About 50% of the Sun's energy that reaches Earth makes it through the atmosphere to the surface. The atmosphere absorbs and scatters some of this energy, with factors like clouds, aerosols, and gases influencing how much sunlight reaches the ground. The portion that does reach the surface is crucial for supporting life, driving weather patterns, and generating renewable energy.
Mars receives about half as much sunlight as Earth due to its greater distance from the Sun and its thinner atmosphere, which does not effectively trap heat. This results in colder temperatures and less solar energy available for photosynthesis and other biological processes.
All things being equal, sunlight on Mars at aphelion would be about 36% as strong as sunlight on Earth. But Mars has a thinner atmosphere, so this will brighten it a little. Because your eyes adapt to the available light, the difference would be less noticable. Without a brighter comparison (sunny day vs. cloudy day here), the light would not seem intrinsically less. Since the Sun shows a smaller disk on Mars, shadows are sharper.
Sunlight reaching Earth is most affected by the law of reflection and refraction. Reflection is when light bounces off an object, and refraction is when light changes direction as it passes from one medium to another. Both of these phenomena play a crucial role in determining how much sunlight reaches Earth's surface.
We now know that Mars once had liquid water on its surface and probably had a much denser atmosphere than it does now.

Mars has no liquid surface water.
The amount of solar energy absorbed at the Earth's surface is most influenced by factors such as the angle and intensity of sunlight, the presence of clouds, air pollution, and surface properties like albedo (reflectivity) and vegetation cover. These factors determine how much sunlight reaches and is absorbed by the surface.
Mars is always further away from the sun than the earth is. Therefore, the light that reaches the surface on mars is much weaker than on earth, so solar panels are not quite as effective.
Jupiter receives very little sunlight. About 5 Astronomical Unit (AU) or 1/25th the amount of sunlight that the Earth receives, reaches the surface of Jupiter.
It does get sun but not as much as mercury and Venus
Sunlight is composed of three types of ultraviolet (UV) light: UVA, UVB, and UVC. UVA accounts for about 95% of the UV light that reaches the Earth's surface, while UVB makes up the remaining 5%. UVC is absorbed by the Earth's atmosphere and does not reach the surface.

Because there is no sunlight that far down.
its about just 1%
