3. INTRODUCTION  A Solar Panel is a packaged interconnected assembly of solar cells  A Solar roadway is a road surface that generates electricity by solar power photovoltaics.

4. WORKING PRINCIPLE  Daylight produces electricity using a solar cell. This charges a battery. At night the battery powers the flashing unit.

5. CONSTRUCTION OF PANEL Existing prototype panels consist of three layers  Road surface layer  Electronics layer  Base plate layer

6. ADVANTAGES  Renewability and life-span  Military and rescue assistance  Roadways already in place  On-the-go charging

7. DISADVANTAGES  Costly  In-road electric vehicle charger  Solar-charged vehicle  Photovoltaic system  Solar cell

8. CONCLUSION  The Renewable energy replaces the need for the current fossil fuels used for the generation of electricity, which cuts greenhouse gases and helps in sustainable development.

9. ANY QUERIES..? ANY SUGGESTIONS?
