Implementation of dual-axis solar tracker system for cubesat / Muhammad Syahfri Abdullah

Abstract Dalam tesis ini, prototaip makmal untuk sistem penjejakan solar paksi dua sedang dibuat dan dibentuk untuk meningkatkan prestasi panel suria, terutama untuk CubeSat. Teori kerja mekanisme ini adalah bahawa modul fotovoltaik terus dipadankan dengan cahaya matahari sebanyak 90 darjah, yang memaksimumkan cahaya matahari yang terdedah pada panel suria. Ia membolehkan panel solar menghasilkan lebih banyak elektrik. Dalam kombinasi dengan mikrokontroler ATmega32 dan perisian Arduino (IDE), perintang penginderaan cahaya digunakan untuk mencari cahaya matahari yang dimaksimumkan. Pemasangan dan reka bentuk sistem menjadi subjek sistem suria. Sistem ini menggunakan mikrokontroler ATmega32 dalam sistem Arduino Uno untuk memantau pergerakan dua servomotor yang memutar mekanisme pada dua sudut. Kuantiti putaran dikira melalui pengekodan mikrokontroler berdasarkan maklum balas empat sensor pada kedua-dua hujungnya. CubeSat telah membina dan memasang sistem penjejakan suria pada akhir misi ini. Cahaya matahari dan sumber cahaya kuat lain mungkin dipadankan beberapa kali dengan panel solar. Petunjuk dan titik permulaan lain bagi pengembangan teknologi canggih di masa depan adalah pembinaan sistem suria ini, terutama dalam industri aeroangkasa. _______________________________________________________________________________________________________ In this thesis a laboratory prototype for the dual-axis solar tracker has been created, developed and established to improve performance of solar panels, particularly for CubeSat. The mechanism's working theory is that the photovoltaic modules are continuously matched to sunlight by 90 degrees, which maximises exposed sunlight on the solar panel. It allows the solar panel to produce more electricity. In combination with the ATmega32 microcontroller and Arduino software (IDE), the light-sensing resistor is used to find maximised sunlight. Installation and system design became the subject of the solar system. The system uses an ATmega32 microcontroller in Arduino Uno system to monitor the movement of the two servomotors whose rotate the mechanism at two angles. The quantity of rotation is calculated via the coding of the microcontroller based on feedback of four sensors on either end. CubeSat has built and installed a solar tracking system at the end of this mission. The sunlight and other strong light sources may be matched several times with the solar panel. Another indication and starting point for the future development of advanced technology in the construction of this solar system, especially in the aerospace industry.
