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...

Photoelectric Effect: Solar Energy

...The Photoelectric Effect: How Solar Electricity is Generated Solar energy is an evolving source of power that gradually is becoming more popular to be used as a viable replacement for (or for at least some) of the commonly used power sources around the world today, such as coal, natural gas, and nuclear power. About 67% of electricity generated in the United States comes from fossil fuels, and 39% of that comes from coal plants. Because many scientists of The Industrial Revolution strongly believed that fossil fuels such as coal would eventually run out, some of them looked for different ways to generate energy. Thus, dating far back to the early 1800s, power generation through the photoelectric and photovoltaic effects were discovered. Solar energy is generated by solar panels, which are composed of individual solar cells (or photovoltaic cells) that absorb light from the sun - the light absorbed is then turned into electricity. The absorption of light can be attributed to two processes, one being the photoelectric effect, and the other the photovoltaic effect. While these sound similar, they are closely related, but are different processes. Understanding and using both of them together is extremely important in the process of generation of electricity through solar cells. The photoelectric effect was observed by Heinrich Hertz in 1887 while experimenting on work involved with radio waves....

...------------------------------------------------- Solar panel | | Solar PV modules (top) and two solar hot water panels (bottom) mounted on rooftops | From Wikipedia, the free encyclopedia Solar panel refers to a panel designed to absorb the sun's rays as a source of energy for generating electricity or heating. A photovoltaic (in short PV) module is a packaged, connected assembly of typically 6×10 solar cells. Solar Photovoltaic panels constitute the solar array of a photovoltaic system that generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 365 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, a solar inverter, and sometimes a battery and/or solar tracker and interconnection wiring. The price of solar power, together with batteries for storage, has continued to fall so that in many countries it is cheaper than ordinary fossil fuel electricity from the grid (there is "grid parity")....

...Photovoltaic is a way by which energy from the sun can be directly used for power generation. This method for electricity generation causes no environmental pollution, has no rotating or moving parts, and causes no material depletion. Photovoltaics are also multifunctional. It can generate and operate illuminations, pump water, operate any house hold equipments and appliances, can operate any electrical gadgets and communication equipment. The photovoltaic finds its wide application in village electrification in the developing countries and electricity production for the buildings, commercial areas and industrial sector in cities. BIPV, a segment of the growing Photovoltaic (PV) market, is becoming a popular way to generate electricity by the use of solar energy. Building integrated photovoltaic (BIPV) projects uses nearly 50% of world production of solar PV cells. However, we in India are yet to initiate the promotion of BIPV.

Larrabee, X.-Q. Liu, E. Rehder, K. Edmondson, H. Cotal, R. K. Jones, J. H. Ermer, C. M. Fetzer, D. C. Law and N. H. Karam Spectrolab, Inc., 12500 Gladstone Ave, Sylmar, CA 91342, USA ABSTRACT Multijunction III-V concentrator cells of several different types have demonstrated solar conversion efficiency over 40% since 2006, and represent the only third-generation photovoltaic technology to enter commercial power generation markets so far. The next stage of solar cell efficiency improvement, from 40% to 50%-efficient production cells, is perhaps the most important yet, since it is in this range that concentrator photovoltaic (CPV) systems can become the lowest cost option for solar electricity, competing with conventional power generation without government subsidies. The impact of 40% and 50% cell efficiency on cost-effective geographic regions for CPV systems is calculated in the continental US, Europe, and North Africa....

Solar Energy

...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 modulesE 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....

Essay On Hydropower

...1. Introduction Renewable energy refers to the energy that comes from natural resources, such as sunlight, geothermal heat, wind, rain and as well as tides, which are renewable – able to replenish themselves naturally and continuously over a short period of time. This energy do not diminish and is always restored. Most of the electricity in Brunei is produced by gas-fired power stations in which the resources come from the use of fossil fuels. When fossil fuels are used, they release carbon dioxide, nitrogen dioxide, sulphur dioxide, carbon monoxide and others as well. This is one of the causes for increase in global warming, thus, responsible for climate changes. They are one of the energy sources that are non-renewable as they come from the fossils that will no longer be available once we use them up. The supplies are limited and they are depleting at a...
