquiry to installation, Goliath Electrical explained clearly and precisely what was going to happen from start to finish. Very professional & friendly service by all members of the team. Extremely happy with the installation and would certainly recommend them. Show additional information
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.
Got quote one week and installed the following week.
Absolutely the very best customer service including the installers.
Very highly recomend.

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.

The whole experience from the initial call from Tom to installation has been high quality. Excellent communication. Knowledgeable and friendly staff. Quick hassle free install. Highly recommended. Show additional information
I had a call from Tom about 2 hours after requesting a quote. He was friendly, informative, not pushy and sent me a quote with some videos that explained everything. Tom followed up a few times while I waited for other people to give me quotes and do a measure up. I never felt pressured. When Tom came to do a measure up he was far more thorough than the other company and really knew his stuff. Everyone else told me I could get 5kw but he managed to get 6kw on the roof by using bigger panels that they don't usually use but managed to source for us. They just installed my system today (a day early and in the rain). Dave and the boys arrived on time, took about 3 hours to install, cleaned up after themselves, were extremely nice, made sure my dog didn't get out and even put my bins back for me. I cannot speak highly enough of Tom, Dave and the team. I would happily recommend them. Show additional information
Goliath provided us a very keen quote, their installation team was very quick and efficient and their customer support and responsiveness has been exemplary.
A very professional outfit - highly recommended to prospective buyers looking for a quality solar system supply/install.

The whole process was very easy once I had decided to use Goliath. I asked Six companies to come out and give me a quote, one came out looked at the job and never got back to me. The others all turned up with Google or Nearmap photos to quote from but Tom from Goliath was the only one who took the time to get on the roof and actually inspect the Job and give me a few options, this is what sealed the deal for me. The quote was Just above mid range with Fronius and Canadian solar components, they arranged for the meter to be changed on the day of instillation and they arrived on time and I considered them to be very professional in their approach. I would thoroughly recommend them to anyone considering a solar instillation.

Hi Phil,

We really appreciate your feedback, obviously a tricky design with your roof so great to find the correct solution by getting up and measuring the roof upon quoting.

Thanks again from the Goliath Electrical Team and happy savings!

The actual installation (tile roof) was very slick (about 4 hours) and the meter changeover by SA Power Networks happened an hour later. So by 2 o'clock we were connected and job completed.

Tom rang again later that afternoon to check that everything had happened as promised, noted that we were generating at expected capacity given the weather, confirmed that we were able to monitor output with the web app. All done.

Excellent experience all round, including the clear info on your website. Well done all!

Hi Greg,

Service was prompt and painless from start to finish the guys at Goliath made it as easy as possible for us. They found us the best deal, everything was explained to us in easy to understand terms, installation was hassle free and the team were friendly and easy going. Show additional information
We have been shopping around and looking at solar panels for about a year off and on.
On several occasions we had consultants come to the house to have a look and honestly by the end I was tried.
All these wonderful graphs and pay backs.
I know what my power costs and easy enough calculation to work out if I generated X KW per year and X went to the grid, then the saving is retail KW minus what I used plus what entered the grid.
They dazzle you and the maths is floored around their savings predictions against the capital outlay.

Then I meet Goliath Electrical.
OK now this was very different. First of all they are the installers, second they buy without a middle man and thirdly they knew allot of actual relevant details
For example, the system brand, best orientations and the service was very good.
On the day of the install, again brilliant and the owner himself was their doing it – like this.
After service – again brilliant and never an issue with any question I have.
On top of all this, top quality product with a realistic price.

I have recommend them to my family who have taken up their offers to.

Tom called the same day I put the quote request in and was happy to have a long chat with me to answer all my questions.

They did everything they said they would, when they would. Very happy with the service and the end product. They made it a breeze.

Could not speak more highly of Goliath Electrical. Information from Tom Morgan about the different systems and prices etc was the best of the four quotes we got. We chose Goliath because they had so many good reviews and now we can see why. They had the best customer service and installation was quick and easy - no inconvenience. David Stevens had a team helping him who were excellent. They left no mess and were very friendly. Look no further than these guys. Thanks Goliath. Show additional information
One week turnaround from signing up to installation completed.I dont think any one could complain about service like that.Great salesman and both installers very friendly and helpful explaining how everything works.very stressfree experience.Highly recommend the boys from Goliath.

