Solution

The correct option is C

Both A and B are true.


  1. A solar cell is a photoelectric cell that converts light energy into electrical energy.
  2. A single solar cell can produce a potential difference of less than a volt and a current of the order of a few milliamperes.
  3. In a solar panel, many solar cells are connected in series and parallel arrangements to obtain large potential differences and large current.
  4. Similarly, as the surface area is increased more solar energy is captured and more electrical energy is produced by the conversion of light energy.
  5. Example: There are arrays of solar cells on satellites that are used to supply electric power to their electrical systems. These arrays of solar cells can supply power even to a house for domestic usage when arranged in series and parallel, and the surface area of the solar cells is also increased.

Thus, the solar panel's power depends on the arrangement of the solar cells in it & the extent of the surface area of the solar cells.

Thus, option (C) is correct.
