Solar Panels

Introduction

In today's competitive environment, a new technology emerges every now and then. Companies are struggling to win the race of being top in the industry with the innovation and use of latest technologies. These technologies have also impacted our daily lives. The selected technology is the solar panels. A solar panel is a device for recovering the solar radiation to convert it into electrical energy or thermal energy) operable by man.

We all know the sun is important. It provides for plants, animals, and people here on Earth. However, how does the sun do that? It is the sun's energy that makes life on our planet possible. Energy from the sun is called solar energy. It comes in the form of light or heat. Solar energy is what makes you feel hot when you sit in the sunlight. People have used solar energy for thousands of years. Houses were built with windows so that sunlight can get inside and provide heat.

The sun's energy can also be used to heat water and even food. Solar energy can make the magnifying glass burn objects underneath it, causing a fire. This energy from the sun in the form of heat is called solar thermal energy. However, what happens when a shadow or group of clouds blocks the solar panels? The electrons in the silicon will stop moving, which means the electricity can not flow. However, this does not mean that solar energy can only be used on bright, sunny days. Solar panels can have batteries attached to them to store electricity for a rainy day. When the sun is shining, the electricity flows from the solar panel into the batteries. This stored electricity can be used at night or on cloudy days. This technology using solar energy is still fairly new and expensive. However, the sun gives off more energy in one second than people have used since the beginning of time. Imagine what we could do if we used the sun's energy to power our planet (Bomford 2009).

1. Sources of Technology

Energy conservation involves reducing or eliminating the unnecessary waste of energy. It is surprising that 84% of all commercial energy used in the United Kingdom is wasted. About 41% of this energy is wasted automatically because of the degradation of energy quality imposed by the second law of thermodynamics. The other 43% is wasted unnecessarily, mostly by using too many inefficient motor vehicles, power plants, industrial motors, and other devices, and living and working in too many leaky, poorly insulated, badly designed buildings. One way to reduce unnecessary energy waste is to improve the energy efficiency of devices by using less energy to accomplish a task. Therefore, the building can incorporate the use of solar energy. It involves getting more work from each unit of energy that we use. Reducing such energy waste has a number of environmental advantages. To most energy analysts, reducing energy waste is the quickest, cheapest, and cleanest way to provide more energy, reduce pollution ...
