Flexible single-axis tracker design

The Sunflower II, from RBI Solar, is the second iteration of RBI Solar's Sunflower single-axis tracker design, which utilizes a gearbox design at each pile to reduce stresses and provide tracking stability at each foundation. This engineering feature allows for lighter components to be used in the structure's design, making for a simplified installation in the field. The flexibility of the system's design also allows for complete layout optimization. Sunflower II can accommodate any grade changes up to 15%, which can significantly reduce the amount of civil scope and site preparation time prior to construction. The drivetrain system connects the gearboxes at the top of each foundation and carries the power from the motor to rotate PV modules throughout the day. The drivetrain has been engineered to operate on undulating topography. Each row of the Sunflower II system operates independently, so software upgrades to the communications and controls systems ensures every row is rotating in conjunction with one another. These enhancements increase the reliability of backtracking, operational uptime, and system performance. RBI Solar has dedicated project managers and certified installation teams that are capable of ensuring each Sunflower II system is properly installed and commissioned. Their installation crews are required to complete mandatory training and must follow QA/QC protocols in order to install the Sunflower II system. Along with the complete mounting system, the Sunflower II is equipped with an integrated electronic balance of systems (eBos) that ranges from wiring to combiner boxes.
