We are very happy with our solar panel installation so far. We have only had it for about two weeks, but it is working really well and making a great amount of kWh’s worth of power, especially with having minimal sunshine due to winter. We are really happy with Goliath Electrical, they were great to deal with, very professional and did a fantastic job of installing the system. Ben was my contact at Goliath and he was professional and informative without being pushy. He called me before emailing the quote and he was happy to answer my many questions as solar was all quite new to me! He returned my calls and emails promptly, made sure all the paperwork was completed and sent off, organised for a smart meter to be installed, he really did make the process very easy. I wouldn’t hesitate to recommend Goliath Electrical if you are thinking about going solar. Show additional information

I came into purchasing a solar system as a basic novice. I just knew it was time to do something. And, although all the suppliers who quoted were helpful, Tom at Goliath was miles ahead in practical knowledge, stellar customer service, professionalism and most of all - patience. He has been amazing throughout the process by answering all my questions and anticipating our needs - from beginning to end. He was genuinely interested in getting us satisfied with a solar system that truly matched our needs and budget - not just selling us something to fill an order book. He explained what would happen step-by-step - including having a super installation team. The big day unfolded as he said it would. I can't say he arranged the weather, but it was good too! The installation team was friendly, timely, efficient and left a clean site. What else can you ask for!

I can highly recommend Goliath, Tom and his team, they all made it all look easy.

A big thank you to the team at Goliath especially Tom and the installers (sorry I can’t remember your names).

Couldn’t be happier right from the outset, nothing was too much trouble despite numerous changes and very responsive to any queries along the way.

Only too happy to use them again or recommend them.

Not much else can I say has been a pleasure dealing with you.

Ben from Goliath understood what I wanted out of a PV system from the very beginning and he gave me a very competitive quote. Just over 6 weeks later I have a Fronius inverter on my wall and 6.555kW of panels on my north facing roof. I included the smart meter because I love gadgets, and I really appreciate knowing exactly where my energy is going at all times.
I could not be more happy with every part of the process. Ben was very friendly and knowledgeable, while the installers were also friendly and very efficient. The system is working even better than I had imagined, even today on a showery late autumn day!
I would wholeheartedly recommend Goliath to anyone in Adelaide contemplating a solar system.

After going through multiple quotes, I decided to use Goliath.
They were not the cheapest, but had great installation reviews, and Tom was one of the only sales people to actually come out and get on the roof.
And sometimes after doing all your homework, you have to just go with your gut feel.
Installation went smoothly and system seems to be working as it should.
Can't wait until summer to see how the numbers stack up.

Tom from Goliath gave us our fastest and most competitive quote and was able to answer all our solar questions in a friendly and professional manner. He provided assistance for us with our energy retailer to organise meter change over and an installation date. The installers were punctual and worked hard all day to install our system even with our vaulted ceiling which made installation more difficult. We really like the solar edge monitoring which shows the solar production and our energy use. We look forward to seeing the solar production improve when we finally have some sunny weather!

They left a fair bit of rubbish (small wrappings etc.) behind. Show additional information
We have ordered our system but it is yet to be installed. So am unable to comment on installation and customer service.

This was a large and important purchase for us, so it was comforting to have the reputation of your site ‘on our side’. All three companies were represented well, with good communication and a lack of pressure-selling.

The next hurdle for Goliath will be the installation. At this stageI have no reason to be other than confident that will be OK as well.

The communications and advice from david was invaluable. The installer was a great bloke who went out of his way to accommodate my 10 week old labradors safety ensuring he didnt escape . Thanks Goliath extremely happy customer here . Michael Polson Show additional information
Right from Ben's first contact I found Goliath Electrical and their whole team's approach to be accommodating, friendly, knowledgeable, prompt and punctual.
Once I had reviewed the product they were offering I was completely at ease with the whole process from start to finish.
They were familiar with the system of dealing with Power companies and it all went as they predicted and in the time frame they indicated.
I was astounded with the efficiency of the installation on the day. Their install crew was professional and friendly.
System was up and running way quicker than I thought possible and to this point has not missed a beat.
The online monitoring is working well and there is enough data there to interrogate and choose the best power deal going forward and also to be able to review at a future date and change supplier if need be.
I would recommend Goliath to anyone.

