Excellent Advice, Top Quality Components, Excellent Installation and great advice!!!

GEM provided great technical advice and assistance and were able to put a quote together very quickly which remained constant throughout to completion.

They provided really good communications including advance advice on installation dates and times and quickly and clearly answered all of my questions and the installation was pleasant and fuss free, the installer even maximized the set up to match how our family use energy

I used GEM Energy firstly because I asked you guys about them and you suggested they were a good company. Second their service so far has been good. Using your website and advice I searched for the best product I could reasonably afford and Gem were flexible and able to supply what I wanted.
So I went with GEM and even though I haven’t had the installation done yet, the service has been spot on and the communication more than adequate.

The best system I could get on my roof

Vince was really helpful and offered me a number of choices. He also educated me enough to make an informed decision. I didnt understand what monitoring was for but I use that every day and couldnt be without it - Vince also helped my understand that too.

The installation was great - the team were professional, quick and thorough. There was one problem with the meter but they fixed that up immediately. The after sales service was some of the best I have seen in years.

All connection, follow up, metering and handover to my energy company was excellent. It all went through without issue (which never happens and compliments to Energy Australia for their great service) and I was able to see I was making money on my system as soon as I was switched over.

Beautifully done

Sales person was careful enough to make sure that I understood the scheme and process before signing me up. He is easily reachable over the phone, even outside of work hours.
Experienced a bit of hiccups with installations early on, but beyond that, it's a job executed well.
Would definitely recommend GEM Energy to others.

Bit of back and forth regarding the hardware due to the mad rush with the new solar scheme. So it was a tad annoying, took about 6months to get installed (not that I can really blame GEM for that I guess) Show additional information

This is our 2nd house we have installed solar in. The improvements in technology and battery is amazing. Our 1st home had a dedicated room with 6 very large lead acid battery banks that I had to monitor on a regular basis. Our current home now has a larger system and it all mounts on 1 wall and maintenance is a lot less. Show additional information

Dodgy installer

Be aware dodgy solar installer! Words of warning to all pass customers to check your solar panels to see if the wattage per panel is what is on your original contract when you sign to get it installed. I sign up to get 320w per panel x 20, what was installed on my roof was 310w per panel x 20. I only found out when I was about to sign the STC form.

After back and forth communication and negotiations, a resolution to this issue has now been reached. (updated 16/9/19)

Wonderful customer service

The staff at Gem were amazing. They kept in touch and followed up on any questions and concerns we had. I would strongly recommend Gem Energy to anyone who is looking to get solar installed. Show additional information

Great work

Professional for start to finish. Would certainly recommend Gem energy for Solar installation. Vincent who managed and Daniel who installed were great. Show additional information

Great customer service, excellent installers

Sales process required some back and forth communication in order to get best price. Delay in supply of panels lead to more than one install date. Installation team was great and very helpful. Had to call the company post install to email documents through required for government grant as they had forgot. Overall pleasant experience and good customer service. Show additional information

Paid deposit at end of April and install has been delayed twice due to non-availability of (Sunpower) panels. Latest install date date is 1 Jul. Another company said that they thought they were the only ones who installed Sunpower panels, so maybe this is a first time to install Sunpower panels - not sure. They recommended REC to begin with.

Best in the business.

We got a 6.7KW System of 21 Panels + 3.8KWh LG Battery installed with GEM through the QLD Gov Grant, it was a complicated process made all that simpler with Vincent Dyers help and professionalism as he guided me through the entire process from start to finish. The System was installed on the day that was agreed and the install team was very professional and pleasant, we had some minor delays due to weather and parts sourcing but nothing major, the install was wrapped up over the following 3 days. Once works were completed, everything was connected up with no problems at all. The sales team followed up after install and provided clarity as to the next steps in submitting the correct info for the grant. The whole process was a pleasant experience and I would highly recommend Vincent and the Gem Energy if you're looking at Solar anytime soon. Show additional information

Gem energy excells

The system development was excellent, I shopped around a lot before going with Gem Energy .
Our point of contact with Gem Energy was Vincent Dyer , Vincent worked very hard to come up with an excellent system for us and at a very competitive price .
The installation was very neat and well done , Swan electrical did a very neat install of the system .
Every one involved from start to finish of the system where all very helpful and polite .
The biggest hassle was with Ergon doing the final sign off of the system , but with a fair amount of pushing from Swan electrical and from Vincent at Gem Energy we got there .
Over all I’m very happy with the system , and very happy with everyone involved from sales to final install.

