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.
