At the equator, land tends to receive around 12 hours a day. At the poles, you get months of complete darkness and months of non-stop light. But overall?

I don't think I've answered my own question. At the poles, you get 24 hours of light for half the year! In "sunny" California, it's dark for half of each day. Think :-D

On average everywhere gets 12 hours of daylight / day, but not the same amount of energy of course!

In the tropics, where the Earth's surface is nearly perpendicular to the Sun's rays, each square metre gets more heat and light in the course of a year than near the poles, where the surface is at an oblique angle. This is why it's colder at the poles. It's the flow of heat from the tropics to the poles that drives the world's weather systems, just like the hot combustion chambers and cool exhaust drive a car engine.

The sun is above the horizon half the time everywhere on Earth.
(Actually, it's above the horizon a bit more than half the time, because of refraction in the atmosphere.)
The average elevation of the Sun above the horizon is larger at the equator than at the poles. That's why the tropics are warm and the arctic is cold.

No. The solar index is much lower at the poles. This is due to the angle of the Earth in relation to the sun. Even in summer, the sun is not overhead at the poles, but much closer to the horizon.

The light at the poles is coming in at an oblique angle which affects the amount of light and heat from the sun.

no the poles recieve less overall light in a year

Refraction of light, sun's elevation, seasons, day, night all have a contributing factor in your question.
BUT it cannot be aswered for sure because of met. The wheather , clouds, moisture, rain, and dust...think about it.

No it doesn't because some land could be al covered in trees and is shaded. Overall, I agree with Alicat.

theoretically YES.. but you know that cannot be so because of caves.... ground that is covered by various canopies of over and undergrowth, etc etc
