This paper introduces a design and realization of low cost solar tracking system with smart monitoring system for electrical and tracking performance data. Microcontroller Arduino was used as a main controller unit for the proposed system. Two Servo Motors (SMs) have been used to move the solar panel (horizontally and vertically) at maximum light source location sensing by Light Dependent Resistors (LDRs).Thus, the solar panel will take maximum absorption of the light from the sun that necessary to produce the maximum amount of electrical power and obtaining relatively high efficiency compared to the fixed position solar system. Real-time monitoring of the PV panel characteristics (voltage, current and power consumption) was accomplished using only one sensor for current (ACS712 current sensor), and voltage divider circuit. These data in addition to the angles of the two SMs are displayed on LCD. A Bluetooth module HC-05 is used to transmit the measuring data from Arduino to the mobile device. Proteus software program was used as a Simulink environment for simulation the system before practical implementation. The performance of the proposed system has been tested at different time periods, and it shows the efficiency of the dual tracking system is more than efficiency in fixed system solar panel (at optimum angle that pre-calculated).

W artykule zaprezentowano prosty i tani system śledzenia słońca. Dwa serwomechanzmy przemieszczają panel słoneczny tak aby otrzymał maksimum światła. Dane mogą być przesyłane do urządzenia mobilnego.
