This principle works the other way around at sunrise.
If the sun is just above the horizon or if the sun is low in the sky, and there are no clouds blocking the sun's rays, the sun has much less heat radiation power than if the sun is high in the sky.
This can be explained PERFECTLY from the FLAT earth REALITY with a sun that is 'only' about 32 miles (51.4 km) wide, and which moves several thousands of kilometers away from us above the flat earth, when the sun is shining over our part of the Earth.
When the sun is high in the sky at noon, then the distance from the sun to the observer is the shortest, resulting in maximum solar power.
According to the deluded globe-earth supporters and their 'scientists' the differences exist in solar power, related to the time of day, and related to the position of the sun in the sky, because the sun at a lower position in the sky must shine through thicker layers of atmosphere, while their GIGANTIC sun is no less than 92,955.807 miles (149,597,870 km) away from the earth, which is so far away that it shouldn't matter what position the sun is in the sky, concerning the solar radiation power.
THE EARTH IS FLAT!
