The document discusses the concept of solar roadways, first proposed in 2009 and aimed at replacing conventional asphalt roads with solar panel roads to harness solar energy. It outlines the construction, working principles, advantages, and future potential of solar road technology, highlighting benefits such as illuminated lanes, electric vehicle charging capabilities, and self-heating systems for snow management. Despite high initial costs, the document concludes that solar roads can become a sustainable choice for energy and transportation in the future.

3. INVENTORS OF SOLAR ROADWAYS
Julie & Scott Brusaw

4. INTRODUCTION
 In 2009, the innovative idea of Solar Panel Roads was
proposed.
 In 2010, company named SOLAR ROADWAYS was
established.
 Location : Idaho, US.
 Funded by US federal government.
 Aim : to replace current asphalt roads with solar panel
roads.

5. The idea is to replace all current
petroleum based asphalt roads, parking
lots, and driveways with Solar Road
Panels that collect energy to be used by
our homes and businesses.
The ultimate goal is to store excess
energy in or along-side the Solar
Roadways.

6. Solar Road Construction
PHOTOVOLTAIC CELL
 Photovoltaic cells are used to
convert solar energy directly
into electricity using
semiconductors. This is the
active type of solar
technology

8. Road consists of 3 layers.
I. Road Surface Layer
II. Electronics Layer
III. Base Layer

9. Road Surface Layer
 Translucent and
high-strength.
 Designed for
reduced
skidding
chances
 Weatherproof.

10.  Embedded with
LEDs and a
heating element
 Tested for
traction, load
carrying capacity
& impact
resistance
and exceeded all
requirements

11.  Middle layer.
 Contains photovoltaic cells.
 Conversion of solar energy to
electrical energy takes place
here.
 Houses the heating element
and microprocessors for
controlling them.
 It also houses the
microprocessors for controlling
lighting LEDs.

12. Base Plate layer
 Bottom layer.
 Stores the converted
electrical energy.
 Distributes electrical
energy.
 Made weatherproof.

13. How it Works?

15. ADVANTAGES

16. DISADVANTAGES

17. Features of Solar Roadways
(a) Accident can be avoided
:
 The roadways can protect
wildlife and motorists.
 The load cells in the solar
panels can detect if
something is on the surface
of the panel. It acts like a
weigh machine.

18. (b) Illuminated roads :
 The Solar Roadways will
have LEDs which will
illuminate the lanes. The
LEDs can be programmed
to show the instructions
such as - SLOW, STOP,
GO, SPEED LIMIT, etc.

19. (c) Electric Vehicles
 Electric vehicles are on the
way. More and more car
manufacturers are offering
electrical options
 EVs can be rechargeable at
any convenient located rest
stop or at any parking lots.
 Owners can plug their car in
and recharge while not
driving.

20. (d) Snow/ ICE Management :
 The roads heat
themselves with
their embedded
heating elements
and melt away all
the snow.

21. (e) Improved power lines

22. (f) Intelligent Highways
 Pays for itself
 Telephone, cable TV, and
high-speed internet
 Intercommunication
between road and cars to
avoid collision
 Tracking system
embedded.

23. (g) PARKING LOT INTEGRATION

24. Future Scope
 With the provision of initial investment it can be carried
forward.
 Increased energy requirement in future can only be met
with renewable resources of energy, such as that obtained
from solar roadways.
 To reduce the consumption of fossil fuel and to eliminate
global warming, the innovative idea of solar panel road is
inevitable.

25. COST FOR SOLAR PANEL ROADS
 $16 per square feet – Asphalt road
One panel size 12 ft x 12 ft = 144 sq ft. One panel costs
about $6912
$6912 / 144 sq ft = $48 per sq ft - Solar road

26. CONCLUSION
 Even though the initial cost is high, as it is a system
that pays for itself it is a better choice.
 For under developed and developing countries, it
might seem impractical now. But it can be adopted in
stages, in future.
 With technological upgradation in this field, jobs,
clean energy and a safer transportation system can be
made.
