Solar Photovoltaic System: An Alternate Source of Energy Introduction
Despite enormous hydropower potential (theoretically 83,000 MW), only about 40 percent of the population of Nepal has access to electricity and this percentage even drops down in the remote areas. Since the rural energy demand is basically for lighting, Government of Nepal (GoN) has its dedicated energy policy to promote Renewable Energy Technologies (RETs) including Solar Home Systems (SHS) which follows the principles of Solar Photovoltaic Systems. Photovoltaic are best known as a method for generating electric power by using solar cells to convert energy from the sun into a flow of electrons.
Solar cells produce direct current electricity from sun light, which can be used to power equipment or to recharge a battery. The first practical application of photovoltaic was to power orbiting satellites and other spacecraft, but today the majority of photovoltaic modules are used for grid connected power generation. Due to the growing demand for renewable energy sources, the manufacture of solar cells and photovoltaic arrays has advanced dramatically in recent years. Solar photovoltaic is growing rapidly from a small base to a total global capacity of 40 GW (40,000 MW) at the end of 2010. More than 100 countries use solar PV. Some 24 GW of solar was projected in November 2011 to be installed in that year, pushing up worldwide capacity to roughly 64 GW. Installations may be ground-mounted or built into the roof or walls of a building.
Electricity and livelihood development is the two sides of a coin. It is certain that in course of time there will be no conventional fuel reservation for production of electricity. Ultimately solar will be the best option for energy during that growing energy crisis

Photosynthesiscell

...Photosynthesis and Solar Cell Technology Introduction to Biology SCI 115 Strayer University The plants ability to utilize photosynthesis plays an integral part in everyday life. The way plants are able to interact with the environment, take “waste” and convert it into oxygen is nothing short of amazing. Through ingenuity and technological advancement, human beings have been able to almost replicate this amazing feet. Solar cells are able to absorb light energy to energize electrons. While the end product may be different, solar cells and photosynthesis both utilize light energy for application. Solar cells and photosynthesis are very similar in how the utilize light energy. The purpose of both the solar cell and photosynthesis is to harness light energy and convert it into usable form. In a solar cell sunlight is absorbed by a semi-conductor. In plants “the pigments within the thylakoid membranes absorb solar (radiant) energy” (Mader, 2009). It is in this instant that both a solar cell and a photosynthetic plant are at its most similar. From here the solar cell converts the solar energy to electricity while, through photosynthesis, the plant produces oxygen as it uses water and carbohydrates to grow and survive. The process of the conversion of light energy and certain characteristics of both photosynthesis and solar cell technology are the similarities that these two share. Once light energy has entered the differences come into play. Solar cells produce the...

Risky Behaviour

...Solar energy, radiant light and heat from the sun, is harnessed using a range of ever-evolving technologies such as solar heating, solar photovoltaics, solar thermal electricity, solar architecture and artificial photosynthesis.[1][2] Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute solar energy. Active solar techniques include the use of photovoltaic panels and solar thermal collectors to harness the energy. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air. In 2011, the International Energy Agency said that "the development of affordable, inexhaustible and clean solar energy technologies will have huge longer-term benefits. It will increase countries’ energy security through reliance on an indigenous, inexhaustible and mostly import-independent resource, enhance sustainability, reduce pollution, lower the costs of mitigating climate change, and keep fossil fuel prices lower than otherwise. These advantages are global. Hence the additional costs of the incentives for early deployment should be considered learning investments; they must be wisely spent and need to be widely shared" The Earth receives 174 petawatts (PW) of incoming solar radiation (insolation) at the upper atmosphere.[3] Approximately 30% is reflected back to space while the...

