This document summarizes a solar panel that tracks the sun like a sunflower to maximize energy absorption. It is composed of a solar panel, servo motor, Arduino board, light sensors, resistors and battery. The tracker uses light sensors and a servo motor to automatically rotate the panel toward the sun throughout the day. This sun-tracking mechanism can increase energy capture by 40% compared to fixed panels and powers applications like drone batteries in a renewable, pollution-free way. The student team's project costs around Rs. 800 and provides benefits like increased energy production and charging of devices.

1. Sun Tracking
Solar Panel

2. Solar Panel:
Photovoltaic solar panels absorb sunlight as
a source of energy to generate direct
current electricity. A photovoltaic module is
a packaged, connected assembly of
photovoltaic solar cells available in different
voltages and wattages. Photovoltaic
modules constitute the photovoltaic array of
a photovoltaic system that generates and
supplies solar electricity in commercial and
residential applications.

3. Working:
Solar-powered photovoltaic (PV) panels
convert the sun's rays into electricity by
exciting electrons in silicon cells using
the photons of light from the sun. This
electricity can then be used to supply
renewable energy to your home or
business

5. “ What Is new in our Project?

6. Inspired By Sunflower

7. Sun Tracking Solar Panel

9. Solar Tracker
A solar tracker is a device
that orients a solar panel
toward the Sun. Trackers are
used to minimize the angle of
incidence between the
incoming sunlight and a
photovoltaic panel.

10. Components:
■ Servo Motor (sg90)
■ Solar panel
■ Arduino Uno
■ LDR’s X 2 (Light Dependent Resistor)
■ 10K resistors X 2
■ Battery (6 to 12V)
Total Cost =
Rs.800

11. Benefits
⊷ Can be able to save
40% more energy
⊷ Renewable Energy
⊷ No pollution

13. Can able to charge the batteries in the flying drones to recharge the
battery :
