This article will tell you how to make a solar cell at home, and after making this you can light up your little things like a clock, radio, etc. Now your solar cell is ready to be attached to anything to the wire which is attached to copper sheets.
Place solar cell to the sunlight for use when water were heat up solar cell started doing work. This article provides information on the process of generating solar power and details various occupations in the solar industry. Because of a growing interest in renewable energy and the increasingly competitive prices of alternative energy sources, solar power has received a lot of attention over the past several years. The relatively steep cost of solar power compared with traditional sources of electricity generation is caused by the high cost of manufacturing and installing solar panels. Solar power is used to generate large amounts of power on a utility scale and to supply individual residences and businesses with electricity. Utility-scale solar power plants supply large amounts of electricity to the power grid along with traditional sources of power, such as coal and natural gas plants. Commercial solar power is used by business establishments, such as office buildings, warehouses, and retail stores, which are able to install large groups of solar panels known as photovoltaic (PV) arrays, on unused land, rooftops, or parking structures. Residential solar power is generated by homeowners who have solar panels installed on their roofs in order to provide power to their homes.
Although some areas of the United States are better suited for solar power than others, solar energy can be harnessed in any geographic area because of the sun's vast reach. Photovoltaic panels have traditionally been used for smaller scale electricity generation, particularly for residential or commercial use in individual buildings or complexes, while CSP is used for utility-scale electricity generation in solar power plants. Modern photovoltaic solar cells were developed in the 1940s and 1950s, and the technology has evolved rapidly over the past several decades.
Photovoltaic power uses solar cells that convert the energy of sunlight directly into electricity through the photovoltaic effect. Usually, several panels are arranged into an array, which can be scaled to produce enough capacity to generate the desired amount of power. The first large-scale solar power plants in the United States were concentrating solar power (CSP) plants.
Solar power towers, another type of CSP technology, were first used at experimental power plants in the California desert during the 1980s and 1990s; improved solar power towers are currently being developed for newer CSP plants. Solar power can be used for another important purpose: the heating of water for residential, commercial, or industrial purposes. Solar water heating systems are best suited to warm climates, but they can be effective in colder climates as well. Usually, solar installers mount the thermal collectors for solar water heating using similar equipment as used to install photovoltaic panels, but thermal collectors are used instead of panels. 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, operation of solar power plants, and solar power installation and maintenance.
Following are descriptions of the most common jobs in the solar power industry; for each occupation, job duties are listed, along with the credentials needed for the occupation, including education, training, certification, or licensure. The majority of the occupations listed here are not specific to the solar power industry—they exist in many other industries as well. Solar power is still gaining popularity and acceptance, so research and development are key aspects of the industry. A doctoral degree is a necessity for scientists that conduct original research and develop new products; however, some workers may enter the scientific fields with a bachelor's or master's degree. Engineers apply the principles of science and mathematics to develop economical solutions to technical problems. Engineers are one of the most sought-after occupations by employers in the solar power industry. Engineering technicians assist engineers with solving technical problems in research, development, manufacturing, construction, inspection, and maintenance. Manufacturing in the solar industry focuses on three technologies: concentrating solar power (CSP), photovoltaic solar power, and solar water heating.
The electrical circuitry of solar cells is very small, and microscopic contamination can render the cell useless. Computer-controlled machine tool operators are workers who run computer numerically controlled (CNC) machines, a machine tool that forms and shapes solar mirror or panel components. Welding, soldering, and brazing workers apply heat to metal pieces during the manufacturing process, melting and fusing them to form a permanent bond. Coating and painting machine setters, operators, and tenders apply coatings to solar panels, which can be a complicated process that must be done with a high level of precision. Before painting or coating a mirror or panel, workers prepare the surface by sanding or grinding away any imperfections. Coating and painting workers may be exposed to dangerous fumes from paint and coating solutions and other hazardous chemicals.
Electrical and electronics installers and repairers work on a number of the complex electronic equipment that the solar industry depends on for a variety of functions. The level and type of training necessary for occupations in the solar power manufacturing process varies.
Building a solar power plant is complex and site selection requires years of research and planning. Real estate brokers in the solar industry must have specialized knowledge of property specifications for solar power plants and the regulations in place for obtaining the property.
Construction managers oversee the construction of solar power plants, from site selection to the final construction of the plant. Welders who work in solar power plant construction are important for both CSP and photovoltaic plants.
