Great service and follow up

After moving into a new home with solar panels, I wanted to take advantage of the current rebates. I shopped around, got quotes and found Goliath Solar the most responsive and professional to deal with, from the initial contact, to after the battery going online, Daniel especially was always on top of things, following up with me, answered all my questions. As it happens, they had installed the solar on the house I had purchased.
On the way, the installers rocked up punctual and within a few hours it was all literally done and dusted. Cleaned up after themselves leaving no trace except for the new battery. One of the installers was the same person that actually installed the solar panels a few years ago. The fact that he was still there is testament to the company already treating their staff well.
I would certainly recommend them to anyone wanting to get solar panels and/or battery installed.

Great Installer to deal with

The quoting process was straightforward and thorough. I was kept informed of the process the whole way through. The installers were friendly. They arrived on time and did a great job. They showed me how to do an emergency shut down. Follow up service since installation has been excellent which included help using the app. Overall a great company to deal with.

Great Installer. Fantastic Customer Service. Highly Recommend.

We had our 10.12kW solar system installed by Goliath Solar and Electrical 7 months ago.

Dealing with Tom from the quoting process through to the installation was a great experience.

before and also after installation.

Installation team was also very professional. Everything was completed efficiently and to a high standard.

So far the solar system is flawless.
Very happy with our choice of installer.

Great help with ubderstabding the whole process.

Goliath's Dan spent a lot of time talking me through different options to make sure I understood my choices ans that he understood what I was after in a solar panel and battery system. His team installed the system quickly and competently and I have been using it well ever since - it's exactly what I wanted from a team of locals I trust a lot. Definitely recommend Goliath to anyone thinking of installing solar panels and/or a battery.

Painless install and enduring support

Very easy to deal with, professional but down to earth. The process was seamless from initial call through to install and they gave options and recommendations across system size, model and location but also tweak to suit what you want. Chose Goliath based on the feedback from other installs and a demonstrated ability to resolve issues and continuously provide good service years after install.

Goliath Solar & Electrical review

Goliath Solar & Electrical have been excellent to deal with over the last 3 and a half years. They were referred to me by my daughter and son in law when they had their panels installed on their home in Panorama.

I used SolarQuotes website to check on them and found they were genuine and already had great reviews. Well done Finn and team..

Back in June 2022 after being totally dissatisfied with our 2kw inverter panel system and electricity prices soaring we engaged with Goliath about the potential for improvement.
They checked our address and used imagery of our home to assess what could be done and came up with a system that could generate our needs and for the future.

13.32kW solar system
Canadian Solar HiKu (Black Frame)
2 Fronius Primo 5.0-1 (5kW) inverters
Consumption Monitoring Device - Fronius Smart Meter
Grasol - Grace Racking

This system, the quality of the products, the expert installation (which was completed in one day) was amazing and credit goes to the team and the customer service at Goliath, especially Ben who helped us through the whole process and answered my many questions.

We did have a few issues over time but a quick call to Tom had him monitor what was occurring and he organised a technician (Liam?) to investigate one of our inverters promptly discovering the problem and organising a replacement part from Fronius. Quick and efficient.

After ever increasing power prices and diminishing feed in tariffs, we decided it was time for a battery. Ben at Goliath had been telling us to wait as battery prices were still high, developments were improving and, as was substantiated by Finn in SolarQuotes, not really effective yet for value and cost of return.
This all changed earlier this year when our bills were ever increasing and the FIT was atrocious.

We organised with Goliath to have a Tesla PW3 installed after discussion with Ben about the benefits of other types including the PW2.
This was in April/May just before the election and the Labor government's battery subsidy proposal.
We asked Goliath to put our request on hold until after the election.
They had a meeting and contacted their numerous battery proposal clients with an option to proceed with supply and installation after the election, which would incorporate the subsidy if Labor won or proceed if that wasn't the case. This resulted in the company Goliath securing supply before the on rush that occurred after the election.

The subsidy also got us thinking that the original cost of one battery now almost covered 2 batteries, so we asked if we could purchase the Tesla PW3 expansion unit.

Since our batteries were installed and switched on we have been receiving zero or negligible inputs from the grid and can now more efficiently charge our EV albeit with the granny charger

I think we were very fortunate to have a quality company like Goliath with their fully trained technicians and knowledgeable personnel in office to help and guide us along the way.

Thanks guys, and SolarQuotes!

Great installer with a fantastic team.

The team at Goliath Solar did a great installation, they were thorought with the quotes and conversations with me and on the 2 days they were here they checked with me about install location, going into the house and how it was all going.

The system was installed very cleanly with good conduits for the large cabling for the 3 phase Sigenergy system and they left the site with no mess.

This is the second install I've had with Goliath and they've been consistently great both times.

The follow up emails and phone calls from Tom have also been appreciated and very insightful.

Five star sales and service

I used Goliath Solar and Electrical a number of years ago to install solar panels. The service I received was excellent so when I recently decided to install a battery I went straight to Goliath and have been extremely happy with the sales and service I received. Everybody I have had contact with from start to finish have been knowledgeable and helpful. So far all my dealings with them has been exemplary and I would recommend them without reservation.

Great support and wealth of information

Tom was very patient over a long period of time. He is a wealth of information and took the time to explain the different battery options.

Excellent install

Very professional company to deal with from the quotation stage through install and follow up once the system was operational. They kept me informed regularly from acceptance of quote until install as took time for the battery to arrive in Australia. The installers were very knowledgeable and did a great job and cleaned up thoroughly afterwards. Would highly recommend Tom and the team from Goliath!

Sigenergy 16kwh Battery and Gateway install.

Tom at Goliath has provided another exceptional experience. They did my 13kwh panels and 8kwh Fronious system 5yrs ago, and just this week installed a Sigenergy 16kwh battery and 10kwh gateway system. Communication is always prompt, information is always true and transparent and Tom only designs the system I need for maximum value.

The installers are top shelf and I have not a single issue with either system since install dates, not one drama!
If I need after sales care, I ping Tom and he generally gives me a phone call within a day or so.

Pricing is right on par. The brands and service should be seen as a you get what you pay for scenario….Ill always pay a little more knowing these guys will be around in 10yrs time to help with any future warranty work.

Highly recommended.

Low pressure, high quality

The staff are what win me over. Tom was ultra low pressure, yet very informative. Good contact leading up to and post install.

The workers on site were also friendly and polite.

Install seems neat. Quality products. Fronius and Canadian solar. They installed my system 10 years ago with no hassle, so were top of my list when I needed an upgrade. No regrets.

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.

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.

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!

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!
