Solar radiation is the stream of energy from the sun that powers the Earth. Solar radiation includes ultraviolet (UV), visible, and infrared (IR) light. The efficiency of solar panels depends on the intensity and duration of sunlight. Solar radiation plays a crucial role in climate research and weather patterns.
Understanding solar radiation is essential for harnessing the sun’s energy; this article explains its nature, how it affects the Earth, and its significance in solar power generation. Solar radiation is the stream of energy from the sun that powers the Earth. Solar radiation includes ultraviolet (UV), visible, and infrared (IR) light.
Variations in solar radiation—both spatial and temporal—affect regional climates. Areas closer to the equator receive more direct, intense sunlight year-round, contributing to warmer regional temperatures. At higher latitudes, the angle of the sun’s rays is more oblique, resulting in lower intensity and cooler climates.
As solar PV installations move beyond the mid-to-high latitudes of the United States, Europe, and China into hotter lower-latitude regions like Africa and Southeast Asia, PV systems will encounter higher dust levels, temperatures, and solar irradiance.
Power generation presents a stair-like distribution with the increase of solar radiation. The air temperature 15 °C is a critical point. When the temperature is lower than 15 °C, the power generation is more sensitive to changes in solar radiation.
The average annual solar radiation arriving at the top of the Earth's atmosphere is about 1361 W/m 2. This represents the power per unit area of solar irradiance across the spherical surface surrounding the Sun with a radius equal to the distance to the Earth (1 AU).
