GEM Energy Solar Reviews

GEM made the process so easy

The sales person I dealt with was Garrett. He was incredibly polite and easy going and extremly helpful. Once I had made my decision, I dealt with Sofia who, once again, was easy going, easy to deal with and helpful. Seemed to know everything! The installation went smoothly and I was extremely impressed by the cleanliness of the site after they left. and also their working around a painful antenna.

The customer service has been spot on and Sofia has kept me in the loop the entire time. So impressed and would definitely use these guys again! I wish GEM all the best!

Excellent Solar Company

Before I sat with approximately 8-10 different companies, I researched all I could regarding solar for approximately 6 weeks. I wasn't parting with anywhere between $9-12,000 without having a good understanding of solar and the pitfalls of others. Every company had varying levels of subject matter knowledge and sales tactics.

Anyway, after careful consideration (I had three good options), I opted for GEM Energy, not only on the basis they are a trusted commercial installer (Australia Zoo), they provided me with realistic expectations and a value for money system. For an 8.3kW Sunpower (21 x 395w panels) System and Fronius Inverter they were well priced and within my budget. They were not the cheapest by a long way, nor the most expensive! The process from signing on the dotted line to installation was seamless. The install itself was a breeze and by the end of the day, you would not have thought a team of three where at the house. GEM Energy has its own team of dedicated installers and trusted contractors and the guys I dealt with, during the install, were amazingly passionate and the quality of the workmanship looks tremendous.

I now wait for the energy company to configure the meter before I can reap the benefits.

A huge thanks to Sofia at GEM Energy and the Install Team :-)

Quality Process and Product

Sales/quoting process was excellent, efficiently done, informative. Process smooth as clockwork. Best price. Top quality product. Streamlined process meant there was always someone to contact should the need arise. Installation went without a hitch. Personnel capable and made very little noise as they worked. Job completed in less than a day. The electrician was organised and professional, happy to answer any questions and re-explain if I needed clarification, did not leave until he was sure I had got the jist. Grid connected as of Wednesday and everything working perfectly. Yes, installers were polite. Would highly recommend them to anyone considering Solar. Show additional information

Very professional company through the entire process

We found them easy to communicate with- quick to respond. From the original quote through to follow up at end they were professional, responsive to the customer and easily accessible. Highly recommend them. Show additional information

Informative, excellent customer service

Seem less quoting process. Installation was great, the team where prompt and did a great job.
Customer service was spot on once we got the initial contact under control.

I engaged the company to discuss options to diagnose and rectify my solar inverter and battery management system and was met with less than satisfactory responses. I am continuing to diagnose the problem for them as no technician has been sent to my house locally to diagnose the issue. My losses are ongoing and no solution has been proposed.

Quality Company.

Pleasant sales process, asked Gem to quote on pacific brands, waiting on installation, Gem have kept me informed through each step so far.
Happy to date
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. Show additional information

Very good products very disappointing service and work ethic. Steer clear!

The only reason GEM Energy will get the stars they have is because the Fronius inverter and Q CEll solar panels (which I specifically asked for thanks to solarquotes website) are of good quality and I couldn't give zero stars for customer service. I do not recommend GEM Energy to anyone.
The salesman was charming, but the moment I signed the contract and paid my deposit everything changed.
Men turned up early in the morning unannounced (and got me out of my sickbed), before the due date. The installers (who were friendly and polite) did half the job then left me for nine days. I had solar panels stacked in my office, and broken tile pieces on the roof. During this time we had rain. I emailed them regarding these (and other) problems. I was told in a lengthy reply that, "in some cases we will still need a second day to finalize it (installation), which is the case with your installation" . To most people I would think the second day would follow the first day. They refused to offer me any gesture of good will for the stress and inconvenience they caused (albeit politely).
I also recommended they bring extra tiles, as they had exhausted the 10/12 tiles I had in my shed. My neighbours's high set house overlooks my lowset and they had alerted me to the fact that more tiles had been broken. Despite saying they would, they didn't. Finally, after everything was signed off, I got an independent builder to check my roof. He had to replace six more tiles. I wrote again to the installation manager. I sent the receipt for the tiles and labor. I also sent the receipt showing the roof had been checked, restored and re-pointed in 2018 to prove it was in good condition. I was told they didn't crack the tiles; they would pay for the tiles but not the labour.
When the installers finished they left a mess in my garage.
Next, regarding grid connection, Gem Energy sent the wrong details re IES - despite having a copy of our AGL account which caused complications and further delay.
Initially, when we were asked for the deposit, we were explicitly told they didn't take cheques. As I do not do internet banking, we had to make a special trip to the bank to transfer the money. I explained to the rep. that our local branch was closed so we would have to travel afield which is difficult. When they sent me the final bill, I discovered they do take cheques. Another bullet in the long list of disappointments.
I am glad this whole episode is over.
P.S. The lovely man at another solar company, (whose quote I turned down), has volunteered to keep an eye on my meter to ensure everything is working properly and I'm getting a good deal from my energy company. 'Chalk and cheese' springs to mind!

