6. SOLAR PANEL
 4.5 TO 5V
 It convert light from the
sun into electric current
through the photovoltaic
effect.

7. DYNAMO
 A dynamo is an electrical generator that produces direct current with the
use of a commutator
 2.5 to 3v
 It generates the required energy through speed breaker

16. APPLICATIONS AND FUTURE ENHANCEMENT
APPLICATIONS
1.This system is designed for outdoor applications in un-electrified rural areas.
2.This system is an ideal application for campus and village street lighting.
3.Solar street light system is an ideal lighting system for roads, yards, residential
colonies, township, corporate offices, hospitals educational institutions and rural
electrification.
FUTURE ENHANCEMENT
There is always chance to improve any system as research & development is an
endless process. Our system is no exception to this phenomenon. The following
developments can be done in future for Speed Break Based Street Light Control: In
future this module can be implement to activate the Street Lights based on the
number of persons arrived.

17. ADVANTAGES
 In general mode, the power savings is about 50% .
 In dim mode, it is about 35%.
 Using LED’s in this technology, it provides cool
environment unlike HID lamps.
 Utilization of energy is optimized using this technology.
 Street light gives a bright light over a semi circle of radius
30 feet.

18. DISADVANTAGES
 Operative and maintenance is cost effective.
 Initial and maintenance cost is high.

19. CONCLUSION
This concept falls under the subject of non-
conventional energy resources, out of the many
alternative energy resources one dependable source is
solar energy, but it is quite costliest affair. Therefore,
alternative cheapest source is to generate electricity
from speed breaker. This technology proven here is the
ultimate inexpensive source of all known forms of
energy
