1.0 INTRODUCTION
The sun provides the energy to sustain life in our solar system. In one year, the earth receives enough energy from the sun to meet its energy needs for nearly a year. Photovoltaic is the direct conversion of sunlight to electricity, it is a beautiful alternative source of energy to conventional sources of electricity for many reasons it is safe, silent, non – polluting, renewable, highly modular in that their capacity can be increased incrementally to match with gradual load growth, it is reliable with minimal failure rates and projected service lifetimes of about 20 to 30 years.
It requires no special training to operate, it contains no moving parts, it is extremely reliable and it’s virtually maintenance free, and can be installed almost anywhere.
A photovoltaic system is a complete set of interconnected components for converting sunlight into electricity by photovoltaic process including array, balance of system and load. The intensity of sunlight that reaches the earth varies with time of the day, season, location and the weather condition, the total energy on a daily or annual basis is called Irradiation and indicates the straight of sunshine. Irradiation is expressed in Whm – 2 per day or KWh.m-2 per day.
Different geographical regions experience different weather patterns, so the site we live is a major factor that affects the photovoltaic system design, the orientation of the panels, finding the number of days of autonomy where the sun does not shine in the sky and choosing the best tilt angle of the solar panels.
1.2 AIM
The aim of this project is to install a 2KVA stand – alone photovoltaic system, using an office in physics department as a case study.
1.3 Objectives
1. To generate electricity from solar energy in which the source is free in nature and abundant.
2. To find solution to irregularity in power supply by PHCN
3. To carry out the system sizing in solar power generator.
4. To study the performance of each component constituting the solar power generator.
1.4 Significant Study
In respect to failure of power supply and perpetual increase in fuel price to run power and most times fuel scarcity, there is need to introduce the use of solar energy power system towards a stable power supply for developing and developed nations of the world.
1.5 Definition of Terms
SUN – Source of energy
SOLAR PANEL – It’s device that converts light energy to electrical energy
SOLAR REGULATOR – It’s a device that regulates from 40VDC to 28VDC
BATTERY – It’s a device that serves as reservoirs/storage device
INVERTER – It’s a device that converts D.C (12v) [Battery/Solar] 28VDC to AC 220AC.
