Abstract

As China promotes the development of new energy, the solar energy project is one focus of the country. Due to the imperfection of photoelectric and mechanical solar tracking and positioning technology steps, this paper will introduce an intelligent solar photovoltaic tracking device based on an STM32 processor with ARM Cortex-M as the core. The operating principle of the device is that it will determine the rotation direction and rotation angle of the panel around the vertical and horizontal axes based on the voltage output generated by the photoresistor detection of light and have two stepper motor drivers run the dual-axis automatic solar tracking system to complete the operation of the whole system.
