Highly recommended

Goliath Solar installed my Tesla Power Wall battery, and from start to finish, the experience was seamless and professional.

They took the time to explain every step of the process, ensuring I fully understood how everything would work. Their careful planning prior to the installation was impressive; they assessed my needs and tailored the solution to fit perfectly.

Overall, Goliath Solar were professional and cost competitive. To have this backed up with great support and excellent communication makes them hard to look past if you're trying to find a reliable company to install a battery.

Excellent service and installation of solar panels

The sales and quoting process was excellent, Dan was very thorough, helpful and knowledgeable- he was able to provide a competitive quote and was flexible in considering our needs and configuring a system well designed for our property. He was transparent regarding all costs involved and helped us to understand in simple terms how everything would run. The installation ran smoothly and punctually as planned- the team were very friendly, respectful, tidy and their communication was excellent. All aspects of the customer service have been fantastic, including connecting the system to the grid, providing warranties, certificates and user manuals, contacting the electricity provider to install a new meter as well as running through the smart app to explain how things work and how to optimise the system. The follow up service has been as strong as the sales service and the whole process has been seamless. Thank you!

Fantastic Service

Installer turned up on time, explained what was about to occur. Any issues that the installer encountered, they stopped and explained how they were going tackle the problem. Once system installed, explained how to operate the battery application and how to interpret the data being shown on the app. Cleaned up and took away any rubbish. The whole process from receiving a quote to full installation was seamless. The after sales follow up and explanation was excellent.

Great Design and Install Process

Tom Morgan and his installation team have been fantastic liaising with our builder to install a PV array and battery system to suit our needs. Goliath was very patient and prepared to answer all of our questions to ensure that we achieved our solar objectives. The communication all through the design and installation process has been brilliant and very personal. Goliath also carries out regular checks to ensure the system is performing according to specifications.

Smooth process from start to finish!communication from the beginning to the end was great and after service very good! Installation and setup were spot on..

Communication first rate!!

Goliath were incredibly good to deal with.
Work was completed on time and things were left clean always.

The thing that really impressed my family, that really stood out - was the clear communication and explanation about how the system worked.

Goliath were also super honest and didn't try to upsell in any way whatsoever.

Used Goliath for panel install, and now a battery

In 2019 we installed 7.8 kw of solar panels with a Fronius inverter. We had a minor issue a couple of years ago, and Goliath actually contacted us about it, and sent an electrician out to fix it at no cost to us. The system is still performing very well, but our feed in tariff has dwindled over time. With the new battery rebate initiative, we decided it was time to get some storage, and Goliath ( Tom, the owner) provided a comprehensive quote for a Tesla unit with 13.5 kw hours of usable power. They were able to fit it very promptly-in fact we are set up for commissioning well before the scheme start date of 1 July 2025. The install was pretty labour intensive, but Jordan and Lewis, who are employed by Goliath, did a really neat job of placing the battery and gateway box in an ideal exterior location, given that room was tight in our courtyard home’s garage. The lads even cleaned up very thoroughly at jobs end. I’ll write another update on how the battery system performs after commissioning, but given the previous solar panel install and the job thus far I’m very confident of a successful outcome.

An overall great experience

From day one communication with Goliath has been fantastic. They have provided a lot of information with the solar system/battery and the process. I have had a few different trades doing work lately and the Goliath guys were easily the best. All the workers were punctual great to deal with, polite and at the end of the job you would not know they had been there. They left no mess! I definitely would recommend Goliath Electrical.

Very happy with all aspects of my interactions with Goliath

Sales/quoting process was good….. no pressure applied.
Installation went well, they were friendly, polite and helpful. Cleaned up on leaving.
Assistance continues after installation and encouraged to ask questions (even in the future).
Over all a good experience and I am happy with the system thus far.
Would be happy to recommend Goliath.

Consistent reliable Company

We have used Goliath Solar & Electrical multiple times now for solar, backup batteries & most recently a smart electric charger. Tom has extensive product knowledge & explains everything so it’s easy to understand. Installers are always polite, professional & mindful of cleaning areas where they have worked. The follow up calls at a time you choose after installation are also great so you can use the product for a few days then go over any questions you may then have. Overall the whole team takes pride in what they do which is very commendable these days.

Great Team

A great small business, didn't get the hard sell, this is so refreshing. They provided factual advice, and unbiased reading material to help you make a decision. Installation crew were a hard working team, polite and respectful, as a female at home by myself, I felt comfortable. I was kept up to date with the process throughout the day. The placing of cables/conduit was neat and well thought out. I was shown how to use the app and they organised the grid connection. Awesome!

Outstanding professional company

Goliath installed our panels and inverter six years ago. They gave excellent advice and completed the job with the utmost care and skilled workmanship. Their communication was excellent and they always arrived on time.
Since then we have had to replace our switchboard and, again, they were right there to re connect the inverter and get everything up and running
Always ready to help out!!

Great long term support

Called Goliath as the power to my 6.5 year old inverter was off. They rang back after looking up my details and pulling up photos of the install and stepped me through the correct reset procedure (circuit breaker had tripped).

That they responded so promptly and had my records from so long ago is a testament to their great service.

I left a good review after the install and now I am even happier I went with Goliath.

Completely satisfied.

Goliath came with a great recommendation from family who had a previous installation, always a good start. From the beginning communication was prompt and detailed whether by phone or email. The options provided where clear so that in making a decision we were confident that the installation would meet our needs and budget. The instillation team came on time, explained the process and time frames. It was obvious that they were knowledgeable and competent. Installation went without a hitch. The system and monitoring app was up and running with a clear explanation about how it all worked. They cleaned up without any mess left behind. Very respectful and polite crew. The follow up call was next morning was comprehensive. What was particularly useful was an explanation about dealing with utilities, SA Power and energy retailer. Connecting to the grid, testing of the system, reconfiguration of the meter and anything else that was required was organised by Goliath. Thanks to Daniel (Sales) and Jordan (Team leader) and the rest of the installation team. I would recommend Goliath to anyone thinking of doing solar.

