Question

Answer the following questions.
a. How can we get the required amount of energy by connecting solar panels?
b. What are the advantages and limitations of solar energy?

Answer 1

a. Many identical solar cells connected together forms a solar panel. Now, many such solar panels are connected in series in a form of solar string to get required voltage. Also, many such identical solar strings are connected in parallel to get the required current. Hence, in this way we get the required amount of energy by connecting solar panels.

b. Advantages of solar energy:

• Solar energy is green energy i.e. it is renewable and does not cause pollution.
• Solar panels for the generation of electricity requires less maintenance.
• With the help of solar energy, electricity is possible to be generated even in the most remote, inaccessible locations where electric power lines cannot be laid.

Limitations of solar energy:

• Electricity generation based on solar energy is weather dependent and hence it is less reliable. In winters and in cloudy days, the production becomes less.
• The whole set-up of the panels requires lot of space to generate considerable amount of electricity.
• The initial cost of a solar panel is sufficiently high.
