Week 5: INTRODUCTION


Solar energy is the energy that is obtained from the sun. This energy helps and supports all life and Earth. Heat and light from the sun, along with solar based resources such as wind and wave power, hydroelectricity and biomass, account for most the available flow of renewable energy. Solar power is becoming popular, as a friendly environment renewable energy sources that produces no pollution, requires minimal maintenance and free energy from the sun. Solar energy has a wide variety of technologies and is flexible for different application. One types of solar energy is solar photovoltaic power. For example are the residential, commercial, industrial, agricultural, and transportation sectors.

Photovoltaic’s (PV) is a method that to generate electrical power by converting solar radiation or solar energy into direct current electricity using semiconductors that exhibit the photovoltaic effect. Photovoltaic power generation employs solar panels comprising a number of cells containing a photovoltaic material. Materials that are used for photovoltaic’s include monocrystalline silicon, polycrystalline silicon, amorphous silicon, cadmium telluride, and copper indium solenoid/sulfide.

         These solar photovoltaic systems are friendly to environment and can also be used to improve power quality and increase the reliability of the electric power system.
