IntroductionA 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.

Problems with existing roads

• Made with petrochemical product asphalt. This is a nonrenewable product.

• Deposition of ice.• Needs to be painted

with information.• Huge cost for repairs.

How it works.

6

Working

• Sunlight falls on solar panels which generates electricity.

• This at same time is transferred to nearby houses and power stations.

• LEDs controlled by microprocessors display information on the surface of road.

• Anti Icing layer clears the road.• Also senses changes in weight.

Construction of Solar Roadway Panel

Layers

9

Solar Roadway panel is made up of three layers:• Road Surface Layer• Electronics Layer• Base Plate Layer

Road Surface Layer

• Translucent and high-strength.

• Rough enough to provide great traction

• Embedded with LEDs and a heating element.

• Weatherproof.10

Electronics Layer

• Solar Panels• Contains a

microprocessor board with support circuitry.

• Senses loads on the surface and controls the heating element.

• A communications device every 12 feet.

11

Base Plate Layer

• Distributes power and signals to and from the panels.

• Waterproof for protecting the electronics layer.

12Base Plate Layer

Challenges

Making a glass which is:– Same traction as

asphalt road.– Strong enough to

support traffic.– Shatter proof.– Fireproof.– Anti – Glare to avoid

reflection on driver’s eyes.

13

Advantages

• Intelligent Highways• Illuminated Roads• Smart always connected roads and vehicles• Smart Grid• Oil Independence

14

Intelligent Highways

• Pays for itself• Telephone, cable TV,

and high-speed internet• Intercommunication

between road and cars to avoid collision

• Tracking system embedded.

15

Illuminated Roads

• Real time information can be displayed on road itself.

• Works as drivers personal assistance.• LEDs could warn drivers if they exceed

speed limits or drive too slow.16

Oil Independence

• Generates its own electricity which could be used for all purposes.

• By using charging stations electrical cars could have same advantage as IC engine for distance.

• Fix price security.• Contributes towards a

greener tomorrow.17

Smart Grid

• Removes the need of grids, directly transfers electricity.

• No overhead wiring and poles required.

• Also has telephones, cable TV and high speed internet optics layed down.

18

Traffic Assistance

• Each panel has a microprocessor that monitors the load above it.

• With embedded GPS it could itself evaluate the alternate route.

• Better traffic management thus further decreasing pollution.

19

Drivers assistance

20Warns drivers for sudden change in weight on roads.

Disadvantages

• High initial cost.• Road surfaces

deposits salt, rubber and dirt, which reduces its efficiency.

21

Conclusion

• To this we conclude that definitely present roadways can be replaced by the solar roadways but huge initial investment requires.
