Customer Reviews

Justin Wong

Had a great experience overall with Guelph Solar. Very good communications throughout the whole process. Misha was great to work with and answered any questions I had. The project team worked as quickly as they could through the different weather conditions and I am happy with the final results. Definitely recommended if you're thinking of going solar!

Jonathan Puddle

Researched lots of options and chose Guelph Solar based on their expertise and pricing. Even a competitor said, "Oh yeah, you're in good hands." when I told them who we had chosen to go with. Rooftop install was done in 2 days, and the workmanship was excellent. Electrical work takes a bit longer but depends on others (like the city utlities, etc.) We're very satisfied with the experience and would recommend them to everyone.

Tom Kavassalis

After doing our diligent research and considering several options, we ended up going with Guelph Solar (GS). GS was very responsive to our needs and were willing to accommodate preferences we had. They were also willing to travel to the site, which is quite far from Guelph to ensure that they can prepare the best possible proposal for us. The work performed by the panel installers was very neat and tidy. Likewise, the electricians wrapped things up with the same care and attention to details. Overall, the transaction was very smooth, uncomplicated and the work was completed well within the timeframe laid out at the beginning of the product. From Sales, through Technical to Billing, GS was very easy to deal with. I highly recommend them.

Guelph Solar did a great job for us, from Mike meeting with us, answering our questions, and guiding us through the process, to the team who did the installation and got everything hooked up. It was fast, efficient and very professional.

If you’re looking for a company that conducts themselves with excellence, Guelph Solar is shockingly good! From start to finish, they charged ahead with top-tier service, making the whole process current-ly the best experience I could ask for. The team was wired for success — professional, friendly, and clearly amp-lified by their passion for renewable energy. They didn’t leave me in the dark once, always keeping communication bright and clear. Installation was a spark of genius, and now my system is running so smoothly, it’s practically electrifying. If you want a company that truly resonates with quality and care, Guelph Solar is the bright choice. Thanks for powering up my home and my faith in great local businesses!
