What are 4 types of radiation from the sun?
Solar radiation includes visible light, ultraviolet light, infrared, radio waves, X-rays, and gamma rays..
Where on earth is insolation a maximum on the equinoxes?
equatorAt the equinoxes, solar insolation is at a maximum at the equator and is zero at the poles. At the summer solstice of the northern hemisphere, daily insolation reaches a maximum at the North Pole because of the 24-hour-long solar day.
At what time of year is the duration of insolation the greatest?
The greatest intensity of insolation is during solar noon at both locations. The duration of insolation increases and decreases throughout the year and is greatest during the summer solstice, June 21, when we receive 15 hours of daylight and only 9 hours of daylight on December 21.
What time of day is solar radiation insolation at a maximum?
noonIn the early morning and late afternoon, the sun is low in the sky. Its rays travel further through the atmosphere than at noon, when the sun is at its highest point. On a clear day, the greatest amount of solar energy reaches a solar collector around solar noon.
In which month is the duration of insolation the longest?
June 21stThe duration of insolation varies with latitude and the season of the year. Maximum insolation occurs in the Northern Hemisphere around June 21st (Summer Solstice).
Where on earth is the maximum insolation?
On June the 21st, the Earth has continued its journey so that the maximum overhead sun is over the Tropic of Cancer (23.5° N), and the Northern Hemisphere experiences its maximum amount of insolation received and summer.
What is the duration of insolation?
These slight changes in insolation result only from the annual changes in the altitude of the Sun above the horizon, as the duration of daylight at the equator is always 12 hours. The peaks in insolation intensity correspond to the two equinoxes when the Sun is directly overhead.
How do you calculate insolation?
Solar insolation (I) can be calculated using the following formula: I = S cosZ. The maximum amount of solar insolation on a surface at a specific tilt angle can be calculated with the knowledge of latitude and the day of the year, based on the equation of the sun’s position in the sky throughout the year.
What is the angle of insolation?
The angle of insolation is the angle at which the sun’s rays strike a particular location on Earth. When the north end of the Earth’s axis points toward the sun, the Northern Hemisphere experiences summer.
How do clouds affect insolation?
Low, thick clouds primarily reflect solar radiation and cool the surface of the Earth. High, thin clouds primarily transmit incoming solar radiation; at the same time, they trap some of the outgoing infrared radiation emitted by the Earth and radiate it back downward, thereby warming the surface of the Earth.
Which material absorbs the most solar radiation?
About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system.
On which date does more sunlight hit the solar panel?
Record the following data for the 40° N location: The number of Sun rays hitting the solar panel on June 21 and December 21.
