SSC Selection Post 2025 PYQ — Question 24

Correct Answer

Availability of flat, arid, and sparsely populated land with high insolation.

Explanation

For a grid-connected utility-scale solar farm, the most important geographical factor is the availability of flat, arid, and sparsely populated land that receives high levels of solar radiation (insolation). Such locations maximize solar energy generation while minimizing conflicts related to land acquisition, displacement of people, and environmental impacts.

Flat terrain reduces construction and maintenance costs, arid regions generally experience fewer cloudy days, and sparsely populated areas reduce social and ecological disruptions. High insolation ensures greater electricity generation and improves the overall efficiency of the solar project.

Key Points

• High insolation is essential for maximizing solar power generation.

• Flat land reduces installation and infrastructure costs.

• Arid regions usually receive abundant sunlight throughout the year.

• Sparsely populated areas help minimize land acquisition and resettlement issues.

Additional Facts

• Rajasthan and Gujarat are among India's leading states for large-scale solar energy projects due to their high solar potential.

• Utility-scale solar farms require large contiguous land areas for efficient operation.

• Solar energy is a renewable and environmentally friendly source of electricity.

Important Questions

Question: What is meant by insolation?

Answer: Insolation is the amount of solar radiation received by a given area on the Earth's surface.

Question: Why are arid and sparsely populated regions preferred for large-scale solar farms?

Answer: They receive abundant sunlight and reduce land acquisition, population displacement, and environmental conflicts.
