Great Experience

Great experience from start to finish with Ben from Goliath Solar & Electrical.
Ben organized a very reasonable quote in a short time for what I wanted. He explained the details of the system and how it works as well.
Installation was booked and installed promptly by their professional tradesman, and it was up and running by the time they left.
A follow up call from Ben, explained my new system and how to organize a solar plan with my electricity provider.

Overall, I would recommend Goliath Solar and Electrical for anyone looking for a new solar system in Adelaide.

Great company. Highly recommend

Getting solar on our roof was a great experience! Tom worked hard to make sure we were happy with the size and location on our roof. Since having it installed we are seeing the benefits already! Thanks team

Very professional outfit

Goliath Solar and Electrical have been excellent throughout my dealings. Ben gave a couple of hours of his time at different stages of the process to answer all of our questions and did so with great knowledge. Goliath were able to bring forward the installation date by a couple of weeks from the initial indication, which was a bonus. All communications were professional and timely and gave confidence we made the right choice to give Goliath our business.

The install team arrived on time and were finished by 2.30 that afternoon. They went to some extra trouble to make the install very neat and the way they went about their work showed they have plenty of experience.

We chose Goliath of because of Ben's honest no fuss approach, they employ their own installation teams and the excellent reviews.

The best and easiest in the business

Every aspect of dealing with Goliath ( Tom and his staff and installers ) has been great, easy to deal with , everything done on or before time, recommend them very highly

Goliath Solar and Electrical have an exceptional business model.

I have found the entire process from initial contact to the installation and follow up to be completely professional and a pleasant experience.

My first point of contact with Dan was great, as he had plenty of experience and knowledge to answer my many questions and worked out a suitable system for my needs and give me a quote that I had no hesitation in accepting.
From there we repositioned the panels to suit what I wanted and there were a couple of visits to my home to ensure that everything would work electrically with the 3 sub boards and my need for full house backup.
Everything was communicated quickly and efficiently prior to the installation and all the work is done for you in relation to notifications to your retail supplier and SAPN.

Liam and his installation crew were on time and worked very efficiently on one of Adelaide's rather hot days.
They asked where I wanted the Battery, Inverter and Tesla Gateway positioned and set about getting the job done.
The job was initially booked in over a 2-day period, but with the efficiency of the crew they had everything in place and cleaned up by 3.30 on the first day.
They also had the system up and running and showed me the Tesla app before they left.
We were thoroughly impressed with the installation; it's not often you get a crew that do what they do and leave the place as neat, tidy and as clean as they did.

Dan has since followed up with some tips on how to use the Tesla App and to discuss what to do about getting the best rates to consider for future supply of electricity and feed in tariff. Another follow up call will be made once we know how we are using the system.

We have no hesitation in recommending Goliath Solar and Electrical to anyone in search of a solar system installation of your needs with a fantastic team of professionals focused on customer service.
Many thanks to Dan for making this process a great experience.

Great installer. Excellent communication and workmanship

The entire process was simple and worry free from start to finish. The customer service was excellent. They kept me updated the entire time and explained things in a clear manner which was easy to understand. The installers did an excellent job, especially considering the challenging pitch of my roof.

Seamless, simple and so worth it.

Could not fault our experience. We had great communication right from our quote to installation - it was straight forward and simple.
The team were friendly and courteous, everything was tidy from start to finish.

Very friendly and professional

Goliath was busy so had to wait for installation but the whole process was professional and went without a hitch and follow up personal and ongoing

Second Battery installation

We already have solar panels and one Tesla Powerwall 2 battery. This was installing another battery whilst maintaining similar functionality to the existing system.

A very smooth process - Tom and the team are very methodical and patient. Easy to do business with! We had specific requirements for our second Tesla Powerwall 2 battery and they took a lot of time and care to make sure that the outcome was exactly what I wanted.
And they succeeded.

The Sunny Cover is great - pity the first battery (installed by another firm) cannot have one fitted.

Sam , the lead installer was great. He turned up on time and made sure we understood what was happening and checked with us that the result was what we had hoped for. And it was. He updated the Tesla App and connected our Enphase reporting system to our new home WiFi, which I had not done since we changed some months ago.

He handled the heat and unusual (for Adelaide) humidity well.

He cleaned up after himself which was much appreciated.

Shining Bright: Goliath Solar Delivers Exceptional Service and Expertise

I am pleased to share my exceptional experience with Goliath Solar. I would like to extend a special shout out to Dan for his outstanding service. Goliath Solar not only offered a competitive price but also delivered the solar panels before the due date. Dan's custom service was truly remarkable, and he took the time to educate me about solar, which I found incredibly valuable.

