Solar Power And Solar Energy

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.

Commonly, renewable energy is defined as energy which is able to be captured from existing natural resources that are replenished rapidly, such as flowing water, sunshine, wind, geothermal heat flows and ocean [2]. Renewable energy technologies are required to provide technologies to use one or several renewable energy resources. There are some different types of renewable energy technologies, which include solar energy, bioenergy, hydropower, wind energy, geothermal energy and tidal energy. This thesis project will focus on the solar photovoltaic which is currently one of types of solar energy technologies, and this technology using photovoltaic cells to converts sunlight directly into electricity.Solar photovoltaic system can generate electricity from sunlight through using PV modules, and the system can be integrated into building designs, installed on rooftops, or large scale power plant. With the development of photovoltaic technologies, solar photovoltaic capacity has been increased from 3.7 GW (2004) to 177GW (2014) [3]. Figure 2 shows this change from 2004 to 2014, there is a big trend of increase in these years. The increase of PV capacity can reduce the carbon emission and provides more job opportunities. It also helps to reduce air pollution and make a friendly environment for living. One of the common PV system is

In the last decades energy consumption has come to a time where people started noticing the climate changes and the effect of fossil fuel energy for not only being environmentally destructive, but also causing Global warming (the warming that occurs as a result of increase emissions of greenhouse gases) has become a very big issue worldwide. The fossil fuels (Oil, Coal, and Natural Gas) which is the main sources of the world’s energy sources, is also one of the main causes of the climate change. In addition with some human activities (e.g. through burning fossil fuels), they have contributed immensely to the global warming, which has also affected the climate conditions in the world. The affect of these changes has prompted some people to propose alternative energy like solar panels. According to Abby Gruen, after realizing the issues, the engineers at Bell Laboratories come up with the first useful photovoltaic cell, an alternative to fossil fuel energy but less harmful for the environment and the pocket. Solar panel which uses renewable energy like the sun to light homes heat and produces electricity. Unlike fossil fuel, solar panels is less harmful for the environment. Since it creation few decades ego, just recently solar panel started getting popular in homes in the United States and around the world. When it was invented people were not interested about it, because of the high installation price, however the price has changed dramatically since then. Even though

One of the greenest forms of energy developed by technology is solar energy. Generally speaking, it is the energy taken by the sun and converted into a power source that is usable in everyday life. The United States Department of Energy defines solar energy as: “Electromagnetic energy transmitted from the sun (solar radiation). The amount that reaches the earth is equal to one billionth of total solar energy generated, or the equivalent of about 420 trillion kilowatt-hours” (Department of Energy S). This energy is gained by solar panels that collect energy from the sun. Panels can be used for power in almost any structure, from a handheld calculator to solar-powered homes and cars. Solar energy is very useful, albeit that it does have negative effects. For example, you cannot use solar energy all the time. It is only available when the sun is visible from the sky, and cannot be seen at times such as in bad weather, or at night.

Did you know that the sun is one of the most key sources of renewable energy today? Solar Energy could be the answer to the world’s problems if we use it right. Solar energy is a very clean renewable source of energy, that could stop global warming. Solar energy is created from the sun’s light and heat. It has many positive aspects of usage. One of the most positive aspect of solar energy is how clean it is, it’s one hundred times better than using fossil fuels.

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.

That great ball of fire up in the sky that we call the sun is the ultimate source of much of the power that is generated and used by man. Solar power is full of potential and has many benefits of which some are obvious and a few others that are not so easily realized by us. In fact, the sun has

The search for cost effective and efficient renewable energy is becoming an increasingly important area of study. According to Sampaio, “with the increase of population and technologic and economic development, human beings need more energy to create a better life environment.” Fossil fuel energy sources, while cost effective, have major environmental impacts that add to global warming, acid rain, and climate change. One renewable resource that is sustainable and readily abundant is solar energy, which is a reasonable and readily available replacement for fossil fuel energy sources globally.

