Abstract: This paper designed a dual-axis servo solar tracker based on single chip micyoco (SCM). The whole system consisted of minimum system of SCM, position detection circuit, irradiance comparison circuit, clock circuit, keyboard circuit, motor speed regulation circuit and angular position sensor. The software included the calculation of solar altitude and azimuth angle, the main program and each functional module subprograms. The results from debugging and running show that the system is stable, precisely tracking the sun in real time.
Key words: solar energy; tracker; altitude angle; azimuth angle
