Exemplary Professional Service
4 days agoNew
MDS provided me with extremely professional service.
I had several companies come out to my house via SolarQuotes, and others that I directly contacted (4 in total) and MDS were the ONLY company out of all their competitiors that demonstrated:
- (1) eagerness and competence with the electrical and solar design (my house required dedicated conduit to be run, had a complex roof design etc. which other companies didn't want to and could not address)
- (2) high level of professionalism indicated by clear communication, physical inspection, explanation of their plan
- (3) very approachable
I need to highlight as well that they provided excellent post-installation support. I did have some issues post install however MDS took personal responsibility each time, responded immediately to my questions, and even on a separate occassion fixed issues with my roof that were unrelated to their solar install.
I cannot comment on whether the cost is competitive (although I think it is - approx $13k for a 7.4kw solar system with a Sigen 16kw battery with underground conduit run), however, their professionalism provided me the confidence that they had done an excellent job and will continue to provide support into the future.
I can recommend their services.

Hi, I would highly recommend this group of installers.
They have been extremely efficient, well priced and really easy to deal with. I’m also an electrician, so I can confidently say they did well.They have good and accurate advice, recommended really good products and were really punctual with getting the paperwork done.

Quality experience
We asked for 3 quotes from Solarquotes and found that Dave Mahoney's approach and presentation stood out from the start. We liked that Dave and Evan are a local small business and both qualified electricians experienced at solar system design and installation. From the start we were talking with practical people who understood all aspects of the project and who were actually going to do the work.I remember Dave saying "we care about doing a good job that you will be happy with because this is my business and I will be the one giving you after sales service". He made suggestions which saved us money.
We had to wait a while of course, but communication was excellent and the job was done with minimal delays, there was no damage or difficulty what so ever.
The system is fantastic, we couldn't be happier.
Thoroughly recommend Mahoney and Da Silva.

Great Installation experience
Choosing an installer was initially worrying however I am very happy I chose Mahoney and Da Silva. Dave and Evan were extremely knowledgeable, very good to deal with even when my requests made things harder, and importantly they are top notch electricians which is important for these installations. They cleaned up, took care of my property, and were generally a pleasure to deal with. And pricing was very competitive for quality installers. I thoroughly recommend selecting them for any solar / battery projects.Panel rating: 5/5

Great guys to deal with and professional installation
They provided answers to our queries promptly and ready to understand. We would recommend.We had solar (jinko), battery and gateway (sigengery) installed.
We have a small roof space and Dave was able quote and supply 510w panels. Any post installation issues were resolved promptly.
They kept us informed of the single phase inverter recall and replaced without any issues.

Fantastic install
From start to finish, Dave and Evan demonstrated the utmost professionalism, guiding us through every step of our solar journey with clarity and patience. They responded to all our questions promptly and provided explanations that made everything easy to understand. We needed a flexible system to which more panels could be added with future renovations. Their willingness to collaborate when planning and when an unexpected issue arose during installation was greatly appreciated. They took the time to listen to our concerns and worked closely with us to find an effective resolution. Dave and Evan take pride in their work, ensuring that every detail was handled meticulously. The system installed not only suits our specific needs but looks great as well. Their professionalism, communication, and genuine care for their work sets them apart.Panel rating: 5/5

I couldn’t be happier with our new solar and battery system or the team that installed it
Outstanding trustworthy service. From the very first quote through to full connection to the grid, the entire process was seamless and professionally handled. The team’s dedication and attention to detail really stood out — they went above and beyond to ensure everything was done right.What impressed me most was their ability to adapt on the fly. When unexpected challenges came up during installation that hadn’t been visible during the site quote, they were able to quickly redesign elements to work around the problem without any delay or cost involved.
The communication was outstanding throughout the journey, the connection to the grid (for me) was seamless, all I got was a email from the energy provider asking me to accept it was happening.
It’s rare to see such professionalism, transparency, and problem-solving skill all in one team. I highly recommend David and Evan to anyone considering solar.

Great service, cost and installation.
These guys were great, certainly way better than the first installer who put a system on 5 years prior. They were timely, very responsive and took on all my requests. The quality of the install was great, very neat, and I have recommended them to a number of neighbours all of which now have one of their systems. I would very highly recommended you use them.Inverter rating: 5/5

Great Installation and Job Well Done
We had just installed solar panels at our holiday house and we wanted the same inverter (just to make monitoring easier). They were competitively priced and very adaptable with the installation and connections. Our Victorian triple storey house provide some problems for connecting the panels to the inverter and switchboard. But these guys handled the issues extremely well and kept informed at all times.Importantly they finished the job neatly, no extra costs and the system has been working a treat.
We are very happy.

Highly recommended Mahoney & Da Silva
Dave and the team were fantastic to deal with. Dave's knowledge and experience was obvious. He patiently answered all my questions and queries during the quoting process. The installation was really fast, smooth and with minimal disruption. The installation of the hardware was really neat and tidy and our place was left clean and tidy afterwards. It was very reassuring to deal with Dave - He was the person looking at our property, discussing our needs and quoting us and then he was the tradesman who installed the equipment. I highly recommend this installer to anyone.Panel rating: 5/5

Spot on Solar Sparkies
From the moment they arrived to give us a quote to the day they installed the solar panels, Evan and David were friendly, understanding of our needs and their recommendations were spot on.They were very reasonably priced, did exactly what they said they would do and were polite, punctual and reliable. They took pride and care in what they did and were quite knowledgeable in the solar panels and batteries. I had a very good experience and would recommend them in a heartbeat.
