Photovoltaic array

There are many convieneces to solar power, but of course nothing is perfect. It is more convienet for the consumer because they will not have to purchase things to run their house or car, they could just have the solar pannels themselves and be independent. The one and major inconveience of solar power is what do you do on a cloudy day? Or if one place does not get a lot of sun how can it run? Advantages: Solar energy is a renewable resource that is environmentally friendly. Unlike fossil…

The word “photovoltaic” combines two terms – “photo” means light and “voltaic” means voltage. A photovoltaic system in this discussion uses photovoltaic cells to directly convert sunlight into electricity. A photovoltaic (PV), or solar electric system, is made up of several photovoltaic solar cells. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. To boost the power output of PV cells, they are connected together to form larger units called modules.…

One of the alternative plan is replacing coal-fired energy to solar energy in the industrial factories, in order to reduce the carbon dioxide (CO2), sulfur dioxide (SO2) and the nitrogen oxides (NOx). As most of scientists mentioned, the CO2 is one of the major greenhouse gas that causes the global warming; SO2 and NOx have link to several respiratory illnesses. In order to decrease the temperature globally and the cases of respiratory illnesses, the reduction of CO2, SO2 and NOx are the goals…

Summary background conclusions Summary Of “How Do Photovoltaics Work” Photovoltaics is a term referring to the direct conversion of light into electricity at the atomic level as explained in How do Photovoltaics Work. The way that photovoltaics work is through the property known as the ‘photoelectric effect’ that causes some materials to absorb photons of light and release electrons that are captured, forming an electric current. “The photoelectric effect was first noted by a French physicist,…

Advances in photovoltaic module technology, inverters, system installation practices, and design standards are improving the efficiency of solar systems and have led to the solar system becoming established as a strongly competitive energy source for off-grid energy applications. Substantially reduced Photovoltaic module cost and higher module efficiency compared are playing a key role in this expansion. The…

In its most elementary form, a solar photovoltaic (PV) cell converts solar energy (photons) into electricity (voltage). A solar PV cell is comprised of two doped layers of semiconductor material and generates low-level voltage (less than 1 V). A solar PV module refers to a series of solar PV cells connected together (to generate higher voltage) and laminated into a durable package. A solar panel is formed from the interconnection of several solar PV modules. Finally, a solar PV system is made…

photoelectric effect and the nature of light in 1905. Photoelectric effect state that when photons or sunlight strikes to a metal surface flow of electrons will take place. Later photoelectric effect became the basic principle for the technology of photovoltaic power generation. The first PV module was manufactured by Bell laboratories in 1954. Some 5000 years ago, firstly wind power was used to navigate ships in the Nile. The Europeans used it to pump water and grind grains in 1700s and…

patents, some of them in different countries. Lamb was 28 when he invented the first solar cell. Solar cells were used in streetlights to turn independently on and off, using light. The first actual solar panel was invented in 1932 (Fox, 1997). Photovoltaic modules convert sunlight into DC electricity when sunlight shines on them. Modules are made of glass and either crystal or non-crystal silicon cells. More modules can be added at any time for more power needs. They store all of the…

A French physicist, Edmund Becquerel, discovered the suns energy could produce a Photovoltaic effect (meaning light has the potential to turn into electricity) in 1839. In The 1880s photovoltaic (PV) cells were developed out of selenium that could convert light with one to two percent efficiency (“The efficiency of a solar is the percentage of available sunlight converted by the photovoltaic cell into electricity”) (alt) The way the energy was converted to electricity was a mystery until…

As a result of the global high intensity industrial development, increasing amount of energy consumption is required. Hence this has lead to a situation in rapid depletion of fossil fuels such as oil, coal and natural gas; furthermore the negative effect caused by the greenhouse gas produced when burning fossil fuels must be considered. In order to protect the environment together with maintaining enough amount of energy needed in the future, the world have to depend more on producing renewable…
