Solar Energy Technology and its Policies
Increased energy consumption in the world today is a growing concern. Most of the energy consumption today comes from fossil fuels. Fossil fuels mainly consist of oil, coal, and natural gas as the most commonly used ones. These products are non-renewable sources meaning that one day it will be all used up. But the issues with fossil fuels extend past its eventual finish, the burning of them leads to greenhouse gas emissions and in non-producing countries there is a higher dependency on imports most especially from politically unstable countries who export them. With all the problems fossil fuels bring, the world is trying to find a cleaner and more efficient way of generating energy. That has been partially accomplished with the use of renewable sources such as wind, biofuels, solar, nuclear and the list goes on. In this paper, I am going to concentrate more on solar energy. Solar is the Latin word for sun therefore, solar energy means energy from the sun. Amongst the different renewable sources, solar is one the least used sources in energy production.

Solar is the Latin word for sun therefore, solar energy means energy from the sun. The main equipment used for converting sunlight into electricity is the solar panel. The solar panel is made from solar cells also called photovoltaic (PV) cells. The name is derived from the process of converting light (photons) to electricity (voltage) which is known as
Solar energy is a renewable energy source meaning that the energy is generated by the sun. The way that solar produces energy is by the sun's rays that reach earth and converts into heat and electricity. Its transported by photovoltaic ( pv devices ) and solar thermal electric power plants. Examples of this energy source is : solar powered window blinds, bulbs, refrigerators, radios, calculators,
Solar panel absorbs sunrays as a source of energy to produce electricity. They usually comprise of smaller units known as photovoltaic cells (PV). They are the means of conversion. Electrical energy is converted into mechanical energy by means of a machine called electric motor.
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
With the growing cost of fuel for cars and the rolling blackouts of last summer, the need for an alternative, cost-effective, environment friendly energy source is escalating. Many possible solutions have been presented, such as nuclear power, wind power, and hydrogen fuel cells; prevalent among these is solar power.
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.
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.
Solar energy is created by converting sunlight into electricity using photovoltaics (PV) or the less common
Solar energy is rising throughout the United States. This source is mainly used in remote locations, but is becoming popular in urban areas. In 18 days of sunlight the earth receives an equal amount of energy stored in all of the earths reserves of oil, coal, and natural gas. Solar energy is produced by collecting sunlight with large, flat panels, made up of individual solar cells, and converting the sunlight into electricity. Solar energy is an alternative to fossil fuel and it is important to know the advantages, disadvantages, and the overall price.
Solar energy is the energy from the sun. It uses sunlight to produce electricity. These panels are usually installed on the roof and positioned to face the sun. Most countries all around the world use solar energy to reduce their dependence on fossil fuels and making it as a sizable share of their energy supply. Solar panels are used in large numbers by homes and offices to reduce their monthly electricity bills and reduces the need of electricity from utility companies.
The energy the Earth receives from the sun, primarily as visible light and other forms of electromagnetic power. The term solar energy often refers to processes that use this energy to generate heat or electricity for human use. Just how does sunshine become electricity? Here 's an overview of the solar energy facts, the process, and the equipment that can help you generate your own clean, more affordable energy. The solar panels are made up of photovoltaic (PV) cells, which convert sunlight into direct current electricity throughout the day. A device converts the DC electricity generated by the solar panels into the alternating current electricity. The AC electricity is sent from the inverter to your electrical panel to power your lights and appliances with solar energy. The electrical panel is often called a "breaker box." The utility meter measures your energy use. It actually goes backward when your system generates more power than you immediately need. This excess solar energy offsets the energy you use at night. Your business is still connected to the grid. You’ll need that power from the utility company at night, but don’t worry. The cost is offset by any
Solar power harness the sun 's energy to create electricity. Solar energy assets are enormous and boundless, and they can be tackled anyplace that gets sunlight. The measure of solar radiation, otherwise called insolation, coming to the earth 's surface consistently is more than all the energy at present devoured by every single human activity yearly [1]. Various variables, including geographic area, time of day, and current climate conditions, all influence the measure of energy that can engage in for electricity creation or heating purposes.
Simply stated, the definition of "solar energy" is energy that is created by the sun. In the context of modern usage, "solar energy" may refer to technology that converts radiation from the sun into usable energy sources, such as electricity. In essence, solar panels gather energy from the sun 's rays and send the energy out through a process that results in electricity, that can be used to power homes, machinery and much more. Solar energy is a sought-after source of alternative energy because the sun offers a clean, renewable and cost-effective resource as long as it continues to burn and power life on Earth.
ABSTRACT: Man in his lifetime, uses energy in one form or the other. In fact whatever happens in nature, results, out of the conversion of energy in one form or the other? The extensive usage of energy has resulted in an energy crisis, and there is a need to develop methods of optimal utilization, which will not only ease the crisis but also preserve the environment. Several renewable energy resources like solar energy and wind energy etc. are being used to obtain electricity. But these systems are expensive and also have low efficiency. Another major disadvantage is that these systems cannot be installed everywhere as each of them
Solar panels use small photons packets of energy from rays of sun to generate electricity. Solar panels are made up of photovoltaic cells - (photo = light and voltaic = electricity).
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
