A wide range photoelectric tracking sensor is proposed and its working principle is introduced. A test platform is set up and the fields of view of altitude and azimuthal angle as well as its tracking accuracy are experimentally studied. The results show that as for this sensor, its field of view of azimuthal angle is -180°-180° and that of altitude is -90°-90°. Thus the requirement of wide response range for sensors is satisfied. In addition, the accurate tracking accuracy is high and the error is ±1.5°, therefore the requirement of tracking accuracy for the solar photovoltaic power generation is also satisfied. This research provides a basis for the development and use of solar tracking photoelectric sensors.
