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.
This has led to a switch from using conventional means to generate power to the new renewable energy source. Researchers has developed cost efficient ways of collecting and storing solar energy (Solarenergy.com 2014). The invention and development of solar panels and batteries enhances the harnessing and storage of energy from sun. Solar array panels are being utilized in harnessing radiant energy and then the collected energy is stored in the batteries simultaneously. The stored energy can be used to operate the machines and run
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)
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.
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.
The sun is a very valuable source to the world today. We use it for heat, plants use it to grow, and energy such as solar power. Solar power is the conversion of sunlight into electricity. Solar power is the next alternative to all other sources of energy out there. Fossil fuels such as oil and gas are non-renewable, which means they are limited.
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!
Of course the solar energy have some disadvantages too, but it contains quite of advantages also or few more. Solar energy is sustainable sources as long as sun exists, it is renewable, it does not pollute environment and nature, and it has low maintenance. So sun energy should become our main source of producing electricity. Solar energy works with solar panels. Solar panels are made of photovoltaic cells, what convert sunlight into direct current electricity throughout the day.
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
There are not enough fossil fuels sources left on the earth for future generations. On the other hand, renewable energy has a positive impact on economic growth such as business, goods, and jobs. For example, Solar and wind power industries are creating jobs as renewable energy is continuously growing. Renewable energy is clean source of energy that is unlimited and will never run out. Overall, the government should replace fossil fuels with renewable energy in order to protect the environment and create more jobs.
