6. Solar panel
BLOCK DIAGRAM:

7. Solar panel:
• A solar panel is a packaged, interconnected assembly of solar
cells, also known as photovoltaic cells.
• The solar panel can be used as a component of a larger
photovoltaic system to generate and supply electricity.
• A photovoltaic system typically includes an array of solar
panels, an inverter, battery and interconnection wiring.

8. How much electricity do we
use?
• A typical Indian home uses about 1 kW of power, or about 24
kWh per day
• If we average over everything – homes, factories, schools, etc.
we use about 37 kWh per day for each person.

10. MOTOR DRIVE:
 Here we used H-BRIDGE to drive the motors, whatever
signals it receives from the microcontroller on the basis of
that it will drive the motors.
 An H-BRIDGE is an electronic circuit which enables a
voltage to be applied across a load in either direction.
 H-BRIDGES are available as integrated circuits, or can be
built from discrete components

11. Rechargeable battery:
 Solar cars use a range of batteries including
• Lead-acid batteries,
• nickel-metal hydride batteries (NiMH),
• Nickel-Cadmium batteries (NiCd),
• Lithium acid batteries
• lithium polymer batteries without any pollution.
 A rechargeable battery or storage battery is a group of one or
more electrochemical cells.
 Rechargeable batteries come in many different shapes and sizes, ranging
anything from a button cell to megawatt systems connected to stabilize an
electrical distribution network

12. SENSOR:
 In this project we use infra red led and photodiode to check
the interruption
 Infra red led transmits the rays in the air and these rays are
reflected back by the surface and focus on the photodiode
 photodiode provide a signal to the controller and controller
change the direction of the solar car automatically

13. DC MOTOR:
Electric motor, operation is based on simple electromagnetism.
A current-carrying conductor generates a magnetic field.
The internal configuration of a DC motor is designed to harness
the magnetic interaction between a current-carrying conductor
and an external magnetic field to generate rotational motion.

14. CIRCUIT DIGRAM

15. AFTER DESIGNING:

16. Microcontroller:
We use I.C 89s2051 as a main processor to control all the
sensor’s and output motor’s.
The at89c2051 is a low-voltage
High-performance CMOS 8-bit microcomputer with 2 Kbytes
of flash programmable
Program erasable read only memory (PEROM)

17. Advantage’s of project:
• Solar energy is a completely renewable resource.
• Oil, which is what most people currently use to power their
homes, is not a renewable resource. This means that as soon
as the oil is gone, it is gone forever and we will no longer have
power or energy.
• Solar cells make absolutely no noise at all.

18. • 4. Solar energy creates absolutely no pollution.
• 5. Very little maintenance is required to keep solar cells
running.
• 6. Solar panels and solar lighting may seem quite
expensive when you first purchase it, but in the long run
• 7. Solar powered panels and products are typically
extremely easy to install.
• 8. Solar power technology is improving consistently over
time.

19. FUTURE PROSPECTS:
Improve Solar Panels.
Reduce Weight.
To Improve Reliability.
To Reduce The Cost.
