()
Science Lab. Technology

ABSTRACT

The research work focused on the heat absorption ability of some materials, silver aluminum and copper wires. The result showed that silver has the highest solar absorption rate (0.0710C/min) followed by copper (0.0570C/min) and lastly aluminum (0.0430C/min). It is therefore recommended based on this work that silver material should be used in the construction of different solar devices such as solar panel because of it high solar energy absorption ability compared to others.

CHAPTER ONE

1.0     Introduction

1.1     Background of the Study

The sun is a tremendous source of energy. Each year, the amount of solar energy received by the earth corresponds to about 7,000 times than that consumed by mankind.

It arrives in luminous form (light), conveyed by photons generated by nuclear fusion of hydrogen with the sun (summers et al., 2003).

Sunlight has the potential to supply our energy needs, provided that it is converted efficiently and economically. Hence the development to two main avenues for the exploitation of solar energy, namely photovoltaic (solar panel) and thermal technology. While the later relies directly on the heat created by the sun’s radiation, the former, possibly the most familiar to the general public converts’ solar radiation into electricity. Solar panels harness the sun’s energy in the form of light and convert the energy into electricity. Although the average consumer might associate solar panels with residential rooftop assemblies, solar panels, are available for a wide range of applications, including powering individual gadgets, electronic devices and vehicle batteries (Thomas, 2016).

The smallest unit of a solar panel is the solar cell, also called a photovoltaic, or panel (Lissa 1999) a collection  of two or more panels is called an array.

According to the U.S. Department of energy, panels can gather between 10 watt and 30 watt (Ulanoff and Elon; 2015). This broad, range of panel output represents the variety of solar panel products on the market. While small panel systems gather enough electricity to power consumer devices, large system gather enough wattage to power residence.

1.2     Aim and Objectives  

The main aim of this research work is to determine the solar energy retention ability in some materials; aluminum, silver and copper.

Comparing the solar energy absorption rate of these materials and thereby making useful recommendations.

1.3     Scope and Limitation

The research work was only limited to solar energy retention ability in some materials which include silver, Aluminum, copper.

1.4     Definition of Terms

          Solar Energy

Solar energy is a radiant energy and heat from the sun that is harnessed using a range of ever-evolving technologies such as, solar heating, photovoltaic, solar thermal energy and artificial photosynthesis (Bell and Fairchild 2011; Bonadonna 2000).

          Heat Energy

Heat energy is defined in physical as the transfer or flow between two objects due to thermal energy across a well defined boundary around a thermodynamic system. The thermodynamic free energy is the amount of work that a thermodynamic system can perform (Adkins, 2005).

Heat energy can be transferred from one object to another and the transfer or flow due to temperature difference between the two objectives.

          Conduction

Conduction is the transfer of heat by microscopic collisions of particles and movement of electron within a body (John and James 2002). Conduction takes place in all phases of matter, such as solid, liquid, gas and plasmas. The particles vibrate in their mean position as the energy is transferred from molecule to molecule.

         Convection

Convection is the movement of group of molecules within fluids such as liquid or gasses and with rheids. Convection takes place through advection, diffusion or both (Incropera et al., 1999). Convection involves the movement of the molecules of the heated fluid.

           Radiation

Is defined as the process by which heat energy is transferred from one point to another without heating the intervening medium. Radiation gives out a form of energy which is called radiant energy, radiation heat can be detected by an instrument called thermopile (Dunn and Peter 2014).
