Solar Observation Essay

installing solar panels are changing tastes and preferences of consumer. As Energy Sage (n.d.) stated,

Solar cell or photovoltaic (PV) systems usually transformed energy from the sun in to electric current. It can be measured in terms of ‘‘conversion efficiency’’, the proportion of solar energy transformed to electricity. (Henderson, Conkling, & Roberts, 2007) Sunpower primarily focused on the production of solar cell. But by moving in to wafer manufacturing it soon incorporated in to manufacturing of solar power module units. In general Sunpower manufacturing process needed approximately two times as many steps as the usual solar manufacturing process need and many of these steps were distinctive to Sunpower. Sunpower has nearly 15 -20 established cell manufactures, a handful of silicon – based cell manufacturing upstarts and a number of thin film solar companies offering potentially unsettling technologies.

the mission is scheduled for window between July 31-August 19 2018. The launch will take off at NASA’s Kennedy Space Center, Florida with the Vehicle named Delta IV-Heavy with Upper Stage. During the mission, the max launch characteristic energy by the spacecraft will be 154 km2/s2. At the closest approach, the speed of the spacecraft will be 700,000 kph withstanding a temperature approaching 1377oC at the front of Parker Solar Probe’s solar shield faces. To withstand this temperature, the spacecraft and the instruments will be protected by a 11.5 cm thick carbon-composite shield. Thus, the payload of the spacecraft will be at room temperature.

“Today, the industry’s production of PV modules is growing at approximately 25 percent annually, and major programs in the U.S., Japan and Europe are rapidly accelerating the implementation of PV systems on buildings and interconnection to utility networks.” (Florida Solar Energy Center, 2007)

Solar energy is not only abundant and renewable it is also sustainable and environmentally friendly. As a sustainable energy source, solar energy is able to meet the needs of the present without compromising

Currently, the US solar industry is in a phase of rapid growth. There are a number of firms competeing for market share. This market structure combined with governemtn subsities are allowing the price of solar to drop significantly. As a result the solar industry is very healthy. The solar industry has seen an exponential increase in production capacity. This capacity saw an increase of 41% in 2012 alone to an overall capacity to 4,751 MW. **CITE NEEDED In the overall energy industry, soler has seen an increase in total market share from 10% in 2010 to 29% in 2013, second only to natural gas. There is no doubt that the overall drop in the costs of solar has played a role in this expantion.

In this report I will be investigating into photovoltaic cells, also known as solar cells, and “solar battery” (in early days). I will look at the purpose of them, the technologies in which they are being used, how they work and how they are used based on the actual examples. The other parts of the report will show the example of how they are used in the existing building and what function they have in it. I will also be looking at the advantages and disadvantages of using photovoltaic cell technologies and compare it to alternative technologies available on market that can be used, taking in consideration the aspects of both technologies. At the end of the report I will also look at the sustainable issues as well as the cost issues that come along with using this method in small and large buildings. I will look forward to generally summarize the use of photovoltaic cells and their aspects within the buildings.

The Sun is one of the most significant sources of renewable energy. In one hour the Earth receives enough energy from the Sun to meet its needs for nearly a year. A Photovoltaic (PV)

In today’s world, Earth is facing a major energy crisis and consumes large amounts of energy. Moreover, both developed and developing nations continue to grow reliant on nonrenewable energy to power their rapidly expanding nations. Not only will the world run out of these resources, but the Earth will suffer because of the consequences that come with using fossil fuels. Luckily, there are alternative sources of energy such as the renewable and clean sources of solar energy. For the time being, fossil fuels are more affordable and easy to sell to a variety of markets. On the other hand, solar energy continues to grow and will eventually become more affordable and efficient than nonrenewable energy. Also, solar energy will eventually become cost effective and provide a strong return on investment. Furthermore, solar energy is renewable and will be around even when fossil fuels run out and solar energy will only continue to become more efficient and versatile in the future (“The Pros and Cons”). While fossil fuels may be more affordable, solar energy is cleaner, renewable, and will soon become a far cheaper power source.

For each kw of installed capacity for PV cells the price ranges from $ 1700-2500. This disadvantage does not help the people who need a cheap energy source, because it will be too expensive to buy. Also they are highly inefficient because the good solar panels will only convert up to 45% of the light intake into energy. This means that in order to increase productivity you will need to install large areas of PV panels, which means spending more money. Another aspect that makes them inefficient is that they won't function during the night because they need direct sunlight to convert energy. Even though they cost little money for maintenance the PV panels are still very fragile and can be broken very

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.

A background and description of new solar power generation components are needed to explain how solar energy is more economical, efficient, and cleaner (non-carbon) than most other forms of energy. There are two types of technology for converting solar energy into electricity — photovoltaics (PV) and concentrated solar power (CSP), sometimes called solar thermal that condense or magnify sunlight. The most widely deployed solar electric technology in the world is photovoltaics (PV), another name for solar cells, that basically collect sunlight to create a direct current (DC) electric field. An inverter box converts this DC to

With the dawn of the energy crisis upon us, photovoltaic technology has become a crucial component of discussions centering around sustainability, clean energy, and renewable recourses. This is because there are a number of significant advantages associated with photovoltaic technology. First and foremost, this technology channels our Earth 's largest renewable energy source- the sun. In itself, the sun 's net solar power input to the Earth is more than 10,000 times humanity 's current rate of use of fossil and nuclear fuels. Thus, the energy source harnessed by PV technology is virtually inexhaustible,

Someday, our energy sources are going to run out. What will we do? What can we do? Our major source of energy now is fossil fuel. If that were to run out, there must be an alternate way to get energy. Because of this problem, there has been a lot of research going on. Through that research, alternate ways to get energy have been developed. They include wind energy, solar energy, nuclear energy, tidal energy and many more. In this paper I will focus on the aspects of solar energy. I will look at the history of solar energy, cover the advantages and disadvantages of solar energy and then finally I will talk about the concept of solar energy (how it works) and ways that solar energy can be used in your everyday life.

Reductions in the cost per peak watt can potentially be made to PV technology by increasing the net flux of solar energy to a given cell area. This can lead to reductions in PV prices independently of advances in PV cell technology126. This application of solar concentration saturates carrier traps inside the material, while raising the thermodynamic efficiency limit. The saturation of traps means charge carries are more efficiently transported, leading to improved overall cell efficiency127. Furthermore, under concentrated illumination, the open circuit voltage is found to increase with the incoming flux and thus the overall power efficiency can be increased128,129. Moreover, under solar concentration, light is focussed onto a smaller