Dear Catherine, while we always try our best to deliver all of our customers the best experience possible, we also understand that things might not go as planned and that is why we advise our customers that installations usually take one day, but that a second day might be needed to complete the work. Due to delays caused by rain, we were not able to send someone out there the very next day, unfortunately. Please do understand that your request for a free hot water switch and a free smart meter (worth around $700) could not be approved as a gesture of good will.

We ask any tile customer to provide extra tiles on the day of installation. Being your tiles were quite old (it is correct that your roof was checked, restored and re-painted in 2018, however the tiles were not replaced back then and they are quite breakable), it is unfortunately quite common that any work done on your roof will result in some broken tiles needed to be replaced. We used the 10-12 spare tiles you had to replace all the ones that broke during our installation, so further tiles were required. In regards to your builder having to replace other broken tiles, we were provided no proof by the builder that the tiles replaced were damaged by our installers nor where they were located.

Lastly regarding your IES application, we have confirmed with Energex and with you that it had been approved prior installation and that we have followed all the steps correctly. The energy retailer chosen by you however, did not accept the request for the meter change (lodged with and approved by Energex) as they wanted the name of your husband on the application, while we had applied for it under your name. We followed their request straight away as communicated to you.

We have done our best to make sure all your concerns were addressed, we kept in touch with you throughout the whole installation process via phone and/or email to give you regular updates and we certainly delivered a very good quality installation. We are very sorry that we were not yet able to meet your expectations.

Should you have any other questions or concerns do not hesitate to contact us at anytime.

Flawless system

The initial salesman was very professional and knowledgeable about his product and able to answer all of our questions, the install got delayed as GEM wanted to ensure that the install was of the highest quality which it was, the team that did the install were friendly efficient and explained everything and answered all questions without hesitation and set everything up Show additional information

Great service and great customer experience

We are over the moon with our solar panels, the best investment we ever did. After being 9 months in production we have already a credit of $380 with the electricity provider. We actually stopped paying for electricity since the installation. So in short since instalment we saved $1,400 (9m). So in 4 years (if electricity rates don’t change, otherwise this period shortens) we’ll have paid off the solar installation. The solar panels and inverter all perform very well so far. Further great service, at every department of GEM Energy (sales, engineers, installers and administration) they are very friendly, responsive to all my questions, simply a great customer experience. I would refer anyone to GEM Energy. So thank you for everything. Show additional information

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.

Awesome experience the whole way through. Conor was a great support and very prompt and helpful. They Installed well before promised install date and had a great professional team of installers and take pride in what they do Show additional information

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)

Supplier Reply

Hi Bihn, thank you for your feedback. We are always improving our service and aim to resolve any inconveniences when they arise.

In this instance there were quite a few factors at play. As we discussed with you, due to a shortage of 320W panels the manufacturer could only deliver 310W panels and in order to install your system with no further delays, we added an extra 310W panel to make up for the changes and by doing so we have increased the size of your system from 6.4kW to 6.5kW. We were attempting to provide you with an upgrade at no extra charge due to the shortage in the product that we quoted. Unfortunately there was an error when sending the order through to our warehouse, and the same amount of panels were sent for the installation as originally quoted (20 instead of 21). This was a genuine mistake, proven by the fact that we added the correct wattage of the panels installed into the STC form sent to you for signature. We attempted to explain the matter to you and we fixed straight away after this was noticed back in May 2019.

We are deeply sorry for this mistake and have compensated you for the inconvenience caused.

Best wishes,

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

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

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

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.

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.
