FAQs on Energy from the Sun III Video Lecture - Crash Course for Class 6

1. What is solar energy and how is it generated?
Ans.Solar energy is the energy that comes from the sun's rays. It is generated when sunlight is captured and converted into electricity or heat through various technologies, such as solar panels (photovoltaic cells) and solar thermal systems.
2. What are the advantages of using solar energy?
Ans.The advantages of using solar energy include its renewable nature, reduction in electricity bills, low environmental impact, and the ability to decrease reliance on fossil fuels. Additionally, solar energy systems can provide power in remote areas where electricity is not readily available.
3. How do solar panels work?
Ans.Solar panels work by converting sunlight into electricity through the photovoltaic effect. When sunlight hits the solar cells in the panels, it excites electrons, creating an electric current that can be harnessed for power.
4. What is the importance of solar energy for the environment?
Ans.Solar energy is important for the environment because it produces no greenhouse gas emissions during operation, helping to combat climate change. Additionally, it reduces air pollution and the depletion of natural resources associated with fossil fuels.
5. Can solar energy be stored for later use?
Ans.Yes, solar energy can be stored for later use using battery systems. These batteries capture excess energy generated during sunny periods and release it when needed, ensuring a steady power supply even when sunlight is not available.
