The evaluations of advantages and disadvantages of solar system
While the majority of the world power supply by fossil fuels, such as oil, coal and natural gas, these traditional energy now are facing a number of challenges including the pollutions, rising prices and the limitation of fuel supplies. As a result of these challenges, the alternative renewable power source has been chosen. The reason why solar power becomes a trendy source is that the solar power not only renewable but also has technology development in the future. However, it still has several problems to use this energy generally. This essay will show the limitations of using the solar power system, which including weather dependent, space requirement and the high cost. These drawbacks can be minimized in three ways: Firstly, by using the new innovation which can reduce the effect of weather changing. Secondly, by using the PV system to reduce the space required. Finally, people can apply for the government scheme to release the financial pressures from installing domestic solar systems.
One of the most urgent problems is that the solar system is weather dependent. Although the system can still collect solar energy during cloudy and rainy days, the efficiency of it drops. The solar panels are dependent on sunlight to collect the solar energy. Therefore, the weather can have a significant effect on the energy system. To solve this problem, nowadays, a new table is designed to generate power by using solar
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.
Solar energy is defined as the transformation of the sun’s rays into useful forms of energy, for instance, electricity and heat. The capacity of solar radiation a place receives depends on a variety of factors such as geographic location, time of day, season, and local weather. According to Knier (n.d.) photo voltaic and concentrating solar power cells are the two forms of sources to produce electricity. Photo voltaic cells generate electricity directly using solar cells and concentrated solar power cells generate electricity using steam. According to The World Bank - for the past three years, India has taken a enormous step in forwarding and in implementing the green growth agenda by producing 2,000 MW of solar power at the world’s cheap tariff. Solar power is likely to reduce India’s usage of imports of diesel and coal. A number of measurements are probably taking to generate 20,000 MW of solar power in future by 2022. The Solar industry is likely to create 200-400 jobs in the industries like research, development and installation, for every 10 MW of solar power generated. Hence, the government of India had taken enormous steps to increase the productivity of the solar energy. This research report will discuss the effectiveness and the limitations of solar power in India
The sun is a massive burning ball of hydrogen that outputs gigantic quantities of energy every second. Sunlight is an excellent energy source and the future of using solar power is very exciting. The Sun's energy can be used to heat and cool buildings, generate electricity, operate communication, and GPS systems and even power solar cars. The sun’s energy is clean and solar panels used to harness the energy are low maintenance.
The increase in oil prices, the depletion of fossil fuel, and increase in consumption of energy has led to finding an alternate source of electricity generation through sustainable energy resources. The sun was humankind's first source of power, and with a little effort to make it more efficient, it may be the only source of energy we may need for the future. Among various sustainable sources, solar energy is the fastest growing,
The sun is the source of all life on Earth. In just one hour the sunlight hitting the earth’s surface provides enough energy to power the global economy for a full year (Brown, 2015). The sun will continue to burn for billions of years, making it an unquestionably reliable source for renewable energy. Modern-day photovoltaic (PV) solar cells rely on the photoelectric effect, a phenomenon where light is used to free electrons from a solid surface - usually silicon - to create electricity. PV panels are typically installed on homes and buildings, or in ground arrangements, sometimes called solar farms.
Solar power is not consistent or reliable enough to be the only option for power. This technology relies totally on the sun so certain days we will be able to produce more power than others and at night we might not be able to produce any. Which is why we will not be able to completely sever the tie to conventional power generation. There has to be a method available to generate enough power to meet demand without available sunlight. Although as technology progresses we may soon be able to generate power from solar sources 24 hours a day. Modern solar power towers are being designed to store excess heat transfer medium underground during the day as its heated and recycling it at night to continue to generate steam for power production (Mills, 2004). But even with this ability we will not be able to go solely to solar power but it can still supplement existing power and drastically reduce the country’s carbon
Commonly, renewable energy is defined as energy which is able to be captured from existing natural resources that are replenished rapidly, such as flowing water, sunshine, wind, geothermal heat flows and ocean [2]. Renewable energy technologies are required to provide technologies to use one or several renewable energy resources. There are some different types of renewable energy technologies, which include solar energy, bioenergy, hydropower, wind energy, geothermal energy and tidal energy. This thesis project will focus on the solar photovoltaic which is currently one of types of solar energy technologies, and this technology using photovoltaic cells to converts sunlight directly into electricity.Solar photovoltaic system can generate electricity from sunlight through using PV modules, and the system can be integrated into building designs, installed on rooftops, or large scale power plant. With the development of photovoltaic technologies, solar photovoltaic capacity has been increased from 3.7 GW (2004) to 177GW (2014) [3]. Figure 2 shows this change from 2004 to 2014, there is a big trend of increase in these years. The increase of PV capacity can reduce the carbon emission and provides more job opportunities. It also helps to reduce air pollution and make a friendly environment for living. One of the common PV system is
Analysis of Building a Functioning Solar Panel that Could Produce Energy on Cloudy, Sunny, and Overcast Days.
