Design and Installation of 200
Watt Solar Power System
ABSTRACT
The 200W solar system was
determined by load assessment, solar panel number determination, battery
requirement and then inverter sizing. A complete solar panel rated at 200w was
however purchased, together with 2 no. 150A solar battery, 1500W inverter and
also 10A charge controller. These were assembled together with necessary
protective gadgets like cut out switches; to give the 200W expected. The solar
panel was mounted outside the building to allow for maximum collection of sun
energy. It is expected that the system will help the department meet up with
its office duties even when central power is not available.
CHAPTER
ONE
INTRODUCTION
1.1 NEED FOR THE PROJECT
The
general objective of the system is to provide efficiency, steadiness in the use
of power appliances, by ensuring continuous availability of power supply even
in the absence of mains. Uninterruptability of the system made it possible to
eliminate all suspense from mains outage during the execution of an important
and urgent assignment as may be required.
For
better production of the system, the system was operated at a fully charged
condition of the battery. The project was rated 200W of 220V and 50Hz. It was
expected that at this condition, it was favourable to carry load of the
stipulated power. Loads of low power factors are not helpful since they produce
spikes. Overloading is not potent to provide zero change over time and the
inverter had LEDs which indicates mains failure and battery discharge and
system fault.
1.2 SCOPE OF STUDY
This
solar power source makes it possible to provide a clean reliable supply of
alternative electricity free of sags or surges which could be found in the line
voltage frequency.
The
solar power system (SPS) system achieved this by direct current from solar
panel and by rectifying the standard main supply, using the direct current to
charge the batteries and to provide clean alternative power by passing the
energy a filter system.
It
has zero change over time and LEDs which indicates mains fail and battery
discharge level and it provides 100% protection against line noise, spikes
surges and audio frequency interference.

DEFINITION OF TERMS
1.
Inverter unit: This unit converts a DC voltage into AC voltage with the help of
the inverter unit.
2.
Automatic Control Unit: This provides all the required control needed to meet
up the objective of the whole system
3.
Battery Unit: This is a secondary cell unit, capable of storing enough DC
voltage from either sun or AC main, of which is later converted to AC voltage.
