...What is Solar Energy? Sunlight is a renewable energy source which can be converted into usable energy by solar panels. There are two main types of solar energy. Solar photovoltaic (PV) panels directly convert solar energy into a usable form of energy using a PV cell containing a semiconductor material. CSP (concentrating solar power) on the other hand, concentrate energy from sunlight to a heat receiver which transforms energy from heat into mechanical energy, and in turn, solar thermal electricity. Converting Sunlight into Electricity Light striking a silicon semiconductor causes electrons to flow, creating electricity. Solar power generating systems take advantage of this property to convert sunlight directly into electrical energy. Solar panels (also called “solar modulesE produce direct current (DC), which goes through a power inverter to become alternating current (AC) — electricity that we can use in the home or office, like that supplied by a utility power company. There are two types of solar power generating systems: grid-connected systems, which are connected to the commercial power infrastructure; and stand-alone systems, which feed electricity to a facility for immediate use, or to a battery for storage. Grid-connected systems are used for homes, public facilities such as schools and hospitals, and commercial facilities such as offices and shopping centers. Electricity generated during the daytime can be used right away, and in some cases surplus electricity...

...INTRODUCTION Solar energy, energy that comes from the sun, dates back from the 7th Century B.C. This energy is radiant light and heat from the sun which also makes it a renewable energy that is reliable. It started off with people using magnifying glasses to burn ants with the strong sun rays and now we use it for electricity purposes. I have noticed many schools and buildings around my city have had solar power systems installed on the roof tops and in the parking lot. It shows that this is a popular technology that is going to keep growing in the next few years. SUMMARY OF KEY FINDINGS Solar energy can be used in two different ways in agriculture. There is a solar system that converts solar energy to D.C power and there is a solar system that converts solar energy to heat. Solar energy electricity, also called photovoltaics, can be used to power water pumps or it can be stored in a battery for night use. Systems that use the sun’s energy to create heat can be used in the process of drying crops and grains and water heating. As the usage in solar power is expanding, the more workers solar energy companies will be needing. I read an article on the internet that stated “ The solar power industry employs a wide range of occupations in a number of major industry segments: research and development, manufacturing of solar power materials, construction of solar power plants, operations of solar power plants, and solar power installation and maintenance”. If all goes well there...

...‘‘PERSUASIVE SPEECH OUTLINE’’ Solar power is a viable source of energy. ‘INTRODUCTION’ ATTENTION GETTER: It’s the human condition to underappreciate what we are given when we become accustomed to its presence .The everyday convenience of electricity isn’t fully appreciated until a power line goes down and you’re thrust back into the colonial times with candles and fire stoves. Unfortunately as Pakistani’s we visit the dark ages several times a day. So now I ask you to imagine a Pakistan where unlike the false promises of politicians there is actually electricity in every house, where you don’t have to hear the gyrating noise of a generator everywhere you go. A Pakistan which isn’t plunged back into the dark ages every 3 hours. BACK GROUND: With the depletion of the energy resources in the world, governments, industries and scientists are in search of cost effective and readily available energy resources that can be exploited to satisfy the increasing energy demands in the world. Solar energy has been regarded as one of the most paramount and cardinal sources of renewable energy. As per scientists, the energy received from the sun in one hour is more than the whole world’s total produced energy in a year. It would take only around 0.3% of the world's land area to supply all of our electricity needs via solar power. Pakistan is going through a very severe energy crisis right now. Though Pakistan has got a lot on its plate right now, solving this issue would eradicate dozens...

...geothermal energy include that there was about 33 MW of geothermal power online in Oregon producing 165 GWh in 2013, the latest industry survey identified 19 projects under development in Oregon of additional power within the next few years if appropriate contracts are secured, Geothermal power projects have the lowest land density compared to any other renewable power technology, and the U.S. Geological Survey estimates that there are an additional 500 MW of discovered geothermal power resources in Oregon and 1,800 MW of undiscovered resources. Solar energy is another good resource option for Oregon to strongly consider, even though it seems like it wouldn’t be. The Oregon Solar Energy Industries Association (OSEIA) founded in 1981, promotes and advances solar energy utilization. Solar Oregon gives job opportunities and offers volunteer opportunity. Although Oregon is known for being cloudy and rainy, however, Portland General Electric (PGE) says the western Oregon actually receives as much solar energy as the national average, and will produce as much energy as the same system installed in Florida. Values of solar energy include clean energy, lowered accumulative electricity cost, and adds value to your property. The cost of solar panels in Oregon is 95 cents per watt, up to a maximum of $9,500 for energy trusts. Solar energy is obviously a renewable resource, because it comes from the sun. The sun is not going to run out of energy until long after we’re gone. Oregon’s solar energy...

