New Solar Power Generation System Essay

The creation of solar energy requires little maintenance and solar electricity power plants produce zero emissions. Solar power plants use two different types of technologies: Concentrated solar power and Photovoltaic systems. Concentrated solar power plants, also known as “concentrated solar thermal”, uses solar thermal energy to make steam that is converted into electricity by a turbine. A photovoltaic system, also known as solar panels, generates electricity from sunlight. It is a device that converts light energy into electrical energy.

     Solar energy is the most ancient kind of energy found on earth, for it is as old as the sun. "Solar" means from the sun. The earth is only one of the many planets which is bathed in the sun's overflowing energy. Every second the world receives 95.8 trillion watts of power…just think about that for a minute. Think about how much power the earth just received in the time it took you to read this sentence? It is well beyond the amount of power used in one day. It has the potential to satisfy all our energy needs forever without ever having to use the pollutive fossil fuels ever again. "The problem however, does not lie in the limited source, as do fossil fuels, but in harnessing

Deciding to start a business is brave and adventurous. The first step to success is a brilliant, viable, profitable idea. Whether you have decided to do it on your own because you are tired of working for someone else, or you are laid off after many years in your organization, before you decide to invest your life savings and get buried in debt, consider the big picture, the current economy, your demographic target consumer and do your research. The idea of solar energy is one such brilliant, viable idea. True the demand is present for such energy, but before taking the leap, consider the market saturation, competition, governmental rules and regulations and other determent factor that will influence the success of your

Fig. 9(a) shows the DC-link voltage across the DC-link capacitor of the PV array. The DC-link reference voltage corresponds to maximum power point of the PV array. Fig. 9(b) shows the power demand by the load, and power flows from the grid and PV system generated power. As the PV system generated power could not meet complete power demand of load, remainining power is supplied by the grid. At 1secocond the PV system switched from partially shaded condition to uniform solar insolation. Thus, at this point power supplied by the inverter and grid also varies. Fig. 10(a) shows the grid current which is fully sinusoidal. Fig. 10(b) shows the inverter output current. Fig. 11 shows the performance of system under reactive load condition. In this study, a 500VA reactive load is considered. The figure shows the complete reactive power is supplied by the inverter. Thus the power factor of the system is maintained nearly at

In this modern fast paced world that we live in, there are many issues that are looked over, energy is one of these. As a world, we are dependant on dwindling fossil fuel supplies and take for granted electricity, oil, and gas. There are four completely renewable sources of energy around us that should be used and developed, they are: wind, growing plants, flowing water, and the sun. These sources of energy are the ones we should be tapping, because they are reliable and renewable. Harnessing the suns energy is the most certain and ultimate energy source. Looking at a brief history and some facts about solar energy, a glimpse of the future can be seen, a future not dependant on

The sun is a massive burning ball of hydrogen that outputs gigantic quantities of energy every second. Sunlight is an excellent energy source and the future of using solar power is very exciting. The Sun's energy can be used to heat and cool buildings, generate electricity, operate communication, and GPS systems and even power solar cars. The sun’s energy is clean and solar panels used to harness the energy are low maintenance.

The silicon and conductors in the solar panel converts the light energy into a current of electricity called Direct Current, which flows through to your inverter

In addition, solar energy operational costs are manageable. It is free from monthly charges compared to conventional sources of energy. Solar energy does not require raw materials such as oil and coal, and once the panels are built, there will be no monthly charges. In addition, the prices of fossil fuels are increasing day by day, and this means conventional energy will be very expensive. Solar energy will remain the most capable world’s future power supply because, it is cost effective once the plants are built, and there will be no transport costs like for conventional energy sources. Therefore, solar energy is cost-effective, and will help in future energy supply, as the maintenance cost is affordable, as long as they are installed properly, and are working efficiently ( Hans, 2012). Furthermore, with the improvement and advancement of technology, it will increase its efficiency, and cost of production thus, making it more cost effective and the world’s best

Electrical power is generated by use of photovoltaics by converting sunlight into direct current and this is achieved by making use of materials that are semiconducting and have the properties of photovoltaic effect. Solar panels that have got several number of solar cells are used for photovoltaic systems. Solar photovoltaic energy is considered as a sustainable and cleaner form of power and has an advantage of making use of a renewable source which is the sun. The process of obtaining electricity from the sun has the advantage of having no movement of objects and no environmental emissions, a very clear and known study since for fifty years photovoltaic systems have been in use specialized applications and also for more than twenty years grid connected systems have been put into us (Armentrout and Patricia Armentrout).

In order for one to further understand the importance of solar energy, the problem of global warming must be explained. As defined by Webster’s Dictionary, “Global Warming” is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. With an average increase in atmospheric temperatures, our planet is slowly deteriorating. In order to stall or halt this global destruction, countries must turn to solar energy as a cleaner alternative to the depletion of fossil fuels. Solar energy creates a homeostasis for the climate. Due to its ability to decrease global climate changes, solar power can address global warming in several ways.

Solar energy is the most plentiful and purist renewable energy source available. Because it is completely natural, it is considered to be a clean energy source. It does not disrupt the environment or threaten the Eco-systems the way oil and some other energy sources tend to. Nor does it cause greenhouse gases, air or water pollution. Solar energy is an immensely important aspect of life and has been since the beginning of time. Increasingly, we are learning how to harness this important resource and use it to replace traditional energy sources. Modern technology can utilize this energy in a variety of ways, such as; generating electricity, providing light or a comfortable interior environment, and heating water for domestic, industrial, or commercial use. One day solar energy may well become our primary form of energy. This would lead to a clean environment, less money spent on utilities, and a healthier world. It is highly important because it has the potential to allow technology and nature to co-exist peacefully.

Solar energy and its use isn’t new to the world. It has been used by various societies beginning from 7thCentury B.C, when the sun’s heat was concentrated by glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solar-powered vehicles. By and large solar technology has some environmental, economic, psychological and ethical implications for our society. Actions taken by companies and individuals to increase the use of solar technology will create good local jobs, improve our environment and reduce our dependence on foreign oil while doing what’s ethical and moral for our society.

An inverter is basically a device that converts electrical energy of DC form into that of AC. The Purpose of DC-AC inverter is to take DC power from a battery source and converts it to AC. For example the household inverter receives DC supply from 12V or 24V battery and then inverter converts it to 240V AC with a desirable frequency of 50Hz or 60Hz. These DC-AC

Abstract— This paper presents unipolar pulse width modulation technique with sinusoidal sampling and Space vector pulse width modulation are analyzed for three-phase Diode clamped multi-level inverter from the point of view of the Phase voltages, currents, voltage across the split capacitors and Total harmonic distortion. The necessary calculations for generation of PWM for the two modulation strategies have presented in detail. It is observed that the unipolar modulation ensures excellent, close to optimized pulse distribution results but THD is high compared to SVPWM. Theoretical investigations were confirmed by the digital simulations using MATLAB/SIMULINK software.

Abstract: The current energy situation with fossil fuels as the main source of the world’s energy has two main flaws: fossil fuels contribute to global warming via the greenhouse effect and they are limited in the quantity that remains. Solar power solves both of these problems and can be captured by utilizing photovoltaic cells. However, photovoltaic cells have their own drawbacks due to their high costs of installation and maintenance.