Some CSP plants have a secondary source of power generation, such as natural-gas powered turbines, that will generate power at night or when the weather doesn't allow for sufficient solar power generation.
Solar photovoltaic installers are key to the process of solar panel installation and maintenance.
Solar photovoltaic installers are often self-employed as general contractors or employed by solar panel manufacturers or installation companies. The first section details a brief history of solar power in the United States, followed by an overview of how solar power is generated, which entities use it, and the technology involved in supplying solar power. Bureau of Labor Statistics (BLS), Occupational Employment Statistics program and the Solar Foundation, this article represents the second publication in the Bureau's green careers series. However, solar power generation itself is not new; it has been used for more than half a century, mostly on a small scale or for specialized purposes, such as generating electricity for spacecraft and satellites or for use in remote areas. However, the cost of solar power has been trending downward as technology has improved and manufacturers have learned how to improve production efficiency. It can be used for such purposes as heating water, heating and air conditioning homes and commercial buildings, and powering streetlights. Solar power plants typically generate several megawatts of power, comparable to small or medium coal- or gas-fired plants.
The first method uses photovoltaic (PV) solar panels to generate electricity directly from sunlight. However, photovoltaic solar plants recently started generating electricity in California, Illinois, New Jersey, Nevada, and Florida.


A single cell can produce enough electricity to power a small device, such as an emergency telephone, but larger arrays are required to power a house or building. Built in the California desert in the 1980s and 1990s, these plants are still among the largest, most powerful solar generating plants in the world. Residential solar water heaters generally consist of roof-mounted solar water collectors that directly heat water using sunlight or indirectly heat water by using solar collectors to increase the temperature of a heat-transfer material and pump it to a heat exchanger, which creates the hot water. A plumber is needed to connect water pipes to the plumbing system of the house, pool, or commercial building. Although BLS does not have wage data specifically for occupations in the solar industry, BLS is currently in the process of collecting data to measure green jobs. Although many of these occupations require special skills unique to solar power, skills can be acquired in other industries in most cases.
Most scientists in the solar industry work in an office or laboratory and also spend some time in manufacturing facilities with engineers and processing specialists. In the solar power industry, physicists work with chemists, materials scientists, and engineers to improve the efficiency of solar panels.
Using this knowledge, chemists in the solar power industry are able to improve on solar cell design, develop new materials for making solar cells, or improve existing materials. Current research in the solar power field is focused on developing new materials, especially thin-film cells, and decreasing the cost of photovoltaic panels. Engineers are typically employed by manufacturers of solar equipment and may travel frequently to different worksites, including to plants in Asia and Europe. According to the Solar Foundation, 53 percent of manufacturing firms reported difficulty in hiring qualified engineers in 2010. In the solar industry, they work with semiconductors, metals, plastics, glass, and composites (mixtures of these materials) to create new materials that meet electrical and chemical requirements of solar cells. In the solar power industry, they design equipment and processes for large-scale manufacturing, plan and test methods of manufacturing solar cells, and supervise the production of solar cells. They are responsible for designing the electrical circuitry of solar panels and supporting devices for panels, such as inverters and wiring systems. In the solar power industry, they are concerned primarily with increasing productivity through the management of people, the use of technology, and the improvement of production methods of solar cells or mirrors. Engineers in the solar power industry work on the machines used in the manufacturing of solar panels. In the solar power industry, computer software is used in forecasting weather and sunlight patterns to assess the feasibility and cost of generating solar power in a particular area. However, because of the complexity of some systems, a significant number of jobs require a master's or doctoral degree. However, BLS does have wage data for the Semiconductor and Other Electronic Component Manufacturing industry group, which includes production of solar panels.
However, the vast majority of solar manufacturing firms focus mainly on photovoltaic solar power and producing photovoltaic panels.
Photovoltaic panels are placed in an aluminum frame and are typically encased in glass or laminates to protect them from the elements.
Workers are usually required to wear masks and special suits to protect them from the fumes produced by paint, solvents, and other chemicals. They are responsible for assembling the complex electrical circuitry in a photovoltaic panel, as well as assembling the components, such as inverters or controls, that connect to solar panels.
