The Power of the Sun - media.nationalgeographic.org
Solar power—the conversion of sunlight into electricity—is yet another application of solar technology. This can be done in a number of ways. The two most common are photovoltaic (solar cells) and concentrating solar power. Solar cells convert sunlight directly into electricity. The amount of power generated by each cell is very low.

that a small increase in temperature leads to a large increase in radiated power. Example 1: The sun has a radius R = 6.95 x 108 m and a surface temperature of 5800 K. Calculate the total power radiated by the sun's surface, treating it as a perfect radiator. Solution: This is a simple application of the Stefan-Boltzmann law with α = 1.

The Power of the Sun The sun is a star filled with gases that create energy. This energy makes the heat and light the sun gives off. It only takes eight minutes for the sun’s light to get to Earth. That’s pretty fast, considering the sun is about 93 million miles away! Along with the light and heat, Earth uses the sun to grow plants and keep us

Astrophysicists classify the Sun as a star of average size, temperature, and brightness—a typical dwarf star just past middle age. It has a power output of about 1026 watts and is expected to continue producing energy at that rate for another 5 billion years. The Sun is said to have a diameter of 1.4 million kilometers, about 109 times the ...

The Sun’s internal structure can be described in terms of several zones or layers (Figure 2). At the heart of the Sun is its core, which extends from the center to about one-fourth of the way to the surface. The max-imum temperature in the core is over 15 million K, and this is where almost all of the Sun’s energy comes from via nuclear fusion.