Photovoltaic White Paper

...Photovoltaic Power Systems Compiled by Tracy Dahl Overview Photovoltaic (PV) technology converts one form of energy (sunlight) into another form of energy (electricity) using no moving parts, consuming no conventional fossil fuels, creating no pollution, and lasting for decades with very little maintenance. The use of a widely available and reasonably reliable fuel source—the sun—with no associated storage or transportation difficulties and no emissions makes this technology eminently practicable for powering remote scientific research platforms. Indeed, numerous examples of successfully deployed systems are already available. The completely scaleable nature of the technology also lends itself well to varying power requirements–from the smallest autonomous research platforms to infrastructure-based systems. This technology can be limited, however, by annual fluctuations in solar insolation, especially at extreme latitudes. Based on semiconductor technology, solar cells operate on the principle that electricity will flow between two semiconductors when they are put into contact with each other and exposed to light (photons). This phenomenon, known as the photovoltaic effect, was first discovered by Edmund Becquerel in 1839. Actual development of PV technology began in the 1950s and gained greater impetus through the NASA space program during the 1960s. Research continues today at national laboratories and within private industry, focusing on increasing conversion efficiencies...

Pv Technologies

...PV Technologies, Inc.: Were They Asleep at the Switch? Case Synopsis: There was unofficial information on the following; - wrt Barstow bids, PVT was trailing behind competitors SOMA Energy and BJ Solar - It was perceived that the above is due to Solenergy’s renewed focus on expense control and the company felt that there was wide difference in the prices quoted by PVT and the other companies. They believed an enhanced maintenance schedule along with a proactive quality control program would compensate for the inferior performance characteristics of the less costly inventers. - If the above information was true PVT would not only lose one of the biggest customer thereby having financial implications but also their leadership status in the market would be at risk ( this could turn out to be critical for PVT especially since there was a huge potential for the solar photovoltaic products which was expected to grow at 30.4% CAGR during the period 2010-2015.) Major Issues Identified - The fact that such critical information got leaked and PVT was caught unaware questioned PVT teams ‘customer management’ skills. - It also reflected the complacency of PVT team especially on two fronts (i)whereby PVT assumed that since Solenergy was their long term customer they may not look at other companies in the market (ii) That by being just ‘quality focus’ they were meeting their customer expectation - PVT was also over-dependant on the fact their best sales person (Jim Salvatori)...

Using Solar Energy to Substitute Kerosene as a Fuel in India

...Rural Solar Electrification as a substitute for Kerosene Subsidies in India - Sushant Vinchurkar Rural Solar electrification as a substitute for Kerosene subsidies in India In a recent article in the Times of India, renowned economist Swaminathan S. Anklesaria Aiyar has posed a million dollar question: “For decades, kerosene has been sold at highly subsidized prices on the grounds that it provides essential rural lighting to villages without electricity. However, if electricity is now available in all villages in some states, and will soon cover the vast majority of the rural population, why should the kerosene subsidy continue, especially when it’s well known that a corrupt, leaky distribution system means that little actually reaches the poor?” The magnitude of subsidy on Kerosene in India: Factual data Kerosene is primarily used in rural households for lighting (see following figure 1). Subsidized kerosene provided through the public distribution system (PDS) is intended to be targeted to those households that are below the poverty line and have ration cards to prove their economic status. Figure1 National Sample Survey Office data for 2004–05 showed that approximately 50 per cent of poor rural households did not have a BPL card and, in some states, such as Bihar and Jharkhand, the figure was as high as 80 per cent (Ministry of Statistics and Programme Implementation, 2007).

Solar Energy

...Abstract Solar Energy: The Eco-Friendly alternative energy source for The world? Solar Energy: The Eco-Friendly alternative energy source for The world? Solar energy is energy provided by the sun, it is in the form of solar radiation, it can be converted into electrical or thermal energy. Around the world a movement has begun, one started by environmentalist, this movement is known as the Go Green Movement. The goal of this movement is to make people aware of the damages that we are causing and effective measures to reverse them. The Go Green Movement focuses on creating alternative energy sources so that non-renewable energy resources such as: coal, petroleum and fossil fuel are not exhausted. Most fossil fuels are obtained through mining processes, which can damage the environment. They damage the environment by releasing acid, mercury and sulfates into the atmosphere. Christina Nunez, in her article for National Geographic states that fossil fuels such as coal should, “be left untouched in order to prevent global temperatures from rising more than 2°C.” (Nunez, 1) This indicates that the burning of fossil fuels such as: coal, oil and gas are factors which contribute to global warming. They contribute to global warming by releasing carbon dioxide into the earth’s atmosphere. In recent years the quandary of having alternate sources of energy has arisen. Solar energy is energy provided by the sun, it is in the form of solar radiation, it can...

