Question

Give one disadvantage of using a solar cell?

Answer 1

Hint: As we all know that all renewable sources of energy are free to use, and we can extract an enormous amount of energy from renewable sources such as wind, sunlight, ocean thermal energy, etc. This energy will not get depleted as conventional sources.


Complete step by step answer:
Solar energy is a generally clean and green source of life and it is pollution-free, but when it comes to the installation of the solar cell, then a lot of issues are being faced. The solar cell installation cost is quite expensive, and the components of PV modules are complex and intricate. One of the disadvantages of the solar cell is that it takes a lot of space when installed. However, it has been seen that during the portability and development of solar cells, some green-house emissions take place. Also, solar energy is most dependent on weather conditions and sunlight availability.
Additional Information: We must also know that plants also synthesize their energy from the sun. The food molecule from the plant comes from the combination of carbon dioxide and water. Water and carbon molecules are breakdown into glucose which is a form of energy source.


Note: In solar photo modules, the photons from solar energy are used to excite the electrons in the silicon used for solar cells. It generates electric power, which is thereby transferred for commercial and industrial purposes.
