Concept:

Solar Energy:

• ​The radiant light and heat energy from the sun is harnessed with the use of solar collectors.
• These solar collectors are of various types such as photovoltaics, concentrator photovoltaics, solar heating, (CSP) concentrated solar power, artificial photosynthesis, and solar architecture.
• This collected solar energy is then used to provide light, heat, and different other forms of electricity.

Explanation:

Floating Solar Plants:

• It refers to the deployment of photovoltaic panels on the surface of water bodies.
• They are a viable alternative to land-based solar arrays with applications in India.
• There are a large number of major reservoirs in the Southern Region which provides a huge opportunity to go for renewable energy in the floating solar method.