I am sincerely thankful for the seamless process and the level of professionalism demonstrated by Dan and the entire team at Goliath Solar. I highly recommend their services to anyone in search of top-notch solar solutions. Thank you, Goliath Solar, and a big thank you to Dan for making this experience so positive.

One of the most professional companies I have ever dealt with!

From start to finish, the service from Goliath Solar has been exceptional. Daniel and the team have been amazing with his communication through every step of the process and continues to do so. They were able to meet a very tight timeframe when pre-working our home at the commencement of the building process to ensure the deadline was met. Since then they continued to ensure the installation was scheduled in the required times that best suited us, with minimum interruption. The installation team did such a great job, they were very fast, clean and showed up on time.
Now that everything is complete, they continue to communicate to ensure we are getting the best out of our system and that we are on the most competitive plan that suits our lifestyle.
A big thank you to the entire Goliath Solar and Electrical team.

Honest and reliable

Excellent service since first installation 2013.
The company replaced the inverter 2019 free of charge when they recognised a faulty component that I had not been aware of.
They have just re-installed the solar panels after my new roof at a very reasonable price and wihin a tight time frame.
I would highly recommend the company.

Easy and convenient installation, great communication throughout the whole process

Quoting was simple and Goliath were able to provide me with extensive details prior to the installation and throughout the entire process. On installation day, the team was on time and were able to accomodate any requirements that we had. Goliath were always available to answer any enquiries I had. They thoroughly explained the process to me and all details involved

Great experience from start to finish

Starting the search for solar installation was pretty daunting as there seem to be a lot of pushy salespeople in the industry. Not Goliath though - Tom was respectful, honest and provided options rather than pushing us one way or the other.

Most of the quotes we got were pretty comparable but we felt comfortable proceeding with Goliath.

The installation was quick and painless - for us anyway, maybe not the guys doing it! There were a couple of hiccups with our tiles which is to be expected - Goliath went above and beyond to resolve the issues with no impact on us.

Goliath's liaising with our electrician, the energy suppliers and SA Power Networks was brilliant. We barely had to do a thing. The follow up service and instruction has been great too.

Hooray. A one stop shop!

It was an absolute pleasure to deal with a group of professional, young and motivated people In this era of subcontracting with its associated lack of efficiency and often poor communication. The whole process is in house, hence no blame game, the buck stops with Goliath, simple!
My electrician suggested I take a look at Goliath, and I’m so glad I did. Watching the five lads go about their work on day one was a reminder of days gone by, where things are done well and once.
They all worked as an efficient team, and the results were easy to see.
They were punctual and tidy, and even thought about the aesthetics of the layout of the various components on the garage wall.
I used to work for a major Australian airline for over three decades. Sadly it has lost its way over the years, however dealing with Goliath brought back memories of better times when it was a truly great company.
In short, I couldn’t recommend Goliath more highly.

Solid honest company

Tom the owner was great to deal with. I got 6 quotes and goliath were actually the cheapest with the brands quoted on.
He supplied honest advice and answered all questions I had when other quotes made me question things.
Installers were friendly, efficient and respectful of noise with a young family.
Had some issues with internet and SA power networks which they helped sort out.
Would highly recommend goliath, they are promp to reply to questions after install. They care about customer support not just getting paid

Great service

We contacted Goliath after hearing recommendations from multiple people. The whole process was easy and the communication was amazing. The team were available on countless occasions to answer any questions and assist as required. We’ve only just had the panels installed yesterday and are waiting on AGL to change our metre over but we have further follow up arranged. The team have also provided information on the best retailers moving forward.

Goliath reps were courteous and professional from start to finish. Great communication throughout and workers on-site were well organised and efficient. These are good people to deal with.

Good communicators and a trouble free install

Goliath offered a comparable system, service, and warranty to other quotes I received, but at a better price.
Everyone I interacted with was friendly and answered any questions I had.
Install was neat and the site was left tidy afterwards. Everything happened within the quoted timeframes.

I'm really happy with the service and the system. It's been running for a little over a month now with no issues.

Great customer service

Was part of our new build and recommended by our builder but we could have chosen elsewhere. Key here was the great customer service, during the process, at handover and then 5 weeks after handover to make sure everything was working as it should. I suspect you could find cheaper but probably lesser quality and without the customer service. Would certainly recommend.

Great service and informative

The sales and quoting process were quick and painless. They understood my needs and quoted a system that fit my budget as well.

They walked me through all the different combinations and gave me the option to choose.

Installation was on time and the handover was great.

If you knew nothing about solar going in, you will come out and expert dealing with Goliath. Definitely go with them if you're on the fence.