Supplier is also the installer so we are confident of product operation and support. Sales person did not oversell system or its performance.

Ben from Goliath Electrical was not only knowledgable (as were the other installers quoting) but came up with his best price first. He was also flexible with installation and including extra's where he could. In short great service! Show additional information
I was someone who had zero interest in Solar systems until our last bill. We did not do this for any other reason than to reduce our bills.
Your website was a great starting point for my research. (I research everything before I buy)
We have had the system running (for testing purposes) and it runs our house easily. It even covers our 6HP reverse cycle AC if we are producing 6kW.
We chose to go with Goliath as they answered all of my questions and gave me a lot more advice.
The reasons to not put them on my shed roof but east/west on the house in case we choose a battery option down the track.
The original recommendation was to use REC panels but REC took approx 7 weeks to reply to my email which was sent after the un-returned phone call.
We then chose to go with Sunpower panels they are black, look much better and have a better warranty. The increased cost will still see a ROI it will just take a little longer.
The installers work for Goliath, not sub contractors.
The installers were friendly and easy to get on with.
The outcome is neat and tidy. (At least as good as it gets for having panels on your roof...)
Will be looking forward to see what our bills look like over the next 12 months
Highly recommend the people at Goliath

We sought three quotes for our 5/6.6 KW solar PV system, one through local word of mouth and two through Finn Peacock's Solarquotes website. One of those just sent us some literature, and Goliath quoted. The "word of mouth" company also quoted and was very helpful, so we ended up with two substantive quotes. We were impressed by our research into the Solaredge technology (in particular a review by Mark Cavanagh in Brisbane, who has a blog) and the optimiser technology seemed to us to suit a house with the long axis being north/south, surrounded by trees and needing three arrays of panels. From the outset Goliath's front man Tom Morgan was helpful, made several suggestions about the proposed array and kept in close touch as we developed the proposal. As to the installation itself, David Stevens (Goliath's owner and the sign-off electrician) made a further suggestion about the array, which we adopted. David and his sidekick (apologies - I can't remember his name but David described him as "the best roof man in the business") couldn't have been more careful and respectful of our property and left no mess when they left. David also ensured that we understood how to work the remote monitoring system via a phone or computer app. Now, a word about price: in the event Goliath was slightly cheaper than the other substantive quote, but the difference wasn't enough for the decision to have been made on price alone. It's also worth noting that you get what you pay for, so I do wonder at the cut price deals being offered in some adverts. All in all, dealing with Tom and David has been a hassle free experience with Goliath delivering on time, doing what they said they'd do and keeping in close touch throughout. We thoroughly recommend Goliath. Show additional information
Excellent service, end to end process. Tom Morgan (Sale's manager) visited the property prior issuing quote to ensure all installation points were covered. Once the installation team turned up on time with all necessary equipment and parts to conduct the job fully with no corners cut.
I especially like how there was no hidden costs like with other companies I looked at.

Tom and his team are great guys, down to earth and know everything about solar and batteries and the best bit is they do not take you for a ride. They tell you how it is straight up.

I would highly recommend Goliath Electrical any day and when we move will for sure contact them again for another system.

Hi Sam,

Thanks again for the kind words and trusting Goliath Electrical for such a large financial investment. The installers still keep talking about your dog and who will be getting one first!

All the best with the new system from the Goliath Electrical Install Team!

Cheers again

still waiting for origin to change the meter Show additional information
Tom was so helpful and incredibly patient with my questions. I didn’t feel pressured and felt he provided the best service. The installation team was also very friendly and quick. The best part was after the installation I haven’t felt left behind now that it is complete. I have and will continue to recommend them to every one I know. Show additional information
Goliath Electrical did everything right. Ben provided detailed information about the solar system, facilitated the changeover with the electricity supplier, kept me informed, made a pre installation visit to check the layout, and took care of all the hassles. The installation of the system went exactly to plan. Extremely happy with the great service received from the entire Goliath Electrcial team. Show additional information

I found that Goliath Electrical to be very professional and quite approachable any time of the day or time of the week. Goliath's quote wasn't the cheapest but I found that the quote presentation and their knowledge of the product they sell and install to be at a higher standard than their competitors. Would definitely recommend them. Show additional information

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.
Show additional information
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
