Green engineering - Essay vitrineIn the contemporary world, many people have installed the technologies to maximally benefit from solar readiness. It is not just now efficient, but a sustainable expertness that can be relied on even in the future. The insolate provides energy in two ways by heating and through get bying. It radiates great amount of energy that travels through space and spreads all through the humankinds surface. Naturally, the inner core of sun produces the energy through a nuclear fusion of the hydrogen and helium atoms, radiates onto the suns surface, and consequently emits electromagnetic radiation onto the earth using a wide variety of wavelengths (Alternative energy kennesaw.edu). Upon reaching the earth surface, it is harvested for greater use in various processes. Solar energy is of great importance in accompaniment the life and processes of plants, as well as those of humans. Specific Aspects of how Solar Energy works There ar two specific technologi es of converting solar energy into electricity. These are the commonly known photovoltaic systems and solar thermic systems. They both employ very distinct mechanisms to produce office from the suns light. Photovoltaic energy This system of sunniness conversion uses solar panel technologies with the photovoltaic cells as the core element in generation of power (European communities 5). Solar panels are devices or modules of a colligateed assembly of photovoltaic cells, with the capability of collecting the sunlight photons for conversion. The solar panels are developed in different sizes of rectangular shape, from which several can be utilise as a combination to produce enough electricity. The solar cells in the panels are made up of semiconductor materials (silicon is very common), whose conductivity can be increased by introducing impurities (European communities 5). Basically, in the presence of light or sunshine, some of the radiant energy that hits PV cells is absorbed an d transferred to the electrons within the atoms of the semiconductor. Because of the continuous transmitting energy from the sun, electrons of the cells ladder to shift from their positions as they move towards a preferential side of attraction in the cells, creating an electric potency that can be collected and channeled (How do solar nwwindandsolar.com). As the electrons move, they create space for others to move into, and because generating the current in the electrical circuit (direct conversion of sunlight into electricity). Generally, once the energy as electricity is produced, the direct current generated and collected is converted through an inverter, into alternating current required to run close to electronic appliances. The electricity can also be used by connecting the inverter to any load, or connect to the battery banks to store energy for further use. Suppose one switches into solar generated electricity using this technology, he has to enquire and seek suitable n umber and sizes of the solar panels that can be placed on the roof s, away from shade, and in a suitable position (South facing installations on the roof recommended), with correct tilt inclinations to benefit