Was hoping that all 3 would get back to me, one didn't, and the other company sales team didn't seem to communicate on who had sent me emails as i got one email from one guy guy then 3-4 days later got the same email from a different one then the first one sent another explaining the second guy didn't know that i'd already been contacted, so I thought if you can't get that right there's no way i'm letting you on my roof.

I did have other quotes not through your site, But Goliath was one of the ones that i did get through your site, very professional, Tom the sales guy kept in touch through out the whole process, my meter is owned by AGL and we are with Origin, so he got all that sorted out for me, we were given an approx date of November 2nd but then Tom contacted me and said 28 July would be the install day as they shut down for couple of weeks around that time, they were here early and installed all 36 panels by just after lunch, we ended up getting a 9.9kW system made up of 36 x 275w Canadian Solar panels (tier 1) and Fronius Primo 8.2kW inverter installed for $8200, David the owner even installed the new clothes line brackets for us as we had a new clothes line but no hammer drill, They where even so impressed on how it turned out they've used a pic of our panels as the cover photo on their Facebook page, as i said in the review i left them on your site I would definitely use them again if i was to buy another house and wouldn't hesitate to recommend them to anyone look at getting solar.

The whole experience was great, from the first phone call all the way to installation day!
Some delays on our side didn't bother Tom and everytime I called or emailed, over several months, he seemed very happy to answer my questions.
Dave and his offsider were efficient, respectful and polite on installation day and ran everything past me before commencing even though I was stuck at work.
Would definitely recommend Goliath to anyone talking about solar if they are after a system with quality equipment, service and workmanship.
Thanks Again!

Dave and his team arrive on time and seemed bright and happy to be here to install my system. They only took 4 hours and left my place clean and tidy. Dave gave me a run down on monitoring the system, logged me in and executed the warranty (10 years). I could see it worker before they left. Very happy with the install and the job and particularly happy with the service, advice and help from Goliath Electrical. I am happy to recommend them and have already done so. Great team.

On Friday I had the guys from Goliath electrical install our 9.9kW system (36 panels i think it was) on Friday 28th July, The guys were promptly here at 7.30 am just like they arranged to be.

Tom did an awesome job sorting out our meter which is owned by AGL and we are with Origin, He also kept me in the loop as to what was happening with the meter the whole time, and answered questions we had no matter how silly they were.

David and the guys did an amazing job on the install, We couldn't be happier with the results, and it only took them around half a day to install.

David even went as far as installing the brackets for our new clothes line (which he didn't have to do) as we don't have have a hammer drill, talk about going above and beyond.

If your looking at getting Solar (or your clothes line brackets installed) give David and the guys a call, Tom really knows his stuff and David the install team do an amazing job.

Thanks again guys you did a awesome Job.

I wouldn't hesitate for a second to recommend these guys to do your solar, if we ever buy another house we'll be back for sure.

I would put pics up but I don't have any sorry. But take my word for it it looks great.

One very happy customer here.

Thanks again.

Hi Glenn,

Thanks for the kind words and giving us the opportunity to install your system. It's great to see the system hitting over the 8kW mark during winter!

Happy solar savings from the Goliath Electrical Team.

Goliath provided the best supporting documentation with their quote (rather than just website links), and were the only company to make a site visit which we found reassuring as it is not a standard installation. System is to be installed in about a week from now. Show additional information
David and his team were very prompt and professional. I was kept always and regularly updated as to the progress towards installation. Installation date was accurate to the minute. Team left no mess and worked hard and efficient, but did not compromise quality. I have 26 X 280 watt Canadian Solar Panels (7.67kW) and Fronius 5kW Inverter and wifi monitor.. It has been a joy to see the power production version grid consumption. So far production has exceeded grid consumption. I use the R/C air conditioning for heating for several ours in the morning, before I am generating any solar but still we are winning. This is winter here now in Adelaide, SA even so I have been seeing power production in excess of 6 kW. I will continue to monitor input/output regularly, but based on my initial results should see and expect fantastic numbers helping management future power needs. In co_operation with GOLIATH Electrical, I will review our power needs after 6 -12 months to see whether battery back up is an economic option, based on then battery prices and our requirements for after hours energy and when there is any future power outages.