...SOLAR ENERGY INTRODUCTION Without the sun, living life on earth is indeed impossible. Sun as we known is a ball of fire that gives us light and heat. The energy that we receive from the sun is called as the solar energy. With the help of this energy serious problems regarding energy that is needed everyday can be solved. Solar energy means capturing the rays of the sun and storing and its heat. This heat can be converted with the help of solar panels into heat or electrical energy. When we talk about solar energy, there are two kinds of solar energy namely, thermal energy and electrical energy. Thermal energy is something which we can find everywhere and is totally free of cost. It helps us ding our daily chores like dries things such vegetables, clothes, heats water, and many other things. Water can basically be heated in two ways i.e. actively and passively. In active method, when a heating element inside the solar hot water system heats the water during hot season. In the passive method the water is pre heated and flows through a cold inlet that of a conventional electric geezer. Talking about electric energy, the power of the sun is used to produce electricity with the help of solar cells. It can be used through a solar home system that helps in conducting electricity where there is no power supply. Apart from that it can be used a system where the electricity supplying utility is connected to the property and lastly it can be used as a backup system where...

...Solar Energy Technology Solar energy is a kind of renewable energy source, which depends on the sun's rays to generate heat and create electricity. As long as there is a sun shining on the earth, and the sun will never run out of energy; therefore, the solar energy always exist. Solar technology is not new. Its history spans from the 7th Century B.C. Greeks used passive solar which are direct solar gain and indirect solar gain to heat buildings (400 BC). Next, Romans improved it by using glass to absorb heat in the buildings and greenhouses (100 AD). And in 1700, Antoine LaVoisier built a solar heater. Later on, in 1839, French physicist Antoine-Cesar Becquerel observed that shining light on an electrode submerged in a conductive solution would create an electric current. Moreover, in 1860, the First Solar Motor, the heated water was used to drive a steam motor, Auguste Mouchout. Then, in 1883, American Charles Fritts described the first solar cells, which were made from selenium wafers. Almost a century, many scientists had been researching, exploring and keeping update more about solar energy. They had found photoelectric effect, the first use of solar energy at night, provided experimental proof of the photoelectric effect, solar cells developed for satellite, and so on. And nowadays, we have created many things by using the solar energy, such as solar-powered buildings to solar powered vehicles. Solar Energy is divided into five main categories. They are Photovoltaic, Solar...

...based on a review of publicly-filed generation data (available on the EIA website) for various solar power plants. It is premature to draw conclusions about Ivanpah’s performance for the following reasons: • Ivanpah has not yet completed its first year of operations, which includes a partial start-up and optimization performance period. • Ivanpah’s performance obligation is an annual target, not monthly, and is measured on a cumulative basis. • The formula for evaluating performance is complex and considers a number of factors, including time of delivery and weather. As anticipated, Ivanpah has shown steady improvement on an adjusted basis from month to month. We expect to meet all requirements for performance for the first year of plant operation. Why is Ivanpah not producing the amount of power that was expected? Can Ivanpah do anything to increase its production output and run more efficiently? And if so, what can Ivanpah do? What was your involvement, the Commission, in approving Ivanpah’s technology and objective of producing solar energy? What has Ivanpah told you is the issue in their energy production outputs? Who does this impact, are there actual households that will go without electricity? What might Ivanpah have been able to do to provide better options in meeting their energy goals? What is being done now to compensate for the energy? And are...

... Weighting: 25% The concept of renewable energy within Australia, particularly Solar Energy has a huge scope of serious development and benefit to our future energy needs. Our country to this date has the highest average solar radiation per square meter of any country in the world (Geoscience Australia, 2012). Even our solar radiation in the southern regions has a higher overall radiation than countries like Germany, who are one of the most developed nations in terms of Solar Energy. Since late 2012, 10% of Australian energy relies on renewable sources of which 0.03% is Solar (T. Flannery, V.Sahajwalla, 2012). Although this percentage is small, due to the continual evolution of the concept and the current state of the economy and particularly the feed-in tariffs schemes; Solar Energy in Australia is becoming progressively affordable. The current state of Solar Energy in Australia is advancing, though obstacles such as ecological impacts & risks, the heritage & cultural boundaries placed within Australia and the production disadvantages of solar systems itself act as large limitations in the development of the concept. Developments in Solar Energy facilities for large areas such as towns require a large amount of land. This is largely the case for the use of solar photovoltaic systems (AAS, 2010). Although within Australia, around 18% of mainland is considered desert and...

