The document discusses the benefits of using a solar panel that can track the sun compared to stationary panels. It notes that tracking panels can increase energy production by 30% by keeping the panel perpendicular to the sun. However, sun tracking panels are not widely used due to their higher initial costs and need for maintenance. The document then describes the specific sun tracking panel design, which uses light sensors, a dual-axis system, micro servos, and an Arduino computer program to actively track the sun's movement and maximize energy absorption from the solar cells.

1. SUN TRACKING SOLAR
PANEL

2. UNDERSTANDING THE
PROBLEM
• Efficiency of
our current solar
cell is 18-20%.
• Better than 3-6%
efficiency that
most green plants
end up with.

3. SOLUTION
1.Improve the
efficiency of
solar panels.
2.Find ways of
getting more
from our
current solar

4. WHY TRACK SUN ?
• The solar panel that tracks sun create 30%
more energy per day than a fixed panel.
• The most energy is absorbed when a surface’s
face is perpendicular to the sun.
• Stationary mounted PV panels are only
perpendicular to the sun once a day.

5. With that kind of
power increase
you would think
everyone would
be doing it, but
it is not the
case....

6. WHY IT IS NOT
OVERLY COMMON?
• Initial cost of setup
is higher since it
requires moving
parts.
• It also requires
maintenance.
• You would need to
power this equipment
in order to keep it

7. ACTIVE TRACKING
• Our tracker is an
active tracker which
is controlled by a
computer
program(via an
ardunio).
• This means that we
use sensors to find

8. LIGHT DETECTING
RESISTOR
• For sensors, we are
using four light
sensitive (detecting)
resistors, also known
as LDRs.
• They work by
changing their
resistance level on

9. DUAL AXIS
• It tracks in both X
and Y i.e. it goes
left, right, up and
down.
• Once you have your
tracker set up you
will never need to
change or adjust
anything.

10. SERVOS MOTOR
• We are using two “micro” servos in the 9g
size.
