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

wanted to implement a few modern technologies in USA, which have been unified to create a better, safer, more profitable, environmentally friendly, and energy producing solution, because United States of America has many proud characteristics: free, powerful, wealthy, and innovative.

WHAT IS SOLAR ENERGY?

Solar energy is the light and radiant heat from the Sunthat influences Earth's climate and weather and sustainslife. By using this energy electricity can be produced withhelp of solar technology.

Solar technologies are broadly characterized as:

Active solar technology

Passive solar technology

Photovoltaic cells are used to convert solarenergy directly into electricity usingsemiconductors . This is active type of solartechnology.

9

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

A solar roadway is a road surface that generates electricityby solar power photovoltaic cells embedded below a tough

transparent surface which provides sufficient traction.

11

A solar roadway consist of three layers:Road surface layer/Glass layerElectronics layerBase plate layer

12

Translucent and high-strength, it is rough enough to providesufficient traction, yet still passes sunlight through to the solarcollector cells embedded within, along with LEDs and a heatingelement.

13

It contains photovoltaic cells which absorbs solar energy. Italso contains a microprocessor board with support circuitryfor sensing loads on the surface and controlling a heatingelement with a view to reducing or eliminating snow.

14

While the electronics layer collects energy from the sun, it isthe base plate layer that distributes that power as well asdata signals (phone, TV, internet, etc.) down the line to allhomes and businesses connected to the solar roadway. Itneeds to be weatherproof to protect the electronics layerabove it.

15

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

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

Many people driving their vehicle at night cannot see theroad ahead due to oncoming headlights or rain.

The Solar Roadways will have LEDs which willilluminate the lanes.

Thus the rate of accidents will be reduced andillumination of roads will add to the aesthetics of the city.

18

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.

WE CAN SAVE ANIMALS

The LEDS can also be programmed to warn drivers of ananimal on the road, an accident, or construction work.

23

With induction plating embedded inside these roads, electriccars can be recharged while in motion on top of these roads.This would reduce the costs and the time-inconvenience ofwaiting at a charging station.

Glass panelInduction plating

Another option available for chargingis stand-by charging which is done byplugging in the charger in the slotvehicle, this method can be appliedwhen the vehicle is parked in theparking lot.

24

India has a road network of over 48,65,000 kilometers in2014.

In which national highways and state highways cover 5% oftotal road network.

These highways can produce 450TWh of electricity accordingto 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 issurfaced with Solar Roadway panels, it would illuminate ournation.

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.

For roughly the same cost of the current systems (asphaltroads and fossil fuel burning electricity generation plants), theSolar 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.

• 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.
