Development & Utilization of Solar Energy

1. What is Solar Energy?

Solar energy is the energy received by the earth from the sun. This energy is in the form of solar radiation, which makes the production of solar electricity possible. It uses energy from the sun to react with chemical materials to produce positive and negative charges. When this reaction happens multiple times, energy is created.

2. Advantages of Solar Energy

Solar energy is vital to support life on earth, it helps to grow our food, light our days, influence weather patterns, provide heat, and can be used to generate solar electricity. Because traditional energy production methods create environmental and health concerns, it is beneficial for lawmakers and scientists to investigate methods of energy production that are cleaner and more cost-effective. Solar energy has been found to be a very clean type of energy that can reduce pollution and also reduce the costs of energy in homes and businesses.

3. Applications of Solar Energy

· City Residential homes
Recent years have seen rapid growth in the number of installations of PV on to buildings that are connected to the electricity grid. The central driving force though comes from the desire of individuals or companies to obtain their electricity from a clean, non-polluting, renewable source for which they are
prepared to pay a small premium.

· Industrial Applications
For many years, Solar Energy has been the power supply of choice for Industrial applications, where power is required at remote locations. The examples are powering repeater stations for microwave, TV and radio, telemetry and radio telephones.

· Holiday Properties
Photovoltaic Systems are frequently the preferred solution for holiday homes, which have no access to the electricity grid.

· Water Pumping, lighting, heating in the Developing World
Apart from off-grid homes, other remote buildings such as schools, community halls, and clinics can all benefit from electrification with Solar Energy. Solar energy can also power area lighting to enable more outdoor activities after dark or improve security, and to illuminate signs or advertising boards.

· Central Power StationsWorld
Central Power applications use solar energy in the same configuration that a Utility would utilize a major power station. This is distinctly different from the other applications on this page, which are known as "distributed power" or power distributed in small aggregate amounts of power, usually close to the point of use of the electricity.

· Commercial buildings
On an office building, atria can be covered with glass/glass PV modules, which can be semi-transparent to provide shaded light. On a factory, large roof areas have been the best location for solar modules.

· Other Recreational Applications
Solar Power is frequently used in consumer product applications which require small amounts of energy (like calculators). Another frequent use is for Recreation Vehicles (RVs) and Boating to recharge the battery for recreational use activities.

4. The future of Solar Energy

In the 21st century, solar power has already become a small part of daily life. From solar heated swimming pools to solar powered homes, some examples already exist to show the useful application of the clean, safe, sustainable power of the sun. Yet many wonder if small applications will be all solar power is capable of handling. Certainly, the difficulties of large solar plants are many, although many experts continue to insist that the future of solar energy is quite sunny.
Out of all the renewable sources of energy that could be tapped to create electricity, solar radiation is now, by far, the most favored. Although some may argue that geothermal energy is truly endless, the fact is that billions of dollars are currently being poured into research related to creating more efficient and better solar cells or solar thermal installations. The technology that allows for harvesting photons and turning them into electricity has evolved considerably over the last decade, but using it on a large scale is still prohibitively expensive, Technology Review informs.