Solar energy is a kind of sustainable energy and is the cleanest one for it has fewer side effects than other green energy like hydroelectricity. Solar energy comes from the sunlight, which is generated by the sun infinitely. According to a study (NREL, 2017), the total solar energy that cast from the sun to the earth per hour can meet the energy demand of the whole world in a year. Solar energy is a kind of energy that takes full advantages of light, radiation and heat inside the sunlight. Solar power contains two types: the active one and the passive one. The active solar technologies like photovoltaic solar energy system (PV), and energy conversion between sunlight and heat like solar water heating system which is extensively applied in family and industries. By using external facilities to supply energy, active solar techniques can use electronic equipment and machines to collect and concentrate scattering sunlight. On the other hand, passive solar technologies using architecture designs to utilize sunshine, without any external devices. According to Energy outlook presented in 2007 (REN21, 2008), China will become the biggest energy consumer and the largest greenhouse gases emitter in 2010. Since China began to study solar energy technologies and establishes photovoltaic (PV) around 1985 (Yang et al., 2003), China makes miraculous progress in solar technologies. Although China lacked essential and stimulative policies until 2010 (Zhang & He, 2013),

In the last decades energy consumption have come to a time where people started noticing the climate changes and the effect of fossil fuel energy for been environmentally destructive, by producing pollutions and other effect. After realizing the effect engineers come up with solar panel, an alternative to fossil fuel energy but less harmful for the environment and the pocket. Solar panels which uses renewable energy like the sun to light homes heat and produces electricity. Unlike fossil fuel solar panels are less harmful for the environment. From it creation few decades ego, just recently solar panel started getting popularity in homes in the United States and around the world. When it was invented people were not interested about it, because of the high installation price, however the price have changed dramatically since then. Even though scientific data shows that solar energy is a better alternative to fossil fuel, many people still wondering about global warming, the benefit and the necessity of solar panels

Solar energy has been translated as natural energy source that’s become beneficial for humans. Solar energy is natural energy from the sun that can be used by converting solar cells into useable energy and can be used to run electricity in business, homes, antennas, watches, etc. Solar energy is important in society because unlike fossils, fuel, and oil that will eventually be gone from our earth, solar energy will be the replacement since it is natural source of electricity acquired from the solar rays making it what known to be as clean energy source. Although, there are a lot of reasons such as solar energy being expensive, taking a lot space, and not being a reliable source of energy in the night time, I still believe that solar energy is beneficial for humans in the way that it reduces electricity bills, is a major source of renewable energy, and helps the environment as it does not produces carbon dioxide.

Solar energy is now a great source of renewable energy. Due to the limited stock of fossil fuel, solar panel systems become more popular day by day. Now Industries, houses and defensive forces are using solar panel systems to generate power. The solar panels generate power from sun radiation. Solar cells are also known as Photovoltaic (PV) cells. When sunlight with a specific frequency hits metal, loosely bound electrons emit from the metal as shown in Figure 1. A potential difference is created in between the cathode and the anode. When the anode and the cathode connect, current flows. Solar panel systems use this mechanism to generate power. Then, generated power is carried out to the battery to store and distribute to the load. The main obstacle for solar panel systems is night and cloudy weather, due to low solar radiation.

Photovoltaic cell is of grate impart in the Morden market of electrical generating sector, commonly used by industries and private home etc. as a source of electricity , which have been of existence since , 1950s ‘Inventors at Bell Labs (Daryl Chapin, Calvin Fuller, and Gerald Pearson) developed a more efficient PV cell (6%)

Around the world, there are hundreds of different methods of how to use alternative energy in order to save the earth from burning fossil fuels. Burning these, causes major air pollution and can be detrimental towards the health of thousands of populations. The best type of energy is photovoltaic energy because it possesses many advantages and it outshines the other alternative sources. In one day, the amount of sunlight shining over the United States is over 2,500 times the entire country’s daily energy usage combined.

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.
