State the advantage and disadvantage of using solar cells.

Advantages of using solar cells are:

●Electricity produced by solar cells is clean and silent.


●Photovoltaic systems are quiet and visually unobtrusive.


●Small-scale solar plants can take advantage of unused space on rooftops of existing buildings.


●Solar energy is a locally available renewable resource.


Disadvantage of using solar cells are:


●Some toxic chemicals, like cadmium and arsenic, are used in the PV production process.


●Solar energy is somewhat more expensive to produce.


●Solar power is a variable energy source, with energy production dependent on the sun.
