Design and Production for Automatic Tracking System of Portable Solar Panel
2019
Due to the rapid development of field operation, camping, exploration, or any other situation, most people require a short-term electric power supply. Therefore, solar power generation gets approved gradually. The angle between the panel and the solar angle of incidence play a decisive role in generating the efficiency of the solar panel. When the angle of incidence reaches 90 degree, the generating efficiency of the panel can also reach as high as 90%, whereas when the angle of incidence reaches 70 degree, the generating efficiency only gets 40% with quick decrease. In this present study, we introduced a mechanical structure, easy to assemble, dismantle and deliver, which is used for the relationship between the Earth and Sun movement. The hardware bracket and control software of the solar panel automatic tracking system consisted of HX4040W-8 aluminum profile, 200 W SUN-L single crystal solar panel and Singfo 1500W solar power generation system, large torque 86 stepping motor with 12.8 n.m static torque, driver dm860, STC12C5A60S2 single-chip and 1602A LCD. The results of electric power graph showed that the value measured by an automatic tracking system between 10:00 and 14:00 is significantly higher than the value of the fixed device.
