GI Energy & Cargill Electrical Services provide and excellent service.
GI Energy (Solar) Brisbane, are a 5-star company in our understanding. We, my wife and I, had 3 companies quote for our installation, and GI Energy (Solar) was by far the most proficient in every concern. GI Energy (Solar) was not the dearest, nor the cheapest but it was the company that paid full attention to our needs, e.g. one company spent 5 minutes on the phone with us and then sent us a quote.At this point I must point out that my wife and I have had a working lifetime in the electronics, electrics, and mechanical fields.
The Sales Consultant, Richard Watrous, was very technically competent, very courteous, ensured we had full knowledge of the solar installation and all its ramifications.
The installation company, Cargill Electrical Services, Brisbane, was also a 5-star company in our understanding. The team were punctual, very courteous, answered all our questions (my wife and I are a nosey lot!), very adept both technically and industrially, and no rubbish was left on site. A further, but minor point, it is generally considered in the solar installation game that between 1 to 5 tiles may be broken during the installation; the Cargill Electrical Services team did not break a single tile.
All-in-all, both my wife and I readily recommend the combination of GI Energy (Solar) Brisbane and the Cargill Electrical Services, Brisbane, team to those looking for a solar installation that will give the best balance of cost, efficiency, peace-of-mind, etc..

Couldn't have hoped for much better!
Everything went extremely well without a single hitch. The Joel (the GI sales rep) contacted me almost immediately upon the referral and provided me a quote onn the same day. More importantly, he answered all of my questions and provided with a great deal of information which supplemented my own research. Ryan from Ryzelect and his crew did the installation. They were polite, professional, and extremely efficient. I was most relived that they adhered to safety protocols considering the very steep pitch of our roof and its exposures to strong winds. The panels look even better than I expected! Vanessa from customer service was excellent, always keeping me apprised of every step. Great job. Thanks to the whole team! ...and to Solar Quotes for not only the referrals but for providing me a useful and comprehensive source for all of the information.8 months later we asked Michael: "Are you happy with the performance of your system so far?"
Yes, absolutely! I am considering adding additional panels and a battery.

Happy Customer
Would most certainly recommend GI Energy to others. Sales and office staff were most helpful and professional. Unlike some other providers they were able to provide a system that gave us all of the features we requested.Installer were very professional, did a very neat job, and cleaned up well afterwards.

Difficult decision.
The prices were similar but we had to go with what we determined was the slightly better quality. Installation was on time and friendly. The grid connection was appreciated.Inverter rating: 5/5

GI Energy was outstanding
I contacted several solar installers, but none were as straight forward as Richard of Gi Energy, and as his quotation was competitive I choose them as the preferred installer. Vanessa's administration from quotation through to final certification was admirable, as was the installation itself, very professional. A great outcome.Our thanks to the team at Gi Energy, Jolyon Ellis

Very satisfied customer
Now six months since start up.No problems with installation or output. Savings are in line with GI predictions.
Good support from GI in a prolonged dispute with Alinta.
2 months later we asked Clyde: "Are you happy with the performance of your system so far?"
Yes in fact better than expected09 April 2022
Great outfit; professional install; quality system.
Sales person was very polite, friendly and professional. They suggested a system whilst still not trying to dictate my requirements, unlike some other outfits who refused to quote a three phase inverter when I specifically asked them to do so. Good to deal with through the entire process, keeping in regular contact to update us on the process and turning up promptly with a fortnight of paying the deposit to complete the install. Overall very happy with the process and the system so far.Inverter rating: 5/5

Some minor communication issues but good overall.
Quoting process very informative and helpful.Minor installation delay due to hardware lost in transit and some lost communication between sales and installers. Once underway very good installation team.
Grid connection all looked after, Very smooth connection.

Premium customer service
Peter from GI stepped us through every step of the process, helping us wade through various quotes and differing advice to identify what our needs were. The final price ended up slightly higher than some of the other quotes but I knew what I was getting was exactly what I needed.16 February 2022
Fantastic experience
I knew nothing in Solar before my installation, and got heeps of questions and unknown before I had contact with GI Energy. Their prompt response and solutions to my questions and issues surprised me in both pre and post installation. The Installer they recommended was punctual, efficient and the work was professional done, even tidy up all screws and bits on the roof top after job. Keep up guys.Panel rating: 5/5

