Solar Power The Green Energy Source

In this energy driven world, a source of energy which is pollution free, silent, limitless and renewable is very important. Solar energy and solar power electricity is the form of energy which is which fulfills this criteria. Energy generated by solar panel and solar cells yields the most valuable source in present days. Using sun’s energy was quite common in ancient time, but in modern civilization emitting solar energy and generating solar power electricity to utilize it in many aspects has become very useful concept and process. rnSun, located at the centre of the solar system is the main source of potential energy. Using that energy directly into action is the main objet of solar power generation. Solar electricity is generally created by using Photovoltaic technology. It converts solar energy into solar electricity. Photovoltaic systems utilize sunlight to power electrical equipment. A PV cell mainly consists of two or more thin layers of semi-conducting material. The materials are mostly silicon. The plates are exposed to the lights and electrical charges are generated. This charge is directly converted into DC. The PV equipment generates solar electricity without emitting s any greenhouse gases, and the operation is virtually silent. During the day, the electricity generated by the Solar PV system can either be used immediately or can be stored and then used in commercial purpose such as selling it to one of the electricity supply companies. On the other hand, in the evening, when the system is unable to provide the electricity, the power supply can be bought back from the network. Here the main grid itself is acting as a electric energy storage system, and hence the PV system does not require a battery storage. This kind of Grid connect PV systems are generally integrated into buildings providing pollution and noise-free solar power. It can be incorporated into buildings in different ways. rnLeisure industry is a substantial market for PV technology. Here the systems use batteries for storage of solar power. When larger amounts of solar electricity are required, they can be combined with a biomass generator or a wind turbine to yield energy in a hybrid power supply system. However, there types of PV Cell available in the market. Monocrystalline Silicon Cells are the most common among them. The main advantage of this kind of cell is high efficiencies that is normally 15%. Multicrystalline Silicon Cells are also widely used. These are cheaper to produce but average efficiency level is 12%. Amorphous Silicon cells are also very useful as they absorb light more effectively than crystalline silicon. However these cells less efficient than crystalline based cells. Although, the low cost makes them suited for many applications, where high efficiency is not required. The solar electricity system has changed the face of contemporary world in many ways. Using solar energy to power modern day equipments and generating solar electricity through solar panels is an evolutionary process. It is safe, unlimited, energy saving, and cost effective. However, the most important aspect of solar electricity is that it is renewable and eco-friendly. In today’s world where limited resource and pollution are the main concerns, solar energy and solar electricity solve these problems very effectively.
