Goliath Solar was so easy to deal with one person one company. Not a retailer then a different company to do the install. Excellent install and product can't wait to see how it performs with a decent amount of daylight. Highly recommend Goliath for Solar.

"Exceptional Solar Installation and Sevice in Adelaide with Goliath Solar & Electrical"

This is my second time installing a solar system with Goliath Solar & Electrical. Tom is very experienced and knowledgeable, and you can always rely on his advice. They always use quality solar inverters and panels, and their prices are competitive for the products they offer. His installation team is highly professional, and beyond the perfect installation, they leave the site clean and tidy. I highly recommend contacting Tom if you’re considering a solar or battery system in Adelaide.

Goliath Solar and Electrical - fantastic installer!

Goliath Solar and Electrical were extremely professional and excellent to deal with. Starting with Dan who helped us throughout the process of selecting and sizing up a system that would suit our house and our growing family. All the way through to the installation process from the tradies and how professional, friendly, respectful and clean they were during the installation. Arrived on time, punctual and couldn’t have rated the whole process any better. Tradies stayed to show us how the app worked and had a follow up from Goliath in the coming weeks after to check in and give an update of our usage. 100% would recommend using Goliath Solar and Electrical for anyone here in South Australia. Fantastic company and installer for solar!

Great experience with Solar installation and aftercare support

A year ago I had solar panels installed by Goliath Solar and Electrical, and the experience was fantastic. Daniel, who managed the installation, was professional, knowledgeable, and attentive throughout the process. The entire team provided exceptional service, from start to finish. Their aftercare support has been outstanding, promptly addressing any concerns and ensuring my system runs smoothly. I highly recommend Goliath Solar and Electrical for their quality work and excellent customer service.

Fantastic experience all round

From the outset Tom went through the various options available to be able to make an informed decision. Any questions I had were answered thoroughly and there was no pressure to commit to anything.

Goliath dealt with all approvals, and the installation team was the best I have ever dealt with. On time, tidy, and knew what they were doing.

I'm very happy with how the whole process went and the system is running beautifully.

Professional Service from Start to Finish

From the follow up of our initial enquiry through to the information assistance, quoting and final installation all was done in a professional manner. The representative who stepped up through information and details on Solar panels was very helpful and a pleasure to communicate with. The quote was per our expectations and once approved by us installation went ahead a few days later by a team of punctual and experienced staff. Communication during the whole process was without fault and connection to the grid went ahead without delay. Instruction on use of the app for monitoring our input, etc was provided by one of the installers on completion on the install and we found he was fully informative on its use.

Very pleased with our experience and would recommend Goliath Solar & Electrical to anyone who is seeking Solar Panels to their home or business.

Fantastic installer and awesome customer service

Sales and quoting process was very thorough making the decision easy to go with Goliath. After receiving around 10 quotes from other companies, Goliath stood out with their solid reviews on SolarQuotes and Google. Pricing was also good value for the systems quoted across multiple installers.

Tom is very knowledgeable and approachable and was very helpful designing to my needs with great attention to detail that other companies missed in their quotes. Tom was great in suggesting the best placement options for panels, inverter and battery and was more than happy to talk through my concerns and questions. Tom was also very transparent in recommending brands and panels based on Goliath's years of experience.

Installation was great, the team were punctual, polite and tidy and powered through a hot day on the roof. Very impressed with how fast it was installed, they did a great job and were friendly and approachable.

Customer service and post-installation queries and monitoring was very much appreciated. After the installation Tom has assisted me with monitoring and checking the circuits are all on battery backup and solar generation is performing better than I expected.

Tom is a pleasure to chat to and I really feel looked after. I'm very chuffed with our solar system with battery backup. The Nectr offering with Goliath for finance and locking in electricity rates and feed-in was a good option for us. Definitely recommending to anyone looking to go solar.

Goliath, Our Only Choice

Goliath installed our solar system a couple of years ago and their service and expertise made them our go-to when we finally installed a battery about a year and a half later.

That experience cemented Goliath as our only choice for anything to do with solar power.

Recently we were thinking of expanding our system capacity so gave Ben at Goliath a call. He patiently talked through our needs to ensure we would get the full benefit of the expansion then gave us the options available.

Once we decided on things, Ben and the Goliath team handled everything as painlessly and seamlessly as before with Sam arriving with the installation team and getting to work.

Sam did suggest a slight change to better suit our roof and before long everything was installed and running.

While Sam was doing the commissioning he noticed a slight glitch in how the battery was operating and took the time to call tech support and fix the issue.

Goliath truly do take pride in the work they do and pay attention to the smallest details. Even my nephew who’s a commercial electrician said the way the lines and conduit were installed showed attention to detail and care.

Thanks again Ben, Sam and the Goliath team for a great job. We couldn’t be happier and suggest you give Goliath a call. You will not be disappointed.

Fantastic service and communication

Goliath was excellent to deal with during our new build. I had regular check up calls and constant communication throughout. The installers were professional and easy to deal with. Very happy and would definitely use them again.

