3. INTRODUCTION
• Hearing the concerns about global warming and
knowing our dependency on fossil fuels the solar
roadways imagined to develop roadways with solar
panels.
• Solar roadways technology will replace all current
petroleum-based asphalt roads, parking lots, and
driveways.
• Solar Roadways system would might at present, cost
about three times what it costs to install an asphalt
road.
• Important element of the Solar Roadways
technology is that its power-generation capacity
demonstrates the base load viability of renewable
energy sources.

Solar Roadways –
Rebuilding our
Infrastructure and
Economy
- Alark A Kulkarni
tried to replace all current
petroleum-based asphalt roads,
parking lots, and driveways
with solar roadways technology.
He showed that solar roadways
will create the clean energy
boom and provide a
decentralized, secure,
intelligent, self-healing power
grid which pays for itself.

Innovative
Pavement Design:
Are Solar Roads
Feasible?
- Andrew
Northmore.
Has done research on existing
pavement materials and tried to
replace a existing pavement
materials with solar panels. He
has discussed in this paper
about, how such a road panel can
be constructed and
manufactured and also the
design of each layer of the solar
road panel, how the panel can be
integrated with photovoltaic
electronics, how such a design
can be weatherproofed, and how
to optimize between solar
capture area and structural
integrity

8. WHAT IS SOLAR ENERGY?
Solar energy is the light and radiant heat from the Sun
that influences Earth's climate and weather and sustains
life. By using this energy electricity can be produced with
help of solar technology.
Solar technologies are broadly characterized as:
Active solar technology
Passive solar technology

9. Photovoltaic cells are used to convert solar
energy directly into electricity using
semiconductors . This is active type of solar
technology.
9

10. Solar energy is preferable as compared to another energy
sources due to following reasons
Reduced Dependence on Fossil Fuels
Environment friendly
Matching Peak Time Output with Peak Time Demand
Flexible Locations
10

11. A solar roadway is a road surface that generates electricity
by solar power photovoltaic cells embedded below a tough
transparent surface which provides sufficient traction.
11

12. A solar roadway consist of three layers:
Road surface layer/Glass layer
Electronics layer
Base plate layer
12

13. Translucent and high-strength, it is rough enough to provide
sufficient traction, yet still passes sunlight through to the solar
collector cells embedded within, along with LEDs and a heating
element.
13

14. It contains photovoltaic cells which absorbs solar energy. It
also contains a microprocessor board with support circuitry
for sensing loads on the surface and controlling a heating
element with a view to reducing or eliminating snow.
14

15. While the electronics layer collects energy from the sun, it is
the base plate layer that distributes that power as well as
data signals (phone, TV, internet, etc.) down the line to all
homes and businesses connected to the solar roadway. It
needs to be weatherproof to protect the electronics layer
above it.
15

16. The power lines and data lines running over the poles,
Make the city ugly, Interrupt to the way of vehicles
Need a frequent maintenance when bad atmosphere tends to break
them
Increase the overall cost as they needs poles to run over
Hacking of trees is required when they come in the way of lines
16

17. This can be avoided by encasing these power lines below the Glass layer which can be
directly supplied by electricity form there itself with no loss of energy due to electric
resistance. This will eliminate all the drawbacks of ‘power lines hung on poles’ and also
ensure safety.
17

18. Many people driving their vehicle at night cannot see the
road ahead due to oncoming headlights or rain.
The Solar Roadways will have LEDs which will
illuminate the lanes.
Thus the rate of accidents will be reduced and
illumination of roads will add to the aesthetics of the city.
18

19. The LEDs can be programmed to show the instructions such as - SLOW, STOP,
GO, SPEED LIMIT, etc.

LANE SCAPE DESIGN
• Central control stations will be able to instantly
customize the lanes and words on the panels as like
screen, reducing traffic congestion.

23. WE CAN SAVE ANIMALS
 The LEDS can also be programmed to warn drivers of an
animal on the road, an accident, or construction work.

24. With induction plating embedded inside these roads, electric
cars can be recharged while in motion on top of these roads.
This would reduce the costs and the time-inconvenience of
waiting at a charging station.
Induction plating Glass panel
Another option available for charging
is stand-by charging which is done by
plugging in the charger in the slot
vehicle, this method can be applied
when the vehicle is parked in the
parking lot.

25. India has a road network of over 48,65,000 kilometers in
2014.
In which national highways and state highways cover 5% 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 10% of total road network of India is
surfaced with Solar Roadway panels, it would illuminate our
nation.
25

26. Renewability
Life-span – 20-21 years
Initial Cost
$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
Road Illumination
Intelligent Highway system
Military and rescue assistance 26

27. Maintenance costs
Seasonal efficiency
Needs a town planning

28. CASE STUDY
28
Solar Roadways™ is a company based in Idaho that is working to perfect
and implement the idea of solar panels embedded within road surfaces,
sidewalks and parking lots. The company was started by Scott and Julie
Brusaw.
 Phase I Prototype:
The United States Department of Transportation awarded the company Solar
Roadways Incorporated a $100,000 research contract in 2009. This Small
Business Innovation Research (SBIR) contract enabled Solar Roadways to
prototype solar road panels. The concept has been used for lighting as well.
 Phase II Prototype:
After successful completion of the Phase I SBIR contract, Solar Roadways Inc.
announced that the Federal Highway Administration awarded it a follow-up
$750,000 Phase II SBIR contract to take it to the next step: a solar parking lot.
The lot was finished in April of 2014. The following pictures are of prototype
II.

32. For roughly the same cost of the current systems (asphalt
roads and fossil fuel burning electricity generation plants), the
Solar Roadways can be implemented.
No more Global Warming.
Safer driving conditions.
Far less pollution.
A new secure highway infrastructure that pays for itself.
A decentralized, self-healing, secure power grid.
No more dependency on foreign oil.

33. • Our Hon’ble Prime minister Narendra Modi has made
promise to built 100 smart cities across the nation. If
we provide solar roadways in those 100 smart cities, we
can at least overcome the problem of load shedding.
So let’s start with 100 smart cities.
