The main objective of the project to rotate panel in four direction in two different modes (A) With respect to light intensity and (B) With respect to real time clock. The Direct and undirect sensing two-axis solar tracking system consists of Solar panel, Two DC motors, LDR’s,Motor driver, Switch, RTC module and Arduino Uno. Here we are changing two modes of solar tracking system with the help of switch. We are using four LDR sensors which are placed in four directions of solar panel to track light continuously. Two DC motors are placed under solar panel setup to the movement of solar panel. When there is any cloudy condition like heavy rain or fog we switch into RTC mode to rotate DC motors with respect to time.