Great Product, Price and Service

Goliath were recommended to me by a tradie friend. From the start the communication was excellent with the process and any questions comprehensively answered. Having done this for so long Goliath had excellent systems and processes in place which made me feel very comfortable. The quote was cheaper than a few other quotes I had and the quality of product was better. Install was just weeks after signing the quote and all went smoothly. Would recommend Goliath to anyone wanting to get Solar.

Should have done it sooner

Entire process was ridiculously smooth. Tom listened to my requirements and designed me a system catered to my needs. He was able to answer every question I had and provided me with all the information I needed to pull the trigger. They organized everything and I didn't need to wait long for an installation date. On the day, the install was done very efficiently and I was up and running early afternoon. Everything looks nice and neat with no mess left behind. Post sales support has very good so far with follow up calls to make sure everything was working as expected and plenty of documentation on how everything works and troubleshooting steps etc. I did not want cheap and nasty, I wanted a quality system with support I could rely on and received everything I asked for at a competitive price.

They also installed an external power point fed by the inverter in the event of a blackout which I never thought I would need - however in the first week I had a mid-day blackout and used this to charge some batteries I was using to get me through.

Very satisfied - highly recommend Goliath.

An efficient, professional and totally painless service from start to finish

I was impressed from the outset. During the initial phone call they were looking at satellite imagery of my house and suggesting options that would be appropriate for my usage and future needs. They sent two options which provided all the information I needed to make a decision.

For every step in the process I was kept totally informed so there was no confusion. Changes to schedules were easily catered for due to other work I was having done on the house. The installation was also seamless and the installer kept me constantly informed of what was happening. He showed me how to download the app and how to use it, and it is something I have been checking every day - and I like what I see! It shows me how much power is being fed back to the grid )and there's lots of it!), how much power I am using generated by my solar system and how much I am drawing from the grid. For the first time in ages I am actually looking forward to my next electricity bill.

Goliath did all the background work required - applying for Government incentives, notifying SA Power Networks, etc. Basically all I had to do during the entire process was decide which system I wanted, and pay for it - and the prices were very reasonable.

Great people make a great company

Every step in the process of dealing with Goliath was a great experience. From the quoting and explaining of the different options and pros and cons of various options was detailed and very helpful.
The install looks amazing, in fact, can barely see it up there. The team did a great job planning it out to minimise visual impact and then on day of install the small army of guys worked tirelessly and were so neat and tidy, wouldn’t have even known they were there.
Can’t recommend Goliath highly enough to anyone looking for a quality system installed by quality people!

Good service

Quoted for solar on new build, as building took way longer than expected, no pressure from sales contact, followed up with regular calls ( every couple of months). Due to length of build re quoted when time to install, ( was actually cheaper) install on request day installers very professional, kept informed of progress and provided good instructions for solar system and its usage.

Highly recommend, and will recommend

Was recommended to Goliath by a friend, and after receiving multiple quotes from other companies and doing my best to navigate the mindfield that is solar, I came back to Goliath. One of the big selling points for me was the time Ben took to understand what I wanted, and then explain to me why he was suggesting the system he was quoting on.
I was honest that I was getting other quotes, he was still happy to work me and answer my questions and in the end, I was confident that going with them was the best choice.
Install day happened without a problem, and follow up phone calls and emails to make sure everyone was running smoothly.
Within 24 hours, the system is up and running perfectly!

Excellent experience and communication

From start to finish the process was very easy and with Tom being excellent with his communication it made every step easy to understand.

Obviously very experienced and have the full wealth of knowledge. I had already done my own research so knew what I was getting into but they provide proper reassurance without being too sales-sy.

Install team were also great, and super friendly.

Fantastic experience, exceptional install.

Probably the best experience I’ve had with a local business in South Australia. Fantastic from the initial quotation through to installation. I’ve had the system for a few weeks now and the performance is exceptional. If you’re looking for quality advice or to have a new solar system installed, I highly recommend getting in touch with Ben and the team at Goliath.

A Great installation and service to match

We appointed Goliath for an installation on our Adelaide Hills home on the recommendation of Solar Quotes ( who we had used for a solar installation on our previous house in Melbourne ). Our primary concern was to use a reputable company , who would provide good and continued service post installation. We were not interested in chasing the cheapest price or using inferior solar panels provided by some advertisers on TV. Goliath assessed our particular requirements and provided a quote for 5kw system with 15 x 440kwh panels. Ben from Goliath went through the quote with us and a separate site visit was arranged prior to installation to ensure that mounting the panels on our roof would proceed without difficulties. The installation was arranged a few weeks later and completed with no problems. The system's performance can be accessed via the Solar edge app . Ben then did a follow up call to ensure there were no problems and provided advice on obtaining a better quote from our electrical supplier . This we did and obtained an improved offer relating to the feed in tariff.
We were very pleased with the service provided by Goliath. They take pride in their work and the reputation they have rightly earned, so would have no hesitation in recommending them for installation of solar systems.

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.

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.

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.

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.

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.
