Professional installation of solar panels, PW3 expansion, EV charger
I had solar panels replaced , PW3 expansion for PW2 and EV charger installed.Initially I was contacted about the possibility of the PW3 expansion of the existing PW2. When this became available I was contacted. Other companies didn't mention this possibility.
I had the small solar system replaced as well and an EV charger (Zappi) installed.
The installation team - electricians Callum, Cameron and teams ( sorry I forgot all the names) were professional, answered my questions and kept the worksite clean.
Follow up from the office through this process was prompt and efficient.
I recommend DQ Electrical for solar and associated work.

First Solar Install
This was our first foray into solar installation and after a recommendation from a neighbor we reached out to DQ electrical for a quote. The price was better than others that we had found so we booked in.On the day the install team was punctual, worked well and cleaned up afterwards.
Was very happy with the overall process including all communications prior to and after installation.
Would definitely recommend and use them again in the future

Excellent service throughout from initial enquiry to sales, supply and installation - and very price competitive
Very professional, prompt, efficient, communicative and thorough. Installation completed with a minimum of fuss.03 July 2026
Very Satisfied Second Time Customer
We've used DQ Electrical twice, the first time to remove an outdated small solar system, and install a much more efficient system with a battery, and the second time to expand the capacity of the battery. On both occasions the service by the sales, admin, technical and all staff has been price competitive, professional, prompt, polite, punctual, efficient, and tidy. We have without hesitation recommended DQ Electrical to friends and relatives who are contemplating solar installation.25 June 2026
Great installer and customer service
Regi was very helpful choosing battery and inverter and came out to help. Installation good. Bit delayed due to accident hold up etc good workers. Had to come back to finish due to rain! But polite and efficient and helped after to set up phone and app etc. Didn’t show me how to use charger or explain the system to me though. Not sure on details as only just installed this week10 June 2026

Wouldn't get anyone else to install our solar or battery
We had DQ Electrical install our solar panels a while ago and were very impressed with the salespeople and the installers then. The came they installed and then cleaned up their mess like new. Never had any issues with the solar panels. When it came time to have a battery installed, I didn't hesitate in ringing DQ Electrical again for a quote (I did ring other companies). We once again were impressed by the salesperson who came out, and the professionalism of the production of the quote, no question was to silly and was answered quickly and to our total satisfaction. They came again, they installed and cleaned up their mess. Great small company to deal withInverter rating: 5/5

Great all round company
The sales process was both informative and guided through the process the sales person was also very and accessible to answer any questions.Great installation team courtess and efficient combined with good back up from the office it was everything we could have hoped for.04 May 2026
Excellent experience. Quality install for a good price.
DQ Electrical installed my system two months ago and it has been smooth sailing. I'm very happy with the Sigen battery and overall it was an excellent experience, from helpful sales advice right through to a high quality install. I only have one gripe and that is the solar panels had a lot of smears of sunscreen on them from the hands of the installers. I was told that it would wash off with rain, but it hasn't thus far. It doesn't seem to have affected my solar panel output much, but it detracted from an otherwise excellent install process.Panel rating: 4/5

Lived up to their Review Stars!
This is for those who want to have confidence in their installer even when issues arise and knowing they will be there to deliver.I consider my self an educated customer so my experience with sales was a cake walk. They understood the design, my intentions and timelines. Booked well in advance in January for a new home build with predicted delays in occupancy but wanting to have the install finished before the May 1st battery rebate cut over. Price was competitive. No issues here.
Install date came and rain became an issue on the first day but the team booked in 2 days and made it work. The electrician and his team did a good job on site and were knowledgeable. They also assisted with some missing screws and missing washers on the roof during the install before they were covered by panels. The battery cabling is all discrete and it looks so clean.
Now the issue the was unfortunately only spotted after install was the model of the Aiko panels installed was incorrect due to an administrative error, standard S2 vs the expected S3 all black. Both sales and the company director contacted me directly with the details of where the error occurred, their reassurance they would remedy the mistake and their action plan. They offered a discount on the panels but did not pressure me to accept it in lieu of the correct panels. A clear demonstration of their dedication to customer satisfaction.
I asked for the correct panels to be installed and they moved quickly. The panels were no longer available so the upped the wattage in the same model and were ready to ship them in from out of state. The install was scheduled the following week and the system is now up and running. Bit of a short delay to get it back off the default export limit by SAPN as it had to be retested but that was resolved the following week.
Very happy with my system and I'm glad I went with DQ Electrical. Thank you!

