  Introduction: • The solarroadway is a series of structurally engineered Solar panels that are driven upon. • The idea is to replace all current petroleum based asphalt roads, parking lots, and driveways with Solar Road Panels that collect energy to be used by our homes and businesses. • The ultimate goal is to store excess energy in or along-side the Solar Roadways.
• 4.
  Photovoltaic cell : •Photovoltaic cells are used to convert solar energy directly into electricity using semiconductors. This is the active type of solar technology.
• 5.
  Solar Roadways :What does it mean ? • 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.
  Solar Road Construction I.Road Surface Layer II. Electronics Layer III. Base Layer
• 7.
  I. Road SurfaceLayer : • Translucent and high-strength, it is rough enough to provide sufficient traction, yet still passes sunlight through to the solar collector cells embedded within, along with LEDs and a heating element. •
• 8.
  II. Eectronics Layer: • It contains photovoltaic cells which absorbs solar energy. It also contains a microprocessor board with support circuitry for sensing loads on the surface and controlling a heating element with a view to reducing or eliminating snow.
• 9.
  III. Base Platelayer : • While the electronics layer collects energy from the sun, it is the base plate layer that distributes that power 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.

  ROAD SURVEY OFINDIA • India has a road network of over 46,89,842 kilometers as on 2013. • In which National highways comprise 1.7% of India's total road connectivity. • These highways can produce 450TWh of electricity according to references when they are surfaced by solar panels. • But India needs upto 991TWh of electricity. • This implies that if 0.1% of total road network of India is surfaced with Solar Roadway panels, it would illuminate our nation.
• 11.
  Features of SolarRoadways : (a) Accident can be avoided : • The roadways can protect wildlife and motorists. • The load cells in the soalr panels can detect if something is on the surface of the panel. It acts like a weigh machine.
• 12.
  (b) Illuminated roads: • The Solar Roadways will have LEDs which will illuminate the lanes. The LEDs can be programmed to show the instructions such as - SLOW, STOP, GO, SPEED LIMIT, etc.
• 13.
  (c) Traffic ManagementSolution • Each solar panel contains a microprocessor that monitors and controls the panel, while communicating with neighbouring panels and the vehicle travelling.
• 14.
  (d) Electric Vehicles: • Electric vehicles are on the way. More and more car manufacturers are offering electrical options • EVs can be rechargeable at any convenient located rest stop or at any parking lots. • Owners can plug their car in and recharge while not driving.
• 15.
  (e) Snow/ ICEManagement : • The roads heat themselves with their embedded heating elements and melt away all the snow
• 16.
  (f) Improved powerlines

  ADVANTAGES • The solarroadways distributes its electrical power to all business and homes connected to the system via their parking lots and driveways. • It generates electrical power from the sun and becomes our nations decentralized, intelligent, self-healing power grid, replacing our current deteriorating power distribution infrastructure. • The Solar Road Panels heat themselves for snow and ice removal in northern climates. No more need for snow removal. • The Solar Roadway produces clean, renewable energy. No pollution, no greenhouse gases, no by-products, and the Solar Road Panels are completely recyclable or reusable • The life span of the solar panels is around 30-40 years, much greater than normal asphalt roads, which only last 7-12 years.
• 19.
  DISADVANTAGES • The startup and maintenance costs of building will be extremely high. Have to invest almost 3 times more than the conventional roads. • The average efficiency is currently 20% • It cannot be constructed in the poorest developing nations due to the high initial start-up costs. • Seasonal Efficiency.

  CONCLUSION : 1. Eliminatethe need for nuclear power plants. 2. End our dependency on oil and other fossil fuels (oil, coal and natural gas). 3. Cut our nation’s greenhouse gas emissions by over 50%. 4. Provide safer driving conditions. 5. Snow & ice management 6. Traffic management 7. Wild life protection 8. Usage of recycled material
