The Sun provide Earth with large amount of energy enough to power the great oceanic and atmospheric currents, the cycle of evaporation and condensation that bring fresh water in land and drives water flow, and the typhoon, hurricanes, and tornadoes that so easily destroy the natural and built landscape. Sunlight can be converted into electricity by exciting electrons in a solar cell. It can yield chemical fuel via natural photosynthesis in green plants or artificial photosynthesis in human engineered system. Concentrated or unconcentrated sunlight can produce heat for direct use or further conversion to electricity. Figure 1.1 shows the solar photons convert naturally into three forms of energy which are electricity, chemical fuel and heat.
Antireflection coating became an integral part of designing different types of solar cells. Reflections can be minimized in certain wavelengths thus result in higher overall efficiency. In order to understand the working principle behind antireflection coatings, we must first understand the nature of light and it’s interaction with other materials. It is of utmost importance for solar cell designers and researchers to understand both the particle and wave nature of light in order to design a high efficiency solar cell. The Sun’s energy which radiates into the Earth’s surface and harnessed by solar cells are composed of broad spectrum of electro-magnetic (EM) waves combined together which form visible light that have different power densities depending on the wavelength of propagation.
This heat is used directly or converted into mechanical energy and in turn electricity, known as concentrated solar power . This heat is used directly (low‑temperature solar thermal) or converted into mechanical energy and in turn electricity (concentrated solar power – CSP).Heat collect by the panel heats up water (or oil or another fluid) that flows through a circuit of pipes into a copper coil inside your hot-water tank it also power solar cooling systems. A thermal system is usually used for outdoor such as electric motor, heat exchangers, valves, insulation, casing, doors, lamp etc., It is used for a multipart assemblyof coupled components ( some them thermal)
According to (Wikipedia.org 2014) the sun is the most important source of renewable energy available at this time. The sun provides energy for all living creatures on earth. For example, plants absorbs solar radiation from sunlight and converts it into stored energy for growth and development. This process is called photosynthesis.Solar energy is a light and heat from the sunlight collected and converted using a wide variety of technologies such as artificial photosynthesis, solar thermal electricity, solar architecture, solar heating device and solar photovoltaics. Scientists and engineers today works extremely hard to develop ways to utilize solar radiation or sunlight directly by converting it into useful heat or electricity.
Abstract Solar Power Satellites (SPS) converts solar energy in to micro waves and sends that microwaves in to a beam to a receiving antenna on the Earth for conversion to ordinary Electricity. SPS is a clean, large-scale, stable electric power source. For SPS Wireless power transmission is essential. WPT contains microwave beam, which can be directed to any desired location on Earth surface. This beam collects Solar Energy and converts it into Electrical Energy.
Solar thermal energy is the first one, which is the conversion of solar energy into heat. Photovoltaic Solar Power, that converts into electricity. In addition, as the third, Concentrating Solar Power or CSP, which is one type of solar thermal
The second method consists in using concentrated solar heat energy and big power utilities to indirectly make electricity. Solar thermal is the most common way of using solar power. The process of heating water with the sun’s energy is more popular in the areas where it is usually warm and sunny. This is also a greatly useful economic solution. After the solar panels are bought and installed, apart from check-ups, the rest of the process is free!
So the development of alternatives fuel vehicles using cleaner alternative fuels and advanced power systems for vehicles has become a high priority for many governments and vehicle manufacturers around the world. Solar powered vehicles run from solar energy consumption. The engine battery recharges using solar technology. And electric power vehicles use alternative current to charge the battery of the engine. And then runs the engine in Direct current source.
The concentrating solar power plants are converting the sun’ energy into the high temperature heat. The other part of the concentrating solar power is converting the solar energy into heat while the other part converts the solar energy into electricity. The concentrating solar power plants with the large scale are used in concentrating the sunlight by reflection which is opposed to the sunlight refraction. The concentrating solar power is ranging from small kW to the hundreds of MW.The first concentrating solar power was used in California. Most of the concentrating solar power which was installed is
Here, is it discussed about the off grid wind solar hybrid power system and how and why it can be taken into account in Sri Lanka is discussed in a nutshell at the latter part. Producing electricity using solar energy and wind energy? Solar energy: Solar energy is free and also it is the prime source of all the other energy sources and is unlimited. The heat generated by the Nuclear Fission on the sun is radiated onto the earth. This radiation carries a lot of energy which Tis about 10,000 times the energy