Fantastic service,, installation and support

From start to finish, GEM Energy has been a fantastic company to deal with. Starting with Vincent Dyer's fantastic efforts in scoping out and quoting the best array of panels and battery technology to meet our needs (we got numerous quotes and this worked out being the best value for money including offering high quality components and technology) Jodi's support in efficiently organising the installation and the fantastic follow up service we have received from the admin teams. Installation itself was professional, punctual, tidy, polite and everything is working perfectly. Throughout the whole process, we have received great information, updates, advice and assistance with understanding next steps. Very happy with our system and with our decision to go with GEM Energy - would highly recommend. Show additional information

What a Gem

Vincent at Gem Energy were fantastic from start to finish. We opted for the Solar and Battery Govt loan which the Vincent helped us get. Very happy with the install and the end product. Cheers. Show additional information

Quick and easy install. Good customer service

I received a quote from Vincent at Gem Energy for a Tesla solar battery. I was using the government grant and this process was a bit confusing, but Vincent was very helpful and guided me through the entire process from start to finish. The battery was installed on time and the team was very professional and pleasant. Everything was connected with no problems at all. The team followed up after install and provided assistance. This was a good experience and would recommend Vincent and the Gem Energy team for any solar and battery products. Show additional information

I originally left a very bad review for gem but since this time they have come through and done the right thing and reimbursed me all my out of pocket expenses so I have no issues with the company anymore and wish them the best for the future,the system is now working well.

Installation completed yesterday. Show additional information
We lost power the night of the system being installed. Gem had an electrician on to the problem the next day and when the problem still wasn’t solved they had 3 electricians there the next day. Show additional information
Thought I'd found a great company, only to find out once I'd paid for my system, the regular contact vanished along with the customer service.

A company that overpromises and under delivers.

System installed November 2018, system in the grid making electricity for me, February 2019.

We didnt get a solar system installed, we had a Tesla Powerwall 2 Battery storage system installed on an existing 5kw system. The review system doesnt allow for a battery only field.
David was extremely prompt with his quote, gave good advice and nothing was too much trouble. I had contacted several solar companies for a quote, getting a response from them was to say the least difficult. The worst case contacted me 10 days after my enquiry.

David was upfront on the wait time for installation which was spot on.

The pre install site inspection went off without a hitch.

The installation was brilliant. Allan and his team did a wonderful job, in terrible heat without compaints. They worked tirelessly to get the job done in a proffessional manner.
The job site was kept neat and tidy. Installation was finished within the same day with minimum disruptions to us.

The system is exceeding our expections - we have not used grid power since it was commissioned, 17 days now. We are self powered day and night and even export some to the grid. Couldn't be happier.

Jodie, David and all the staff we had dealings with are lovely people that went out of their way to answer any queries we had.

Well done guys. will highly recommend you to all and sundry.

I Don't think I can express in words how happy I have been with the service and system installed by GEM Energy.

Every dealing with them has been amazing from the quoting period to the installation (Jack was excellent all through the quoting process and our design was a trickier layout thanks to difficulty with our roof layout and the hot water system installed by another company being put in the centre of one section of roof rather than on the side where it should have been.....). GEM Energy were able to work around this and provide us with the best possible outcome working in the limitations caused by others. Booking it in has then been very easy with Jodie being excellent to deal with and the installers have been outstanding.

Polite, professional, hard working and they just got in and completed the job despite the heat.

Gem Energy worked with us to tie in with our roof being restored (cleaning and painting etc) by installing the feet first and then coming back after the roof had been done to perform the rest of the installation.

So far the panels are exceeding our expectations based on initial generation. I am looking forward to seeing our first full bill to see the difference.

From the initial quote, through the planning / installation coordination, the install and now with a working 8.5kw system - nothing short or wrapped!

The installation manager Jodie was great in coordinating dates, the boys that installed where great and very respectful of the fact they were coming into our home!

The best thing is that the solar generation exceeds what I was quoted (undersold and over delivered).!

On a side note - I have spoken to probably 8 different solar companies before I was comfortable to move ahead with Gem... Jack and his company have restored my faith in that not all solar guys are sharks in suits!! (PS - Jack doesn’t do suits).

Exceptional service and value from David GILLIES at GEM, who really looked after us from start to finish! Thanks for the great deal Dave!! Show additional information
We haven't had the system installed yet. Paid the deposit on the 24th Sept with a 3week lead in time. I sent an email on the 26th Oct asking where we were up to....with no reply. Rang today and were told we should hear early next week when they are installing. Don't mind a delay as long as we are kept informed. Apparently installer shortages. Hoping the system is as good as the reviews. Show additional information
Jake, Ben and all the staff at Gem Energy Australia,

I was left speechless this afternoon, which is not a common occurrence, with the delivery of the most beautiful bouquet of flowers. This is certainly out of left field as I have not known any company that would have done this. I am so gob smacked and cannot thank you enough. It made my day and cannot stop smiling when I look at the flowers.

It has been a pleasure to deal with you all especially you Jake and Ben also. As I have expressed previously of how great it has been throughout this order and installation. And we must give accolades to Luke and his apprentice, Jacq, with their visible expertise through the installation of the system.

I will definitely be recommending you all to our friends and associates as to how professional you have conducted yourselves, we couldn't be happier.

A huge thank you again.

Communication throughout the process, from enquiry to the installation was excellent. Jake, the State Manager, explained features and benefits well and kept in touch until after the job was completed. Jodie, the Installation Manager, provided regular updates on requirements and contractor liaison. The panels were installed in a day and look great. Show additional information
