History of our SunPower C&I teams before we welcomed them to TotalEnergies


The evolution of C&I Solutions started with PowerLight Corporation. PowerLight specialized in the design, manufacturing, installation and maintenance of commercial-grade, large-scale and grid-connected solar power systems. On January 10, 2007, PowerLight was acquired by SunPower Corporation, a publicly traded solar company that serves the residential, commercial and utility-scale power plant markets.

 As part of SunPower, we were instrumental in the construction of large-scale projects for top-name brands such as Target, Macy’s, Bed Bath & Body and Walmart. The majority have returned to us as repeat customers to expand their solar portfolios. These ongoing, long-term relationships have allowed us to become one of the most experienced and knowledgeable teams building retail solar rooftops, carports and ground mounts in the United States.

In the public sector, we completed projects for organizations such as the Delaware River Port Authority, the U.S. Armed Forces, Rancho California Water District and the County of Santa Clara, CA.

In the education sector, we have been partnering with colleges, universities and K-12 school districts for 25 years. Customers include Kern High School District, Los Angeles Unified School District, University of California - Davis, California State University, Princeton University and Stanford University.

In 2011, TotalEnergies acquired a majority stake in SunPower, forming a strategic partnership that remains to this day. The partnership led to TotalEnergies’ acquisition of C&I in February 2022 as part of its strategy to expand its distributed generation business.
