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
6
Photo voltaic cellPhoto voltaic cell are used to convert solar energy directly into
electricity using semi conductors. This is active type of solar technology.
7
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
8
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.
9
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
10
Solar Road Construction
A solar roadway consists of three layers: Road surface layer/Glass layer Electronics layer Base plate layer

14
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
15
ADVANTAGES
Renewability Life span Initial cost Road illumination Intelligent highway system Military and rescue system Smart always connected roads and
vehicles 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.

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
Traffic assistance
Each panel has a microprocessor that monitors the
load above it. With embedded GPS it could itself evaluate the
alternate routes. Better traffic management thus further decreasing
pollution. Warns drivers for sudden change in weight on roads.
22
DISADVANTAGES
High initial cost Road surfaces deposits reduces its efficiency( salt,
rubber and dirt) Seasonal efficiency. Needs a town planning.
23
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 450TWh 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.
24
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.