...Company Profile Company profile REinVEnTinG A GREAT coMPAnY The year 2008 saw the definitive reinvention of a great company. Less than a decade ago, ACCIONA was one of Spain’s leading construction companies and was actively diversifying and seeking business opportunities worldwide. In the last year, and after divesting Endesa in 2009, ACCIONA has culminated the transformation into a company that is a pioneer in development and sustainability, and a global leader in the development, production and management of renewable energy, water and infrastructure with the minimum environmental impact. This achievement would not have been possible without ACCIONA’s pioneering background. It was created by the first merger in Spain’s construction industry and, in the 1990s, it was the first non-utility to move into renewable energy. ACCIONA is the construction company that has most successfully diversified followed by a process of concentration. Sustainability is a core axis of its strategy, and energy, infrastructure and water are the vectors of future growth. In 2004, José Manuel Entrecanales was appointed Chairman, and he spearheads the Company’s transition towards these three pillars of growth. In 2005, ACCIONA strengthened its position using an innovative strategy based on orienting those businesses towards sustainable development, with a strong international approach. This sweeping transformation was also possible thanks to the enormous investment effort and social commitment...

Electrical Fundamentals

...Introduction Aircrafts require some form of electrical power to operate navigation, taxi, landing, strobe lights and other electronic systems. The electrical system consist of a battery and an alternator (you will find a generator on older type aircraft) to power the system and recharge the battery. You will also find fuses and switches and lights for indication purposes. Some electricity generators are used as backup power or other indication purposes. For example, a volt and/or ammeter are used for monitoring a change in voltage or current. However, this change in voltage or current could be brought about through the means of heat or light, which are electricity generators too. In a situation where primary power has failed, the aircraft storage batteries provide an emergency source of electrical power for operating electrical systems of an aircraft. All of these are connected through several meters (kilometres in large aircraft) of wire and connectors, attached to the airframe with insulation materials. In this report, I will be focusing on how these electricity generators are used in the various sections of the aircraft so as to understand the function they serve. I will be looking at four different methods of electricity generation. They are Magnetism and motion, Chemical Action, Light and Heat. Method of Electricity Generation 1 (Magnetism and Motion) It is important to note that magnetism itself does not create electricity. It requires...

Off Grid Renewable Energy

...of these households are in rural areas and find it geographically challenging to benefit from grid-connected electricity for power supply. In the developing countries, rural areas mainly rely on inconvenient non-commercial resources like wood, agricultural residues etc. as sources of power generation. Hence, Off-Grid power, which can be generated on-site from renewable energy sources such as solar, wind and biomass, plays a major role for the future of rural electrification world-wide. To achieve universal access of electricity, International Energy Agency (IEA) estimates that by 2030 about 171 TWh of Off-Grid electricity will need to be generated for providing power to approximately 210M or 20% of total rural households. This paper focuses on understanding the implementation and impact of three Off-Grid renewable energy systems in three different developing countries. Two of them are successfully implemented and the other is currently under implementation. The fully implemented Off-Grid systems selected for this paper are “Off-Grid Rural Electrification-Ladakh” in India and “Off grid Solar Power System for a rural village” in Malaysia. The system that is currently being implemented is the “Rural Renewable Energy Development Project” in Bhutan. These projects have been selected based on their significant contributions to rural electrification in their respective countries. 1.
