This depends on the time of year. During the summer and winter solstices, the sunlight will be 66.5 degrees. At the equinox, the sunlight will be exactly perpendicular to the ground - 90 degrees.
Never stable as always changing dependant on the cycle of the earth around the sun, the spin of the earth (a cycle each day) on its axis and the position of the wobble of the axis. Mid year generally would be 90 degrees.
At the Earth's surface the strongest sunlight is when the Sun is directly overhead, you are standing on a very high mountain, and the Sun is at perihelion. (See Edit 2. This point, believe it or not, is in Peru at the top of Mt Huascarán.) This point has the least atmosphere for the sunlight to pass through so the rays are the strongest. Just as an aside, this point is also the furthest from the Earth's center due to the Earth's bulge.
Edit 2: Further research found that the mountain top of Chimborazo in Ecuador is really the point furthest from the Earth's center. I stand corrected. All other conditions apply.
The Earth as a whole receives a more or less constant amount of energy from the Sun which varies through the year according to the distance, which varies over a range of ±1.7%, so the energy varies over a range of ±3.4% - maximum in January, minimum in July.
If you are referring to solar energy, then the angle of the sun above the horizon is a primary factor in determining how much sunlight will hit a given area. This varies by the time of day, date, and latitude.
At which angle is the sun's energy strongest when it hits the earth?
That depends on your latitude, the time of year, and the time of day.
At the equator.
SUMMER
It is due to different angle sunlight shine on different part of earth. The Heat gain to earth is from the Sun and loss to space. Sunlight reach earth at different angle and it is peak at the equator. On North and South pole, the sunlight reach surface at very narrow angle and the sunlight per surface area is a lot lesser that on the equator. While heat gain is uneven but heat loss is even that is colder climate at north and south and hotter climate at equator. In addition, earth rotate around the axis that is slightly tilt. It yield summer on northern hemisphere when it tilt down toward sun (sunlight reach at right angle) and winter when it tilt away from sun (sunlight reach at steep angle). Important to note: hotter and colder climate is not about the distance of the sun but angle that sunlight shine on earth.
yes
The sunlight hits the equator at a direct angle. Sunlight glances off the south pole at an angle, so less of it is absorbed.
Because the sun's rays strike the earth at the sharpest angle, concentrating the heat more. The further away from the equator you go, the shallower the angle - making the energy cover a wider area, meaning the energy is less concentrated.

It strikes it most directly at the equator, on average during the year.

Answer:sunlight strikes the poles at an oblique angle. From the polar regions, the sun is low in the sky, so that the sunlight hits the earth at a low angle, as it does for us in the morning and evening. This low angle means that the sunlight is more spread out, and thus warms the surface less. The polar regions of earth are not cooler because they are farther away from the equator, and they are not cooler because they are farther from the sun. The poles are only about 3000 km farther from the sun than is the equator at noon. This is about 0.002% of the earth-sun distance -- hardly significant.

More direct sunlight produces higher temperatures, and less direct sunlight produces lower temperatures.

the sun's radiation is concentrated in smaller area near the equator
The Equator is directly facing towards the Sun, and so the Sun's rays hits the Equator more directly. As you move north or south, away from the Equator, the Sun's ray hit the Earth at a sharper angle. With further to travel through our atmosphere, the rays are cooler when they strike the Earth.
One of the primary factors affecting the unequal heating of the Earth's atmosphere is latitude. Latitude is the measurement of the distance of a location on the Earth from the equator. The further away from the equator that a location resides, the less sunlight that this location receives. It all has to do with the shape of the Earth. Because the Earth is round, only the front most portion receives direct sunlight. If the front is 0 latitude, then as it goes up you get less sunlight at higher latitude.