Fantastic Installation
My salesman Nathan was very professional, understanding & explained all my questionsThe installation by Scott & Con was punctual, polite & extremely tidy, they answered questions with understanding.
Scott explained everything & was most helpful with the grid connection & use of the charger & explaining how to check what was happening.
Also the lady in the office was sooo helpful & understanding b4 the installation with all the problems I had due to illness & travel.
I felt DQ Electrical P/L were just so professional & they really went above and beyond for me as a customer.

After obaining four quotes for solar panels and battery DQ Electrical stood out as the best quote due not only to price but their professionalism in understanding what we required. There was no pressure and the process from start to finish went smoothly. They arrived on time with no delay, installation was done professionally and smoothly with everything explained and we are more than happy with the result.

Outstanding Solar & Battery Installation by DQ Electrical
I couldn’t be happier with my decision to choose DQ Electrical for my solar and battery installation. From start to finish, the experience was outstanding. Brenton, Harry and Ethan were absolutely fantastic — professional, knowledgeable and clearly a well coordinated team.Their workmanship was meticulous, and they took real pride in delivering a clean, high quality install. They were also incredibly friendly and easy to deal with, making the whole process smooth and stress free. It’s rare to see a crew work together so seamlessly, and it really showed in the final result.
I’m exceptionally happy with the system and the service I received. If you’re considering solar, I can’t recommend DQ Electrical highly enough.

Solar and Battery systems
I highly recommend DQ Electrical for the supply and installation of my solar and battery system.On site inspection and full explanation of how the system operates, all my questions were answered so I understood what to expect
The tradespeople are employed by DQ which is a massive plus,a nd they are excellent.
Thank you to everyone at DQ Electrical.

A great installation company. Highly recommend.
When our existing solar inverter died we sought 3 quotes for replacing the inverter and adding new panels. We also did research into the best panels available since our original purchase. DQ Electrical weren't the cheapest, but they were by far the best in explaining the process and providing top quality panels and inverter.The installation process went smoothly there were no delays from their original estimates and the installers arrived on time and finished well before the predicted end-time. All rubbish was cleared from the site
During the installation, we had a slight variation from the original quoted placement of the panels due to the proximity of existing panels, but the change was explained clearly to us and the effect on solar output was minimal. The resulting layout is just fine.
The installers instructed us on how to use the app that provides data on the panels.
Overall, we are very happy with the outcome and highly recommend.

5-Star Review for DQ Electrical
I recently had solar batteries and a new inverter installed by DQ Electrical, and the entire experience was exceptional from start to finish. The quality of service, communication, and workmanship was truly first?class. The quoting process was very informative, with multiple options presented. The communication was clear and continual throughout the process, informing me of the installation date, arrival time, etc. The installers explained the process on the day, power outage periods and explained how the system worked, including installing the application and explaining how it worked. They cleaned up all of their mess, including the removal of all rubbish from the premises.I want to make special mention of the installation team, Josh and Harry. These two are an outstanding duo and deserve to be recognised for the professionalism and dedication they bring to their work. Their depth of knowledge, attention to detail, and commitment to doing the job right were evident throughout the entire installation process. They are an absolute asset to DQ Electrical. They represent the company with integrity, skill, and a genuine customer?focused attitude.
I highly recommend DQ Electrical to anyone considering solar or battery solutions. The experience was smooth, transparent, and backed by a team you can trust. Excellent service all round and price competitive.

Exceptionally professional from initial quote until completion
The initial visit from and ongoing contact with the senior solar adviser was conducted in a very professional way. He took account of and understood our specific needs and designed a system that totally met these needs. The company kept us informed at all stages of the process leading up to the installation date and the installation itself was handled in an extremely well organised and non disruptive manner by a group of very competent and polite tradespeople. The explanation of the operation of the system, including the 'monitoring app' was handled well and we are totally confident with the ongoing professional support that is offered by the company.Panel rating: 5/5

Very positive from quote to follow up
From receiving the initial quote from Jason, through installation, and a small follow up issue, the team were responsive, courteous and professional. DQ Electrical provided a very competitive price and the installation process was neat, tidy and well communicated throughout.There was a minor issue with the output volume of the solar reading higher than the actual, but this was prompted sorted out between DQ and Sigenergy within a few days and is now functioning brilliantly.
I would highly recommend the team and DQ Electrical.

