Solar roadways are innovative road surfaces that generate electricity using photovoltaic panels and LED signage, replacing traditional asphalt roads. While they have high initial costs and maintenance challenges, their advantages include significant renewable energy production, traffic management capabilities, and support for electric vehicles. The technology aims for long-term benefits, including job creation and reduced reliance on fossil fuels, making it a forward-thinking solution for future transportation.

4. 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.

5.  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.

6.  World's first solar panel road opens in
Normandy village, france.
 U.S.’s First Public Solar Road Will Roll Out On
Route 66.

7. FEATURES OF SOLAR ROADWAYS
 Produces more electricity than what is
needed for a country.
(22.96 trillion kilowatt-hours of electricity
per year in US)
 Lighting up of roads with LEDs.
 Provision for snow and ice removal.
 Contributes to traffic rule implementation
and DUI detection.
 Provides a platform for Electric Vehicles.

8. DESIGN OF SOLAR PANEL ROAD
 Solar panel road
consists of three
layers :
 1.Road Surface
Layer.
 2.Electronics
Layer.
 3.Base Plate
Layer.

9. 1. ROAD SURFACE LAYER
 Top most translucent layer.
 Made of extremely durable
textured glass.
 Designed for reduced
skidding chances.
 Waterproof layer.
 Houses the LEDs for
illuminating the roads.

10. 2. ELECTRONICS LAYER
 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.

11. 3.BASE PLATE LAYER
 Bottom layer.
 Stores the converted
electrical energy.
 Distributes electrical
energy.
 Made weatherproof.

12. ADVANTAGES
 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
 Intelligent Highway system

13. DISADVANTAGES
Huge initial cost. (about $ 3.45
trillion is required in US)
Maintenance cost.
Needs a Town Planning.
Skilled Labour Requirement.

14. APPLICATIONS
1.Illuminated Roads
LEDs will paint the road surface from
beneath.
Safe and easy night driving.
2.Electric Vehicles
Recharging stations can be provided along
road side.
Reduces global warming and need for fossil
fuels.

15. ILLUMINATED ROAD AND EV CHARGING

16. PARKING LOT INTEGRATION

17. INTELLIGENT HIGHWAY
 The LEDs can be programmed to show the
instructions such as - SLOW, STOP, GO,
SPEED LIMIT, etc.

18. 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.
