A large number of solar cells are combined in an arrangement called Solar Cell Panel.

Principal Advantages:

  1. They have no moving parts.

  2. Require little maintenance and work quite satisfactorily without the use of any focusing device.

  3. These cells can be set up in remote and inaccessible areas where laying of a power transmission may be expensive.
