The charge controller projects the battery
from over-charging, maximizes the charging voltage and current output of
the solar panel.
To achieve the automatic operation of
the streetlight, a photocell or a time, which senses the period of
darkness and lightness, is used to trigger.
The type of
battery employed here is a maintenance free one, which is capable of
supplying few days of back up power in case of bad weather or charger
failure. Also the lamp used in this project work is a D.C operated lamp.
1.1 BACKGROUND OF THE STUDY
This
project is carried out so as to provide an alternative means of
generating electricity through sunlight for lighting purpose.
Also, the effective utilization of natural resources (sunlight) is ensured by the design of this project.
The components required in carrying out this project which are solar
panel, battery charge controller, bulb are efficient enough to yeild the
desired result without the use of power converter.
Therefore, the use of Direct Current (D.C) operated lamp are employed, specifically, LED (Light Emitting Diodes).
1.2 AIMS AND OBJECTIVES
The aims and objectives of this project are:
To power up a street lighting system through solar energy.
To protect the solar battery from quick deterioration as a result of continuous day and night working.
To control a solar powered streetlight automatically.
To utilize the naturally endowed resource (sun).
1.3 SCOPE OF THE STUDY
This
project design is centered on solar energy as fast growing technology
for street lighting with the use of a solar module. The automatic
control process of the light can be achieved by a photocell. Or a timer
which eliminates human intervention for manual switching or control/
1.4 SIGNIFICANCE OF THE STUDY
The
significance of the design and construction of solar operated Automatic
Street light cannot be overemphasized in the sense that it is
financially viable particularly in areas where the cost of providing a
main supply is prohibitive. It has the capability of illuminating large
surface area of land due to high efficiency of the lamp used. Also, it
does not require human intervention to control its operation and
finally, power outages have no impact whatsoever on it.
1.5 METHODOLOGY
In
the process of searching for information on this project, relevant
textbooks, journals and related past project reports in the library were
consulted. Also, several visits to relevant web sites on the Internet
cannot be overloaded.
1.6 LIMITATION OF THE STUDY
Every
project’s have its limitation. The major limitation of this project is
that sunlight used to generate the electricity is not readily available
especially at winter period.
As a result, the streetlight requires
the need for a large battery to use in order to provide at least three
days of stand by operation during cloudy weather without discharging the
battery below its safe operating limit.

ABSRACT - [ Total Page(s): 1 ]In this project work, we are mostly concern about building a simple power streetlight which is automatically operated. There are four main components required to build a solar operated streetlight. The solar array, High efficiency D.C lamp, changes controller and battery of which the solar array is the most expensive. It is the solar array that produced a D.C voltage due to the energy received from the sun during the day , thereby making the battery to charge, as a result, keeping the streetligh ...
