Advantages of solar cells.
Answers
Solar energy is the most abundant, renewable energy source in the world. Solar energy systems refer to technologies that convert the sun's heat or light to another form of energy for use[1][2].
There are two categories of technologies that harness solar energy, Solar Photovoltaics and Solar Thermal.
Solar Photovoltaic (or PV) is a technology that converts sunlight into direct current electricity by using semiconductors[3]. In contrast, Solar Thermal is a technology that utilizes the heat energy from the sun for heating or electricity production[4].
Following are the advantages of Solar Cell:
➨A solar plant is basically a re-newable power source. Hence it is not harmful to the environment.
➨It is very easy to operate compare to other power sources of re-newable type.
➨It does not produce any noise as it does not have any moving parts.
➨It does not generate emissions or radiations.
➨It does not require fuels or water to produce electricity.
➨Solar cells have longer life, about 30 years.
➨PV cells operate in cloudy weather conditions also.
➨It is very cost effective.
➨It needs less capital investment.
➨It is easy to maintain and it requires lower maintenance.
➨Solar cells based plant is based on modular architecture and hence it can be used as small size power source as well as large size power source.
