What Clients Say About MDS Solar

Our clients choose us because we deliver premium workmanship, honest advice, and energy systems that perform for years. Here’s what real customers have to say about working with Mahoney & Da Silva.

Gerard

The quote process set these guys apart from the rest, an individual site inspection helped choose some alternative products to suit shading, not just a salesman telling you what you want to hear.

Ben Oz

I can’t say enough good things about David and Evan. From the very first consultation, I felt confident that I was in good hands as David was answering each and every detailed question I asked to him. The team was incredibly hardworking, efficient, and genuinely caring about doing the best job possible.

Arnaud Albrecht

Unlike the two big companies that quoted me, David was the only one to actually come to the property and ensure that the install could be done with the right amount of panels. It makes the interaction so much easier and avoids any trouble down the line. Finally they organised the connection to the grid: the inspector, contacting my energy provider and getting all the rebates.

W Wong

From start to finish, Dave and Evan demonstrated the utmost professionalism, guiding us through every step of our solar journey with clarity and patience. We needed a flexible system to which more panels could be added with future renovations. They took the time to listen to our concerns and worked closely with us to find an effective resolution.

Adam Kelly

They did a fantastic job installing our 10.5kw system. I felt 100% confident the money I was spending was well worth it. The workmanship was excellent, even when I was being super picky with the cable routing – nothing was a problem.

Shaun Chong

Very pleased with the 6kW solar system that David and his team proposed. The design and quote was realistic and reasonable, as they did not tend to overpromise unlike other businesses. David has tons of hands on experience being an installer, which gave me confidence.
