The albedo effect is how a darker material gets hotter faster than a lighter material. Insolation is the solar radiation from the sun.
sunspots
About 51.
The value will depend on the latitude, but relative to the rest of the year it is at a minimum.
Intensity of insolation refers to the intensity of the sun's rays on the earth's surface. It is a measure of solar energy that is received by a given surface area at a given time.
As the altitude of the sun increases, the intensity of insolation for that area will increase as well.
At the Tropic of Capricorn.
The angle of insolation affects the intensity of insolation directly. In other words, as the angle of insolation increases, so does the intensity of insolation because the Sun is directly overhead at Zenith, giving off direct, or vertical rays. The opposite happens when the angle of insolation decreases, causing a decrease in the intensity of insolation as well.
Since they are at the same latitude it is most likely that something else is making the temperature different than the intensity of insolation affecting the temperature in both areas.
Normal to the Sun's rays, very roughly 1kW per m^2

Direct and diffused insolation.
The higher the angle of insolation (concentration), the more direct sunlight. Think that you have a light bulb lightening up a small bathroom and when its lightening up any other place like a big room ,the intensity is less so you get less light than the bathroom.
Insolation is a measurement of the solar radiation received by a surface over a unit time. Polar regions have the lowest insolation.
The duration of insolation on March 21 is 12 hours daylight. The duration of insolation is dependent on temperature, season and latitude.