It is one of the cleanest sources without any emission of harmful gases and is in a great demand today. When these are converted to electricity for commercial as well as residential uses, there are no effects on the environment, no air pollution, noise pollution or any wastes. These can play a very important role in reducing greenhouse gas emissions by replacing coal-powered energy sources with clean, renewable solar technologies which improve air quality and lessen the harmful impacts that contribute to climate change. Residential solar gives the advantage of energy independence, fuel diversity, improved power reliability, increased price stability and reduced need to build more expensive and polluting electric power generation plants. The benefits of this are energy independence, protection against rising electrical rates, sound financial investment, reduce pollution and dependence on foreign oil. These benefits extend well and eliminate exposure to increasing energy costs and Solar power provides energy security. Photovoltaic (PV) power systems convert sunlight directly into electricity and enables homeowner to generate some or all of their daily electrical energy demand on their own roof, exchanging daytime excess power for future energy needs. It can plan an important role in providing an alternative source of electricity, energy, and back-up power for homes, offices, commercial and industrial buildings. Those who are putting solar on their homes, businesses or other buildings are making a
In addition, solar energy operational costs are manageable. It is free from monthly charges compared to conventional sources of energy. Solar energy does not require raw materials such as oil and coal, and once the panels are built, there will be no monthly charges. In addition, the prices of fossil fuels are increasing day by day, and this means conventional energy will be very expensive. Solar energy will remain the most capable world’s future power supply because, it is cost effective once the plants are built, and there will be no transport costs like for conventional energy sources. Therefore, solar energy is cost-effective, and will help in future energy supply, as the maintenance cost is affordable, as long as they are installed properly, and are working efficiently ( Hans, 2012). Furthermore, with the improvement and advancement of technology, it will increase its efficiency, and cost of production thus, making it more cost effective and the world’s best
Almost everyone has heard of solar energy already. Although it is very well known, it has to be used by many people. The biggest problem is the cost of solar energy. There are only a select few who use solar energy. Solar energy has many benefits, but when one sees the price of solar energy, they turn their head the other way. In the beginning, solar cells were extremely expensive to make. They were used in special applications, such as aircraft. Performance mattered more than the cost of making solar cells. However, it is less expensive to make. This is where the problem lies, how to increase efficiency while keeping the manufacturing at a low cost. The energy consumption of solar energy falls below one percent of total energy consumption.
With the reduction of the dependence on fossil fuels, countries and citizens are looking for a way to fulfill their energy needs. Many turn to solar
In order for one to further understand the importance of solar energy, the problem of global warming must be explained. As defined by Webster’s Dictionary, “Global Warming” is an increase in the earth’s average atmospheric temperature that causes corresponding changes in climate and that may result from the greenhouse effect. With an average increase in atmospheric temperatures, our planet is slowly deteriorating. In order to stall or halt this global destruction, countries must turn to solar energy as a cleaner alternative to the depletion of fossil fuels. Solar energy creates a homeostasis for the climate. Due to its ability to decrease global climate changes, solar power can address global warming in several ways.
Solar energy and its use isn’t new to the world. It has been used by various societies beginning from 7thCentury B.C, when the sun’s heat was concentrated by glass and mirrors to light fires. Today, we have everything from solar-powered buildings to solar-powered vehicles. By and large solar technology has some environmental, economic, psychological and ethical implications for our society. Actions taken by companies and individuals to increase the use of solar technology will create good local jobs, improve our environment and reduce our dependence on foreign oil while doing what’s ethical and moral for our society.
Solar energy may define as the energy received by the earth from the sun. This solar energy is in the form of solar radiation. With the help of solar cells, solar radiation can convert into electricity. Sun is a highly powerful energy source, humans and natures are directly depending on the sun. For example in hydro-electricity the solar energy needed for the evaporation of water after that it returns to earth as rain and provides water in dams. In biomass, the solar energy used that process. Solar cells directly converted solar radiation into electricity, during the process time there is no noise or pollution are there. These cells made with some semiconducting materials. If use solar cells in our home it will help to reduce the greenhouse gas emission, minimise the percentage of carbon dioxide in our atmosphere and mainly reduce the necessity of fossil fuels and natural gas use to produce electricity. According to the Ben Sorensen, solar energy is one of a good source of substitute energy, for the reason that it is renewable, economical and does not pollute our environment. Thus, this essay will be divided into three parts. Firstly, we will talk about fossil fuels and its demerits. Secondly, we will look at the issues and implications of solar energy. Finally, we will focus on the advantageous and disadvantageous of solar energy respectively.