User friendly service with lots of information
There seemed to be a lack of clear direction between the sales people a d installer as the installer asked us to provide the panel plan.24 January 2022
Great Instillation
Just had a 6.63kw micro inverter system installed. So far, great, very pleased with the output from the panels. Averaging well over 20kwh per day production. The whole process was made easy by GI Energy and Instillation was excellent, not the easiest install as we have cathedral ceilings but they look fabulous and they were very professional. I would definitely recommend. I can monitor the system daily on an app and see exactly what the panels are producing, what I am exporting/Importing from the grid.Panel rating: 5/5

Excellent experience
Sales process was excellent. Came to our property and explained everything in detailing, highlighting much of what you say on your website. 13kw system installed on the day - no issues whatsoever. Just waiting to hook with my energy supplier to start getting the benefits of it. Very good experience overall.8 months later we asked Jim: "Are you happy with the performance of your system so far?"
Really pleased with GI Energy Brisbane and the quality of the work they did on the day. My only slight issue is not with them but with my electricity provider who changed me (without consultation) to monthly bills and those bills seem to be creeping up. Yes it is summer but I need to look at the details - trust no one!. Other than that I know I have a fantastic system, professionally installed and doing what I expected it to do.02 January 2022

5 stars for GI Energy. From point of contact to installation. Very professional, prompt and efficient service22 December 2021
Efficient and Friendly Service
Every aspect of the process went smoothly. I felt confident that I was well informed. It started with the sales person who gave realistic information and time frames. The installation was done efficiently with friendly guys who took the time to answer any questions. The follow up after that was prompt. We would recommend GI Energy because the service was completed in a seamlessly efficient way.22 December 2021
Just good service
Outside of generally being helpful, actually followed up to ensure we were happy with the quotes sent. No the cheapest system quoted, but overall represented the better quality18 December 2021

GI Energy delivered a good Customer Experience.
Everybody in the process from sales/quote to installation and after service were helpful, engaged and responsive. I felt like i was under expert hands and whatever misgivings about the decision became a non factor.I thank Peter Boyle for his firm handling when i vacillated as he reminded me of what i told him what i wanted in my solar system :) and good job.

Oh what a solar!
The experience with GI Energy has been outstanding. The sales person was accurate, explained everything clearly without any hidden surprises. We had a pre inspection to finalise the plan and layout. After that the installation went pretty smoothly considering the rainy days around the actual installation day. The team worked hard not to let us down or to make us wait long to finalise the system. Highly recommended!Panel rating: 5/5

Very good pre and post sales support
Pre- and post-sales support has been excellent. The sub-contractor installer was a well known local company and they did the correct thing using a grinder to cut the roof tiles for the electrical cable. Another electrician told me to check for a grinder otherwise the roof tiles would be askew. The whole purchase and system process has been very professionally handle. Installer was punctual.Panel rating: 5/5

Excellent Solar Company
GI Energy helped us out heaps. All the other companies we spoke to just wanted to get as many panels on our roof as quickly as possible but GI spent ages with us and were patient until we were ready to install. The install was great and our bills have now gone from around $400 a month to only $24 a month, Couldn't be happier.We were installed about 3 months ago and the original salesperson just got back in touch last week to review our bills, talk us through the solar Wi-Fi monitoring again and make sure everything was working as it should.
We were actually quite taken back by how well looked after we were throughout the whole process. We were kept in the loop with everything that happened with getting approvals, install dates etc and everyone we spoke to at their office was really friendly and helpful.
I have already recommended them to a few mates and I will continue to do so.

Good customer service
Sales process was good but they didn't consider shade factors thoroughly.I had to bring it to their attention.
Installation was very good....tidy but they siliconed a broken tile instead of replacing it

Early signs are positive
We've only had the system for a few days so it's too early to give it a thorough review. We were fortunate to get up and running immediately on installation, because solar had been previously supplied to our address before the roof was replaced. The installers worked quickly and communicated well. They found one panel damaged when they unboxed it, but they wired the system to work without it and are coming today (only four days after install) to add in a replacement panel. GI Solar have been fantastic to deal with - very responsive and patient with all questions.25 October 2021
Awesome experience- well-priced, knowledgeable sales person and great service. Unbiased solar company.
Fantastic experience. Had Peter Boyle attend my property for a quote and found him to be very knowledgeable, passionate, unbiased and trustworthy. He spent a long time explaining the differences between various products and recommended products based on my requirements / preferences. There was no affiliation to any particular brand which was a refreshing change compared to other solar companies I received quotes from. GI energy have been around for a long time and involved in some large solar projects and their high reviews are a testament to the company and their employees. Would definitely recommend and use again :)Panel rating: 5/5

Expert and patience advice, quality products, friendly service
Tom was patient with all my questions, and he clearly knew his stuff. He was happy to explore different options that would suit our needs. He followed up on our progress but was friendly and understanding of the time we needed to decide. Vanessa was always friendly and thorough. Their processes and systems were professional, with detailed quotes. The installation team worked hard through some hard weather to make it happen.GI Energy clearly focus on quality products and long term service rather than cutting corners to lower a quote. I was happy to pay a bit extra for this, because it's worth it and I didn't want to cut corners with such a big and long term investment.

