This indicates that India’s future energy requirements are going to be very high and solar energy can be one of the efficient and eco-friendly ways to meet the same.
Solar thermal power generation technologies
Solar Thermal Power systems, also known as Concentrating Solar Power systems, use concentrated solar radiation as a high temperature energy source to produce electricity using thermal route. Since the average operating temperature of stationary non-concentrating collectors is low (max up to 1200C) as compared to the desirable input temperatures of heat engines (above 3000C), the concentrating collectors are used for such applications. These technologies are appropriate for applications where direct solar radiation is high. The mechanism of conversion of solar to electricity is fundamentally similar to the traditional thermal power plants except use of solar energy as source of heat.
In the basic process of conversion of solar into heat energy, an incident solar irradiance is collected and concentrated by concentrating solar collectors or mirrors, and generated heat is used to heat the thermic fluids such as heat transfer oils, air or water/steam, depending on the plant design, acts as heat carrier and/or as storage media. The hot thermic fluid is used to generated steam or hot gases, which are then used to operate a heat engine. In these systems, the efficiency of the collector reduces marginally as its operating
There are four types of concentrated solar plant technologies: Parabolic Trough, Compact Linear Fresnel Reflector, Power Towers, and a Dish-Engine. As Solar Energy Industries Association explains, “Parabolic trough systems use curved mirrors to focus the sun’s energy onto a receiver tube that runs down the center of a trough. In the receiver tube, a high-temperature heat transfer fluid (such as a synthetic oil) absorbs the sun’s energy, reaching temperatures of 750°F or even higher, and passes through a heat exchanger to heat water and produce steam. The steam drives a conventional steam turbine power system to generate
In the process of generation of power sun’s energy is used and also for solar heating and cooling. Solar energy resources are extensively spread and can receive sun light anywhere. While generating the electricity various factors are considered which affects in the generation such as location, weather conditions, time of the day. Greenhouse gases are not emitted during the generation of electricity. (Carey, 2014)
analysis has incontestable that solar energy is a perfect supply for lowtemperature heating applications like area and domestic quandary heating. Solar heating applications area unit intuitive since, once solar power is absorbed on a surface, the surface temperature rises, providing a heating potential. The use of solar energy to supply refrigertion is a smaller amount intuitive.
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 solar industry is divided in three main markets: the European solar thermal market, the Chinese market and the market in other world regions. The industry is segmented in two main types of solar thermal collectors, which are evacuated tube collectors (80 per cent on average of the worldwide newly installed capacity in 2010) and flat plate collectors (20 per cent on average). This industry is characteristic of technology intensive industries with their central innovation: solar thermal water heating which radically reduces costs. They can also count on experimented installers. Each customer adopt and have
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.
Similarly, India is planning to boost solar power from near zero to 20 giga watts by 2020, part of an ambitious $19 billion, 30-year plan to increase the share of renewables in that country’s energy mix.
There are two main forms of solar power: The use of photovoltaic, or PV, cells, and the use of thermal energy from the sun. Photovoltaic cells exploit the photoelectric effect, which converts the protons from the light of the sun into electrons, which can be converted into energy. Photovoltaic energy accounts for fifteen gigawatts of global energy, which is equivalent to fifteen large electric power plants. Also, the production of PV cells has increased by two thousand times over the past twenty years, and it is expected to continue to grow. Solar-thermal energy takes the thermal energy created by the sun and turns it into electricity. Although it only only produces as much energy as one large power plant, solar-thermal energy has many domestic uses. It can not only be used for electricity, but also for solar heating, which uses sunlight to heat up houses. Solar power has already proven to be a reliant source of energy, and it will only continue to improve in technology and
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
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
The future of solar energy technology is poised for significant growth in the 21st century (Union of Concerned Scientists). It has been said that more
Research has demonstrated that solar energy is an ideal source for lowtemperature heating applications such as space and domestic hot water heating. Solar heating applications are intuitive since, when solar energy is absorbed on a surface, the surface temperature rises, providing a heating potential. The use of solar energy to provide refrigeration is less intuitive.
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.
The government of India is promoting the use of solar energy through various strategies. In the latest budget for FY2010-11, the government has announced an allocation of ₹1,000 Crore (US$150 million) towards the Jawaharlal Nehru National Solar Mission and the establishment of a clean energy fund. This is an increase of ₹380 Crore (US$56 million) from the previous budget. This new budget has also encouraged private solar companies by reducing customs duty on solar panels by 5% and exempting excise duty