Smooth seamless experience

Our quote experience was friendly, courteous, knowledgeable, no hard sell and no pressure.
We were advised at all stages of our installation progress with emails, phone calls and text messages.

Storm day installation

Tom and his team of installers went above and beyond. Such a professional crew, made the whole process very easy. Every contact was on time even on the day of installation they arrived amid the thunder and lightening, Installed the inverter in the garage then waited for the heavens to clear before completing the panels, Left the work site clean and stayed to help me with installing the app on my phone. Totally recommend this company.

Highly recommend Goliath Solar and Electrical

I recently retired following 38 years working in the electricity industry in SA and I was delighted to have Goliath Solar installed my solar system.

Goliath Solar is a highly professional and experienced company in the solar sector. Top marks for their communications skills.

Ben from sales/quoting was honest and knowledgeable. He kept me informed from start to finish and made the whole process effortless and enjoyable. Ben organised everything from quoting, grid connection, government rebate and installation.

Sam and the installation team were punctual, polite tidy and skillful. It was a pleasure to have the team working on site. They kept us informed throughout the day and finished the job on time. We appreciated their attention to detail. They did a fantastic job.

I’m extremely impressed with their after sales service which highlights their dedication and commitment towards their products and customers.

I highly recommend Goliath Solar and Electrical for your solar system.

Hassle Free Solar Install

The entire Goliath team were incredibly easy to deal with throughout the entire process. Daniel made the decision to sign with Goliath over others an easy choice. He was generous with his time and knowledge to ensure I was well-informed without ever feeling like I was being 'sold' something. The Installers and lead sparky, Jordy, were equally as efficient and pleasant, with the entire system up and running to take advantage of some late afternoon production. Thank you Goliath Solar and Electrical!

Efficient and Professional

I found interactions with Goliath to be very professional. Technology used extensively for communications which made it easy to keep track. All my questions were answered and I felt I wasn't wasting anyone's time. The installation team were fabulous. They arrived on time, were friendly, easy to talk to and most importantly cleaned up after themselves. Once installed Goliath discussed retailer options for best tariffs. With the pace of change in technology I had mid tier flagship panels installed. I installed a large system with a view to adding batteries within 12 months. Will be reaching out to Goliath when ready for batteries.

Highly recommended installer

My initial system was installed by Goliath 5 or so years ago, and I had no hesitation going back to them. Tom is still the point of contact and had a design and quote for a significant upgrade and battery in no time. All regulatory issues were handled by Goliath. Installation was quick and professional, with no mess. The team were polite and respectful, the system is exactly what I was looking for, and worked perfectly immediately.
Highly recommended.

When only the best will do!

From the outside Goliath were nothing short of amazing, presenting me with the facts and advice pertinent to the nuances with my install. This was particularly important in my case due to some complex shading issues present on my roof. Goliath's install was extremely tidy, which was especially important to me due to how particular I am about things. After the install, Goliath have followed up numerous times to confirm I have been happy with things to date and to check-in on how the system has been performing. If you're in Adelaide - Goliath should be at the top of your list of installers to get in touch with!

Fantastic business

Goliath has obviously developed an excellent business model as reflected in all aspects of their service.
After an initial phone call Daniel organised several face to face meetings (my preference) to deliver the information in relation to Solar Power.
The presentations were professional and he was open to the many questions relation to this new technology and how it functioned. The questions were answered succinctly indicating a sound knowledge base.
Time was given to digest the information for the best outcome including several diagrams for the most productive layout suited to the house.
Installation:
The team was punctual and very focussed with the installation on the roof and inverter. Efficiency, professionalism and good manners were continually reflected during the day.
All packaging and rubbish was removed and the worksite left spotless.
The App is amazing and is very informative and updates very quickly depending on what appliance is in usage.
Excellent customer service, a credit to the Trades and a job well done!!

Outstanding service

I would normally obtain at least 2 quotes for any job or service that I am considering at home but a family member had asked a friend about solar installation. This friend was forensic when looking into companies and was convinced that Goliath were by far the best in Adelaide. The family member was confident to use Goliath 5 years ago for solar and was completely happy with their service and products. I contacted Daniel at Goliath Solar who talked me through every aspect clearly, send emails with full information and satellite pictures of my property showing the positioning of the panels. I was so confident in Goliaths ability that I did not peruse any other quotes.
The installation worked like clockwork, the job was punctual and everything was left clean and tidy . Further contact was made with Daniel who discussed the best energy companies to consider for future supply of electricity and feed in of power.
This was one of the easiest and best managed of any project I have conducted in many decades.
