1. The document discusses the concept of solar roadways, which involves embedding solar panels into road surfaces to generate electricity. The solar roadways would be made up of three layers - a glass surface layer, an electronics layer containing photovoltaic cells, and a base plate layer to distribute power. 2. In addition to power generation, the solar panels could be programmed to provide instructions to drivers using LEDs for safety and traffic control. The embedded heating elements in the panels could also melt snow and ice, reducing road hazards. 3. It is proposed that solar roadways could provide electricity to homes and businesses while requiring similar costs to traditional asphalt roads. This could help reduce fossil fuel usage, pollution,

3. INTRODUCTION
 World facing problem of energy source – demand is not
match supply.
 In order to match – non convention energy sources –
mainly solar energy.
 Solar energy – photovoltaic cells –convert into another
form.
 Solar road ways use to extract solar energy without waste
land

4. Contt…
 Solar roadway is a series of solar panels, structurally
engineer to be driven upon.
 This idea - replace all current petroleum-based asphalt
roads, parking lots, and driveways.
 Collected energy to be used by our homes and businesses.

5. WHY SOLAR ?
 Reduced Dependence on Fossil Fuels
 Environment friendly
 Matching Peak Time Output with Peak Time Demand
 Modularity and Scalability
 Flexible Locations

6. SOLAR ROADWAYS
• It is a road surface that generates electricity.
• Photovoltaic cells embedded below a tough transparent surface
which provides sufficient traction.

7. PHOTOVOLTAIC CELL
• Conversion of light energy into electrical energy called
photovoltaic cell

8. SOLAR ROAD CONSTRUCTION
A solar roadway consist of three layers:
Road surface layer/Glass layer
Electronics layer
Base plate layer
88Fig 4 Layers of solar roadways

9. ROAD SUFACE LAYER
• Top most layers of assembly, solar rays is reach upto the
photovoltaic cells.
• Rough enough to provide great traction to avoid the skidding
of vehicles.
• Embedded with LEDs and a heating element.
99Fig 5 Road surface layer

10. ELECTRONICS LAYER
• It contains photovoltaic cells which absorbs solar energy.
• It contains - microprocessor board with support circuitry for
sensing loads on the surface.
• Controlling a heating element with a view to reducing or
eliminating snow.
• The LEDs can also be programmed – show - speed limit -
warning to the drivers instantly - driving too fast.

12. BASE PLATE LAYER
• Electronics layer collects energy from the sun - base plate
layer - distributes that power.
• 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.

14. INTELLIGENT HIGHWAY
 LEDs is use to show the instructions such as - SLOW, STOP,
GO, SPEED LIMIT, etc.
 The LEDS programmed to warn drivers of an animal on the
road, an accident, or construction work.
 Central control stations instantly customize the lanes and
words on the panels as like screen, reducing traffic.

16. ILLUMINATED ROADWAYS
 People driving their vehicle at night cannot see the road ahead
due to on coming headlights or rain.
 The Solar Roadways will have LEDs which will illuminate the
lanes.
 The rate of accidents will be reduced.
 Illumination of roads will add to the aesthetics of the city.

18. ELECTRIC CARS
• Induction plating embedded inside - roads - electric cars –
recharged - motion on top - roads.
• Reduce the costs and the time-inconvenience of waiting at a
charging station.
• Charging can stand-by charging - plugging in the charger - slot
vehicle
• Charging can while vehicle is parked in the parking lot.

20. SNOW ICE MANAGMENT
 Snow on roads, It makes driving dangerous.
Asphalt roads they get damaged when this snow is melted and
increases the maintenance cost.
A Solar Roadway heat themselves with their embedded heating
elements and melt away all the snow.
The panels is used stored energy to stay heated to slightly
above freezing, which would eliminate snow.

26. CONCLUSION
 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.
