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:
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. Tom kept us informed along the way and followed up with an evening call on the day of installation to check we were happy with everything. I could not fault the whole experience and would not hesitate to recommend Goliath Electrical to family and friends if they were looking to install a solar system. Show additional information

Dealing with both Tom and David was pleasant experience. Tom presented few options and help us to choose the best one for us. We were kept inform regarding all progress.
The installation was done on time, David listened to our concerns and addressed them to our satisfaction. The whole job was done very professionally, they even replaced some cracked roof tiles so we will have no problem in future.

They we great from the start answering questions back and forth to find the best system for my needs. They followed through with all the papper work from changeing the meter to getting the rebate in quick time. They even cleaned up after the install and called to check that the system was working as expected. Good company to deal with. Show additional information
They were on time professional and ensured I was happy.

I would recommend them in a heart beat.

Tom was great at providing all the information up front on our first conversation and providing all the key details almost immediately. He came out to do a measure up to confirm the number of panels they could fit on my roof, he kept me up to date with progress and was very approachable. David and his team arrived on time and had the system installed and up and running very quickly. They helped me understand how the inverter works and set up the app so I can monitor it from my tablet. Tom also rang later in the afternoon to check if I needed any further assistance and how the system was running. I would definitely recommend anyone in SA looking to get solar to go through Goliath Electrical. Show additional information
The system is not installed yet and I would be happy to repeat this survey once it is in and operating. I found the service provided by solarquotes fantastic. Show additional information
Goliath Electrical have been excellent to deal with throughout the entire process. They are very cabable and professional, and kept me informed about all aspects from start to finish. My Fronius system including smart meter has an the intuitive app and web interface and has all the information I want to see about my system's performance. This was all set up for me by Goliath Electrical. So far, the system has only been in place for a few days, and it is performing exactly as expected.

Hi Doug,

Great to hear we have delivered a system up to your expectations. Really appreciate your business and your understanding with allowing David to start the install at the crack of dawn to beat the heat!

Thanks again from the Goliath Electrical team and enjoy the savings!

Our system is 9.8 kW of Jinko panels with Maxim optimisers integrated, and an 8.2 kW Fronius Primo inverter. Also Fronius smart meter.

We were very happy with Goliath Electrical. Tom contacted us within 24 hours of our requesting quotes and was enthusiastic and interested. He was willing to take a lot of time investigating various options for us, and indeed, after we had accepted our quote and paid the deposit, came back with some new options at a significantly cheaper price. (A full $2000 cheaper overall.) Definitely interested in doing the right thing by us!

David, the owner, does all the installs himself so has an obvious interest in doing them correctly. Both he and Tom were pleasant to talk to and happy to discuss all the possibilities.

Overall we think we have a great system, well installed and at a great price! System is already generating 8KW, despite it being 37 degrees outside. Looking forward to getting a battery from Goliath Electrical in a year or so.

Absolutely recommend Goliath Electrical . We are really pleased with our solar system, great team of guys a job well done.. We are now looking forward to cheaper electricity. Show additional information
Goliath were brilliant to work with from start to finish, from planning the system and quoting to installation during difficult weather conditions. Being a small business, planning, quoting and installation are all done by the same small team, not a random contractor. Despite being a small company, they proved very capable of installing a large system. The only minor blemish was a miscommunication that has delayed the installation of a smart meter.

Hi Dan,

Again thanks for the kind words, was a pleasure to work and design a system for your situation. Trust you're happy now with the smart meter after the small hiccup and ability to monitor the consumption and production.

Thanks again from the Goliath Electrical Team

Both Goliath and Solar wholesalers stood out as good options with similar pricing for quality systems. The installation has been delayed due to christmas/new year slowdowns with SA power networks. Great communication from Tom at Goliath who was very happy to share his knowledge and help me come up with the best option for me with no obvious hard sell. In contrast to the hard sell from some other companies (who were not referred by Solar Quotes). Installation due in a month....hopefully it will all continue to go well.

Tom and David did a first class job with the install. Prompt and responsive service leading up to the install. Issues with SAPN aside, we're very happy with the result. Show additional information
A great all round experience. Quoted for a premium system that was expertly installed with clear explanations of how to best utilise the system. Show additional information
How easy was that! These guys are Amazing! Can’t praise them enough!
Tom Morgan did the quote without any hassles of any kind – straight forward.
Explained it concisely and gave a quote on the phone– really knew his stuff. Then
Came out, got up on the roof, quoted the same price for an even better configuration.
He then juggled the job-diary to suit our prefered date (before we went on holidays) and it was all done efficently as promised. David (the owner of Goliath) does the job himself with the help of a very competant offsider. They even grind a groove under the roof tiles so the brackets go through without pushing the tiles up. Tom even wants to give advice after we get our first electricity bill re the types of supplier-contracts to suit our useage.
Highly recommended!

