Question

Explain solar energy.

Answer 1

Instructions:

• Explain how solar energy is generated.
• Explain its uses.

Solution:

• Solar energy​ uses the sun’s light and heat to generate renewable or ‘green’ power. Solar panels or photovoltaic cells harness the most common form of solar energy.
• When the sun’s rays hit the cells, it releases electrons from their atoms. This allows the electrons to flow through the cell and generate electricity.
• Used for heating and lighting purposes. This method benefits a lot of tropical countries, including India. We use this technology to power community lights, traffic signals, and solar cookers.
