Actual sun position determination for smart solar panels orientation management

The paper presents a technical solution for actual sun position determination that is used for smart solar panels orientation. The system is comprised of multiple sensor units, real-time clock module, motor control DAC module and wireless RF module. The signals from the photodiodes and the mathematical calculations based on the RTC system data, along with the solar panel temperature and sun radiation measurements as feedback for the system, form together a data stack which is used for the development of an algorithm for intelligent solar panel orientation management.