They determine which machines will be used, whether new machines need to be purchased, when overtime shifts are necessary, and how to improve the production process. However, BLS does track wage data for the Semiconductor and Other Electronic Component Manufacturing industry group, which includes production of solar panels. The proposed site must meet several criteria: large, relatively flat site, adequate sunlight, and minimal environmental impact once built. In the solar power industry, they study particular areas being considered for development of a solar power plant. They can help determine if solar power will be a cost-effective way to generate energy in a particular area by studying past weather patterns and using computers to create models of expected weather activity.
Many solar power plants are built in desert areas that have fragile ecosystems and numerous protected species. Many plants require flat, unobstructed ground in order to line up the solar panels or mirrors, and equipment operators operate machinery to clear and grade the land. At photovoltaic plants, welders are instrumental in building the solar panel mounting systems. However, BLS does track the wage of occupations in the Utility System Construction industry group, which includes construction of solar power plants.
The wages shown are median annual wages for the United States as a whole; however, wages do vary by employer and location. They monitor the solar arrays and generators and regulate output from the generators, and they monitor instruments to maintain voltage to regulate electricity flows from the plant. Power plant operators are responsible for monitoring this equipment and deciding when to switch from solar generation to the secondary source.
However, BLS does have wage data for occupations in the Electric Power Generation, Transmission and Distribution industry group, which includes the distribution of electricity generated by solar power plants.
Installation companies typically specialize in installing certain types of panels and provide some maintenance and repair services.
If the panels are damaged during the installation process, the company has to cover the cost of repair or replacement. She enjoys starting articles about real problems she has in life, as well as ones about quirky topics like How to Use Life Hacks. As solar power becomes more cost-effective, it has the potential to make up a larger share of growing U.S. Large scale solar generation was mostly developed in the 1970s and 1980s, and is considered a clean energy because of its lack of emissions. In addition, as solar power generation becomes more widespread, the cost of installing solar-generation capacity will continue to fall.
Manufacturing workers make the equipment used in solar power generation, such as mirrors and panels. Other large solar panel manufacturing facilities are planned to begin construction over the next few years in many states. The second method is known as concentrating solar power (CSP) and converts sunlight into heat to produce steam, which is then fed through conventional steam-turbine generators to generate electricity. Solar energy is still used to power the International Space Station and the vast majority of satellites. A new technology allows solar panels to be placed on a thin strip of backing, usually aluminum, and covered with a plastic film, which decreases the weight and cost of a solar panel. Utility-scale photovoltaic plants consisting of thousands of solar panels are a more recent occurrence. Solar water heating systems may be used to provide hot water to a home, a swimming pool, or for commercial purposes. For many positions, experience in other industries is desired by employers in the solar power industry.
For example, new materials have been developed that allow for low-cost and lightweight thin-film solar panels that are less expensive to produce and easier to transport than glass- or laminate-coated solar panels.


Physicists also find new materials to use for solar panel generation, such as the thin-film photovoltaic solar panels.
They typically focus on semiconducting materials, which are usually silicon-based materials or organic compounds, because most solar panels are made of semiconducting materials and some newer thin-film panels are made out of organic materials.
Chemical engineers in the solar industry typically focus on semiconductors or organic chemistry, since most solar panels are made of semiconducting materials and some newer thin-film panels are made out of organic materials. In power plants, software is used to monitor the equipment and to adjust the direction of mirrors or photovoltaic panels so that the maximum amount of energy is captured as the sun moves in the sky. Engineering technicians who work in the research and development of solar panels or machines will build or set up equipment, prepare and conduct experiments, collect data, and calculate or record results. The production process for photovoltaic panels is more complex than for CSP components, and it involves complicated electronics. Soldering and brazing workers use a metal with a lower melting point than that of the original piece, so only the added metal is melted, preventing the piece from warping or distorting. Solar photovoltaic panels are also covered in protective coatings, and these coatings increase the efficiency of the panels.
They keep production runs on schedule, and are responsible for solving problems that could jeopardize the quality of the components. Prior to beginning construction on a new solar plant, real estate brokers and scientists must ensure the site is suitable and that the proper federal, state, and local permits are obtained for construction of a power plant. Although many atmospheric scientists work for companies that develop large-scale solar projects, some work for smaller consulting firms that provide these services to individual customers who are considering installing solar power in their homes or small businesses.
