About Goliath Electrical, Solar Installers

Founded by electrician, David Stevens in 2012 to offer a reliable alternative to the solar industry giants, Goliath Solar & Electrical have ridden the wave of boom and bust that is the solar industry to become South Australia's local solar experts. With over 7 years in business and 2,000 completed installs, we are dedicated to providing honest, professional customer service and high quality solar systems, installed by our friendly electricians to consumers across the state. We care about our clients and doing the right thing by them, which is why we promise:

 We work solely with our own personally trained electricians, we don’t use sub-contractor installers

 Our solar consultants come from customer service backgrounds, are technically trained in the solar industry and don’t use pushy sales techniques. 

• Your quote will include everything, there will be no hidden charges.

 We custom design solar systems for each and every residential and commercial property, ensuring optimum results with our pre install site visits.

• Goliath will only source reputable panels and inverters for our clients that we trust and know will last, plus all products are purchased and supported locally.

 We value and appreciate our installers, their energy and commitment to doing a great job every time. Quite simply, our sparkies will take great care of you, rain, hail or shine.

All three were very helpful and competitive, but we got a slightly better price from

thank you for your help.

This was a difficult system to have approved by SA Network as my total system capacity exceeded their 5kw export limit and the Endphase S270 inverters had not yet been approved for export limiting. Goliath negotiated this approval and Tom Morgan from Goliath kept me fully informed right the way through. Once the approval had been granted installation was carried out in a week. The day came and was one of Adelaide's windiest and cooler days but the installation crew dodged the showers carried out the work with courtesy and in a good workperson way.

Tom from Goliath was great. He explained everything including all the info regarding getting my retailer to change my meter to a smart meter.
Install team was great & follow up support has also been good!
Would definitely recommend these guys!

Both quotes were detailed, and happy to answer any questions, and wanted to come out to make sure there would be no issues. Both used the same products which was also comforting. Show additional information
Tom did a great job of answering all the technical questions I had which helped close the deal. Installers did a great job working through one of the wettest days in Adelaide this winter dodging the rain but still managed to finish in 1 and 1/2 days. Show additional information
Goliath , so far, seem great. Only quote that considered over sizing the panels vs inverter. Have provided this feedback before. Painful part is still waiting for meter changeover from origin/acumen, within 30 days quoted currently at 44 days and none the wiser Show additional information
Excellent communication between sales and install team and then us the client. Offered alternatives specifically for our build. Very happy. Show additional information
Tom and the team from Goliath were only to happy to deal with numerous question with factual answers. Tom filled the paperwork to get the meter changed and coordinated the install for the same day. Having the same point of contact from initial call to post install is great. I would not hesitate to recommend Goliath Electricical if you are looking to get a solar install done.

Very strong focus on providing good service and keeping us informed. Highly recommend. Show additional information
Goliath have been great to deal with. Explained everything clearly and made the process of installing our solar system easy. The install itself was very tidy, the installers cleaned up afterwards and explained how to operate and monitor our system. We wanted quality over the cheapest price and I feel that is what we received from Goliath. Show additional information
They all sell the same stuff. EG the quality parts when you pay for it.
What you want is a good price with exceptional service. Look no further.
As an added bonus the guys that turned up could not have been nicer, more efficient, clean and helpful.
Can't recommend enough. A stunning expierance which is sadly unusual.

David and the team at Goliath Electrical are absolutely wonderful.
From the initial encounter to the supply and install my wife and I always knew we were in good hands.
The passion and commitment shines through certainly more than just a job for this crew.

Tom the salesman was great. He knew his stuff and wasn't at all pushy. Once we made the commitment to proceed, he guided us through the paperwork with SA Power Networks and our energy retailer all the other complexities leading up to install day.

On install day, David and his team of installers arrived on time as planned and everything went really smoothly. The team were friendly and explained how it all worked post-install. Everything was left neat and tidy and looks really good, and working as expected. After sales service has been excellent as well, with follow up calls and emails from Tom to ensure overall satisfaction.

I went with this company due to their great online reviews and will have no trouble recommending them to others.

We are happy with the service provided. Show additional information
Goliath was recommended by a colleague as well as being recommended online. I emailed a few places for quotes and Tom from Goliath came out and measured/ quoted before any others even bothered to reply to my email. Though not the outright cheapest quote, Goliath quoted a very competitive price and more importantly didn't cut corners on the components compared to others - hugely important when looking at a 20+ year investment. From the beginning Tom built trust and value into the experience and guided us every step of the way through dealing with our energy supplier to regular checkins to make sure we were happy up to and post install.
The system we now have is fantastic and great value. The quality of the installation is terrific and the professionalism of the install staff was 10/10. Thaelan led the team on the day who installed quickly and respectfully, with no fuss.
Ultimately I would highly recommend Goliath for solar in SA. They care, they have great integrity and they do exactly what they say they will when they promise to do it.

Excellent service from this company, went with them because they were a South Australian company. their price was a little bit higher than the other interstate company for a similar System but totally worth it, not regretting my decision one bit. Tom Morgan was fantastic from the initial quote to the follow up after installation, he arranged all the paper work and explained everything in detail about the position and placement of the panels for the best result during the site inspection visit. He was very punctual, which is rare these day. The two gentlemen who did the installation was also very punctual and efficient and did a great job and are very tidy. Highly recommend Goliath Electrical they are the epitome of 'Good old fashion service'. Show additional information

Great communication and friendly staff, awesome system. Love having the ability to monitor the daily usage of our power and how much energy the system is generating! Show additional information
Tom from Goliath Electrical looked after us very well.
He communicated with us very well at every stage of the process. His wasn't the cheapest quote, but by far the best value for money!
The installers were very professional and successfully installed the system on a terracotta roof on a miserable day, when I certainly wouldn't have gone on the roof, with absolutely no issues.
Their after sales service has also been outstanding, taking time to explain the finer details with me.
I have no hesitation recommending Goliath Electrical in the future.

Thank you very much

Ben and all the boys have been sensational! Constant communication from Ben mean't I always knew when and where things were happening. Great service from the installation boys as well.

They were quite good to deal with, listened to my concerns and got the job done promptly and by far the cheapest than other companies up to $1500 in one case for the same product! I would certainly recommend them let’s hope the system doesn’t cause any trouble hopefully not. Show additional information

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.
