WHAT IS SOLAR ENERGY?

Solar energy is the light and radiant heat from the sun that

influences earth’s climate and weather that sustains life.

This energy can be used for the process of generation of

electricity by tapping the solar energy.

Solar technologies are broadly characterized as

1. active solar technology

2. passive solar technology

5

Photo voltaic cell

Photo voltaic cell are used to convert solar energy directly into electricity using semi conductors. This is active type of solar technology.

6

Why solar?

Solar energy is preferable as compared to another

energy sources due to the following reasons:

Reduced dependence on fossil fuel

Environment friendly

Matching peak time output with peak timedemand

Modularity and scalability

Flexible locations

7

Existing problem in road construction

Made with petrochemical product called

asphalt. This is a nonrenewable product.

Deposition of ice

Needs to be painted with information.

Huge cost for repairs

What does solar roadway means?

A solar roadway is a road surface that generates electricity by solar power using photovoltaic and includes solar panels and LED signage, that can be driven on.

How it Works?

Sunlight falls on solar panels which

generates electricity

This is as same time is transferred to

nearby houses and power station

LEDs controlled by microprocessors display

information on the surface of road

Anti icing layer clears the road

Also senses changes in weight

Solar Road Construction

A solar roadway consists of three layers: Road surface layer/Glass layer Electronics layer Base plate layer

ADVANTAGES

Renewability Life-span Road illumination Intelligent highway system Military and rescue system Smart grid Traffic assistance Driver assistance Oil independence

16

Road illumination

Real time information can be displayed on road itself.

Works as drivers personal assistance.

LEDs could warn drivers if they exceed speed limits or drive too slow.

17

Intelligent highway system

Pays for itself Telephone, cable TV and high

speed internet Inter communication between

roads and cars to avoid collision Tracking system embedded

18

Military and rescue system

In the event of an environmental disaster or

military emergency, solar roadways would provide

power when it is needed most.

As solar power is renewable, it obviously requires

no external connection to an artificial power

source should provide power when it is needed

most.

On the go charging

20

Smart grid

Removes the needs of grids, directly

transfers electricity.

No overhead wiring and poles

required

Also has telephones cable TV and high

speed internet optics laid down.

21

DISADVANTAGES

High initial cost

Road surfaces deposits reduces its efficiency( salt,

rubber and dirt)

Seasonal efficiency.

Needs a town planning.

22

Road survey of India

India had a road network of over 42,45,805 kilometers in 2011.

In which national highways and state high ways cover 0.05%of total road network.

These highways can produce 4500TWh of electricity according to references when they are surfaced by solar panels

But India needs 991TWh of electricity This implies that if 0.01% of total road network of

India is surfaced with solar roadway panels, it would illuminate our nation.

23

Conclusion

For roughly the same cost of the current system (asphalt roads and fossil fuels burning electricity generation plants), the solar road ways can be implemented.

No more global warming. Safer driving conditions. Far less pollution. A new secure high way infrastructure that pays for

itself A decentralized self healing secure power grid, No more dependency on foreign fuel.