Excellent service

Goliath provided comprehensive guidance throughout the installation process, addressing all my inquiries and concerns. I highly recommend their services. It is advisable to avoid reputable solar companies that may close down before the warranty expires.

Outstanding quality service and product

We received fantastic customer service through the quoting stage all the way through to installation.

We felt there were no ‘salesy’ techniques pushed on us throughout our quoting process, we simply had information freely shared with us to make informed decisions on the best solar system to suit our needs ?? No question was too hard.

On the day of installation the team were all very kind and polite and took great care around the home. We were shown how to use our system and how to sign up to the app to monitor our electricity usage. The installation was incredibly tidy and of high quality.

We were so impressed with the outstanding service of everyone involved!

The products available are meticulously selected by Goliath to provide the best products on the market.

Awesome experience

I had a 6.6kW solar system installed on my house by Goliath Solar, and the entire experience was fantastic from start to finish. From the very first interaction, I could tell I was in good hands.

A big shoutout to Dan, who made the whole process so smooth and easy. They were super helpful and took the time to explain everything - no pressure, just clear information. It really felt like they had my best interests at heart. I had a ton of questions about how solar would work for my home, and Dan answered all of them without hesitation, making sure I understood every step along the way.

The installation itself went without a hitch. The team showed up on time, worked quickly, and made sure everything was set up perfectly. They even took the time to walk me through how the system works before they left.

I’m really excited about having solar power now, and I’m already seeing some great results. Overall, this was a smooth, hassle-free experience, and I’m so glad I chose Goliath Solar. Highly recommend them if you’re thinking about going solar!

Allround Great Service

From quoting to final installation has been totally smooth and stress free....
Goliath worked with us as we were having our roof painted first so they pre installed the railing brackets so not to disturb the tiles later.
They waited till our painting was complete then installed solar panels the following week.
The installers were polite.. tidy.. meticulous with every facate from panels to inverter install.... Being a tradie myself i am fussy and OCD with straight lines and ascetics...
Our salesman Tom walked us thru operational details after install and will follow up again in a weeks time after our energy provider does their remote access login....
Very happy & pleased with the whole process.
Fully recommend them to all
Pictures doesnt do them justice
Looks perfect IRL

Thanks Goliath Team

Cheers

Beat in the business for quality and customer service.

From start to finish our consultant Ben made the process easy.
System was customised to fit and maximise panels on our unique roof type.
Whilst not the cheapest option, you get what you pay for with Goliath.
Install was quick and clean. 36 panels up in 1 day. The techs on site communicated well and cleaned up after themselves.
Ongoing support has been great, the app works well and is easy to use.
Highly recommend Goliath Solar.

Very happy all round with the Goliath team, accommodated my disability context also

My extensive questions were all answered with patience. The quotes were honest without the dodgy approaches used by other installers when providing me with quotes (to make the ROI look better than it really is etc). I have severe disability and am mostly bedridden and they accommodated me as much as possible with the install which I really appreciated. Kindness and respect throughout. The literally only thing I could fault them on out of everything was that they weren't able to connect to my battery in the Tesla app for me on install day and said they'd get Tesla to do it remotely which didn't happen (but I figured it out myself later on and they checked in the post install call that I'd been able to do so). They organised all the pre & post install paperwork and made the process as easy as possible for me which was greatly appreciated also. They've said they're always there if any issues crop up so post install service has been great too.

I'd highly recommend Goliath to anyone looking to get solar/battery.

Excellent system design and customer service

Dan and the team at Goliath were excellent to deal with. Extremely knowledgeable and designed a system that worked well with the nuances of my roof. They didn't try to oversell me and listened carefully.

Since the install they have been in regular contact to make sure I'm getting a good deal from my retailer and are available for ongoing support should I need it.

Solar Energy enquiries without limits

I can’t say enough good things about Goliath Solar! I’ve had solar panels for over 6 years, and their customer service has been nothing short of amazing. No matter when I reach out, they are always there to help with expert advice and solutions. It’s so rare to find a company that consistently goes above and beyond, but Goliath Solar truly does. Whether it’s routine maintenance or a simple question, they are always ready to assist and make sure everything is running smoothly. I highly recommend them to anyone considering solar power—trust me, you won’t regret it!

An exceptional experience on all fronts

I wish all our home renovations went as well as our Solar Installation did. The entire process was great with everyone from Goliath being very professional as well as friendly and timely through quoting, installation and hand over. We had a tiled roof that was very suspectable to being damaged (chipped tiles) if care wasn't taken and the guys took great care and minimised damage. The installation looked very well finished in terms of wiring etc. After install we had some dramas with our energy provider to get solar credits set up and Goliath was awesome at helping me navigate when they could have quite fairly said that that was not their problem. Highly recommended!

Quality service and product. A seamless process.

Dan was brilliant from the outset, explaining the process and coordinating the installation and set-up of the system. His communication was outstanding. He was responsive, professional, and explained things that made it easy to understand and make decisions. The installers arrived on time and worked in extreme heat to get the job done. All the work is performed by the company. The follow-up service has been great and again Dan has taken responsibility to ensure the system is operating correctly, provide advice on how to get the most of the system, and get me the best deal from energy providers. I literally have not had to a thing. If you’re thinking of cost cutting and going with a cheaper company, don’t. The quality of the service and product itself is well worth it and the pricing is very reasonable. I could not be happier. I highly recommend Goliath. You won’t be disappointed.
