Question

Why are a large number of solar cells joined in a solar panel?
A. To reduce the cost of production.
B. To get more electricity.
C. It's a tradition.
D. None of the above.

Answer 1

Hint: The solar cell is an electrical device that converts light energy into electricity by the photovoltaic effect. Solar cells are smaller in size and have lesser efficiency of conversion of energy. Solar panels consist of a large number of solar cells.

Complete answer:
Solar cells are also known as photovoltaic cells. They can utilize both natural and artificial light and convert them into electricity. Due to their smaller size, their ability to produce electricity is quite low.

The solar cells act similar to electric cells when they are connected to series, the resultant becomes additive and greater. The solar panel uses multiple solar cells connected in series to increase the electricity produced by the system. In the connection of the series the total electricity produced by all solar cells increases.

Hence, the correct option is B.

Note: Mostly, the photovoltaic module (PV) manufacturers produce solar modules of $12$ volts that can be used to charge $32,36\,\&\, 48$ cells in a series of battery packs. They have quite the same nominal current and consist of the same type of basic battery. The main difference between the panels is voltage.
