I couldn't be happier with the service provided by Keenan Electrical and Solar. Mark and his team were outstanding from start to finish—professional, polite, and incredibly hardworking. They showed up on time every day, worked efficiently, and kept everything tidy throughout the project. What really stood out was their dedication. Rain or shine, they pushed through to make sure the job was completed on time and to a very high standard. The workmanship and attention to detail were excellent, and it’s clear they take real pride in what they do.
I tend to never write any public reviews, but in the case of "Keenan Solar" I really must make an exception, as Mark Keenan and his team have done such a superb job! 5* for design, 5* for execution and 5* for being nice guys too. I am totally happy with the solar installation they built for me; Mark carefully listened to my hopes and aspirations and he and his team have built precisely what I was hoping to get. Yes, it took a few days longer than initially planned, but the heavy heatwave hardly helped, nor did my flat roof and the complications it threw up. "Keenan Solar" have truly mastered the job wonderfully - and cleanly - plus they were always very quick to react to any questions I had along the way. What more can I ask for? I wholeheartedly recommend them!
Five stars here because Mark and his team were quick, efficient and got the job done when they said that they would. The installation was on a house with some awkward architectural features - the walls are as hard as they come. Admittedly in a sunny period, the majority of my generation, 60% in fact, goes back to the grid, although the paperwork for payment is taking a while.
