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.


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:
Tom and the boys at Goliath were a pleasure to deal with. Tom replied with a quote next day then Tom came out for a site inspection a few days later. He ran through some different suggestions for panel placement to get the best results and fitted 6.65kW of Q Cell panels with a WiFi Fronius 5kW inverter with a 5+5 year warranty. Other so called cheaper installers quoted more for the same equipment even though they advertise thousands of $$$ cheaper on less quality components mainly chinese junk and to be honest the panel placement from these guys sitting in their call centre was ridiculous and would only generate late arvo and spoil the look at the front of the house when it wasn't needed, also some of these companies even suggested they had been installing for years but a simple ABN check reveals how long they were registered for. The system was pretty well much installed from the first quote till installation in under 5 weeks. While I was still receiving emails for quotes from other companies Goliath had installed the system. All the crew were friendly and polite and the installation took as Tom said 7.30am - 3pm. I have full confidence in Goliath if the system happens to have issues that the repair will be done ASAP as they receive an email from Fronius if the system has an issue aswell. I have no hesitation in recommending Goliath to anybody when you've tried the REST for a quote try the BEST. Goliath Solar & Electrical. Thanks a lot to Tom and the boys. We're making 37+kWh per day so far on the sunny days and summer isn't even here yet. Cheers.... Show additional information
Couldn't be happier with the service from Goliath. This was one of the first companies to contact me via the 3 quotes process from Solar Quotes. Ben was very knowledgable about the product, and was very patient in talking me through my many questions. Although I had done some research, I needed to understand oversizing which I had been warned about being a bad thing, and he explained the benefits of this and made me feel comfortable going with it.

He kept me informed every step of the way, unlike many companies who need to be hounded once the deposit is paid. The install team arrived on time, and by early afternoon the job was completed. They left everything spic and span, and Sam took the time to show me how to use the app etc. Ben also offered to to go through my first energy bill with me when I receive it, to ensure I understand how to calculate the savings/return.

I highly recommend Goliath. They are a down to earth team, who know their stuff and deliver as promised. Which is not so common these days.

It has been very easy to transact business with Goliath. After reading through good reviews about the company, I did not hesitate to go with them for solar system installation and upgrade. You can tell by their service that they are not after your money. They give practical and sound advice. They have gone over and beyond what is expected, calling clients on weekends and after-hours and communicate easily with text/email and phone calls. Show additional information
We built a new home and had solar panels installed with Goliath Electrical. Tom was very accommodating to the changes in our build schedule which we really appreciated. We were able to move straight into our new home with the panels already installed so we immediately were able to benefit from them.
Our new home is much larger than our last with a lot of appliances and a 20KW air-conditioning unit. The cost of running this house hold for electricity (and gas combined) is cheaper than running a small rental unit. This is due to the solar panels as well as the design of the house (in terms of window orientation and good insulation).
We also got quotes from other companies, some of them were cheaper and more expensive. Goliath offered very high quality panels for a reasonable price which is why we decided to go with them. They are good value for what you pay.
Tom was great with before after service installation. He is very informative in helping us to make the best decisions for our needs and always responds very promptly to any questions or queries we have - even months after installation. Highly recommended.

Using the Solar Quotes web site and then working with the 3 companies provided made for an easy experience. All 3 companies were good but Goliath Solar and Electrical provided the best price for the products and made the whole process as easy as buying a loaf of bread. Show additional information
Goliath was the first business to contact me after submitting my request for a quote. Ben talked me through all the jargon and was quick to come out and inspect the roof. He talked me through the benefits of oversizing the panels to get the benefit of the full 5kw. As mentioned above, their quote wasn't the cheapest of the three I received but I felt it was the best value as it provided 5 extra panels compared to the cheapest quote.
Installation of the solar system was delayed due to delays in the construction of my house, but when it was finally installed, Dave and the guys showed up right on time at 7:30am and had the system installed and generating power by around midday.
I highly recommend Goliath Electrical for solar panels.

Very happy to recommend Goliath electrical for Solar installation. We have worked with them to plan and complete a full installation in two stages 12 months apart. Sales staff are very knowledgeable and helpful as we planned the system installation, panel orientation and reviewed various options to suit our needs. The installation team were first rate, a young but top notch installation team leader. Show additional information
Great experience from start to finish, went the extra mile a few times to look after me. Could not speak more highly of Goliath. Show additional information
Most impressed with Goliath from first meeting with Ben who was patient, thorough and explained our options with pros and cons of each. He answered all our questions and once we decided to go with Goliath he kept us regularly informed as to where things were at in preinstallation and what we needed to do to meet requirements. The timeline he gave us for installation to occur was adhered to. On install day the guys arrived promptly and the job was completed efficiently. We have a terracotta roof and were worried about damage as they are very brittle tiles but only 4 were cracked which I think is wholly acceptable. They replaced them with spares we had on hand. Once finished Sam, the electrician, explained how the system worked including installing the link to monitor the smart meter very clearly. He also left his card so that we could call him if any issues arose. Worksite was left clean and tidy. System working before they left.
My wife and I have no hesitation in recommending Goliath for any solar needs.

Goliath Electrical have been totally professional from day one and a big thanks to Tom for his guidance and professional manner. There was no pressure placed on us just clear and honest direction and a competitive price. My wife and I contracted Goliath Electrical to install our Solar System for the following reasons which are paramount to our thinking.

1.Local Company , Local Workers and they have Apprentices which gives our kids a future.
2. Professional and only use proven reliable products. ( Special thanks to Tom )
3. Competitive pricing and great work ethic.

The System is now up and running with no issues , been a great experience from day one to installation completion. Would highly recommend.

I was very impressed with the service, installation and quality of product from Goliath Electrical. Luke was very polite, friendly and overall pleasant to deal with. The electricians came at the specified time, worked diligently and did a great job on the installation. It was a stress free process. Our panels are up and running, saving us $$ every day. On top of all this, the quality of the panels and inverter are excellent for what you pay. I would definitely recommend Goliath Electrical to my friends and family. Show additional information
There were delays due to the meter box being changed over, but the whole experience has been really good. Tom from Goliath Electrical was really good, contacting me a few times to let me know what i needed to do, and that it was still in progress. I love the new system. The 3 installation guys were excellent, finished the job in one day even though it was raining at the time. Show additional information
Goliath Electrical have been fantastic. No hard sell just the facts and a competitive price. There was an issue with installed panels not being identical to those ordered. I would never have known if David had not returned after the installation was complete and informed me. He then offered a generous amount off the final invoice as compensation for not installing as quoted. Honesty and integrity that can't be faulted. Rare commodities in a competitive industry.

From the start Luke was friendly, informative and professional. Luke explained every aspect of how solar works and talked us through the best system to suit our home, needs and price. Luke was knowledgeable and no question was left unanswered. Installation was easy and efficient as Luke and his team arranged everything, making it a very easy and stress free process. Thank you Goliath Electrical for making the experience seamless, we are now enjoying the benefits of creating and using our own energy. I will be recommending your services to others.

I can’t tell if the system is value for money until I firstly get a bill for electricity, and two , in fairness wait until the sun comes out. From what I’ve been able to ascertain so far it would appear that it will be fantastic.
As far as dealing with Goliath Electrical they were terrific. Everyone I dealt with had the same helpful approach and I would gladly recommend them. Their work is neat , tidy and efficiently co-ordinated. Good follow up service.

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.

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.
