Solar panel roads ppt

Introduction
Solar technologies are broadly
characterized as either passive solar
or active solar depending on the way
they capture, convert and distribute
solar energy. Active solar techniques
include the use of photovoltaic
panels and solar thermal collectors to
harness the energy. Passive solar
techniques include orienting a
building to the Sun, selecting
materials with favorable thermal
mass or light dispersing properties,
and designing spaces that naturally
circulate air.
A solar roadway is a road surface that
generates electricity by solar power
photovoltaic cells. One current
proposal is for 12 ft x 12 ft (3.658 m x
3.658 m) panels including solar
Panels and LED signage, that can be
driven on. The concept involves
replacing highways, roads, parking
lots, driveways, and sidewalks with
such a system.
Working principle:
A solar roadway is a series of
structurally engineered solar panels
that are driven upon. The idea is to
replace current petroleum-based
asphalt roads, parking lots, and
driveways with solar road panels that
collect energy to be used by homes
and businesses, and ultimately to be
able to store excess energy in or
alongside the solar roadways. Thus
renewable energy replaces the need
for the current fossil fuels used for
the generation of electricity, whichcuts greenhouse gases and helps in
sustainable development.
Solar road construction:
Existing prototype panels consist
of three layer.
surface layer:
Electronics layer:
Base plate layer:
Advantages of Solar Roadway:
Renewability and life-span
Military and rescue assistance
Roadways already in place
Lighting up of roads
Initial Cost
Disadvantages of Solar Roadway:
Maintenance costs
Seasonal efficiency
Needs a town planning.
Conclusion:
For roughly the same cost of the
current systems (asphalt roads and
fossil fuel burning electricity
generation plants), the Solar
Roadways™ can be implemented. No
more Global Warming. No more
power outages (roaming or
otherwise). 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.

2. CONTENTS Introduction Solar Road Construction Working Principle How it Works? Advantages & disadvantages Features Future Scope Conclusion References

3. INVENTORS OF SOLAR ROADWAYS Julie & Scott Brusaw

4. INTRODUCTION In 2009, the innovative idea of Solar Panel Roads was proposed. In 2010, company named SOLAR ROADWAYS was established. Location : Idaho, US. Funded by US federal government. Aim : to replace current asphalt roads with solar panel roads.

5. 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.

6. Solar Road Construction PHOTOVOLTAIC CELL Photovoltaic cells are used to convert solar energy directly into electricity using semiconductors. This is the active type of solar technology

7. Road consists of 3 layers. Road Surface Layer Electronics Layer Base Layer

8. Road Surface Layer Translucent and high-strength. Designed for reduced skidding chances Weatherproof.

9. Embedded with LEDs and a heating element Tested for traction, load carrying capacity & impact resistance and exceeded all requirements

10. Electronics layer Middle layer. Contains photovoltaic cells. Conversion of solar energy to electrical energy takes place here. Houses the heating element and microprocessors for controlling them. It also houses the microprocessors for controlling lighting LEDs.

11. Base Plate layer Bottom layer. Stores the converted electrical energy. Distributes electrical energy. Made weatherproof.

12. How it Works? Sunlight falls on solar panels which generates electricity This is as same time is transferred to nearby houses and power station LEDs controlled by microprocessors display information on the surface of road Anti icing layer clears the road Also senses changes in weight

13. ADVANTAGES Renewability Life span Initial cost Road illumination Intelligent highway system Military and rescue system Smart always connected roads and vehicles Smart grid Traffic assistance Driver assistance Oil independence

14. DISADVANTAGES High initial cost Road surfaces deposits reduces its efficiency( salt, rubber and dirt) Seasonal efficiency. Needs a town planning.

15. Features of Solar Roadways Accident can be avoided : The roadways can protect wildlife and motorists. The load cells in the solar panels can detect if something is on the surface of the panel. It acts like a weigh machine.

16. (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.

17. (c) 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.

18. (d) Snow/ ICE Management : The roads heat themselves with their embedded heating elements and melt away all the snow .

19. (e) Improved power lines

20. (f) Intelligent Highways Pays for itself Telephone, cable TV, and high-speed internet Intercommunication between road and cars to avoid collision Tracking system embedded.

21. (g) PARKING LOT INTEGRATION

22. Future Scope With the provision of initial investment it can be carried forward. Increased energy requirement in future can only be met with renewable resources of energy, such as that obtained from solar roadways. To reduce the consumption of fossil fuel and to eliminate global warming, the innovative idea of solar panel road is inevitable.

23. COST FOR SOLAR PANEL ROADS $16 per square feet – Asphalt road One panel size 12 ft x 12 ft = 144 sq ft. One panel costs about $6912 $6912 / 144 sq ft = $48 per sq ft - Solar road

24. CONCLUSION Even though the initial cost is high, as it is a system that pays for itself it is a better choice. For under developed and developing countries, it might seem impractical now. But it can be adopted in stages, in future. With technological upgradation in this field, jobs, clean energy and a safer transportation system can be made.
