CONTENTS

A solar roadways is a road surface that generates electricity by solar power using photovoltaic and includes solar panels and LED signage, that can be driven on.

INTRODUCTION

Solar energy is preferable as compared to another energy sources due to following reasons

Reduced Dependency on Fossil Fuels Environmental friendly Flexible locations

WHY SOLAR ENERGY?

SolarRoadways involves

Photovoltaic effect

PHOTOVOLTAIC CELL

Photovoltaic cells are used to convert solar energy directly into electricity using semiconductors. This is active of solar technology.

A solar roadway consists of three layers: Glass layer/Road surface layer Electronic layer Base plate layer

SOLAR ROAD CONSTRUCTION

Translucent and high strength Rough enough to provide sufficient traction Embedded with LEDs and heating element Weatherproof.

GLASS LAYER

Consists of photovoltaic cells which absorbs solar energy.

Consists of microprocessor board with support circuitry.

A communication device every 12 feet. Heating elements helps to melt snow.

ELECTRONIC LAYER

Distributes power and signals to and from the panels. Waterproof for protecting the electronic layer. It needs to be weatherproof to protect the layers above

it.

BASE PLATE LAYER

Base plate layer

• Each panels covers an area of about 4.39 square feet.

• The Solar panels used are 48 watt • 15840 panels-for 1 mile• 414.984MWh produced per year for

1 mile

SPECIFICATIONS OF THE SOLAR PANEL USED

YES! According to Moh’s scale of hardness, glass used in solar roadways is harder than current asphalt roads.

Are Solar Roadways practically possible?

INTELLIGENT HIGHWAYS power and data delivery. Forms a WAN, with each individual panel containing a microprocessor board with its own address. XBee RF module is added to incorporate wireless communication.

SALIENT FEATURES OF SOLAR ROADWAYS

MICROPROCESSOR BOARD

 POWER GRID:A system of transmission mediums that allow electricity to be transferred at different voltages from the point of generation to our homes.

Problems with current power grid1.Network congestions are occurring2.Need for more information and transparency to customers.3.Can’t support the development of renewable energies.

SMART POWER GRID

Decentralizing the production of electricity Phasor Measurement Units (PMU)  array of sensors would monitor voltage and current. equipped with a GFI (Ground Fault Interrupter)

SMART POWER GRID

The heating system in Solar Roadways maintains a temperature above freezing point using pipes.

 The microprocessor has an uplink to a local weather station to predict precipitation events.

Snow and ice management

Illuminated roads 32x32 array of LED cells.  Configure which LEDs would turn on/off LEDs can also be programmed to warn speed limits.

LED CIRCUIT BOARD

◦ Allow electric cars to recharge at any rest stop made up of Solar Panel

◦ Hard-wired EV charging station that delivers up to a 24 kWh charge in 4-8 hours

◦ Investigating ways to use mutual induction to charge

How do electric vehicles get charged?

Renewability Life span- 20-25 years Road illumination Intelligent highway system Military and rescue assistance Safer travel Reduces dependence on fossil fuels

ADVANTAGES OF SOLAR ROADWAY

Maintenance costs Seasonal efficiency Needs a town planning Still in research and development Needs more testing

DISADVANTAGES

Create an intelligent, secure highway Self-healing power grid Provide safer driving conditions End our dependency on oil and other fossil fuels Traffic management Electric vehicles to recharge anywhere

Future scope:

It's time to upgrade our infrastructure - roads and power grid - to the 21st century.
