This document summarizes a seminar presentation on solar roadways. It describes the key features of solar roadways, including three layers consisting of a glass road surface, electronics layer, and base plate layer. The presentation outlines advantages such as renewable energy generation, road illumination, intelligent transportation systems, and electric vehicle charging. Disadvantages include high initial costs and potential issues with maintenance and seasonal efficiency. The conclusion states that solar roadways could provide a renewable alternative to traditional asphalt roads and power generation if implemented on a large scale.

4. 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.

5. 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.

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

7. 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.

8. 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.

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

11. 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.

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.

Life-span – 20-21 years
Road Illumination
Intelligent Highway system
Military and rescue assistance

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

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

15. 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.
