Introduction:

Solar panel is the conversion of sunlight energy into electricity.

Photovoltaic convert light into electric current.

Solar panel

BLOCK DIAGRAM:

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.

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.

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

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

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

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.

CIRCUIT DIGRAM

AFTER DESIGNING:

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)

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.

• 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.

FUTURE PROSPECTS:

Improve Solar Panels.

Reduce Weight.

To Improve Reliability.

To Reduce The Cost.
