Introduction
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.

4. Problems with existing roads
• Made with
petrochemical product
asphalt. This is a
nonrenewable product.
• Deposition of ice.
• Needs to be painted
with information.
• Huge cost for repairs.

6. How it works.

7. Working
• Sunlight falls on solar panels which generates
electricity.
• This at same time is transferred to nearby
houses and power stations.
• LEDs controlled by microprocessors display
information on the surface of road.
• Anti Icing layer clears the road.
• Also senses changes in weight.

9. Layers
9
Solar Roadway panel is
made up of three
layers:
• Road Surface Layer
• Electronics Layer
• Base Plate Layer

10. Road Surface Layer
• Translucent and
high-strength.
• Rough enough to
provide great
traction
• Embedded with
LEDs and a heating
element.
• Weatherproof.
10

11. Electronics Layer
• Solar Panels
• Contains a
microprocessor board
with support circuitry.
• Senses loads on the
surface and controls
the heating element.
• A communications
device every 12 feet.
11

12. Base Plate Layer
• Distributes power and
signals to and from
the panels.
• Waterproof for
protecting the
electronics layer.

Base Plate Layer

13. Challenges
Making a glass which is:
– Same traction as
asphalt road.
– Strong enough to
support traffic.
– Shatter proof.
– Fireproof.
– Anti – Glare to avoid
reflection on driver’s
eyes.

14. Advantages
• Intelligent Highways
• Illuminated Roads
• Smart always connected roads and vehicles
• Smart Grid
• Oil Independence
14

15. Intelligent Highways
• Pays for itself
• Telephone, cable
TV, and high-speed
internet
• Intercommunication
between road and cars
to avoid collision
• Tracking system
embedded.
15

16. Illuminated Roads
• 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.
16

17. Oil Independence
• Generates its own
electricity which could be
used for all purposes.
• By using charging stations
electrical cars could have
same advantage as IC
engine for distance.
• Fix price security.
• Contributes towards a
greener tomorrow.
17

18. Smart Grid
• Removes the need of
grids, directly transfers
electricity.
• No overhead wiring and poles
required.
• Also has telephones, cable TV
and high speed internet optics
layed down.
18

19. Traffic Assistance
• Each panel has a
microprocessor that
monitors the load above
it.
• With embedded GPS it
could itself evaluate the
alternate route.
• Better traffic
management thus further
decreasing pollution.
19

20. Drivers assistance
20
Warns drivers for sudden change in weight on roads.

21. Disadvantages
• High initial cost.
• Road surfaces
deposits
salt, rubber and
dirt, which
reduces its
efficiency.
21

22. Conclusion
• To this we conclude that definitely present
roadways can be replaced by the solar
roadways but huge initial investment requires.
