Wind load calculation and testing of dual-axis tracker

Abstract

The technique event condition in the field of solar power plants tracking systems development was analysis. The wind load and the necessary efforts to drive calculated. It is shown that for small installations up to 2 m in diameter is sufficient for standard motors with torque up to 30 Nm. An experimental version of the dual-axis tracker with a DC motor and stepper motor are constructed. Tests have shown that in order to reduce vibration of the best option is the axial position of the motor. To improve the reliability of the system is necessary to choose the DC motors and develop robust PWM controllers.
