* On Earth: The poles receive the least solar radiation. This is because the Earth is tilted on its axis, and the poles are angled away from the sun for much of the year.

* In the Solar System: The outer planets receive significantly less solar radiation than the inner planets. This is because solar radiation decreases with distance from the sun. For example, Pluto receives about 1/900th the amount of sunlight that Earth does.

* Within the Earth's Atmosphere: The higher altitudes receive less solar radiation than lower altitudes, as the atmosphere absorbs some of the radiation.

* On Earth's surface: Areas with cloud cover or during the night receive less solar radiation.

Therefore, to give a more precise answer, you need to specify the context.
