INTRODUCTION
1.1 Background of the Study
hotovoltaic (PV) offers consumers the ability to generate electricity in a clean, quiet and reliable ways. Photovoltaic system is comprised of photovoltaic cells device that convert light energy directly into electricity. It is because the source of light is usually sun; they are often called solar cells. The word photovoltaic comes from “photo” meaning light and “voltaic” which refers to producing electricity.
Therefore the photovoltaic process is producing electricity directly from the sun light. When application require larger amount of electricity and are located away from existing power lines or there is high instability of the power from the national. Photovoltaic system may in many cases offer the least expensive most visible option. It is used today on street light, gate opener and other low power task. Solar cells are gaining popularity in the world as their prices decline and efficiency increases.
PV cells convert sunlight directly into electricity without creating any air or water pollution. They are made of at least two semi-conductor materials. One layer has a positive charge, the other negative.
When light enters the cell, some of the photons from the light are absorbed by the semi-conductor atoms, freeing electrons from the cells negative layer to flow through an external circuit and back into the positive layer, this flow of electrons produces electric current (Alenxandre, 2011).
To increase their utility, dozens of individual PV cells are interconnected together in a sealed, weather proof package called a module. When two modules are wired together in series, their voltage is doubled while the current stays constant. When two modules are wired in parallel, their current is doubled while the voltage stays constant.
To achieve the desire voltage and current, modules are wired in series and parallel into what is called a photovoltaic array. The flexibility of the module system allows designers to create solar system that can meet a wide variety of electrical needs no matter how large or small (Boylestad, 2007).
A grid connected PV system will require a utility interactive DC to AC inverter. This device will convert the DC electricity produced by the PV array into AC typically required for domestic load such as radios, television, lighting, refrigerator, fans, etc. A storage facility i.e. battery is used to store electricity from the PV’s array for use when there is no sun. Any number of module can be connected together to give the desired electrical output and as recommended.
1.2 Statement of Problem
As more electronic devices are used daily, the issue of unstable power is becoming a critical challenge. This issue cannot be overstressed in the nation. Some have suggested the resolution of this issue by using wind energy.
Some of bought the use of dynamos and others implemented the use of dry cells. All of these have been wanting in the area of pollution, complexity and open health hazard. This project proposes to resolve this issue with a PV system that uses a charge controller to regulate the voltage going into the batteries and also to prevent over used of the batteries.
1.3 Aim and Objectives
The major aim of this project is to design and install a hybrid (solar and main supply) system to classes in Computer Engineering Department to provide a backup as an alternative source of power, especially at night for the benefit of students studying at night.
The objectives are therefore as follows:
To reduce power loss to a maximum of 2.5%
To eliminate overheating that could lead to fire outbreak.
1.6 Project Limitation
Every explicit project that comes with advantage definitely has limitations. The limitation of this project is to reduce the voltage drop across the cable 2.5%.
