Max Solar Insolation in Tropics
The region that receives the maximum solar insolation per unit area is the Tropics. This is because of the following reasons:
Position on Earth
The Tropics region lies between the Tropic of Cancer and the Tropic of Capricorn. These two latitudes are located close to the Equator, which receives the most direct sunlight throughout the year. Thus, the Tropics receive more solar radiation than other regions.
Atmospheric Conditions
The atmosphere plays a vital role in controlling the amount of solar radiation that reaches the Earth's surface. The Tropics have a relatively thinner atmosphere, which allows more solar radiation to reach the surface. This is because the angle at which the sun's rays hit the Earth's surface is less oblique in the Tropics than in other regions.
Climate
The climate in the Tropics is characterized by high temperatures and humidity, which increase the amount of solar radiation absorbed by the Earth's surface. This is because warm air can hold more water vapor than cold air, leading to more absorption of solar radiation.
Conclusion
In summary, the Tropics receive the maximum solar insolation per unit area due to their position on Earth, atmospheric conditions, and climate. This has significant implications for agriculture, energy production, and other activities in the region.

- The Equator receives comparatively lesser solar insolation than the tropics despite being at zero latitudes.
- The main reason is the cloudiness of the equator. Generally, at the same latitude, the insolation is moreover the continent than over the oceans, because oceans are cloudier due to greater evaporation.
- Similarly in the equator, evaporation is high, cloudiness is high and rains are frequent. Clouds reflect incoming solar insolation and send it back to space.
