About Us

Great Canadian Solar Ltd. (GCS) is a 100% Alberta owned electrical engineering and contracting company specializing in the installation of grid connected and grid isolation photovoltaic (PV) power systems.  

GCS is based in Edmonton and services all of Western Canada.

The company was originally incorporated as C.T's Electrical Consulting and Construction in 2005. Until 2009, we focused on commercial/residential electrical installations and industrial electrical design services to engineering companies.

In 2009, GCS's focus switched to the design, procurement and construction of grid connected and grid isolated photovoltaic (PV) power systems for residential, agricultural, commercial and industrial clients.  

Since then, GCS constructed 33% of the installed solar capacity within the province and as such, gained valuable experience by installing over 7,000 kW of solar PV systems with no safety incidents.

Since 2009, GCS has consistently proven itself to be a leader in the solar industry by being involved in many of the largest and more difficult projects in the province.

""As a new program exploring alternative energies we realized quickly that a solar photovoltaic teaching array would be an absolute must......After a number of concept changes and a failed attempt at installation it was decided, based on the recommendations of industry insiders, that Great Canadian Solar would take the lead on the project. We haven’t looked back since....They have proven themselves to not only be master technicians but excellent role models for our students. Many thanks to the team at GCS.""
