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
9
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
15
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.
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.
