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:
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.

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!
Show additional information
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!

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. Show additional information
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.

Very helpful and accommodating. Good at communicating what they are doing and answering any queries. They worked quickly and efficiently and explained the system in a way that I could understand. Exceptionally good customer service. I have a disability and I would highly recommend them for people such as my self or for older customers Show additional information
Tom Morgan is the real deal. No bull just honest straight advice and the follow up has been spot on. The system is yet to be installed but judging by the experience so far I have no doubt it willl be smooth sailing. Show additional information

Tom's help and advice with sizing and speccing the system was excellent, he clearly has a passion for his job and it shows. We made a few changes to the spec through the process but we stayed within our budget and ended up with a much better system than we were expecting.

David and Thaelan did a great job with our install on a tricky roof, it looks good with all the installation neat, tidy and professional, they too are clearly passionate about what they do and it's clear they give a sh!t about doing a good job and getting a good result for their customers.

I wouldn't hesitate to recommend them to anyone.

All in all I'm happy with the outcome so far, we just need some sun to see how the system itself performs!!

Goliath were punctual, professional and efficient. They did the installation cleanly with minimal disruption. Show additional information
Should I have received a statement of electrical compliance?

Nothing else to say until SAPN connect the system to my powerbox tomorrow and the system is actually going.


Thanks for your excellent service, Finn and Solarquotes. It gave me huge comfort to know I had access to accurate information and calculators.

We've had a fantastic experience so far - Tom followed up some questions that we had and dealt with the placement of panels being made tricky by some antennas. System hasn't been installed yet, but the service and communication has been top-notch so far. Show additional information
Great experience through both the sales and installation cycles. Technical expertise during sales was very much appreciated. Installation lead time from sales to instal was less than three weeks. Highly recommend Tom and David for solar. Show additional information
We had Goliath install a 4kW+ system in our city townhouse.

From the start we were confident with Goliath. Tom who does the initial assessments was very knowledgeable and readily available to answer all of our questions. Their competitors only seemed to want to only offer the easiest solution from them to install and not what was best for us. Tom was very good at listening to our needs and producing a system that would work for us.

Pricing wise we were very happy, Goliath was very competitive with the other top rated installers but for us their competitive difference was being a small Adelaide based company with direct communication to the owner. We love supporting local businesses and Goliath was excellent with no trade offs in quality.

We also really liked that David, the owner, was the one doing the install. Some of the bigger groups use sub contractors which didn't sit well with us. David and all of his staff were conscientious, considerate and professional. We have a young baby and all of the staff made an effort to work around our family. They cleaned after themselves, worked really quickly and were always friendly. Our install was a little more challenging then most as it's a 3 story townhouse, this made cabling a challenge. Not once did the Goliath staff complain.

Overall they;
Had clear communication, no over the top marketing hype
Were competitive on price
Used quality staff and materials
Kept to their quote with no hidden costs or surprises

We would thoroughly recommend Goliath for your Solar install.

We were very happy with the whole process with Goliath Electrical. From the first phone call through to installation, follow up. We are more than happy to recommend these people. They gave us all the checks and info we needed regards their panels, inverter we chose. They have great attention to all the details, kept us in communication, just did it all so well, from start to clean up and as we said ongoing support. Very happy! Show additional information
Went with Goliath Electrical and everything has worked out well. Right from the start Tom was helpful and informative which gave me confidence straight away. they use only the best Panels and Inverters. Tom organised everything with AGL and SA Power Networks and kept me informed on what was happening and when it was to happen.
David and his boys did the installation which was done on time and very professionally. At "Switch On" things did not go according to plan, the system kept giving error messages.
It turned out this was caused by a faulty wire bringing power into the property and nothing to do with the new solar system. David contacted Fronius for information etc., worked out what was happening and contacted SA Power Networks to send a line person out to check out their part of the power network. Their worker worked out I needed some new wiring from the stobie pole to my house so he brought in another team. I was very impressed with SA Power Networks quick response and they soon had everything working as it should. David did not leave the site until all was working properly ( several hours after the actual installation was completed) and Tom is calling around tomorrow to make sure all is still working OK and to make any minor adjustments if required.
All in all could not be happier and would highly recommend Goliath Electrical to anyone wanting a Solar System for their house.

Hi Bill,

Again thanks for choosing Goliath Electrical and the kind words. Obviously little bit of a curve ball with SAPN issue but great to see some positivie feedback regarding SAPN considering the bad press they have been receiving lately. Glad we could have the issues resolved so promptly and have you saving straight away!

Thanks again from the Goliath Electrical Team

Tom and David work as a great team and are both excellent to deal with They are professional, organised, friendly, and happy to answer any question along the way.

Tom from Goliath was very helpful leading up to and since installation--nothing was too much trouble and he always returned phone calls and emails promptly.

As far as installation goes, David and his team were on time and completed the job in the timeframe originally discussed.

The system is working well and it is good to be able to monitor input and other data on our desktop computer.

I spoke with a few companies both via this website and not, as soon as I spoke with Tom at Goliath you knew he is a genuine guy. That along with their best pricing up front for a quality system I knew I would go with Goliath. There was no "tell me what price you got and I'll beat it" speech, Goliath gave the best price up front!
Tom was extremely easy and pleasant to deal with, with constant updates along the way. Dave ( the owner ) came out to fit the system with his guys, all extremely friendly and did a fantastic job and left with no mess for me to clean up, and great to have the owner hands on fitting the system. We ran into one little hick up with the meter change over but Tom was allover this like a rash, within the week he had sorted the issue and had the meter changed and system up and running. His follow up was nothing but fantastic and apologetic for the small delay.
I would 110% recommend Goliath to supply your PV system, the friendly service, quality work, great communication and great price for quality gear make it too easy to do so.
Thanks go to the team at Goliath Electrical.

What can I say, Goliath Electrical were fantastic. Very prompt, honest and great at explaining solar power in full detail to someone who had a very little knowledge on solar energy. I contacted Tom over the weekend expecting a response back on the Monday but Tom came back almost straight away and answered all my new questions that I had. The installation was done with absolutely no fuss and I look forward to receiving my first power bill (a weird concept, I know right?). You won't be disappointed with Goliath Electrical, they will look after you the whole way. Show additional information
From start to finish the Goliath team were excellent. From the initial appointment to the day of system installation they were always on time. Dave and his boys installing the system were very friendly and had the install done in no time, in a really efficient manner.
