Sensorless and Power-Optimized Sun Tracking for CPV Applications Using Dual-Axis Trackers

摘要

Tracking mismatches can cause severe power drops and energy losses in a CPV system. Also, classical open-loop and closed-loop position controllers do not take the generator's output power into account. Therefore, a new sensorless and power-optimized dual-axis CPV tracking controller has been developed and is presented here.
