We had an excellent experience with Guelph Solar for our residential solar panel installation. The team was very knowledgeable, helpful, and reliable from start to finish. The installation team was professional, helpful and skilled. Highly recommended! After doing our diligent research and considering several options, we ended up going with Guelph Solar (GS). GS was very responsive to our needs. They were also willing to travel to the site, which is quite far from Guelph. The work performed by the installers was very neat and tidy.
