Wilson Electric

Wilson Electric has a 35-year track record of delivering high-quality installations and systems to commercial clients across Arizona, USA. Through their focus on customer service they have become the largest electrical contractor in Arizona — a state that is becoming a center for the American solar industry.


As part of its research into delivering better products to its customers, Wilson installed Solar Frontier CIS modules on the roof of their corporate headquarters in Tempe, Arizona. The resulting data has allowed them to compare the bene ts of CIS technology to conventional silicon panels. The engineers at Wilson have been favorably impressed.


The inherent nature of CIS panels to deliver higher output than nameplate capacity (the “light soaking” effect) enables Solar Frontier’s panels to provide more kilowatt hours per kilowatt than the competition, even against industry-leading polysilicon panels. It’s qualities such as these that make CIS an ideal choice for high-sunlight applications in intense irradiation environments such as Arizona.
