sun tracking system design two axis pdf

[Guest]

The main objective of this project is to track the sun and rotate the solar
panel accordingly to receive sunlight up to maximum extent always during the day time.

This movement is achieved by interfacing a stepper motor to the solar panel that changes
its direction according to the positioning of the sun. This is achieved using time reference
that controls the movement time for 12 hours by a program written in such a way that
for every given time the solar panel faces to the sun to generate maximum power which
is stored in batteries and future use. This procedure is better than light sensing, as it
malfunctions in cloudy and rainy seasons.