For a concentrating solar power (CSP) plant, large mirrors are arranged to catch and focus sunlight for power generation, therefore storage tanks, pipes, and generators must be installed before the plant is connected to the electrical grid.
CSP plants are more like typical power plants and require incorporating large steam turbines and storage tanks, plus a large, flat area for the solar array. Panels must be mounted on the ground or on a roof using metal beams, and welders are responsible for attaching these beams together to form the mounts. Concentrating solar power (CSP) plants require more workers than photovoltaic plants; photovoltaic plants can sometimes even be run remotely. In addition, they are subject to possible injuries brought on by falls from ladders, cuts from sharp objects, and burns from hot pipes or soldering equipment. They are responsible for safely attaching the panels to the roofs of houses or other buildings and ensuring that the systems work. When a solar panel system is purchased, manufacturers may provide the buyer with installation services or maintenance and repair work. Continued growth is expected because solar power has many environmental benefits and is decreasing in price, which will allow it to become increasingly competitive with fossil fuels. And as the price of fossil fuels increases, solar power will become more cost effective relative to traditional sources of energy.
In 2009 alone, the residential market doubled in size and three new concentrating solar power (CSP) plants opened in the United States, increasing the solar electric market by 37 percent.[2] Despite this growth, solar power is still a minute portion of total energy generated in the country. Photovoltaic panels have also proven useful for providing electricity to remote locations that are not supplied by a local electric utility. These thin-film solar panels are becoming more common, although traditional glass- or laminate-coated panels continue to make up the majority of the solar panel market.
The wages listed represent the larger industry or industry group that would employ solar power workers, when applicable. For example, solar photovoltaic installers need to have specialized knowledge and training, but many installers have previous experience as roofers, electricians, or construction workers. Efficiency refers to the percentage of available energy that is actually harnessed by the solar cells. Machines do the majority of work: cutting semiconducting materials, such as crystalline silicon, into wafers, turning them into solar cells, and assembling the solar cells into solar panels. Making photovoltaic panels requires the work of many skilled workers, including semiconductor processors, computer-controlled machine tool operators, glaziers, and coating and painting workers. In the solar power industry, they manufacture precisely designed mirrors for CSP plants and many of the components of photovoltaic panels. It is important to prevent the cover from cracking or scratching thereby reducing the efficiency of the solar panel. Photovoltaic plants are less complex, requiring installation of arrays of photovoltaic panels before they are connected to transformers and the grid. Photovoltaic plants are less complex, but are a challenge for engineers to design because the panels are optimally configured to efficiently harvest solar power. They are also responsible for monitoring and repairing compressors, pumps, and generators, and for erecting scaffolding and other support structures, as well as loading, unloading, identifying, and distributing building materials in accordance with project plans.
Solar photovoltaic installers must be able to work with power tools and hand tools at great heights, and possess in-depth knowledge of electrical wiring as well as basic math skills.
Self-employed installers typically have training and experience with installing solar power systems and are hired directly by the property owners or by a construction firm. And as it expands in usage, there will be a growing need for more workers—manufacturing workers to make solar panels, construction workers to build power plants, solar photovoltaic installers to install solar panels, and so on. In 2009, solar power provided less than 1 percent of total electricity generated in the United States. Electricians, plumbers, and solar photovoltaic installers install residential and commercial solar projects. Most modern solar cells can only harvest about 10 to 15 percent of solar energy, with some types of panels capable of 25 to 30 percent efficiency. Engineers use computers extensively to produce and analyze designs, and for simulating and testing solar energy systems.
Besides machines, mechanical engineers also design and test the electric generators and pumps that are used in concentrating solar power plants.
It is the workers' job to set up the systems, add solvents, monitor the equipment, and feed the pieces through the machines. Real estate brokers also consult with atmospheric scientists to determine if the land is suitable for a solar power plant.
Engineers ensure that the land is graded properly and is flat enough to support large arrays of mirrors or photovoltaic panels. When necessary, installers must be problem solvers, able to repair damaged systems or replace malfunctioning components. Finally, material scientists are seeking to create building-integrated solar energy technologies that address common complaints about solar panels taking away the aesthetic appeal of a building because of their large and bulky nature. Safety is a priority when installing solar panels because installers run the risk of falling from a roof or being electrocuted by high voltage. Computer software developers design the software and other systems needed to manufacture solar components, manage the production of solar panels, and control some solar generating systems.
