Solar Panel For The Greenhouse Effect

A solar photovoltaic power system is a technology that converts the energy from sunlight into electrical energy. Residential solar photovoltaic systems can offset much of a household's power needs, depending on the size of the system and the household's needs. The output power from is directly proportional to power received from the sun, which varies throughout the day and year. The rated maximum output of the module might be achieved only occasionally, depending on actual site conditions. It is a renewable source of energy that is sustainable and totally inexhaustible. Solar energy is also a non-polluting source of energy that doesn’t emit any greenhouse gases when producing electricity.

Even though this work presented in this paper analyzes PV arrays at a very sophisticated level, some basic understanding of the electrical attitude and characteristics of individual PV cells is needed to obtain the big picture. This section contains brief explanations of the PV cell. First, Section 2.1 covers single-diode equivalent circuit model of a PV cell and current-voltage characteristic (I-V). Second, the most common models of PV module performance are discussed in Section 2.2. Last, solar cells connections are described in Section 2.3.

With the dawn of the energy crisis upon us, photovoltaic technology has become a crucial component of discussions centering around sustainability, clean energy, and renewable recourses. This is because there are a number of significant advantages associated with photovoltaic technology. First and foremost, this technology channels our Earth 's largest renewable energy source- the sun. In itself, the sun 's net solar power input to the Earth is more than 10,000 times humanity 's current rate of use of fossil and nuclear fuels. Thus, the energy source harnessed by PV technology is virtually inexhaustible,

A photovoltaic (PV) array is a power system designed to supply usable solar energy by means of photovoltaics. It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity. Solar energy is radiant light and heat from the sun that is harnessed and used especially in the field of power generation. One of the major sources of renewable energy at present times, solar energy has been of interest throughout the world particularly due to its availability in significant magnitude in comparison to other renewable sources.

The South African power crisis needs little introduction as most of us spend our nights in the shadows singing “Hello Darkness My Old Friend” and ‘’I’ve Got the Power ’’ in the hope that at some point the glorious rays of light will return. This energy crisis sees little end in sight and leaves the people of our country with a need and responsibility to find alternative sources of energy - solar power is one of these solutions. Solar power is a brilliant idea as it harnesses the power of the sun and converts it into electricity, however it is very costly and it is inefficient because only 11 - 15% of the energy harnessed is converted into electricity. Solar panels are generally fixed at one position, usually at the angle that one’s roof slopes or at some other predetermined fixed position. According to research, by moving the panel with the sun there will be a marked increase in the efficiency and power output of the solar panel. It is also claimed that temperature will affect the amount of energy produced. Thus, this project will aim to find out if there is a significant difference in efficiency as the sun moves around the solar panel and attempt to obtain the best possible efficiency by moving the panel with the sun throughout the day. By knowing this, it can be used by South African citizens to increase power, lower costs, lower the strain on ESKOM’s grid and improve their investment in solar panels.

Abstract: The current energy situation with fossil fuels as the main source of the world’s energy has two main flaws: fossil fuels contribute to global warming via the greenhouse effect and they are limited in the quantity that remains. Solar power solves both of these problems and can be captured by utilizing photovoltaic cells. However, photovoltaic cells have their own drawbacks due to their high costs of installation and maintenance.

Although the price for installing Solar Powers Systems is high, in the future years solar panels have potential not only return on their investment, but to save you significant amounts of money by not paying for electricity bills. Solar Panels or cells use photovoltaic effect to convert the energy of light directly to electricity. Solar cells are constructed from a semiconductor material, that is usually silicon. Each solar cell contain many electrons. The electrons are not able to carry an electrical charge in their natural state. Photons are being delivered within the suns rays, and when these photons reach the electrons, the electrons are turned into conduction electrons, what means that they are able to carry electrical charge to the

Solar energy is now a great source of renewable energy. Due to the limited stock of fossil fuel, solar panel systems become more popular day by day. Now Industries, houses and defensive forces are using solar panel systems to generate power. The solar panels generate power from sun radiation. Solar cells are also known as Photovoltaic (PV) cells. When sunlight with a specific frequency hits metal, loosely bound electrons emit from the metal as shown in Figure 1. A potential difference is created in between the cathode and the anode. When the anode and the cathode connect, current flows. Solar panel systems use this mechanism to generate power. Then, generated power is carried out to the battery to store and distribute to the load. The main obstacle for solar panel systems is night and cloudy weather, due to low solar radiation.

The term ‘photo’ means light and ‘voltaic mean electricity. A photovoltaic (PV) cell is also known as solar cell. Even though, photovoltaic effect was observed in 1839 by the French scientist Edmund Becquerel, it was not fully comprehensible until the development of quantum theory of light and solid state physics in early to middle 1900s. Since its first commercial use in powering orbital satellites of the US space programs in the 1950s. While most PV cells in use today are silicon-based, cells made of other semiconductor materials are expected to surpass silicon PV cells in performance and cost and become viable competitors in the PV marketplace

The aim of this literature review is to review other scholar 's literature in the area of new energy application on electricity, with a focus of solar panel, and compare with the traditional electricity supply and generate(analysis). Finally, the adopted academic literatures will be reviewed at the end of this part.

In brewing industry, 80% of overall final energy consumption is used in the form of thermal energy where solar thermal can be used for brewing processes as below: steam generation, malting process, stopping germination of grains, air cooling, conservation with hot air, power supplying of washing machines, wither and kiln processes. Malting plants and breweries consume heat for their thermally driven processes at temperature level ranges between 25°C to 120°C. It seems feasible to supply heat at this temperature level which is not higher than the actual amount required but in reality the it is often decided by the consumer which needs the highest temperature. The integration of solar renewable energy system is necessary to reduce the exergy losses and CO2 emissions [17,21,24,25].

As we all know that, history of solar energy is as old as the humans. Since last two centuries human beings started to use it in order to generate electricity. We get electricity form the sun, directly by some simplest processes or else we can get it without any processes too. ‘Many materials produce small amount of electricity when they are exposed to the light’ – this was discovered by Alexandre Edmond Becquerel in 1839. Photovoltaic (PV) converts sunlight into electricity. Sunlight based power is apparently the cleanest, most dependable type of renewable energy accessible, and it can be utilized as a part of a few structures to control your home. Sun powered controlled photovoltaic (PV) boards change over the sun 's beams into power by energizing electrons in silicon cells utilizing the photons of light from the sun. This power can then be utilized to supply renewable energy to our homes. Solar panels are the devices that convert light to electric energy, which are called "solar" panels. The powerful source of light is available from the Sunlight, which are called Sol in technical world.

In the last decades energy consumption have come to a time where people started noticing the climate changes and the effect of fossil fuel energy for been environmentally destructive, by producing pollutions and other effect. After realizing the effect engineers come up with solar panel, an alternative to fossil fuel energy but less harmful for the environment and the pocket. Solar panels which uses renewable energy like the sun to light homes heat and produces electricity. Unlike fossil fuel solar panels are less harmful for the environment. From it creation few decades ego, just recently solar panel started getting popularity in homes in the United States and around the world. When it was invented people were not interested about it, because of the high installation price, however the price have changed dramatically since then. Even though scientific data shows that solar energy is a better alternative to fossil fuel, many people still wondering about global warming, the benefit and the necessity of solar panels

There is basic knowledge known about solar power, but do we know as much as we should? The answer is no. Citizens and everyday people living in the United States do not know as much as they should about solar power. Because these people do not know as much as one should, the government should allow more money to be spent on researching and finding improvements to solar power for several reasons. Despite how much knowledge we know about solar power, the US government should fund research for solar power to better the environment.