...INTRODUCTION: Solar energy has the greatest potential of all the sources of renewable energy. If only a small amount of this form of energy could be used, it will be one of the most important supplies of energy specially when other sources in the country have depleted energy comes to the earth from the sun. This energy keeps the temperature of the earth above than in colder space, causes current in the atmosphere and in ocean. It causes the water cycle and generates photosynthesis in plants. The solar power where sun hits atmosphere is 1017 W. The solar power on the surface of earth is 1016W. The total worldwide power demand of all needs of civilization is 1013W. Therefore, the sun gives us 1000 times more power than we need. If we can use 5% of this energy, it will be 50 times what the world will require. Electrical Energy that can be produced from the solar energy by photovoltaic solar cells. SPV cell converts the solar energy directly to electrical energy.

...------------------------------------------------- HISTORY OF JAPANESE SOLAR ENERGY A. The Beginning i. The Boom of Solar Power One of the most significant and perceptible booms in the country of Japan recently is one that will probably broaden and remain an enduring fixture, unlike other technological booms that are going on in Japan. Utilizing solar energy from the sun’s rays to heat water has long been frequent in Japan for some time. Nevertheless, in the last decade a collection of photovoltaic cell panels have began to appear mostly everywhere, via the rooftops of homes, businesses, airport terminals, large factories and schools. The most interesting thing about this obvious growth though has been the large number of new homes having solar energy being incorporated into their designs. It’s amazing to see houses being retrofitted with solar panels on their rooftops across Japan. A decade ago, Japan took the lead as the nation producing the majority power from solar energy, a lead which has expanded during the years with production passing 1.13 million kilowatts during the year of 2005. Similar to the case during the 1960s, it’s the exports that are obtaining the headlines, although it’s domestic demand that is actually countersigning the “Solar Boom”. The number one market leader in solar energy in Japan is Sharp Corporation, this industry have reinvested deeply into their production capacity, other manufactures of solar energy are mobilizing into the business as high demand continues...

...ASTOUNDING SOLAR ENERGY FACTS What is solar energy? People often think of solar energy as solar panels mounted on roofs in sunny neighborhoods. This is only part of solar energy (“Solar energy facts,”2012). Solar energy is the oldest energy source. Plants, animal and the microbial life have been using it as a principle energy source since the times of creation. It is in the form of heat and light. In the past years, people have tapped solar energy enabling it to be used at all times; including the nights, in all weather conditions, can be stored as well as be transferred. Solar energy can be defined as the technology used to exploit the sun’s power and make it usable. Solar energy facts * Solar energy makes life a reality. Through photosynthesis, plants absorb sunlight and provide food and oxygen which animals consume to live. Human bodies absorb solar energy this helps to regulate body temperature. Sunlight also provides vitamin D, which is necessary to human health. * Solar energy is an extremely clean energy source. It is environmentally healthier than traditionally fossil related forms of energy since it does not emit any known pollutants to the environment. * The earth absorbs approximately 3.85 million exajoules of energy from the sun. This is big compared to the earth’s use of about 56.7 exajoules. The sun is the sole source of solar energy, believed to last for more than 5 billion years. This means solar energy is the most renewable and viable source...

...CHAPTER ONE Introduction Background: Solar energy has been recognized over the years as a reliable and alternative source of energy. Solar energy is the energy that comes to the earth from the sun. It is commonly known as sunlight. This energy arrives in form of electromagnetic radiation, which is energy that travels in waves. A variety of modern technology is able to capture, convert and distribute solar energy mainly in forms of electricity and heat. The sun is by far the earth’s most available energy resource. If more of it could be harnessed which is just a matter of time, it will provide more than ten times the today’s global demand for energy. It is well recognized because of the energy generation process, which is clean because the source is renewable not a natural resource and it is abundant enough to satisfy the demands of the whole world with future advancements in technology. Solar technologies are broadly characterized into two active and passive. The difference between the active and passive solar techniques is due to their collection, conversion and distribution. The active solar technique which is the main topic is the use of solar energy to replace other sources making it the main supply, while the passive technique is the use of solar energy as a back up or and alternate source of energy incase of any problems with the main supply. The main benefit of solar energy is the fact that it is not only sustainable, it is renewable and this means you can never...
