  • Solar cells convert solar energy into electricity. Silicon is used for making solar cells, which is abundant in nature, but availability of the special grade silicon for making solar cells is limited.
  • The entire process of manufacture is still very expensive, silver used for interconnection of the cells in the panel further adds to the cost. The principal advantages associated with solar cells are that they have no moving parts, require little maintenance and work quite satisfactorily without the use of any focusing device.
  • Another advantage is that they can be set up in remote and inaccessible hamlets or very sparsely inhabited areas in which laying of a power transmission line may be expensive and not commercially viable.
