At 177 years-old Simons may be one of the oldest retailers in Canada, but its new Edmonton store has the largest solar system in the city. Standing on top of the new Simons at Londonderry Mall I am surrounded by a sea of 996 solar modules and below in the parking lot I have a birds-eye view of 720 more solar modules on two solar car ports. The solar system is 636 kilowatts, the largest in Edmonton and enough to provide Simons new 90,000 square foot store with half of it’s electricity.
