4. With the unavoidable shortage of fossil fuel sources in the future, renewable types of energy
have become a topic of interest for researchers, technicians, investors and decision makers allaround
the world. New types of energy that are getting attention include hydroelectricity, bioenergy, solar,
wind and geothermal energy, tidal power and wave power. Because of their
renewability, they are considered as favourable replacements for fossil fuel sources. Among
those types of energy, solar photovoltaic (PV) energy is one of the most available resources.
This technology has been adopted more widely for residential use nowadays, thanks to
research and development activities to improve solar cells’ performance and lower the cost.
According to International Energy Agency (IEA), worldwide PV capacity has grown at 49%
per year on average since early 2000s. Solar PV energy is highly expected to become a majorsource of
power in the future
INTRODUCTION

5. • Resistance of LDR depends on intensity of the light and it varies according to
it. The higher is the intensity of light, lower will be the LDR resistance and due
to this the output voltage lowers and when the light intensity is low, higher will
be the LDR resistance and thus higher output voltage is obtained
• A potential divider circuit is used to get the output voltage from the sensors
• (LDRs).The circuit is shown here
WORKING PRINCIPAL
• The LDR senses the analog input in voltages between 0 to 5
volts and provides
• a digital number at the output which generally ranges from 0
to 1023
• Now this will give feedback to the microcontroller using the
arduino software(IDE).
• The servo motor position can be controlled by this mechanism
which is discussed later in the hardware model.

6. BASIC CIRCUIT DIAGRAM
• An overview of the required circuit for the Dual-axes solar tracker is shown here
• The 5V supply is fed from an USB 5V dc voltage source through Arduino Board
• Servo X :Rotates solar panel along X direction
• Servo Y :Rotates solar panel along Y direction

8. FINAL RESULTS
• Dual Axis Solar Tracker project is to provide an efficient solar distributed
generation system. At maximum, the solar tracker is perpendicular to the
light source. The built system has a calculated annual energy gain of
48.982% compared to an immobile solar panel. Compared to a single axis
tracker, the dual-axis tracker has an annual energy gain of 36.504%.
• The purpose of a solar tracker is to accurately determine the position of the
sun. This enables solar panels interfaced to the tracker to obtain the
maximum solar radiation. With this particular solar tracker a closed-loop
system was made consisting of an electrical system and a mechanical
system with the help of electronics.