Thanks again,

We had our Solar system installed during November. We chose Goliath Electrical to be the supplier / installer, as they were extremely helpful in supplying any information we requested. They were very prompt with their site inspection and quotation. Installation was completed on the set date. All completed in the one day. Everything is working well and achieving the results we were expecting. Found Tom and David to be very nice guys and easy to deal with. Left the site spotless. We highly recommend Goliath Electrical.

It all went very smoothly. Only the connection to the grid by the authorities is outstanding and that waiting time downgraded the experience. Show additional information
Great to deal with, very organized. Installation was done before lunch, followed up in a couple of days after installation. Can't speak highly enough of the team. Show additional information
We were very impressed with Goliath. Tom the salesman was extremely helpful, listening carefully to our situation and suggesting possible solutions. After we had chosen one with his help, he kept us updated on the installation plan. Installation was performed quickly and courteously on the planned day, and in the couple of weeks since we have had no problems with the system. Show additional information

Goliath were first to contact me and gave me great assistance as we progressed. All the quotes and systems offered were very close but their reps just seemed to go that extra step and made me feel comfortable about their offers and workmanship. I have been reserved in my ratings about value and quality only because I don't know enough about the industry. Show additional information
We have not had the system installed as yet, we have paid the deposit and are still waiting for them to measure up. Not good service so far, was very friendly and couldn't do enough for us until we signed on the dotted line and paid money, since then the communication has pretty much ceased.
Hopefully their installation service will be better??

The service given by Goliath Electrical was efficient and quick. The solar system was installed and up and running within a month from the quote. The installation team were excellent taking only half a day to install the system. We were very happy with the system and service. Show additional information
Very friendly, low pressure sales pitch. Willing to answer questions in a friendly manner and cater for my opinions and requests. 3 month on, system of Canadian Solar panels and Fronius inverter functioning well, routinely attaining 3kW production. Inverter installed neatly. Had other electrical work done on the day, also to a high standard. Show additional information

I had my system installed yesterday and thanks to Solar Quotes for the best information source on solar on the net, I found this website very informative and easy to read and understand. I had 3 quotes done, all recommendations from Solar Quotes and found a very large difference in these quotes even though they were all supplying very similar systems both in quality and performance. The company I chose was very informative and the product information was outstanding AND not pushing to get a sale. They gave me the cheapest quote by far for a quality system, which rates high on the Solar Quotes website. (Fronius Inverter and Canadian Solar Panels) The installation was performed with no fuss, no mess and no inconvenience to myself or my family and I found the installers to be very polite and knowledgeable on both product and installation procedures. Thanks again to Finn and his website, great job. Show additional information
Great service and top notch installation. Very easy to talk to, and accomodating with the many questions I had regarding the system.

Will use them again.

The Installers Polite and Friendly. Brilliant quote.... I am very happy with the outcome... Show additional information
The whole installation was very smooth, Tom and David had organised everything, our 3 phase power service point had to be relocated which they arranged. That work along with the new import/export power meter was also carried out on the same day as the panel and inverter install. All up, a very good job and I am very happy. Show additional information
Extremely friendly and professional service. Will definitely use them again for a planned future expansion. Show additional information

Small company that provided very contact and quotes in first instance & then did a great job at installation. No fuss at all. Helped out with SA Power Networks booking which came together well. Show additional information
Great communication throughout the process and a fantastic system installed.

Dave, the owner & installer even came out at 9pm to get our hot water working because one of the wires in the meter box didn't connect properly when SAPN installed the new feed-in meter.

I recently had Solar Panels installed and would like to thank the guys for their professional attitude towards their work and their very friendly nature. They informed me of what they were doing every step of the way. The guys got to my Unit ahead of time which freed me up for the day which I really appreciated. I highly recommend the lads at Goliath and it was an absolute pleasure dealing with them. Show additional information

Your service is invaluable there is just too much information out there to go it alone, as for Goliath Electrical Tom there business manager kept me up to date every step of the way and was even out at the house pitching in on install day. Dave the company owner also the installer so he understands its his reputation on the line more then happy with there efforts to the point where i hope to get Dave to do some other electrical work at my property.

I'm an electrician by trade, David and Tom allowed my input on placement of 2 arrays and placement of inverter, good quality install.
Goliath Electrical were the only company out of three quotes who rang back and gave good technical advice, as I had done quite a lot of research on Enphase and Solaredge.
Solaredge I feel is a superior product with optimisers allowing maximum individual panel output. Especially when there are different strings with PV arrays at different angles to the sun.
Solaredge website has all information to monitor system and is free usage. Also rang Solaredge support and given good advice / information from Melbourne call centre.
Had TV RF problems due to antenna being to close to array and poor signal strength in Athelstone, Goliath Electrical and Solaredge organised and had new antenna installed.
RF problems solved. TV signal okay.
Solar Quotes website has been a good source of information very useful.
