Named for its ability to concentrate the sun’s energy by 7 times, the SunPower® C7 Tracker delivers the lowest levelized cost of electricity (LCOE) for utility-scale deployment available today. The SunPower C7 Tracker combines a horizontal single-axis tracker with rows of parabolic mirrors, reflecting light onto the world’s highest-efficiency silicon solar cells powered by the unique, patented SunPower® Maxeon® cell technology. This record-breaking concentrated photovoltaic (CPV) tracker solution is based on SunPower’s ten years of experience in PV power plant trackers, with over 700 MW of tracker systems installed globally. Reliability and energy production are industry-leading with SunPower Maxeon cell technology; highest efficiency solar backed by proven experience in deploying over 2.5GW of PV around the world.
The SunPower C7 Tracker has been designed from the ground-up for gigawatt scale deployment. Manufacturing can be quickly established in proximity to power plants enabling rapid installation and local economic development. The C7 Tracker components are factory preassembled enabling rapid installation using standard tools and requiring no specialized field expertise.