Great service, great team
After receiving 3 quotes, we decided to go with DQ Electrical.Nathan did an onsite inspection & was exceptional at designing our replacement solar system & installation of a battery.
His detailed proposal offered 3 options to choose from.
Luke & his team of 3 installers were friendly, punctual & professional. Everything was left neat & tidy & all packaging & the old panels were taken with them.
I have no hesitation in recommending DQ Electrical for your solar/battery installation.

Outstanding experience from start to finish!
I am extremely happy with my DQ Electrical experience from start to finish! They jumped at the opportunity to provide a battery and solar quote. Within a day or two an experienced person was onsite and able to provide a detailed quote that met all of my requirements. Pricing was the sharpest too! Communications in the lead up to installation were great and then the electricians did a wonderful job. They were polite and courteous even willing to thoroughly clean up after themselves. Their attention to detail was superb and I could not be happier with my installation. Highly recommended and I'll be asking for some more work soon ;)11 December 2025
There is a reason DQ Electrical is the best in SA
I can't fault DQ Electrical.I did due diligence and received three quotes, and DQ Electrical were the easy winners.
1. Communication - brilliant at every step.
2. Value for money - provided a much larger array and the biggest battery capacity for the same budget as others.
3. Integrity - A tricky installation does not put them off. They do not only seek out easy/quick jobs.
4. Bespoke - They will work HARD to find a way to get as many panels on the roof as they can - even if it means relocating a TV aerial.
5. Installation - elegant installation - with all ducting hidden wherever possible. Their in-wall/in-ceiling chasing is top-notch. All circuit breakers are nicely labelled. No handwritten sharpy scribbles!
We were happy to be added to the install wait list. DQ Electrical are busy because they are the best. It's worth the wait.

DQ Solar - Great Service
Steve from DQ solar offered great advice and was very knowledgeable!09 October 2025
System design / price / and sales process I can't rate DQ highly enough
There's a reason why DQ Electrical has a waiting period and a backlog of jobs.I'm more than happy to wait.
DQ Electrical is possibly the best in the game in Adelaide.
Steve was very knowledgeable, asked all the right questions, and didn't shame other installers or brands. Good, honest, straightforward advice.
DQ designed a system with significantly more capacity for generation and storage than the other quotes, at a similar cost.
Their systems for communication keep you very up to date with progress

Timely, quality and competitive prices
My brother and I shopped around and DQ was on our list as it was recommended by the electrician who built my house who said DQ use employed sparkies rather than contractors who get paid per panel. The panels installed were better quality that the other quote we were considering from RAA and DQ came to the party re price. Within weeks it was installed looking neat and I found myself thinking of why I didn’t do this earlier.

Great installation - all left clean and tidy
I appreciated their patience with the sales quoting process and communication around the installation date. Installation all went smoothly and the new battery looks great!25 September 2025
Great service
DQ electrical did a great job from quoting right through to installation and handover. The installers arrived on time and after the install took the time to show me how everything worked. They kept me informed throughout the process. I would recommend them if you are looking at installing solar at your property.09 September 2025
Good work, great team, very friendly
Yes all of the above. The whole process was effective03 September 2025
Thorough and on time
Sales person was knowledgeable and helpful, the customer service staff have always been accommodating and the installation went as expected. The installation engineers thoroughly checked everything was working before they left rather than skipping off early. This is the second time I have used DQ Electrical and would do so again.
Couldn't fault it
In November 2021 I had a Solar Panel and Backup Tesla Battery (phase 2) installed by DQ Electrical. That installation was carried out professionally and to my complete satisfaction and has operated without fault. Recently when checking the Tesla app, I found that my battery had been remotely turned off by Tesla the day before due to a technical fault. DQ advised me that the battery was turned off for safety reason and the problem would be rectified by them at no cost to me.DQ contacted me prior to the battery problem being fixed to advise that the battery would be replaced and suggested a Tesla Expansion Battery could be installed at the same which would double the capacity of battery storage available to me. The cost benefits to me were explained and I decided to proceed with the additional battery
The installation of the replacement battery and the expansion battery, both phase 3, have now been completed and are operating to my satisfaction
DQ Electrical tradesmen, Caleb and Nick carried out the changeover and installation with efficiency and are to be commended for their professionalism
In all my dealings with DQ Electrical I have found all staff to be courteous, friendly, polite and professional. I would recommend them for the installation of solar panels and batteries
