3. What are the advantages of solar cells over chemical cells for generating electricity?
Are there any disadvantages too?
Answers
Explanation:
Benefits or Advantages of Solar Cell
➨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.
Following are the benefits or 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 .
Disadvantages of Solar Cell
Following are the drawbacks or disadvantages of Solar Cell:
➨It can not be used in absence of the light from any source.
➨It incurs very high initial cost for installation.
➨During cloudy weather, less power is being generated.
➨Very large geographical area is needed in order to deploy solar panels or cells.
➨Off grid applications require energy storage.
➨Photo-Voltaic solar cells generate direct current (DC). It requires DC appliances or inverters (to convert DC to AC) for use with solar cells based plants.