Great job done by all at GI Energy, cannot recommend them enough from Tom explaining everything so easily to understand to the electrician Byron and guys so professional, friendly and made sure l understood everything about our inverter and panels. Customer service has been A1. It took us awhile to find a company that not only was great quality but a good competitive price that we could trust.

Thoroughly recommend GI Energy
GI Energy did an outstanding job. first they answered all my questions and I did a lot of research before hand so had a lot of questions to ask. Peter was prompt, patient and thorough in his responses. the installation happened on the day as promised without a hitch and was professionally done, thoroughly recommend them to anybody.Vanessa also kept me up to date with progress, documentation and they let me know what the next step was and what to expect. Finally Peter contacted me afterwards to see if everything was ok and whether there were any issues

Mike and team were here at 7am until around 1pm.He showed me how the panels were going on and the fronius.He gave me a run down on how it all works and asked that I call if I have any problems and.advised that I call my energy company{Alinta}.Also coming back to check things out this week.01 October 2021
Informative and easy.
The quote process was quite good as the initial phone conversations went into some detail about constraints for the installations.The quote was competitive and the products quoted have good warranties.
The Grid approval process was easy and handled by the GI Energy team.
The installer was easy to deal with and came out for a site visit.
Since the install there were high rates of Grid Overvoltage but these were quickly looked into by GI Energy and their local installer. And so far seem to have been resolved.

A smooth and effective solar installation
The assessment and installation of the Solar system were handled professionally no matter which team member was involved throughout the process. We wish them equal success with future customers.

Great service from sale to installation!
Everything was seamless and professional. Tom in sales was fantastic and explained everything (multiple times so I understood) and knew the correct placement of our system & size required so we got the best return. He was very knowledgeable on the different brands and worked with us to stick to our budget. Come installation day - the installers were fantastic. I’ve never had such a clean, simple job happen at our house. Wouldn’t have even known they’d been working all day! Such a great experience all round!

All round excellent
Very happy with all parts to this experience. Started with great customer service from Richard and continued right through to Ryan and his team of installers. Everything was super easy and all options presented openly with honest advice. It felt warm and genuine from the outset.Too early to understand the impact on our bills, but the system has been cracking along a a great rate and it's still winter!
Would highly recommend a discussion with GI to see if they suit your needs.

Very happy with the service, installation & system performance.
Matt from GI Energy came out, looked over the property & surrounds & took the time to explain the system details & installation process. The quote arrived the same day & included comprehensive estimates of system performance, payback, etc... After looking at the proposed layout & location of the panels, I made a suggestion to split them to maximize the performance based on the orientation of the house & Matt agreed this would give us a slight advantage & they would do it at no additional cost - even though it would involve a little more time & materials to compete the job.Wait time for the install was only about a week or so & the installers arrived early on the day & were done by early afternoon. The installation is very tidy & if I had to fault it, I'd say it would have been better to mount the ENE facing panels higher on the roof as the house next door does shadow them first thing in the morning. It probably only delays the sun hitting them by 15-30 minutes though, so not a big deal.
After the install GI notified my supplier (Origin) & I received an email from then within a few days that they would be coming out to change the meter, which end up taking about 3 weeks.
Overall I'm very happy with the installation & the system is performing above the estimates Matt provided at the start of the process. We are feeding back way more than we're buying, so earning $1.50 - $2.00 credit per day on average.

From start to finish the whole process was easy. A knowledgeable sales person came to the house provided all the information we needed and within a day we had a quote.

From there the electrician was friendly and helpful and then the day of installation was great. The guys worked quickly and efficiently. It was a pleasure to hear them happy at work.

A Fantastic Experience
From the outset GI Energy has been very professional, guiding us through the cost of installation and explanation of the products they used.The installation was a breeze, the installers were punctual, polite and explained the whole process including the setting up of the app and guiding us through the it.
I would recommend GI Energy to anyone.
Fantastic company, made process super easy
Had a fantastic sales person, and being a local company, I wanted to support them. They made the whole process incredibly easy, liaised with finance and the grid so all I had to do was give them the green light and apply for my loan. Would 10/10 recommend them!Inverter rating: 5/5
