چکیده

During recent years solar energy has been the most important renewable energy. Due to the Earth’s rotation, the Sun rises and falls every day and its illumination angle changes continuously. PV systems equipped with solar tracker keeping solar cells directly facing the sun in real time is the best way to ensure the highest photoelectric conversion efficiency. In this paper a solar tracker system is proposed to increase efficiency and the ability of absorbing solarradiation of the photovoltaic module. An automatic designed system consists of GPS module, accelerometer for angle measurement, and a microcontroller which is responsible for the equipment management. The processing and control unit receives the current angle (feedback signal) and compare it to the desired angle from the database. If the difference between the feedback signal and the database angle is not zero, then the proposed system operates and fixes panels in optimum angle.

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
