Renewable Energy Advantages

Introduction The consumption of energy increased significantly in the past century, and with it, the demand for energy supplies increased as well, primarily because the exhaustible sources started to drain compared to its immense need. Therefore, the world was anticipating reliable renewable energy sources, the most common being: 1) Biomass: it relies on organic materials from plants and animals. 2) Hydro-power: that is based on the moving water. 3) Geothermal: using the heat from the core of the earth. 4) Wind: is caused by the movement of the wind. 5) Solar: produced by the collected rays of the sun. The importance of renewable energy is not limited to the need of alternative energy, but it lies in its sustainability and its impact on…show more content…
These electrons create an electrical current, which is harnessed by wires connected to the positive and negative sides of the cell. An individual cell typically produces about 1 or 2 watts of power. The electricity created is multiplied by the number of cells in each panel and the number of panels in each solar array. Combined a solar array can make a lot of electricity for homes or businesses. There are obvious advantages to solar PV technology. It produces clean energy. It has no emissions, no moving parts, it doesn't make any noise and it doesn’t need water or fossil fuel to produce power. And can be located right where the power is needed, even in the middle of nowhere (In fact, some solar panels are made on small portable surfaces, so you can take it with you in case you need it), or it can be tied into the power grid. Solar PV is growing fast, and it can play a big role in the world’s clean energy economy, anywhere the sun shines. Concentrated solar power…show more content…
2) The photovoltaic cell: is situated in the focal axis of the reflective or of the lens. The PV cell is composed of two or three layers of different materials each part optimized to convert all the electromagnetic spectrum of sunlight into electricity. 3) Dispersant warmth: The high concentration of solar radiation produces very high temperatures. Although the CPV cells energy production is not affected by high temperatures any more than conventional silicon PV, the excess heat is to be evacuated. The PV cell is coupled to copper and aluminum foils for the heat dissipation. 4) Solar tracking system: The module should be perpendicular to the sun, Therefore, the panels require solar tracking systems that follow the sun’s path. The systems typically used have two axes of movement, one to follow the sun from east to west and another to follow the sun from sky to ground. 5) Inverters: Inverters are another key component that impacts the plant cost, design, and performance. Inverters electronically convert the electrical characteristics of a DC power source to AC to be injected into the distribution grid. In many cases, inverters are part of the monitoring
